The present disclosure relates in general to audiovisual content distribution, and, in particular to methods, devices, and systems for distributing content in a community of over-the-air broadcast content receivers.
High-definition television (HDTV) digital broadcasting provides superior picture and audio quality compared to traditional standard-definition television (SDTV) broadcasting. A device that receives HDTV content via HDTV digital broadcasting can stream the received HDTV content to various client devices (e.g., cellular telephones, computers, and smart televisions) that have an appropriate application installed for receiving the streamed content. For example, Dish Network and Sling TV currently provide AirTV devices (e.g., AirTV 2 devices) that can stream HDTV content received on local HDTV channels to client devices that support the Sling app. Such devices may stream HDTV content in real time to one or more client devices while the HDTV content is being received via an HDTV antenna. Additionally, such devices may provide digital video recorder (DVR) functionality that enables HDTV content received via an HDTV antenna to be recorded and subsequently streamed to a client device in response to a request from the client device.
HDTV digital broadcasting has several limitations due to the nature of terrestrial systems that broadcast HDTV signals. For example, terrestrial broadcasting systems typically transmit radio frequency (RF) signals from antenna towers that are located in different geographical regions. An HDTV receiver is able to receive HDTV content that is broadcast using HDTV signals transmitted by a local antenna used by a television station only if the HDTV signals transmitted by the local antenna are received by the HDTV receiver with a signal strength that is sufficiently high for the HDTV receiver to decode the HDTV signals. Thus, users of HDTV digital broadcasting can watch HDTV content only if the HDTV content is broadcast in the user’s local region. For example, an HDTV receiver that is coupled to an antenna located in New York City is not able to receive an HDTV signal that is broadcast from an antenna located in the San Francisco Bay Area.
Even if an HDTV antenna is able to receive an HDTV signal that is broadcast from a local antenna, the received HDTV signal may not have a sufficient signal strength to enable an HDTV receiver that is connected to the HDTV antenna to obtain HDTV content from the received HDTV signal. The signal strength of HDTV broadcast signals at an HDTV receiver may be unacceptable for a number of reasons. For example, electromagnetic interference (EMI) caused by nearby power lines and electronic devices may cause the signal strength of an HDTV signal at an HDTV receiver to be unacceptably low. Also, multipath interference caused by RF signals being reflected off of objects (e.g., buildings) may cause the signal strength of an HDTV signal at an HDTV receiver to be unacceptably low. In addition, large amounts of moisture in the air may (e.g., from heavy fog, high humidity, or intense rain or snow) may cause the signal strength of an HDTV signal at an HDTV receiver to be unacceptably low.
Additionally, a user of HDTV digital broadcasting may have trouble getting all local channels that are available in the user’s local region with good signal quality because of the location of the user’s home relative to the various locations of each antenna that is used to broadcast HDTV signals. It may be difficult to place an antenna that receives HDTV signals at an optimum location relative to the location of a particular antenna used to broadcast HDTV signals due to the layout or setup of the user’s home or the area surrounding the user’s home. Also, an optimum location to place an HDTV antenna in order to receive HDTV signals that are broadcast from a first antenna used by a first television station with a maximum signal strength may not be the same location at which HDTV signals that are broadcast from a second antenna used by a second television station are received with a maximum signal strength. Accordingly, users who infrequently watch local HDTV channels may not want to invest the time, money, and effort required to set up an HDTV antenna and associated equipment.
The present disclosure improves conventional content distribution technologies by providing methods, devices, and systems that enable content received via over-the-air (OTA) broadcast signals to be shared among devices located in broadcast regions that are geographically dispersed. For example, the present disclosure improves conventional HDTV digital broadcasting technology by providing methods, devices, and systems that enable a first broadcast content reception device that receives HDTV signals via a first HDTV antenna located in a first region of a country (e.g., New York City) to share locally received broadcast HDTV content with a second broadcast content reception device that receives HDTV signals via a second HDTV antenna located in a second region of the country (e.g., San Francisco Bay Area), which is not possible using conventional HDTV OTA broadcast content reception and distribution systems.
According to the present disclosure, a broadcast content reception device that is unable to receive a particular HDTV content item due to insufficient signal strength of a received HDTV signal can automatically obtain that HDTV content item from another broadcast content reception device in a community of broadcast content reception devices.
