1. Field of the Disclosure
The present disclosure generally relates to multimedia content distribution networks and more particularly to providing users access to reports regarding popular multimedia content.
2. Description of the Related Art
Multimedia programs may be received over a multimedia content distribution network (MCDN). In traditional systems, users of the MCDN may not know which multimedia programs or channels are popular.
Television programs, video on-demand (VOD) movies, digital television content, music programming, and a variety of other types of multimedia content may be distributed to multiple users (e.g., subscribers) over various types of networks. Suitable types of networks that may be configured to support the provisioning of multimedia content services by a service provider include, as examples, telephony-based networks, coaxial-based networks, satellite-based networks, and the like.
In some networks including, for example, traditional coaxial-based “cable” networks, whether analog or digital, a service provider distributes a mixed signal that includes a large number of multimedia content channels (also referred to herein as “channels”), each occupying a different frequency band or frequency channel, through a coaxial cable, a fiber-optic cable, or a combination of the two. The bandwidth required to transport simultaneously a large number of multimedia channels may challenge the bandwidth capacity of cable-based networks. In these types of networks, a tuner within an STB, television, or other form of receiver is required to select a channel from the mixed signal for playing or recording. A user wishing to play or record multiple channels typically needs to have distinct tuners for each desired channel. This can be an inherent limitation of cable networks and other mixed signal networks.
In contrast to mixed signal networks, IPTV networks generally distribute content to a user only in response to a user request so that, at any given time, the number of content channels being provided to a user is relatively small, e.g., one channel for each operating television plus possibly one or two channels for simultaneous recording. As suggested by the name, IPTV networks typically employ IP and other open, mature, and pervasive networking technologies to distribute multimedia content. Instead of being associated with a particular frequency band, an IPTV television program, movie, or other form of multimedia content is a packet-based stream that corresponds to a particular network endpoint, e.g., an IP address and a transport layer port number. In these networks, the concept of a channel is inherently distinct from the frequency channels native to mixed signal networks. Moreover, whereas a mixed signal network requires a hardware intensive tuner for every channel to be played, IPTV channels can be “tuned” simply by transmitting to a server an indication of a network endpoint that is associated with the desired channel.
IPTV may be implemented, at least in part, over existing infrastructure including, for example, a proprietary network that may include existing telephone lines, possibly in combination with customer premises equipment (CPE) including, for example, a digital subscriber line (DSL) modem in communication with an STB, a display, a program rendering device, and other appropriate equipment to receive multimedia content and convert it into usable form. In some implementations, a core portion of an IPTV network is implemented with fiber optic cables while the so-called “last mile” may include conventional, unshielded, twisted-pair, copper cables.
IPTV networks support bidirectional (i.e., two-way) communication between a subscriber's CPE and a service provider's equipment. Bidirectional communication allows a service provider to deploy advanced features, such as VOD, pay-per-view (PPV), advanced programming information (e.g., sophisticated and customizable electronic programming guides (EPGs), and the like. Bidirectional networks may also enable a service provider to collect information related to a user's preferences, whether for purposes of providing preference based features to the user, providing potentially valuable information to service providers, or providing potentially lucrative information to content providers and others.
Disclosed embodiments provide a real time report of multimedia program or channels that are tuned into by other viewers. Such reports may suggest to the user that the channels or multimedia programs appearing on the report may be of interest.
In one aspect, a disclosed service provides reports of popular channels. The service includes determining a quantity of current viewers for each of a plurality of channels, ranking the plurality of channels according to the determined quantities, and populating a report with indications of the channels and their respective rankings. A user may provide input to select a channel or program from the report, and in response the service provides the user with multimedia content for the selected channel. The report may include, without limitation, for each multimedia program or channel, the following information: selectable icons, screen shots, moving video images, program titles, rankings, ratings, and genres.
In another aspect, a disclosed ranking server includes a tangible computer readable medium with instructions for assimilating data indicating a quantity of viewers viewing a channel, creating ranking data by ranking the quantity of viewers relative to further quantities of viewers tuned to other channels, and reporting the ranking data in response to a user selecting an information channel. The channels are provided by a an MCDN (e.g., Internet protocol television network). In some embodiments, a report includes channels or multimedia programs organized by genres, appropriateness, quality, and the time remaining in the current program. The report may include ranking data used for organizing channels or multimedia programs according to the quantity of viewers relative to further quantities of viewers of other channels or multimedia programs. A CPE device (e.g., an STB) may be used for monitoring channels or multimedia programs selected by users. Periodically or in response to a network request, data obtained from the monitoring may be reported to the MCDN. The data from multiple CPE devices may be organized, summarized, and delivered back to individual CPE devices in response to a user requesting a real-time report of most popular channels.
