The Emergency Alert System is a national public warning system that stems from the desire of the President of the United States to communicate with the public in times of national emergencies. In the early 1960s, the chief executive began allowing local and state authorities to use the system to transmit localized warnings, such as, but not limited to, child abduction emergencies (AMBER alerts) and weather information. The system has been designed to deliver messages quickly and automatically in the event of an emergency. Among its most conspicuous features to the public may be the automatic interruption of broadcast programming that replaces program audio with an aural alert and superimposes a text crawl with warning information at the bottom of the TV screen. In some situations, a local news broadcasting station may completely preempt a regularly scheduled program.
Embodiments of the disclosed invention include a system and a method for bypassing an emergency alert break-in for a recorded event. For example, in one embodiment, a method is disclosed that includes receiving media content data from a cable service provider. The method determines a recording setting associated with the set top box and determines whether the media content data includes an emergency alert break-in on a channel associated with the recording setting. In one embodiment, in response to a determination that the media content data includes an emergency alert break-in on a channel associated with the recording setting, the method bypasses recording of the emergency alert break-in on the channel associated with the recording setting.
In accordance with another embodiment, a set top box is disclosed for bypassing an emergency alert break-in for a recorded event. In one embodiment, the set top box includes a memory component for storing computer executable instructions; a communication interface for receiving media content data from a cable service provider; a decoder module for decoding the received media content data; an emergency alert break-in monitoring module for identifying an emergency alert break-in from the received data; a digital video recorder controller module for determining whether the identified emergency alert break-in affects a recording of a program on a recorded channel; and an emergency alert break-in bypass module for bypassing the identified emergency alert break-in for enabling the digital video recorder controller module to record the program without the identified emergency alert break-in.
Illustrative embodiments of the present invention are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein and wherein:
The disclosed embodiments and advantages thereof are best understood by referring to
The disclosed embodiments recognize deficiencies associated with the current emergency alert system. For example, the disclosed embodiments recognize that, in most situations, a viewer prefers that the recording of a regularly scheduled program not be interrupted by a local news break-in and/or by an emergency alert system message. For instance, in many situations, a regularly scheduled program is recorded and not viewed until several days later. Accordingly, a recording of an emergency alert break-in occurring several days ago is of little significance to the viewer. In these situations, the viewer prefers that the regularly scheduled program had been recorded. Accordingly, the disclosed embodiments provide a system and method for bypassing an emergency alert break-in for a recorded event. As referenced herein, the term “bypass” and/or “bypassing” means to circumvent recording of an emergency alert break-in. In addition, as referenced herein, an emergency alert break-in means any message, alert, and/or newscast that interrupts by preempting (e.g., a local news break-in) and/or modifying displaying of a regularly scheduled program (e.g., adding an emergency alert system message crawling text at the bottom of the screen) to present information associated with an urgent and/or important event.
One or more cable/satellite head ends, such as, but not limited to, cable head end 104, receives the emergency alert system signal from emergency alert system issuing authority 102 and/or from a neighboring broadcasting station relaying the emergency alert system message. Cable head end 104 is a facility that originates and communicates cable/satellite TV services to a plurality of subscribers, such as, but not limited to, residential location 128 via cable network 110. In addition, in one embodiment, cable head end 104 may also receive upstream requests, such as, but not limited to, receiving a video on demand request, from residential location 128 via cable network 110. In some embodiments, cable network 110 may include, but is not limited to, one or more coaxial cable networks, fiber-optic networks, and/or satellite networks. Additionally, in some embodiments, cable network 110 may also include twisted pair networks for providing IPTV cable television-type services.
In one embodiment, cable head end 104 includes an emergency alert system encoder/decoder (endec) 105 for receiving and decoding an emergency alert system signal. In one embodiment, emergency alert system encoder/decoder 105 decodes an emergency alert system signal to determine the emergency type and affected areas associated with the emergency alert system signal. For example, an emergency alert system signal contains codes that identify the key elements of an emergency alert system message, such as, but not limited to, the message originator, the event, the location of the event, and the valid time period of the message.
In some embodiments, emergency alert system encoder/decoder 105 passes the decoded emergency alert system message to a media server 106. In one embodiment, media server 106 includes computer executable instructions and/or electronic components that automatically recognize incoming EAS information and generates the appropriate emergency text crawl and/or other appropriate display information associated with the emergency alert system message for overlaying the emergency alert system message over a television program.
In some embodiments, cable head end 104 utilizing media server 106 and/or other appropriate device encodes a plurality of television programming signals from a variety of input sources, such as, but not limited to, one or more local broadcasting stations 122, cable/satellite programming sources 124, and stored media library 126. Additionally, in some embodiments, cable head end 104 receives signals broadcasted from local broadcasting stations 122 over the air using cell transmission towers. In one embodiment, cable head end 104 may encode one or more television signals, such as, but not limited to, signals received from local broadcasting stations 122, with an emergency alert system message in response to receiving an emergency alert system message originating from emergency alert system issuing authority 102.