In addition, according to the present disclosure, a user can be provided with a single, merged list of local channels that are available from across a community of users located in geographically dispersed regions, for example, spanning multiple zip codes or states. Filters may be used for better classification content included in geographically diverse HDTV channels. For example, the merged list of channels may group together news content items (e.g., programs, broadcasts, episodes, etc.) from geographically diverse HDTV channels so that a user can quickly view all news content items that are available for viewing. Similarly, the merged list of channels may group together sports content items from geographically diverse HDTV channels so that a user can quickly view all sports content items that is available for viewing.

Having described the structure of the community server device 102, the broadcast content reception device 104, and the content player device 106, various functions of the community server device 102, the broadcast content reception device 104, and the content player device 106 will now be described.
In one or more implementations, the community server device 102 stores instructions (e.g., one or more computer programs) that enable it to manage one or more groups or communities of the broadcast content reception devices 104A-104C. In various implementations, the community server device 102 operates as a web server that provides web pages which enable users of the broadcast content reception devices 104A-104C to create communities of broadcast content reception devices, and also enables those users to join and leave those communities by managing membership of those communities. For example, a first community may include broadcast content reception devices 104A-104C, and a second community may include broadcast content reception devices 104A and 104B. The community server device 102 stores community information related to communities that are created, and performs various other functions and services described herein, for example, in connection with
At 202, the community server device 102 generates community information. For example, at 202, the community server device 102 generates the community information in response to a user of the broadcast content reception device 104A using a web browser provided by the content player device 106A (e.g., the user’s cellphone) to access a webpage provided by the community server device 102. The user of the broadcast content reception device 104A may select an icon on the webpage for creating a new community, which results in the webpage displaying a form through which the user can enter information about the new community, information about the broadcast content reception device 104A, and information about the user’s preferences. For example, the user may provide a name for the new community, a user name, a zip code in which the broadcast content reception device 104A is located, an IP address through which the broadcast content reception device 104A can be accessed via the WAN 108, a maximum upload speed or data rate at which the broadcast content reception device 104A will share content items over the WAN 108, a type or a model or a particular capability of the broadcast content reception device 104A, a type or speed of a data connection between the content reception device 104A and the WAN 108, a maximum number of simultaneous streams of content that the broadcast content reception device 104A will provide over the WAN 108, a maximum amount of data per unit of time (e.g., megabytes per second) that the broadcast content reception device 104A will provide over the WAN 108, etc. The community server device 102 generates the community information by associating an alphanumeric community identifier that uniquely identifies the community with the information provided by the user of the broadcast content reception device 104A, and stores the resulting information (e.g., in memory 116). The method 200 then proceeds to 204.
At 204, the community server device 102 receives a request to modify the community information. For example, at 204, the community server device 102 receives a request to modify the new community created by the user of the broadcast content reception device 104A at 202, in response to a user of the broadcast content reception device 104B using a web browser provided by the user’s cellphone to access the webpage provided by the community server device 102. The user of the broadcast content reception device 104B may select an icon on the webpage for joining a selected community, which results in the webpage displaying a form through which the user can enter information about the broadcast content reception device 104B and information about the user’s preferences. For example, the user may provide a user name, a zip code in which the broadcast content reception device 104B is located, an IP address through which the broadcast content reception device 104B can be accessed via the WAN 108, a maximum upload speed or data rate at which the broadcast content reception device 104B will share content items over the WAN 108, a type or a model or a particular capability of the broadcast content reception device 104B, a type or speed of a data connection between the content reception device 104B and the WAN 108, a maximum number of simultaneous streams of content that the broadcast content reception device 104B will provide over the WAN 108, a maximum amount of data per unit of time (e.g., megabytes per second) that the broadcast content reception device 104B will provide over the WAN 108 etc. The method 200 then proceeds to 206.
At 206, the community server device 102 updates the community information. For example, at 206, in response to receiving a request to join the new community from the user of the broadcast content reception device 104B at 204, the community server device 102 adds the information provided by the user of the broadcast content reception device 104B to the community information generated at 202. The method 200 then proceeds to 208.
At 208, the community server device 102 transmits updated community information to a community of broadcast content reception devices. For example, at 208, the community server device 102 transmits the information that is stored at 206 to the broadcast content reception device 104A via the WAN 108 using the address for the broadcast content reception device 104A included in the channel information, and also transmits the information that is updated at 206 to the broadcast content reception device 104B via the WAN 108 using the address for the broadcast content reception device 104B included in the channel information. The method 200 then proceeds to 210.
At 210, the community server device 102 determines whether the method 200 is to end. For example, at 210, the community server device 102 determines whether a shutdown command has been received at 210. If the community server device 102 determines “YES” the method 200 is to end at 210, the method 200 ends. If the community server device 102 determines “NO” the method 200 is not to end at 210, the method returns to 204 and continues when another request to modify a community is received.
