- FIG. 2 illustrates an exemplary transition plan for transitioning to a NGBT service that is not backwards compatible with one or more existing terrestrial broadcast services.
- new equipment including hardware and/or software components
- FIG. 2 is described with respect to mobile devices, the transition plan is also applicable to fixed devices.
- consumer electronics manufacturers target the mobile devices by rolling out new mobile devices (e.g., cellular phones, smart phones, tablets, portable computers, etc.) with the newly developed hardware and/or software components (e.g., a receiver that can receive NGBT services).
- Mobile devices are targeted in step S 204 because consumers have a tendency to phase out mobile devices in a shorter amount of time (e.g., 2-3 years).
- any other consumer devices including fixed devices, (e.g., laptop computers, televisions, etc.) may be targeted by the consumer electronics manufacturers.
- the NGBT services are applied to a dedicated “transition” 6 MHz spectrum.
- any other spectrum size may be implemented, such as a spectrum that is a multiple of 6 MHz, based on spectrum availability.
- the NGBT services broadcast in the 6 MHz spectrum is a high-definition mobile service that is also receivable by fixed devices, with appropriate hardware/software.
- the transition broadcast channel is within the ultra high frequency (UHF) band in a range of 470 MHz to 698 MHz to offer better reception by mobile devices. In another embodiment, the transition broadcast channel is within a range of 470 MHz to 578 MHz based on possible reallocation of broadcast spectrum to wireless broadband services. In a further embodiment, the transition broadcast channel is placed adjacent to a channel used for another purpose (e.g., wireless broadband), or between a television broadcast channel and the channel used for another purpose, to reduce interference effects by, for example, broadcasting the NGBT services at a power lower than existing broadcast services.
- the transition broadcast channel may be a 6 MHz channel from 578 to 584 MHz (i.e., channel 32) or 698 to 704 MHz (i.e., channel 52).
- the transition broadcast channel is allocated within the very high frequency (VHF) band in a range of 54-88 MHz and/or 174-216 MHz.
- VHF very high frequency
- the VHF band is used for the transition broadcast channel to, for example, allow the broadcast providers to perform the hard switch in the UHF band, which allows for better signal penetration.
- step S 208 the NGBT services are fit into, and broadcast on, new Federal Communications Commission (FCC) re-packed freed frequencies.
- step S 208 requires requesting the FCC to save at least one broadcast channel in the repack for use as a transition broadcast channel.
- FCC Federal Communications Commission
- step S 210 the broadcast providers provide the NGBT and existing terrestrial broadcast services such as services according to the Advanced Television Systems Committee (ATSC) A/53 and A/153 standards, which are incorporated herein by reference.
- ATSC Advanced Television Systems Committee
- step S 212 the consumer electronics manufacturers start roll-out of fixed televisions with both ATSC A/53 and NGBT receivers for new services such as UHDTV.
- the fixed televisions are configured to determine whether NGBT or existing terrestrial broadcast services are being provided on a channel by channel basis.
- select broadcast providers start roll out of the NGBT services such as fixed and mobile services (e.g., UHDTV) on the original 6 MHz channels used to provide the existing television broadcast services.
- this roll out would be a hard switch determined by each individual broadcast provider. Time will be needed to allow market forces to work on the broadcast providers for the transition.
- step S 216 the market naturally phases out the ATSC A/53 receivers with new NGBT receivers as more service providers switch to NGBT services such as UHDTV.
- FIGS. 3A-3C illustrate an example of broadcast spectrum usage when transitioning to a NGBT service.
- the broadcast channels are consistent with the television broadcast channel allocation illustrated in FIG. 4 .
- the broadcast channels may or may not occupy a portion of the broadcast spectrum between 578 MHz and 698 MHz based on whether the FCC reallocates that frequency band for other uses such as wireless broadband.
- FIG. 3A illustrates an example of broadcast spectrum usage for existing digital television broadcast services according to ATSC A/53.