In some embodiments, cable head end 104 may include a cable modem termination system (CMTS), such as, CMTS 107, for providing high-speed Internet access via a cable modem to subscribers. In one embodiment, CMTS 107 sends and receives digital cable modem signals on cable network 110, such as, but not limited to, receiving signals sent upstream from a subscriber's cable modem, such as, cable modem 114. In some embodiments, CMTS 107 converts the signals into IP packets and routs the signals to an Internet Service Provider for connection to Internet 120. Internet 120 is a massive network of networks that connects millions of computers/electronic devices together globally, forming a network in which any computer/electronic device can communicate with any other computer/electronic device as long as they are both connected to the Internet 120. In addition, in some embodiments, CMTS 107 may also send signals downstream to cable modem 114. In one embodiment, cable modem 114 may be hardwired to set top box 130 for communicating data between set top box 130 and cable modem 114. In some embodiments, cable modem 114 may include a wireless transceiver for communicating data wirelessly to one or more electronic device, such as, but not limited to, set top box 130.
In accordance with one embodiment of the disclosed invention, a cable/satellite programming provider may provide, as a premium service, or as a free service to their subscribers the ability to bypass an emergency alert break-in for a recorded event. For instance, as will be further described, in one embodiment cable head end 104 may encode and transmit a set of regularly scheduled programs (e.g., local channels) over a first set of channels that may include an emergency alert break-in and may also encode and transmit the set of regularly scheduled programs on a second set of channels that does not include any emergency alert break-in, hereinafter, referred to as a non-emergency alert break-in channel. In some embodiments, the non-emergency alert break-in channel may only be decoded by a digital video recorder for recording the regularly scheduled program. In other words, in some embodiments, a viewer may not elect to bypass viewing of an emergency alert break-in on a live broadcasting channel. In one embodiment, in response to identifying an emergency alert break-in on a channel associated with a recording setting of set top box 130, set top box 130 determines whether the channel associated with the recording setting has a corresponding non-emergency alert break-in channel. In these embodiments, set top box 130 may modify the recording setting to record a regularly scheduled program from the non-emergency alert break-in channel.
In accordance with another embodiment, set top box 130 may only transmit the first set of channels that may include an emergency alert break-in. In these embodiments, in response to identifying an emergency alert break-in on a channel associated with a recording setting of set top, box 130, set top box 130 may request the regularly scheduled program associated with the recorded channel from a cable service provider (e.g., using similar technology to video on demand). In response to receiving the regularly scheduled program, set top box 130 may modify the recording setting to record the received regularly scheduled program.
In addition, in some embodiments, set top box 130 may request the regularly scheduled program from an Internet television source, such as, but not limited to, a website providing live and/or recorded television programming. For example, in some embodiments, set top box 130 may attempt to retrieve the regularly scheduled program from a website associated with a network broadcasting the regularly scheduled program, such as, but not limited to, ABC.com™. For instance, ABC.com™ currently provides aired episodes of some of their regularly scheduled programs. Thus; in some embodiments, set top box 130 may request the regularly scheduled program associated with a recorded event that was interrupted by an emergency alert break-in after the regularly scheduled program has terminated/aired. In these embodiments, set-top box 130 may modify the recording setting to store the received regularly scheduled program for enabling the viewer to playback the regularly scheduled program at a desired time. For example, in some embodiments, set top box 130 may record the streaming data of the regularly scheduled program and store the recorded data. In other embodiments, set top box 130 may download the regularly scheduled program and associate the downloaded file with the corresponding recording setting.
Processing unit 200 may comprise of one or more microprocessors for executing computer usable program code/instructions for providing television programming and for bypassing an emergency alert break-in for a recorded event. For example, in one embodiment, processing unit 200 executes computer executable instructions 220 stored in memory component 204 for identifying an emergency alert break-in signal and modifying a recording setting to record a non-emergency alert break-in channel.
In some embodiments, memory component 204 is a volatile memory component of set top box 130. Volatile memory is memory that loses its contents when set top box 130 loses power. For example, in some embodiments, memory component 204 may be random access memory (RAM). Random access memory stores currently executing instructions and/or data utilized by an operating system, software program, hardware device, and/or a user.