At 302, the community server device 102 receives a request for channel information from a requesting broadcast content reception device. For example, the community server device 102 receives via the WAN 108 a request message from the broadcast content reception device 104A that includes the IP address of the broadcast content reception device 104A and the community identifier of the new community created by the user of the broadcast content reception device 104A. The method 300 then proceeds to 304.
At 304, the community server device 102 transmits a request for channel information to other broadcast content reception device(s) in a community. For example, at 304, the community server device 102 transmits via the WAN 108 a request message to the broadcast content reception device 104B that includes the community identifier of the new community created by the user of the broadcast content reception device 104A. Because the community server device 102 may store a plurality of sets of community information respectively corresponding to a plurality of communities, the community server device 102 may obtain a particular set of community information that includes the community identifier and information that identifies the other broadcast content reception device(s) (e.g., IP addresses) using the community identifier included in the request for channel information received at 302, and obtain the information that identifies the other broadcast content reception device(s) (e.g., IP addresses) from that particular set of community information. The method 300 then proceeds to 306.
At 306, the community server device 102 receives channel information from other broadcast content reception device(s) in the community. For example, at 306, the community server device 102 receives via the WAN 108 a response message from the broadcast content reception device 104B, wherein the response message includes a list of channel identifiers and corresponding signal strengths, as described in connection with
At 308, the community server device 102 generates a content list based on channel information received at 306. For example, the community server device 102 queries one or more databases (local or remote) that store content information for content items that are broadcast on each of a plurality of channels in a plurality of broadcasting regions. By way of example, the community server device 102 obtains the zip code associated with the broadcast content reception device 104B in the community information, and performs a series of queries for content information (e.g., name of a television program, genre, unique identifier of television program, etc.) using the zip code and each channel identifier included in the response message from the broadcast content reception device 104B. The method 300 then proceeds to 310.
If the community server device 102 receives a plurality of channel information responses from a plurality of broadcast content reception device (e.g., broadcast content reception devices 104A-104C) at 306, the community server device 102 performs the querying described above for each channel information response. When generating the content list at 308, the community server device 102 may filter the information resulting from the querying so that channel information can be presented to a user in in a convenient form.
For example, the community server device 102 may sort, filter, or group the content items by genre (e.g., news, sports, weekly series, movies, documentary, for children, etc.) so that content items of each genre available from the broadcast content reception device 104A are grouped with other content items of that genre which are available from the broadcast content reception device 104B and the broadcast content reception device 104C. Accordingly, a user that has requested channel information can quickly browse content items by genre, without having to sequentially scroll through all the content items of various genres available from each broadcast content reception device in the community. Other filter types and classifications may be used to arrange content lists without departing from the scope of the present disclosure.
At 310, the community server device 102 transmits the content list generated at 308 to the requesting broadcast content reception device. For example, at 310, the community server device 102 transmits via the WAN 108 a message to the broadcast content reception device 104A that includes the content list generated at 308. The method 300 then ends.
At 402, the community server device 102 receives a request for channel information from a requesting device. For example, at 402, the community server device 102 receives via the WAN 108 a request message from the broadcast content reception device 104A that includes the IP address of the broadcast content reception device 104A, the community identifier of the new community created by the user of the broadcast content reception device 104A, and channel information (e.g., name of channel, unique alphanumeric identifier of channel, channel identifier, name of content item, unique alphanumeric identifier of content item, etc.). It is noted that, at 402, the community server device 102 may receive via the WAN 108 a request message from a content player device. For example, at 402, the community server device 102 receives via the WAN 108 a request message from the content player device 106A including information that identifies the broadcast content reception device 104A (e.g., IP address of broadcast content reception device 104A), the community identifier of the new community created by the user of the broadcast content reception device 104A, and channel information (e.g., name of channel, unique alphanumeric identifier of channel, channel identifier, name of content item, unique alphanumeric identifier of content item, etc.). The method 400 then proceed to 404.
At 404, the community server device 102 transmits a request for channel information to one or more broadcast content reception devices in a community. For example, at 404, the community server device 102 transmits via the WAN 108 a request for channel information message to one or more broadcast content reception devices included in the community that is identified by the community identifier included in the request message from the broadcast content reception device 104A received at 402 (e.g., broadcast content reception device 104B), wherein the request for channel information message includes the channel information (e.g., channel identifier) included in the request for channel information received from the broadcast content reception device 104A received at 402. The method 400 then proceeds to 406.