- the broadcast spectrum includes unused broadcast channels 310 and occupied broadcast channels 320 .
- the FCC is expected to reallocate portions of the existing broadcast spectrum available for existing television broadcast services for other purposes, such as broadband services. After this allocation (or repack), in a worst case scenario, no unused broadcast channels would be available in crowded markets.
- at least one broadcast channel is allocated as a transition broadcast channel 330 .
- the at least one transition broadcast channel 330 may be assigned by a government entity such as the FCC or determined by the individual television broadcasters.
- the at least one transition broadcast channel 330 may or may not have enough capacity to concurrently carry a first service from each of the broadcast providers in the same market.
- each of the at least one broadcast channel 330 has sufficient capacity to carry six different first services.
- each of the six different first services are provided by a different broadcast provider or the same broadcast provider may provide two or more of the six different services.
- other numbers of services may be provided on the transition broadcast channel 330 based on bit rate requirements.
- the at least one transition broadcast channel allows broadcast providers (e.g., broadcast providers 15 a, 15 b ) to provide the plurality of first and second services, concurrently, until the broadcast providers switch their own broadcasts to the plurality of first services.
- the broadcast providers include the same content in both the first and second services.
- the broadcast providers include higher resolution content in the plurality of first services.
- FIG. 3C illustrates an example where some of the broadcast providers have switched their own broadcast channels to broadcasting the plurality of first services (e.g., broadcast channel 340 ).
- first services e.g., broadcast channel 340
- transition broadcast channel space is freed up for use by other broadcast providers.
- transition broadcast channel access by each broadcast provider may be prioritized based on a lottery, auction, business agreement between the various broadcast providers, etc.
- FIG. 5 illustrates an example of a distribution system 500 used by the transition broadcast provider 10 to broadcast the plurality of first services in one embodiment.
- the distribution system 500 includes at least one receiver (e.g., receivers 510 a - 510 f, one for each first service) to receive the plurality of first services to be provided by the distribution system 500 .
- one of the receivers 510 a - 510 f may be configured to receive two or more of the first services from one or more of the broadcast providers.
- the receivers 510 a - 510 f receive the plurality of first services from at least two broadcast providers. In another embodiment, the receivers 510 a - 510 f receive the plurality of first services from at least one broadcast provider. The receivers 510 a - 510 f provide the received plurality of first services to a signal generator 520 . The signal generator 520 generates a broadcast signal with the plurality of first services and provides the broadcast signal to a transmitter 530 for broadcast to the reception apparatus 20 .
- the signal generator 520 is an OFDM-based signal generator as illustrated in FIG. 6 .
- an input formatter 610 receives the plurality of first services from the receivers 510 a - 510 f.

- The terms “a” or “an”, as used herein, are defined as one or more than one. The term “plurality”, as used herein, is defined as two or more than two. The term “another”, as used herein, is defined as at least a second or more. The terms “including” and/or “having”, as used herein, are defined as comprising (i.e., open language). The term “coupled”, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically. The term “program” or “computer program” or similar terms, as used herein, is defined as a sequence of instructions designed for execution on a computer system.

The term “non-transitory”, as used herein, is a limitation of the medium itself (i.e., tangible, not a signal) as opposed to a limitation on data storage persistency (e.g., RAM vs. ROM).
- The term “program”, as used herein, may also be used in a second context (the above definition being for the first context). In the second context, the term is used in the sense of a “television program”. In this context, the term is used to mean any coherent sequence of audio/video content such as those which would be interpreted as and reported in an electronic program guide (EPG) as a single television program, without regard for whether the content is a movie, sporting event, segment of a multi-part series, news broadcast, etc. The term may also be interpreted to encompass commercial spots and other program-like content which may not be reported as a program in an EPG.
- Reference throughout this document to “one embodiment”, “certain embodiments”, “an embodiment”, “an implementation”, “an example” or similar terms means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, the appearances of such phrases or in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments without limitation.