In still another aspect, a disclosed process provides a report of popular multimedia programs and includes providing data indicative of a local program selection to an MCDN, receiving from the MCDN a plurality of indications of programs ranked according to popularity, and providing indication of the popularity in the report. The report is provided on an information channel and may rank multimedia programs or channels according to quality, appropriateness, or remaining times. The report may include video images, titles, and other information that may be obtained from metadata for the multimedia programs or channels. Further, the report may include a pie chart or a bar chart that visually compares the popularity of a plurality of multimedia programs or channels.
Below, exemplary embodiments are described in sufficient detail to enable one of ordinary skill in the art to practice the disclosed subject matter without undue experimentation. It should be apparent to a person of ordinary skill that the disclosed examples are not exhaustive of all possible embodiments. Regarding reference numerals used to describe elements in the figures, a hyphenated form of a reference numeral may refer to a specific instance of an element and an un-hyphenated form of the reference numeral may refer to the element generically or collectively. Thus, for example, element 121-1 refers to an instance of an STB, which may be referred to collectively as STBs 121 and any one of which may be referred to generically as an STB 121.
Referring now to the drawings,
Client side 101 and server side 102 are linked by access network 130. In embodiments of MCDN 100 that leverage telephony hardware and infrastructure, access network 130 may include the “local loop” or “last mile,” which refers to the physical cables that connect a subscriber's home or business to a local exchange. In these embodiments, the physical layer of access network 130 may include both twisted pair copper cables and fiber optics cables. In a fiber to the curb (FTTC) access network, the “last mile” portion that employs copper is generally less than approximately 300 feet in length. In fiber to the home (FTTH) access networks, fiber optic cables extend all the way to the premises of the subscriber.
Access network 130 may include hardware and firmware to perform signal translation when access network 130 includes multiple types of physical media. For example, an access network that includes twisted-pair telephone lines to deliver multimedia content to consumers may utilize DSL. In embodiments of access network 130 that implement FTTC, a DSL access multiplexer (DSLAM) may be used within access network 130 to transfer signals containing multimedia content from optical fiber to copper wire for DSL delivery to consumers.
Access network 130 may transmit radio frequency (RF) signals over coaxial cables. In these embodiments, access network 130 may utilize quadrature amplitude modulation (QAM) equipment for downstream traffic. Also in these embodiments, access network 130 may receive upstream traffic from a consumer's location using quadrature phase shift keying (QPSK) modulated RF signals.
Services provided by the server side resources as shown in
A national VHO, for example, may deliver national content feeds to several regional VHOs, each of which may include its own acquisition resources to acquire local content, such as the local affiliate of a national network, and to inject local content such as advertising and public service announcements (e.g., emergency alert system messages) from local entities. The regional VHOs may then deliver the local and national content to users served by the regional VHO. The hierarchical arrangement of VHOs, in addition to facilitating localized or regionalized content provisioning, may conserve bandwidth by limiting the content that is transmitted over the core network and injecting regional content “downstream” from the core network.
Segments of private network 110, as shown in
As shown in
As shown in
In IPTV compliant implementations of MCDN 100, clients 120 are configured to receive packet-based multimedia streams from access network 130 and process the streams for presentation on program rendering devices 124. In addition, clients 120 are network-aware resources that may facilitate bidirectional-networked communications with server side 102 resources to support network hosted services and features. Because clients 120 are configured to process multimedia content streams while simultaneously supporting more traditional Web like communications, clients 120 may support or comply with a variety of different types of network protocols including streaming protocols such as real-time transport protocol (RTP) over user datagram protocol/Internet protocol (UDP/IP), as well as web protocols such as hypertext transport protocol (HTTP) over transport control protocol (TCP/IP).
The server side 102 of MCDN 100, as depicted in
Before distributing multimedia content to users, MCDN 100 first obtains multimedia content from content providers. To that end, acquisition resources 106 encompass various systems and devices to acquire multimedia content, reformat it when necessary, and process it for delivery to subscribers over private network 110 and access network 130.
Acquisition resources 106 may include, for example, systems for capturing analog and/or digital content feeds, either directly from a content provider or from a content aggregation facility. Content feeds transmitted via VHF/UHF broadcast signals may be captured by an antenna 141 and delivered to live acquisition server 140. Similarly, live acquisition server 140 may capture down-linked signals transmitted by a satellite 142 and received by a parabolic dish 144. In addition, live acquisition server 140 may acquire programming feeds transmitted via high-speed fiber feed 183 or other suitable transmission means. Acquisition resources 106 may further include signal conditioning systems and content preparation systems for encoding content.
As depicted in
After acquiring multimedia content, acquisition resources 106 may transmit acquired content over private network 110, for example, to one or more servers in content delivery resources 107. Live acquisition server 140 is communicatively coupled to an encoder which, prior to transmission, encodes acquired content using for example, Motion Picture Expert Group (MPEG) standards such as MPEG-2, MPEG-4, a Windows Media Video (WMV) family codec, or another suitable video codec.