At 406, the community server device 102 receives channel information from each of the one or more broadcast content reception devices in the community. For example, at 406, the community server device 102 receives via the WAN 108 a response message from the broadcast content reception device 104B, wherein the response message includes the channel information (e.g., channel identifier) included in the request for channel information from the broadcast content reception device 104A received at 402 and signal strength information regarding the strength of a broadcast signal corresponding to the channel information (e.g., channel identifier) that is received at the broadcast content reception device 104B. The method 400 then proceed to 408.
At 408, the community server device 102 selects one of the one or more broadcast content reception devices in the community based on the channel information received at 406. For example, the community server device 102 selects the broadcast content reception device (e.g., broadcast content reception device 104B) that provided a channel information response including signal strength information that indicates a highest signal strength.
By way of example, the signal strength information may indicate a received signal strength in dBm and the community server device 102 may store information regarding the signal strength ranges and corresponding values shown in Table 1. The community server device 102 may determine which of the ranges of signal strengths shown in Table 1 the received signal strength information falls within, and associate the corresponding value with an identifier of the broadcast content reception device that provided the strength information at 406. The community server device 102 may select the broadcast content reception device at 408 by selecting the broadcast content reception device to which the highest value has been associated.
In one or more embodiments, the broadcast content reception device periodically provides statistical information to the community server device 102, for example, in response to a request from the community server device 102. The community server device 102 may store and analyze the statistical information (e.g., including WAN utilization) regarding the broadcast content reception devices. The community server device 102 may select the broadcast content reception device at 408 using the signal strength information received at 406, stored statistical information, and other factors such as the maximum number of streams each broadcast content reception device is configured to share at one time, the maximum percentage of available bandwidth each broadcast content reception device is configured to use for sharing or has actually used for sharing during a given period of time, the maximum data rate at which each device is configured to use for sharing or has actually used for sharing during a given period of time, etc. A numeric weight may be assigned to each criterion in an equation, which the community server device 102 evaluates in order to select the broadcast content reception device at 408.
At 410, the community server device 102 transmits information that identifies the channel and the broadcast content reception device selected at 408 to the requesting device. For example, at 410, the community server device 102 transmits via the WAN 108 a message to the broadcast content reception device 104A that includes information that identifies the channel corresponding to the request for channel information received at 402 and information that identifies the broadcast content reception device selected at 408. The method 400 then ends.
At 502, the broadcast content reception device receives a request for channel information from the community server device 102 (e.g., that is transmitted at 304 of the method 300 shown in
At 504, the broadcast content reception device receives an RF signal from an antenna. For example, at 504, the broadcast content reception device 104A receives an HDTV signal from the antenna 138. The method 500 then proceeds to 506.
At 506, the broadcast content reception device tunes its receiver to a channel. For example, at 506, the microprocessor 122 of the broadcast content reception device 104A provides a control signal to the receiver 132 that causes a local oscillator of a tuner included in the receiver 132 to output a specified frequency such that a signal corresponding to a particular band included in the signal that transmits the channel content received at 504 is output to demodulator circuitry included in the receiver 132 and to signal strength detection circuity included in the receiver 132. The method 500 then proceeds to 508.
At 508, the broadcast content reception device receives information that indicates a signal strength corresponding to the received RF signal. For example, at 508, the microprocessor 122 of the broadcast content reception device 104A receives from the signal strength detection circuity of the receiver 132 information that indicates a signal strength corresponding to an HDTV signal received from the antenna 138. The method 500 then proceeds to 510.
At 510, the broadcast content reception device stores channel information and signal strength information. For example, at 510, the broadcast content reception device 104A stores in the memory 128 the channel identifier included in a list of channels in association with signal strength information that is based on the signal strength indication received at 508. By way of example, and not limitation, the list of channels may be included in the request for channel information received at 502, which may be obtained by the community server device 102 based on the zip code of the broadcast content reception device 104A included in community information. For example, the community server device 102 may obtain channel information included in the list of channels from a database or website that is searchable by zip code for such channel information (e.g., https://www.fcc.gov/media/engineering/dtvmaps). The method 500 then proceeds to 512.
At 512, the broadcast content reception device determines whether there are more channels. For example, at 512, the broadcast content reception device 104A determines whether more channels are included in a list of channels generated by the community server device 102 and included in the request for channel information received at 502. If the broadcast content reception device 104A determines “YES” there are more channels, the method 500 returns to 506 and the receiver is tuned to another channel included the list. If the broadcast content reception device 104A determines “NO” there are not more channels, the method 500 proceeds to 514.