- The term “or” as used herein is to be interpreted as an inclusive or meaning any one or any combination. Therefore, “A, B or C” means “any of the following: A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.

FIG. 1 illustrates an exemplaryterrestrial broadcast system 2 for providing a plurality of first (e.g., NGBT) and second (e.g., existing broadcast) services. Theterrestrial broadcast system 2 includes atransition broadcast provider 10;broadcast providers 15 a, 15 b; areception apparatus 20; and aserver 40. AlthoughFIG. 1 illustrates onetransition broadcast provider 10; twobroadcast providers 15 a, 15 b; onereception apparatus 20; and oneserver 40, it should be understood that any number of each may be included in thebroadcast system 2. - The
transition broadcast provider 10 broadcasts a plurality of first services from a plurality ofdifferent broadcast providers 15 a, 15 b on a transition broadcast channel. The plurality ofdifferent broadcast providers 15 a, 15 b broadcast a plurality of second services on a plurality of different broadcast channels. For example, each of thetransition broadcast provider 10 and thebroadcast providers 15 a, 15 b broadcast respective services using a broadcast tower via a studio to transmitter link (STL). - In one embodiment, the first and second services provided by the
transition broadcast provider 10 andbroadcast providers 15 a, 15 b, respectively, are television broadcast services that include one or more television content, without regard to whether the content is a movie, sporting event, segment of a multi-part series, news broadcast, etc. Further, the first and second services may also include advertisements, infomercials, and other program-like content which may not be reported as a program in an EPG. - The plurality of first services are broadcast using a first transmission scheme such as orthogonal frequency-division multiplexing (OFDM) and the plurality of second services are broadcast using a second transmission scheme such as 8-level vestigial sideband modulation (8-VSB). However, any other combination of incompatible transmission schemes (i.e., not capable of simultaneous broadcast on the same broadcast channel) may be used to transmit the plurality of first and second services. In one embodiment, the
broadcast providers 15 a, 15 b broadcast digital television signals in accordance with standards set, for example, by the Advanced Television Systems Committee (ATSC) such as ATSC standard A/53, which is incorporated herein by reference in its entirety. - Further, although the
broadcast providers 15 a, 15 b and thetransition broadcast provider 10 are illustrated as each being associated with a separate broadcast tower, contractual agreements may be made between any two or more of thebroadcast providers 15 a, 15 b and thetransition broadcast provider 10. For example, broadcast provider 15 a may enter into a contractual agreement withbroadcast provider 15 b such that thebroadcast provider 15 b uses the same broadcast tower to provide its own at least one second service on its broadcast channel and the plurality of first services on the transition broadcast channel. - In one embodiment, the
transition broadcast provider 10 andbroadcast providers 15 a, 15 b provide the plurality of first and second services via terrestrial broadcasts. In the case of audio/video content, the content is compressed and broadcast using different transmission schemes, as discussed above. For example, the audio/video content of the plurality of first and second services is divided into a video elementary stream (ES) and an audio ES corresponding to the video and audio portions of the content. The video ES and audio ES are multiplexed with other data to form a broadcast multiplex, such as an MPEG-2 Transport Stream (TS), MPEG Media Transport (MMT) or similar technology in the case of the broadcast by thebroadcast providers 15 a, 15 b. Further, in one embodiment, the transition broadcast channel carries a transport (e.g., an MMT) or IP packets, which is different than that broadcast by thebroadcast providers 15 a, 15 b. - The
reception apparatus 20 is configured to receive the plurality of first services broadcast by thetransition broadcast provider 10. Thereception apparatus 20 may optionally be configured to receive the plurality of second services broadcast by thebroadcast provider 15 a, 15 b or services from other sources. The plurality of second services are also provided to consumer devices that are not configured to receive the plurality of first services (e.g., a television with a ATSC A/53 receiver). - The