Data storage unit 206 is a non-volatile memory component of set top box 130, such as, but not limited to, a hard disk drive. Non-volatile memory retains stored data when power is loss. In some embodiments, data storage unit 206 may be an external hard drive and/or a network data storage unit. In some embodiments, data storage unit 206 may store media content files 222, such as, but not limited to, television content received from cable head end 104. In addition, in accordance with one embodiment, data storage unit 206 may store a data structure 224, such as, but not limited to, a data table that includes a list of non-emergency alert break-in channels corresponding to a plurality of regularly scheduled broadcasting channels. Additionally, in some embodiments, data storage unit 206 may store a set of user preferences 230 associated with the recording of one or more television programs. For example, in some embodiments, a user may modify user preferences 230 to specify whether a recording event should bypass an emergency alert break-in. In some embodiments, a user may specify for each individual recording event whether to bypass an emergency alert break-in. In other embodiments, a user may specify to bypass an emergency alert break-in for all recording events.
In accordance with the disclosed embodiments, set top box 130 includes communication interfaces 216 for receiving media content signals/data from, but not limited to, cable head end 104. In addition, in some embodiments, communication interfaces 216 may provide connection ports for coupling set top box 130 to one or more electronic devices. For example, in one embodiment, communication interfaces 216 includes a video output interface, such as, but not limited to, a coaxial cable connection for coupling set top box 130 to display unit 150 (as depicted in
Set top box 130 may also include one or more decoder module 214 for decoding received media content signals, such as, but not limited to, cable television signals received from cable head end 104. For example, in some embodiments, decoder module 214 may be a quadrature amplitude modulation (QAM) tuner. Quadrature amplitude modulation is one format by which digital media content channels are encoded and transmitted by a cable company, such as, cable head end 104. A QAM tuner is an electronic tuning device used in digital television sets, set top boxes, DVRs, and other electronic equipment to tune/decode the received media content channels. In some embodiments, decoder module 214 may also be an Advanced Television Systems Committee (ATSC) tuner/receiver for receiving and decoding over the air digital channels.
In accordance with one embodiment, set top box 130 may include an emergency alert break-in (EAB) monitoring module 218 for identifying/detecting an emergency alert break-in signal. For example, all emergency alert system messages are required to be digitally encoded with a header, an attention signal, an audio announcement, and a digitally encoded end-of-message marker The header includes information about who originated the alert (the President, state or local authorities, the National Weather Service, or the broadcaster), a short, general description of the event (tornado, flood, severe thunderstorm), the counties or states affected, the expected duration of the event (in minutes), the date and time it was issued, and an identification of the originating station. The attention signal follows the header and may last between 8 to 25 seconds, depending on the originating station. For example, in some embodiments, commercial broadcasting stations, such as local broadcasting stations 122, may broadcast an attention signal consisting of a “two tone” combination of 853 Hz and 960 Hz sine waves. The emergency alert system message ends with three bursts of an end of message indicator, which is the text NNNN, preceded each time by the binary 10101011.
In one embodiment, emergency alert break-in monitoring module 218 may identify an emergency alert break-in signal transmitted from cable head end 104 by recognizing the header information and/or the attention signal associated with an emergency alert system message encoded in one or more broadcast channels. In some embodiments, emergency alert system monitoring module 218 may be a dedicated tuner for monitoring a particular channel associated with a recording event for identifying an emergency alert break-in.
In addition, in some embodiments, set top box 130 may include an emergency alert break-in bypass module 228 for bypassing an emergency alert break-in for a recorded event. As will be further described, in some embodiments, bypass module 228 may retrieve user preferences 230 associated with a recording event to determine whether to bypass recording of an emergency alert break-in on the channel associated with the recording event. In some embodiments, bypass module 228 may identify a non-emergency alert break-in channel associated with the recording event and modify a recording setting to record the non-emergency alert break-in channel for the recording event. In other embodiments, bypass recording module 228 may request a regularly scheduled program corresponding to the recording event from a cable service provider and/or an Internet television source and modify the recording setting to record the received regularly scheduled program.
Additionally, set top box 130 may include a digital video recorder (DVR) controller 226 for recording and playback of media content files 222. In some embodiments, DVR controller 226 may be utilized to record and/or playback streaming video received from an Internet source. In some embodiments, DVR controller 226 may encompass one or more functions and/or features performed by bypass module 228 and/or emergency alert break-in monitoring module 218 as described above.
In one embodiment, set top box 130 may include wireless transceiver 208 for providing short-range exchange of data using, but not limited to, infrared light. For example, in one embodiment, wireless transceiver 208 enables a viewer to utilize a remote control device to configure and operate set top box 130, such as, but not limited to, configuring set top box 130 to record an event/program. Additionally, in some embodiments, wireless transceiver 208 may utilize a wireless Internet protocol for communicating data wirelessly to cable modem 114. For example, in one embodiment, wireless transceiver 208 may receive streaming media content from an Internet source via a cable modem 114.