At 514, the broadcast content reception device transmits a channel information response. For example, the broadcast content reception device 104A transmits to the community server device 102 via the WAN 108 a response message that includes the channel information and the signal strength information stored at 510. The method 500 then ends.
At 602, the broadcast content reception device receives a request for channel content. For example, at 602, the broadcast content reception device 104A receives from the broadcast content reception device 104B via the WAN 108 a request message that includes a community identifier and an identifier of a content item (e.g., name, unique alphanumeric identifier, channel identifier, etc.). In one or more implementations, the information transmitted by the community server device 102 at 410 of the method 400 shown in
At 604, the broadcast content reception device determines if it authorized to share the channel content identified in the request for content item received at 602. If the broadcast content reception device determines “YES” it is authorized to share the channel content, the method 600 proceeds to 606. If the broadcast content reception device 104A determines “NO” it is not authorized to share the channel content, the method 600 proceeds to 608.
In one or more implementations, the broadcast content reception device determines if a password included in the request for channel content that is received at 602 matches a stored password, which was previously received from or provided to the community server device 102, wherein the broadcast content reception device 104A determines that is authorized to share the channel content only if the password included in the request for the content item that is received at 602 matches the stored password.
In one or more implementations, the broadcast content reception device 104A determines whether stored community information that is associated with the community identifier included in the request for channel content includes an identifier (e.g., IP address) of the broadcast content reception device 104B that transmitted the request for content item. The broadcast content reception device 104A determines that it is authorized to share the channel content with the broadcast content reception device 104A only if the broadcast content reception device 104A determines that the identifier of the broadcast content reception device 104B that transmitted the request for channel content is included in the stored community information that is associated with the community identifier included in the request for content item.
At 606, the broadcast content reception device transmits the channel content identified in the request for content item received at 602. For example, at 606, the broadcast content reception device 104A streams channel content to the broadcast content reception device 104B via the WAN 108 using the Hypertext Transfer Protocol (HTTP) live streaming (HLS) protocol or the Dynamic Adaptive Streaming over HTTP (DASH) protocol. The method 600 then ends.
At 608, the broadcast content reception device transmits an error message to the broadcast content reception device that transmitted the request for content item received at 602. For example, at 608, the broadcast content reception device 104A transmits an error message including an error code indicating that the broadcast content reception device 104A is not authorized to share the channel content with the broadcast content reception device 104B. The method 600 then ends.
At 702, the broadcast content reception device receives an RF signal from an antenna. For example, at 702, the broadcast content reception device 104A receives an HDTV signal from the antenna 138. The method 700 then proceeds to 704.
At 704, the broadcast content reception device receives information that identifies a channel. For example, at 702, the broadcast content reception device 104A receives from the content player device 106A (e.g., cellphone) a message that includes information that identifies a channel (e.g., a station callsign such as “KOMO-TV”, a network identifier such as “ABC”, a channel number such as “4”, etc.), in response to a user selecting an icon corresponding to a particular television show that the user would like to watch and/or store. The method 700 then proceeds to 706.
At 706, the broadcast content reception device tunes its receiver to a channel. For example, at 706, the microprocessor 122 of the broadcast content reception device 104A provides a control signal to the receiver 132 that causes a local oscillator of a tuner included in the receiver 132 to output a specified frequency such that a signal corresponding to a particular band included in the signal that transmits the channel content received at 704 is output to demodulator circuitry included in the receiver 132 and to signal strength detection circuity included in the receiver 132. The method 700 then proceeds to 708.
At 708, the broadcast content reception device determines whether channel content is to be stored by the broadcast content reception device. If the broadcast content reception device determines that the channel content is to be stored by the broadcast content reception device at 708, the method 700 then proceeds to 728. If the broadcast content reception device determines that the channel content is not to be stored by the broadcast content reception device at 708, the method 700 then proceeds to 710.
For example, at 708, the microprocessor 110 of the broadcast content reception device 104A receives from the signal strength detection circuity of the receiver 132 information that determines whether the information that identifies the channel received at 704 is accompanied by a predefined code (e.g., “00”) indicating that the channel content is to be transmitted to the content player device 106A without storing the channel content, a predefined code (e.g., “01”) indicating that the channel content is to be stored without transmitting the channel content, or a predefined code (e.g., “11”) indicating that the channel content is to be stored and transmitted to the content player device 106A. If the broadcast content reception device 104A determines that the information that identifies the channel received at 704 is accompanied by the predefined code (e.g., “00”) indicating that the channel content is to be transmitted to the content player device 106A without storing the channel content, the broadcast content reception device 104A determines “NO” at 708. If the broadcast content reception device 104A determines that the information that identifies the channel received at 704 is accompanied by the predefined code (e.g., “01”) indicating that the channel content is to be stored without transmitting the channel content or the predefined code (e.g., “11”) indicating that the channel content is to be stored and transmitted to the content player device 106A, the broadcast content reception device 104A determines “YES” at 708.