reception apparatus 20 may be a mobile or fixed device. In one embodiment, thereception apparatus 20 is a mobile device such as a cellular phone, tablet, smart phone, portable computer, etc. due to the shorter upgrade cycles of these devices. However, fixed devices such as televisions and set top boxes may also be configured to receive the plurality of first services. - The
reception apparatus 20 is configured to connect to theInternet 30 via a wireless or fixed connection. For example, when thereception apparatus 20 is a mobile device, thereception apparatus 20 connects to theInternet 30 via a mobile data connection or Wi-Fi connection. When thereception apparatus 20 is a fixed device, thereception apparatus 20 connects via an Ethernet connection, wireless connection, mobile data connection, etc. - In one embodiment, the
reception apparatus 20 connects to theInternet 30 to receive or send information based on one of the plurality of first services broadcast by thetransition broadcast provider 10. For example, thereception apparatus 20 may make a purchase for advertised goods, contents, or services via theInternet 30, request additional information related to the one of the plurality of first services, interface to a social network website based on instructions accompanying the one of the plurality of first services, etc. Thereception apparatus 20, in one embodiment, receives the information associated with the one of the plurality of first services from at least oneserver 40. In other embodiments, theserver 40 may be provided by thetransition broadcast provider 10 or eachseparate broadcast provider 15 a, 15 b may provide itsown server 40. -
FIG. 2 illustrates an exemplary transition plan for transitioning to a NGBT service that is not backwards compatible with one or more existing terrestrial broadcast services. In step S202, new equipment, including hardware and/or software components, are developed for mobile devices. AlthoughFIG. 2 is described with respect to mobile devices, the transition plan is also applicable to fixed devices. In step S204, consumer electronics manufacturers target the mobile devices by rolling out new mobile devices (e.g., cellular phones, smart phones, tablets, portable computers, etc.) with the newly developed hardware and/or software components (e.g., a receiver that can receive NGBT services). Mobile devices are targeted in step S204 because consumers have a tendency to phase out mobile devices in a shorter amount of time (e.g., 2-3 years). However, any other consumer devices, including fixed devices, (e.g., laptop computers, televisions, etc.) may be targeted by the consumer electronics manufacturers. - In step S206, the NGBT services are applied to a dedicated “transition” 6 MHz spectrum. However, any other spectrum size may be implemented, such as a spectrum that is a multiple of 6 MHz, based on spectrum availability. In one embodiment, the NGBT services broadcast in the 6 MHz spectrum is a high-definition mobile service that is also receivable by fixed devices, with appropriate hardware/software.
- In one embodiment, the transition broadcast channel is within the ultra high frequency (UHF) band in a range of 470 MHz to 698 MHz to offer better reception by mobile devices. In another embodiment, the transition broadcast channel is within a range of 470 MHz to 578 MHz based on possible reallocation of broadcast spectrum to wireless broadband services. In a further embodiment, the transition broadcast channel is placed adjacent to a channel used for another purpose (e.g., wireless broadband), or between a television broadcast channel and the channel used for another purpose, to reduce interference effects by, for example, broadcasting the NGBT services at a power lower than existing broadcast services. For example, the transition broadcast channel may be a 6 MHz channel from 578 to 584 MHz (i.e., channel 32) or 698 to 704 MHz (i.e., channel 52).
- In other embodiments, the transition broadcast channel is allocated within the very high frequency (VHF) band in a range of 54-88 MHz and/or 174-216 MHz. The VHF band is used for the transition broadcast channel to, for example, allow the broadcast providers to perform the hard switch in the UHF band, which allows for better signal penetration.
- In step S208, the NGBT services are fit into, and broadcast on, new Federal Communications Commission (FCC) re-packed freed frequencies. In one embodiment, step S208 requires requesting the FCC to save at least one broadcast channel in the repack for use as a transition broadcast channel.