In some embodiments, set top box 130 may include a cable card interface 210 for interfacing with a plug-in cable/smart card that enables viewing and/or recording of cable television programming. For example, in some embodiments, cable card 210 comprises instructions and/or a decryption key for decoding encrypted cable television signals transmitted by cable head end 104.
Additionally, set top box 130 may include a power source, such as, power unit 202. In one embodiment, power unit 202 converts the input power from an AC adaptor to run various components of set top box 130. In addition, in some embodiments, power unit 202 may include an internal power source, such as, but not limited to, a battery component.
With reference now to
For example, in the depicted embodiment, set top box 130 utilizing decoder module 214 decodes one or more of the received channels to produce video/audio content. In one embodiment, decoder module 214 communicates with DVR controller 226 to determine a recording setting. For example, in the depicted embodiment, DVR controller 226 is set to record channel 4 (local channel B). In the depicted embodiment, decoder module 214 decodes local channel B and passes the signal to emergency alert break-in monitoring module 218 for determining whether local channel B is encoded with an emergency alert break-in. In some embodiments, emergency alert break-in monitoring module 218 may include a separate tuner/decoder for decoding the recorded channel. In one embodiment, emergency alert break-in monitoring module 218 identifies an emergency alert break-in by monitoring for the header information and/or an attention signal associated with an emergency alert system message. In the depicted embodiment, in response to detecting an emergency alert break-in on the recorded channel, emergency alert break-in monitoring module 218 passes the information to emergency alert break-in bypass module 228. In one embodiment, emergency alert break-in bypass module 228 retrieves data structure 224 for identifying a corresponding non-emergency alert break-in channel associated with local channel B. In some embodiments, emergency alert break-in bypass module 228 may also retrieve user preferences 230 to determine whether to bypass an emergency alert break-in for the recorded event. In one embodiment, in response to a determination to bypass the emergency alert break-in for the recorded event, emergency alert break-in bypass module 228 modifies the recording setting of DVR controller 226 to record non-emergency alert break-in channel 901 corresponding to local channel B.
With reference now to
However, if the process determines that the digital video recorder is set to record a recording event, the process determines the recording channel associated with the recording event at step 408. At step 410, the process decodes the television signal associated with the recording channel of the recording event. The process, at step 412, determines whether the decoded television signal associated with the recording channel includes an emergency alert break-in. If the process determines that the television signal associated with the recording channel does not include an emergency alert break-in, the process records the recording channel at step 414, with process 400 terminating thereafter.
If the process, at step 412, determines that the television signal associated with the recording channel does include an emergency alert break-in, the process retrieves the user preferences associated with the recording event. At step 418, the process determines whether to bypass recording of the emergency alert break-in for the recording event based on the retrieved user preferences. If for some reason, a user elects not to bypass recording of an emergency alert break-in for the recording event, the process records the recording channel at step 414, with process 400 terminating thereafter.
However, if the process, at step 418, determines to bypass an emergency alert break-in for a recording event based on the retrieved user preferences, the process bypasses the emergency alert break-in and records the regularly scheduled program associated with the recording channel. For example, in one embodiment, the process, at step 420, may determine a non-emergency alert break-in channel associated with the recording channel. At step 422, the process modifies the recording setting to record from the non-emergency alert break-in channel, with process 400 terminating thereafter.
In accordance with another embodiment, responsive to a determination to bypass an emergency alert break-in for a recording event, the process, at step 424, may transmit a request to a cable service provider for the regularly scheduled program associated with the recording event. In response to receiving the regularly scheduled program from the cable service provider, the process, at step 426, modifies the recording setting to record the received regularly scheduled program in lieu of recording the recording channel, with process 400 terminating thereafter.
In addition, in accordance with some embodiments, responsive to a determination to bypass an emergency alert break-in for a recording event, the process, at step 428, may request the regularly scheduled program from an Internet source. For example, currently, several websites enables live viewing of local broadcast channels via the Internet. In addition, several broadcasting networks maintain websites that enable viewing of aired episodes associated with their regularly scheduled programs. In one embodiment, a user may configure set top box 130 to retrieve the regularly scheduled program from a particular website. In addition, in some embodiments, set top box 130 may be configured to automatically query an Internet source for the desired regularly scheduled program. In other embodiments, a user may manually query and retrieve the regularly scheduled program from the Internet source using set-top box 130.
In response to receiving the regularly scheduled program from the Internet source, the process modifies the recording setting to store the retrieved regularly scheduled program at step 430, with process 400 terminating thereafter. In some embodiments, the process may record the streaming video retrieved from an Internet source. In other embodiments, the process may download a media content file associated with a regularly scheduled programming and associated the downloaded media content file with the recorded event.