At 710, the broadcast content reception device receives information that indicates a signal strength. For example, at 710, the microprocessor 110 of the broadcast content reception device 104A receives from the signal strength detection circuity of the receiver 132 information that indicates the signal strength of a signal input to the signal strength detection circuity. The method 700 then proceeds to 712.
At 712, the broadcast content reception device determines if the information that indicates the signal strength received at 710 indicates a signal strength value that is less than or equal to a threshold value. For example, at 712, the microprocessor 122 of the broadcast content reception device 104A determines if the information that indicates the signal strength received at 710 indicates a signal strength value that is less than or equal to -81 dBm. If the broadcast content reception device determines “YES” the information that indicates the signal strength received at 710 indicates a signal strength value that is less than or equal to the threshold value, the method 700 proceeds to 718. If the broadcast content reception device 104A determines “NO” the information that indicates the signal strength received at 710 does not indicate a signal strength value that is less than or equal to the threshold value, the method 700 proceeds to 714.
At 714, the broadcast content reception device transmits channel content based on the RF signal received at 702 to a content player device. For example, at 714, the microprocessor 122 of the broadcast content reception device 104A streams the content item based on the RF signal received at 702 to the content player device 106A using the HLS protocol or the DASH protocol. The method 700 then proceeds to 716.
At 716, the broadcast content reception device determines whether there is more channel content to be transmitted to the content player device. For example, at 714, the broadcast content reception device 104A determines whether all of a content item corresponding to the channel content has been streamed to the content player device by comparing a file size of the content item to an amount of data transmitted to the content player device. If the broadcast content reception device determines “NO” there is not more channel content to be transmitted to the content player device, the method 700 ends. If the broadcast content reception device determines “YES” there is more channel content to be transmitted to the content player device, the method returns to 710 and information is received that indicates a signal strength corresponding to the signal received from the antenna.
At 718, the broadcast content reception device transmits a request for channel information to a community server device. For example, at 718, the broadcast content reception device 104A transmits to the community server device 102 a request for channel information that includes the information that identifies the channel received at 704. The method 700 then proceeds to 720.
At 720, the broadcast content reception device receives channel information from the community server device 102. For example, at 720, the broadcast content reception device 104A receives from the community server device 102 channel information including an IP address of the broadcast content reception device 104B (e.g., transmitted at 410 of the method 400 shown in
At 722, the broadcast content reception device determines if the channel information received at 720 indicates that content corresponding to the channel identified by the information that identifies the channel received at 704 is available from another broadcast content reception device in the community. If the broadcast content reception device determine “NO” the channel information received at 720 indicates that content is not available from another broadcast content reception device in the community, the method 700 returns to 716 and the broadcast content reception device determines whether there is more channel content to be transmitted to the content player device. If the broadcast content reception device determines “YES” the channel information received at 720 indicates that content is available from another broadcast content reception device in the community, the method 700 proceeds to 724.
For example, at 722, the broadcast content reception device 104A determines if the channel information received at 720 includes a predefined error code (e.g., “0000”), which indicates that channel content corresponding to the channel identified by the information that identifies the channel received at 704 is not available from another broadcast content reception device. If the broadcast content reception device 104A determines that the error code is included in the channel information received at 720, the broadcast content reception device 104A determines that the content is not available from another broadcast content reception device. If the broadcast content reception device 104A determines that error code is not included in the channel information received at 720, the broadcast content reception device 104A determines that the content is available from another broadcast content reception device.
In one or more embodiments, the method 700 does not include the acts described above in connection with 718, 720, and 722. Instead, if the broadcast content reception device determines “YES” at 712, the method 700 proceeds to 724, for example, as described in connection with
At 724, the broadcast content reception device transmits a message to a content player device. For example, at 724, the microprocessor 122 of the broadcast content reception device 104A transmits an error message that includes a predefined error code (e.g., “1111”) to the content player device 106A. In one or more implementations, the message transmitted at 724 to the content player device includes information that identifies the community server device 102 (e.g., IP address of the community server device 102), information that identifies a particular community of broadcast content reception device, and the information that identifies the channel received at 704. The method 700 proceeds to 724.