- In step S210, the broadcast providers provide the NGBT and existing terrestrial broadcast services such as services according to the Advanced Television Systems Committee (ATSC) A/53 and A/153 standards, which are incorporated herein by reference.
- Subsequently, in step S212, the consumer electronics manufacturers start roll-out of fixed televisions with both ATSC A/53 and NGBT receivers for new services such as UHDTV. The fixed televisions are configured to determine whether NGBT or existing terrestrial broadcast services are being provided on a channel by channel basis.
- In step S214, select broadcast providers start roll out of the NGBT services such as fixed and mobile services (e.g., UHDTV) on the original 6 MHz channels used to provide the existing television broadcast services. In one embodiment, this roll out would be a hard switch determined by each individual broadcast provider. Time will be needed to allow market forces to work on the broadcast providers for the transition.
- In step S216, the market naturally phases out the ATSC A/53 receivers with new NGBT receivers as more service providers switch to NGBT services such as UHDTV.
-
FIGS. 3A-3C illustrate an example of broadcast spectrum usage when transitioning to a NGBT service. In one embodiment, the broadcast channels are consistent with the television broadcast channel allocation illustrated inFIG. 4 . The broadcast channels may or may not occupy a portion of the broadcast spectrum between 578 MHz and 698 MHz based on whether the FCC reallocates that frequency band for other uses such as wireless broadband. -
FIG. 3A illustrates an example of broadcast spectrum usage for existing digital television broadcast services according to ATSC A/53. The broadcast spectrum includesunused broadcast channels 310 andoccupied broadcast channels 320. The FCC is expected to reallocate portions of the existing broadcast spectrum available for existing television broadcast services for other purposes, such as broadband services. After this allocation (or repack), in a worst case scenario, no unused broadcast channels would be available in crowded markets. Accordingly, in one embodiment, at least one broadcast channel is allocated as atransition broadcast channel 330. The at least onetransition broadcast channel 330 may be assigned by a government entity such as the FCC or determined by the individual television broadcasters. - The at least one
transition broadcast channel 330 may or may not have enough capacity to concurrently carry a first service from each of the broadcast providers in the same market. In one embodiment, each of the at least onebroadcast channel 330 has sufficient capacity to carry six different first services. Depending on the embodiment, each of the six different first services are provided by a different broadcast provider or the same broadcast provider may provide two or more of the six different services. However, other numbers of services may be provided on thetransition broadcast channel 330 based on bit rate requirements. - The at least one transition broadcast channel allows broadcast providers (e.g.,
broadcast providers 15 a, 15 b) to provide the plurality of first and second services, concurrently, until the broadcast providers switch their own broadcasts to the plurality of first services. In one embodiment, the broadcast providers include the same content in both the first and second services. In a further embodiment, the broadcast providers include higher resolution content in the plurality of first services. -
FIG. 3C illustrates an example where some of the broadcast providers have switched their own broadcast channels to broadcasting the plurality of first services (e.g., broadcast channel 340). As broadcast providers transition to broadcasting the plurality of first services, transition broadcast channel space is freed up for use by other broadcast providers. If necessary, transition broadcast channel access by each broadcast provider may be prioritized based on a lottery, auction, business agreement between the various broadcast providers, etc. -
FIG. 5 illustrates an example of adistribution system 500 used by thetransition broadcast provider 10 to broadcast the plurality of first services in one embodiment. Thedistribution system 500 includes at least one receiver (e.g., receivers 510 a-510 f, one for each first service) to receive the plurality of first services to be provided by thedistribution system 500. In other embodiments, one of the receivers 510 a-510 f may be configured to receive two or more of the first services from one or more of the broadcast providers. - The receivers 510 a-510 f receive the plurality of first services from at least two broadcast providers. In another embodiment, the receivers 510 a-510 f receive the plurality of first services from at least one broadcast provider. The receivers 510 a-510 f provide the received plurality of first services to a