Content delivery resources 107, as shown in
Content delivery server 155, in conjunction with live content server 156 and VOD delivery server 158, responds to user requests for content by providing the requested content to the user. The content delivery resources 107 are, in some embodiments, responsible for creating video streams that are suitable for transmission over private network 110 and/or access network 130. In some embodiments, creating video streams from the stored content generally includes generating data packets by encapsulating relatively small segments of the stored content according to the network communication protocol stack in use. These data packets are then transmitted across a network to a receiver (e.g., STB 121 of client 120), where the content is parsed from individual packets and re-assembled into multimedia content suitable for processing by a decoder.
User requests received by content delivery server 155 may include an indication of the content that is being requested. In some embodiments, this indication includes a network endpoint associated with the desired content. The network endpoint may include an IP address and a transport layer port number. For example, a particular local broadcast television station may be associated with a particular channel and the feed for that channel may be associated with a particular IP address and transport layer port number. When a user wishes to view the station, the user may interact with remote control device 126 to send a signal to STB 121 indicating a request for the particular channel. When STB 121 responds to the remote control signal, the STB 121 changes to the requested channel by transmitting a request that includes an indication of the network endpoint associated with the desired channel to content delivery server 155.
Content delivery server 155 may respond to such requests by making a streaming video or audio signal accessible to the user. Content delivery server 155 may employ a multicast protocol to deliver a single originating stream to multiple clients. When a new user requests the content associated with a multicast stream, there may be latency associated with updating the multicast information to reflect the new user as a part of the multicast group. To avoid exposing this undesirable latency to a user, content delivery server 155 may temporarily unicast a stream to the requesting user. When the user is ultimately enrolled in the multicast group, the unicast stream is terminated and the user receives the multicast stream. Multicasting desirably reduces bandwidth consumption by reducing the number of streams that must be transmitted over the access network 130 to clients 120.
As illustrated in
In some embodiments, client-facing switch 113 routes multimedia content encapsulated into IP packets over access network 130. For example, an MPEG-2 transport stream may be sent in which the transport stream consists of a series of 188-byte transport packets. In some embodiments, the MPEG-2 transport stream may include reports of popular channels or multimedia programs for a presentation on a user's program rendering device, in accordance with disclosed embodiments. Client-facing switch 113, as shown, is coupled to a content delivery server 155, acquisition switch 114, applications switch 117, a client gateway 153, and a terminal server 154 that is operable to provide terminal devices with a connection point to the private network 110. Client gateway 153 may provide subscriber access to private network 110 and the resources coupled thereto.
In some embodiments, STB 121 may access MCDN 100 using information received from client gateway 153. Subscriber devices may access client gateway 153, and client gateway 153 may then allow such devices to access private network 110 once the devices are authenticated or verified. Similarly, client gateway 153 may prevent unauthorized devices, such as hacker computers or stolen STBs, from accessing the private network 110. Accordingly, in some embodiments, when an STB 121 accesses MCDN 100, client gateway 153 verifies subscriber information by communicating with user store 172 via the private network 110. Client gateway 153 may verify billing information and subscriber status by communicating with an OSS/BSS gateway 167, which may translate a query to the OSS/BSS server 181. Upon client gateway 153 confirming subscriber and/or billing information, client gateway 153 may allow STB 121 access to IPTV content, VOD content, and other services. If client gateway 153 cannot verify subscriber information (i.e., user information) for STB 121, for example, because it is connected to an unauthorized local loop or RG, client gateway 153 may block transmissions to and from STB 121 beyond access network 130.
MCDN 100, as depicted, includes application resources 105, which communicate with private network 110 via application switch 117. Application resources 105, as shown, include application server 160 which is operable to host or otherwise facilitate one or more subscriber applications 165 that are made available to system subscribers. For example, subscriber applications 165, as shown, include EPG application 163. Subscriber applications 165 may include other applications as well. In addition to subscriber applications 165, application server 160 may host or provide a gateway to operation support systems and/or business support systems. In some embodiments, communication between application server 160 and the applications that it hosts and/or communication between application server 160 and client 120 may be via a conventional web based protocol stack such as HTTP over TCP/IP or HTTP over UDP/IP.
Application server 160 as shown also hosts an application referred to generically as user application 164. User application 164 represents an application that may deliver a value added feature to a user, who may be a subscriber to a service provided by MCDN 100. For example, in accordance with disclosed embodiments, user application 164 may be an application that monitors requests (e.g., channel selections or multimedia program selections) for multimedia content and provides reports of most popular multimedia programs or channels to users. User application 164, as illustrated in
As shown in
As shown in
As shown in
To contribute to the disclosed service, STB 121-2 may provide components of MCDN 100 (e.g., user application 164) with indications of currently selected channels. User application 164 may also receive indications from other STBs (e.g., STB 121-1) and CPE devices regarding content that is currently received by STBs or CPE devices. A report summarizing the most popular channels or multimedia programs may then be disseminated to the STBs or CPE devices over access network 130 or other communication channels.