As described in connection with
At 726, the broadcast content reception device stops transmission of the content item transmitted at 712, if the content item is transmitted at 714. For example, at 726, the microprocessor 122 of the broadcast content reception device 104A stops streaming the content item based on the RF signal received at 702 to the content player device 106A. The method 700 then returns to 716 and the broadcast content reception device determines whether there is more channel content to be transmitted to the content player device.
At 728, the broadcast content reception device receives information that indicates a signal strength. For example, at 728, the microprocessor 122 of the broadcast content reception device 104A receives from the signal strength detection circuity of the receiver 132 information that indicates the signal strength of a signal input to the signal strength detection circuity. The method 700 then proceeds to 730.
At 730, the broadcast content reception device determines if the information that indicates the signal strength received at 728 indicates a signal strength value that is less than or equal to a threshold value. For example, at 710, the microprocessor 122 of the broadcast content reception device 104A determines if the information that indicates the signal strength received at 728 indicates a signal strength value that is less than or equal to -81 dBm. If the broadcast content reception device determines “YES” the information that indicates the signal strength received at 728 indicates a signal strength value that is less than or equal to the threshold value, the method 700 proceeds to 740. If the broadcast content reception device 104A determines “NO” the information that indicates the signal strength received at 728 does not indicate a signal strength value that is less than or equal to the threshold value, the method 700 proceeds to 732.
At 732, the broadcast content reception device determines whether channel content is to be transmitted to the content player device. If the broadcast content reception device determines that the channel content is to be transmitted to the content player device at 732, the method 700 then proceeds to 734. If the broadcast content reception device determines that the channel content is not to be transmitted to the content player device at 732, the method 700 then proceeds to 736.
For example, if the broadcast content reception device 104A determines that the information that identifies the channel received at 704 is accompanied by the predefined code (e.g., “00”) indicating that the channel content is to be transmitted to the content player device 106A without storing the channel content or the predefined code (e.g., “11”) indicating that the channel content is to be stored and transmitted to the content player device 106A, the broadcast content reception device 104A determines “YES” at 732. If the broadcast content reception device 104A determines that the information that identifies the channel received at 704 is accompanied by the predefined code (e.g., “01”) indicating that the channel content is to be stored without transmitting the channel content, the broadcast content reception device 104A determines “NO” at 732.
At 734, the broadcast content reception device transmits channel content based on the RF signal received at 702 to a content player device. For example, at 734, the microprocessor 122 of the broadcast content reception device 104A streams the channel content based on the RF signal received at 702 to the content player device 106A using the HLS protocol or the DASH protocol. The method 700 then proceeds to 736.
At 736, the broadcast content reception device stores the channel content based on the RF signal received at 702. For example, at 736, the microprocessor 122 of the broadcast content reception device 104A causes the broadcast content reception device 104A to operate as a DVR that stores the channel content in the memory 128 or an external hard drive coupled to the broadcast content reception device 104A via the I/O circuitry 130 of the broadcast content reception device 104A. The method 700 then proceeds to 738.
At 738, the broadcast content reception device determines whether there is more channel content to be stored by the broadcast content reception device. For example, at 738, the broadcast content reception device 104A determines whether all of a content item corresponding to the channel content has been stored by the broadcast content reception device by comparing a file size of the content item to an amount of data stored by the broadcast content reception device. If the broadcast content reception device determines “NO” there is not more channel content to be transmitted to the content player device, the method 700 ends. If the broadcast content reception device determines “YES” there is more channel content to be stored by the broadcast content reception device, the method returns to 728 and information is received that indicates the signal strength corresponding to the signal received from the antenna.
At 740, the broadcast content reception device transmits a request for channel information to the community server device 102. For example, at 740, the broadcast content reception device 104A transmits to the community server device 102 a request for channel information that includes the information that identifies the channel received at 704 and information the identifies a particular community of broadcast content reception devices. The method 700 then proceeds to 742.
At 742, the broadcast content reception device receives channel information from a community server device. For example, at 742, the broadcast content reception device 104A receives from the community server device 102 channel information including an IP address of the broadcast content reception device 104B (e.g., transmitted at 410 of the method 400 shown in
At 744, the broadcast content reception device determines if the channel information received at 742 indicates that content corresponding to the channel identified by the information that identifies the channel received at 704 is available from another broadcast content reception device in the community. If the broadcast content reception device determines “NO” the channel information received at 742 indicates that content is not available from another broadcast content reception device in the community, the method 700 returns to 732 and the broadcast content reception device determines whether channel content is to be transmitted to the content player device. If the broadcast content reception device determines “YES” the channel information received at 742 indicates that content is available from another broadcast content reception device in the community, the method 700 proceeds to 746.