signal generator 520. Thesignal generator 520 generates a broadcast signal with the plurality of first services and provides the broadcast signal to atransmitter 530 for broadcast to thereception apparatus 20. - In one embodiment, the
signal generator 520 is an OFDM-based signal generator as illustrated inFIG. 6 . As illustrated inFIG. 6 , aninput formatter 610 receives the plurality of first services from the receivers 510 a-510 f. Theinput formatter 610 formats the IP packets and/or transport streams associated with the plurality of received first services into packets of the same length for forward error correction (FEC). A codedmodulator 620 modulates the signal and astructure 630 performs framing output and signaling. Awaveform generator 640 subsequently performs an inverse fast fourier transfer (FFT) to generate the OFDM-based signal. - In one embodiment, a
controller 660 controls the operation of each of theinput formatter 610, codedmodulator 620,structure 630, andwaveform generator 640. Further, thecontroller 660 provides signaling information to thestructure 630. The signaling information includes, for example, FFT size (e.g., 1024, 4096, 8192, 32768, etc.), frame structure (i.e., how much data is in the frame), FEC structure (e.g., Low-density parity-check (LDPC) coding structure), modulation setting (e.g., 1024QAM, 256QAM), etc. Thecontroller 660 may be a dedicated controller for thesignal generator 520 or implemented by a controller of thereception apparatus 20. -
FIG. 7 illustrates an exemplary protocol stack for NGBT. In one embodiment, the physical layer is implemented using OFDM and LDPC code. However, other encoding and/or error correction modes may be utilized. Applications of the protocol stack include a video presentation, a social media interface, interactivity, ATSC 2.0, etc. For example, in one embodiment, the protocol stack provides a social media interface to share content on Facebook that is being watched on thereception apparatus 20. Broadcast content is sent via the user datagram protocol (UDP), which sends data one-way (no hand-shaking), and the social media interface is provided through the transmission control protocol (TCP) for hand-shaking acknowledgement of sent data, for example using Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH). MPEG DASH allows for dynamic control of service (video and audio) bit rate, which allows a smooth video to be maintained when networks are congested. - As illustrated in
FIG. 7 , the protocol stack includes a file delivery unidirectional transport (FLUTE) as defined in RFC 392 for delivering files in a transport, which is incorporated herein by reference in its entirety. The protocol stack further includes short-term key messages (STKMs) and long-term key messages (LTKMs) used as keys for encrypted content, the real-time transport protocol (RTP) which provides real-time transport of data, the real-time transport control protocol (RTCP) which provides out-of-band statistics and control information for an RTP flow, asynchronous layered coding (ALC) which allows for asynchronous stuffing of data into a datagram (e.g., UDP), high efficiency video coding (HEVC) for video and/or audio coding. The hypertext transfer protocol (HTTP) is used mainly in Internet access; the ATSC 2.0/Service Guides are table listings of content; captioning/subtitling are text fragments describing video content; and media codecs are HEVC, object-oriented audio coding, etc. to be used in either broadcast or broadband connections. Application is the presentation of data to the display device. -
FIG. 8 illustrates an embodiment of thereception apparatus 20. Thereception apparatus 20 is, or is integrated or an add-on component to, a mobile device such as a cellular phone, tablet, smart phone, portable computer, etc. In other embodiments, thereception apparatus 20 is a fixed device such as a digital television receiver device that is incorporated into a television set, a set top box, or any other fixed device configured to receive television content. - The
reception apparatus 20 includes atuner 802, which is configured to tune to different broadcast channels and receive the plurality of first services broadcast by thetransition broadcast provider 10 via a terrestrial broadcast. Thereception apparatus 20 is optionally configured to tune to and receive the plurality of second services broadcast by thebroadcast providers 15 a, 15 b. - In one embodiment, the