The disclosed service may include receiving user input defining criteria for organizing indications of the channels or multimedia programs in the report. The criteria may be provided using remote control device 126 which, as shown, is communicatively coupled to STB 121. The user input may also be provided using a PC (not depicted) or other data processing system (e.g., smart phone) which may be communicatively coupled to STB 121. If necessary, STB 121 may relay the criteria through RG 122, over access network 130, and to any network-based component (e.g., user application 164) that needs the user defined criteria for reporting the popular channels or multimedia programs. User input that defines criteria for organizing the report may also be provided through a web portal accessed by STB 121, by a wireless telephony device (e.g., smart phone), or by a PC (not depicted) communicatively coupled to client 120 or one or more elements of server side 102.
Referring to
STB 121 as depicted in
Video and audio streams 238 and 236, as output from A/V decoder 230, may include audio or video information that is compressed, encrypted, or both. A/V decoder 230 may employ any video decoding algorithm including for example without limitation: H.263, H.264, any of the MPEG standards, or WMV standards including WMV 9. Similarly, decoder 230 may employ any audio decoding algorithm including for example without limitation: Dolby® Digital, Digital Theatre System (DTS) Coherent Acoustics, and Windows Media Audio (WMA). The video and audio streams 238 and 236, as shown in
As shown in
User settings 267 as shown includes user configurable parameters for organizing reports. For example, a user may set parameters that indicate that a report should include only channels or multimedia programs that contain certain content (e.g., content suitable for all audiences) or that are in a particular language (e.g., English). A report of the most popular channels or multimedia programs is stored as popularity report 217 and presented to the user, in some disclosed embodiments, by the user selecting an information channel (e.g., channel 100). The report is encoded in video stream 236 and/or audio stream 238 for presentation on program rendering device 124. The report contains indications (e.g., titles, icons, etc.) of multimedia programs or channels. In some cases, the report includes selectable icons associated with popular channels or multimedia programs that are available. In response to user selection of one of the icons, the corresponding channel or multimedia program is provided by STB 121 to the user (i.e., to program rendering device 124).
STB 121 contributes to popularity data and reports regarding local selections of channels and multimedia programs. Accordingly, STB 121 stores local selection data 223 and from time to time sends the data to a network element (e.g., a ranking server within an MCDN) over network interface 220. Local selection data 223 may be sent to the MCDN periodically, in response to a network request, according to a schedule, or otherwise as appropriate or necessary.
In addition to STB 121 contributing to popularity data that may be used by ranking servers and other STBs, STB 121 may update reports in real time in response to a change of popularity as evidenced by newly received popularity data. Accordingly, STB 121 may update in real-time received popularity data 282 and adjust popularity report 217 if necessary to provide timely and accurate popularity data. In some embodiments, updating a displayed popularity report is in response to a user request (e.g., received over remote control interface 237) to refresh the popularity report.
Reports may be displayed and organized according to user settings 267. For example, user settings 267 may specify that reports contain video images (e.g., streaming video) from programs. In addition, the report may include, according to user settings 267, a pie chart that compares the popularity of a number (e.g., ten) of channels. Alternatively, user settings 267 may specify that the report include a bar chart that illustrates the popularity of a number (e.g., ten) of channels.
In some emobiments, local selection data 223 only registers a program selection if minimum duration criteria are met. For example, data for a channel selection may only be stored into local selection data 223 and sent to a network ranking server if a viewer has been watching a channel for five minutes. Also, channel selection data stored within local selection data 223 and stored within ranking servers may be purged after its age reaches a configurable retention period. The retention period and the minimum duration criteria may be stored within user settings 267. The retention period and the minimum duration criteria may be preconfigured by developers of STB 121, may be provided with user input, or may be provided through administrator input.
In response to a user request to view a report, STB 121 encodes the report with video stream 238 and/or audio stream 236 for presentation by program rendering device 124. The displayed report includes indications (e.g., text, icons, video clips, screen shots, photographs, synthesized voice output, metadata, and avatars) of the most popular channels or multimedia programs.
As shown,
Ranking data 405 in report 401 is shown as a percentage of viewers watching the seven channels indicated in the report. Video images 407 may include still images, streaming video, program advertisement images, trademarks, and the like. Video images 407 and other elements within reports 401 and 421 may be selectable to allow a user request to receive the associated multimedia program or channel.
To the maximum extent allowed by law, the scope of the present disclosure is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited to the specific embodiments described in the foregoing detailed description.