At 746, the broadcast content reception device transmits a request for a channel content to another broadcast content reception device. For example, at 746, the broadcast content reception device 104A transmits a request for a channel content including the information that identifies the channel received at 704 to the broadcast content reception device 104B, using the IP address of the broadcast content reception device 104B included in the channel information received at 742 (e.g., transmitted at 410 of the method 400 shown in
At 748, the broadcast content reception device receives the channel content from the other broadcast content reception device. For example, at 748, the broadcast content reception device 104A receives the channel content from the broadcast content reception device 104B using the file transfer protocol (FTP), the HLS protocol, or the DASH protocol. The method 700 then proceeds to 750.
At 750, the broadcast content reception device determines whether channel content is to be transmitted to the content player device. If the broadcast content reception device determines “YES” the channel content is to be transmitted to the content player device at 750, the method 700 then proceeds to 752. If the broadcast content reception device determines “NO” the channel content is not to be transmitted to the content player device at 750, the method 700 then proceeds to 754.
At 752, the broadcast content reception device transmits the channel content received from the other broadcast content reception device at 748 to a content player device. For example, at 752, the microprocessor 122 of the broadcast content reception device 104A streams the channel content received from the broadcast content reception device 104B at 748 to the content player device 106A using the HLS protocol or the DASH protocol. The method 700 then proceeds to 754.
At 754, the broadcast content reception device stores the channel content received from the other broadcast content reception device at 748. For example, at 748, the broadcast content reception device 104A stores the channel content received from the other broadcast content reception device at 748 in the memory 128 or an external hard drive coupled to the broadcast content reception device 104A via the I/O circuitry 130 of the broadcast content reception device 104A. The method 700 then returns to 732 and the broadcast content reception device determines whether channel content is to be transmitted to the content player device.
At 802, a content player device transmits information that identifies a channel. For example, the content player device 106A transmits information that identifies a channel (e.g., channel number) via the WAN 108, which is accompanied by a predefined code (e.g., “00”) indicating that the channel content is to be transmitted to the content player device 106A without storing the channel content, a predefined code (e.g., “01”) indicating that the channel content is to be stored without transmitting the channel content or a predefined code (e.g., “11”) indicating that the channel content is to be stored and transmitted to the content player device 106A. The method 800 then proceeds to 804.
At 804, the content player device receives a message transmitted by a first broadcast content reception device. For example, at 804, the content player device 106A receives a message via the WAN 108 transmitted by the broadcast content reception device 104A, which includes information that identifies a particular channel and information that identifies a particular community of broadcast content reception devices. The method 800 then proceeds to 806.
At 806, the content player device transmits a request for channel information. For example, at 806, the content player device 106A transmits to the community server device 102 via the WAN 108 a request for channel information, which includes the information that identifies the channel and the information that identifies the community of broadcast content reception devices received at 804. The method 800 then proceeds to 808.
At 808, the content player device receives information that identifies a second broadcast content reception device. For example, the content player device 106A receives information that identifies the broadcast content reception device 104B (e.g., IP address of the broadcast content reception device 104B) from the community server device 102 via the WAN 108. The method 800 then proceeds to 810.
At 810, the content player device transmits a request for channel content to the second broadcast content reception device. For example, at 810, the content player device 106A transmits a request for channel content, which includes the information that identifies the channel received at 804, to the broadcast content reception device 104B via the WAN 108. The method 800 then proceeds to 812.
At 812, the content player device receives the channel content from the second broadcast content reception device. For example, at 810, the content player device 106A receives the channel content from the broadcast content reception device 104B via the WAN 108. The method 800 then proceeds to 814.
At 812, the content player device plays the channel content. For example, at 810, the microprocessor 140 of the content player device 106A causes the display device 150 to display the channel content received from the broadcast content reception device 104B, and also causes a speaker to emit sounds corresponding to the channel content. The method 800 then ends.
In the example of
The example of
Referring to the method 700 shown in
Assuming that the information that identifies Channel B received by the broadcast content reception device 104A at 704 of the method 700 is accompanied by the predefined code (e.g., “00”) indicating that the channel content is to be transmitted to the content player device 106A without storing the channel content, the broadcast content reception device 104A determines “NO” at 708 and the method 700 proceeds to 710. At 710, the broadcast content reception device 104A receives information that indicates a signal strength corresponding to the signal used to broadcast the Channel B content, wherein the signal strength is below a threshold value. Thus, the broadcast content reception device 104A determines “YES” the signal strength of the signal used to broadcast the Channel B is below the threshold value at 712 of the method 700.