tuner 802 provides a broadcast signal received over a currently tuned broadcast channel to areceiver 806. Thereceiver 806 extracts audio and video (A/V) streams from a selected one of the plurality of first services. In one embodiment, thereceiver 806 is an OFDM-based receiver. However, thereceiver 806 may be configured to process other signal types such as an NGBT signal or other broadcast signal of a type different from the signal broadcast by thebroadcast providers 15 a, 15 b. The audio is decoded by anaudio decoder 810 and the video is decoded by avideo decoder 814. Further, uncompressed A/V data may be received via an uncompressed A/V interface (e.g., a HDMI interface). In one embodiment, the uncompressed A/V interface is only provided when thereception apparatus 20 is a fixed device. - The broadcast signal includes supplemental data such as one or a combination of closed caption data, EPG data, interactive content, ATSC 2.0 content, software applications, a social media interface, emergency services, accessibility data, etc. The supplemental data are separated out by the
receiver 806. However, the supplemental data may be received via theInternet 30 and anetwork interface 826. Thenetwork interface 826 includes one or a combination of wired and wireless interfaces (e.g., an Ethernet interface, cellular data network interface, etc.) Astorage unit 830 is provided to store non-real time or Internet-delivered content such as the supplemental data. - The
reception apparatus 20 generally operates under control of at least one processor, such asCPU 838, which is coupled to a workingmemory 840,program memory 842, and agraphics subsystem 844 via one or more buses (e.g., bus 850). TheCPU 838 receives closed caption data from thereceiver 806 as well as any other supplemental data used for rendering graphics, and passes appropriate instructions and data to thegraphics subsystem 844. The graphics outputted by thegraphics subsystem 844 are combined with video images by the compositor andvideo interface 860 to produce an output suitable for display on a video display. - Further, the
CPU 838 operates to carry out functions of thereception apparatus 20 including the processing of the supplemental data (e.g., interactivity, social media interfacing, etc.) and based on user inputs received from aninput interface 852. - Although not illustrated in
FIG. 8 , theCPU 838 may be coupled to any one or a combination of thereception apparatus 20 resources to centralize control of one or more functions. In one embodiment, theCPU 838 also operates to oversee control of thereception apparatus 20 including thetuner 802 and other television resources. -
FIG. 9 is a flow diagram of an exemplary broadcasting method. As illustrated inFIG. 9 , at least one receiver in a distribution system of thetransition broadcast provider 10 receives a plurality of first services from a plurality of different broadcast providers in step S902. The plurality of first services are provided to thetransition broadcast provider 10 via any one or a combination of communication means such as microwave transmissions (e.g., satellite or terrestrial), the Internet, a dedicated wired connection, cable television, shipping storage media containing the first service, etc. - In step S904, a broadcast signal including the plurality of first services is generated by a signal generator in the distribution system. In step S906, a transmitter broadcasts the plurality of services over a transition broadcast channel.
-
FIG. 10 is a flow diagram of an exemplary reception method. In step S1002, thereception apparatus 20 receives, via an input interface (e.g., a touch screen, remote control receiver, etc.) a selection of one of a plurality of first services broadcast via a transition broadcast channel. In step S1004, thereception apparatus 20 tunes to the transition broadcast channel. In step S1006, thereception apparatus 20 decodes the selected one of the plurality of first services on the tuned transition broadcast channel. In step S1008, thereception apparatus 20 outputs the selected one of the plurality of first services on the transition broadcast channel for display. -
FIG. 11 is a block diagram showing an example of a hardware configuration of acomputer 1100 that can be configured to function as, or incorporate, any one or a combination of the distribution system for thetransition broadcast provider 10; distribution system for thebroadcast providers 15 a, 15 b;reception apparatus 20; andserver 40. - As illustrated in
FIG. 11 , thecomputer 1100 includes a central processing unit (CPU) 1102, read only memory (ROM) 1104, and a random access memory (RAM) 1106 interconnected to each other via one ormore buses 1108. The one ormore buses 1108 are further connected with an input-output interface 1110.
