1 . A transmission apparatus comprising:
a control information generator for generating channel select control information indicative of configuration information for transmission, the configuration information comprising content included in a first video signal transmitted via a different transmission path than a second video signal; and
a multiplexer that multiplexes the second video signal and the channel select control information, the second video signal obtained based at least in part on a base video signal, the second video signal corresponding to the channel select control information.
2 . The apparatus of claim 1 , wherein the control information generator generates a first select control descriptor included in the channel select control information indicative of the configuration information, which is designated in the first video signal transmitted by a transmission scheme different from a transmission scheme of the second video signal.
3 . The apparatus of claim 1 , wherein the channel select control information generator generates a first select channel control descriptor in a program map table in the channel select control information, the first select channel control descriptor indicative of an elementary system designated in the first video signal transmitted by a transmission path different from a transmission path of the second video signal, and/or with a transport stream of a signal different from a transport stream of the second video signal.
4 . The apparatus of claim 3 , wherein the channel select control information generator generates information which designates 0x1FFF in an elementary packet ID field in the program map table in the channel select control information indicating that the elementary system of the second video signal is not designated, the second video signal transmitted by a single transmission path and with a single transport stream.
5 . The apparatus of claim 4 , wherein the channel select control information generator generates a second select channel control descriptor in the channel select control information indicative of association between the first video signal and the second video signal in a network information table.
6 . The apparatus of claim 4 , further comprising:
a resolution-enhanced signal generator configured to generate the second video signal based at least in part on inter-image prediction between the base video signal and a video signal different from the base video signal, and to output the second video signal to the multiplexer.
7 . A transceiver system comprising a transmission apparatus and a receiving apparatus,
wherein
the transmission apparatus comprises:
a first signal generator configured to receive a base video signal comprising configuration information constituting content, to convert the base video signal into a first video signal, and to output the first video signal;
a channel select control information generator configured to generate channel select control information indicative of configuration information for transmission, the configuration information of the first video signal transmitted via a different transmission path from a second video signal; and
a multiplexer configured to multiplex a second video signal and the channel select control information, the second video signal obtained based at least in part on a base video signal, corresponding to the channel select control information
the receiving apparatus comprises:
a first processor configured to input the first video signal, to convert the first video signal into a first display signal, and to output the first display signal;
a second processor configured to input the second video signal, to convert the second video signal into a second display signal, and to output the second display signal;
a channel select information processor configured to read the channel select control information in the second video signal, to generate channel select information indicative of a video image selected from the first video signal with reference to the configuration information, and to output the channel select information; and
a channel selector configured to input the channel select information, and to output the first and/or second display signals in accordance with the channel select information.
8 . The system of claim 7 , wherein the channel select control information generator generates a first select control descriptor included in the channel select control information indicative of the configuration information designated in the first video signal transmitted by a transmission scheme different from a transmission scheme of the second video signal.
9 . The system of claim 7 , wherein the channel select control information generator generates a first select channel control descriptor in a program map table in the channel select control information, the first select channel control descriptor indicative of an elementary system designated in the first video signal transmitted by transmission path different from a transmission path of the second video signal, and/or with a transport stream of a signal different from a transport stream of the second video signal.
10 . The system of claim 9 , wherein the channel select control information generator generates a second select channel control descriptor in the channel select control information indicative of association between the first video signal and the second video signal in a network information table.
11 . The system of claim 10 , wherein when detecting, in the channel select information, information indicative of existence of the second video signal corresponding to the first video signal, the channel selector excludes the first video signal from channel selection.
12 . The system of claim 10 , wherein when detecting, in the channel select information, information indicative of existence of the second video signal corresponding to the first video signal, the channel selector selects the second display signal when the first display signal is designated.
13 . The system of claim 10 , further comprising:
a resolution-enhanced signal generator configured to generate the second video signal based at least in part on inter-image prediction between the base video signal and a video signal different from the base video signal, and to output the second video signal to the multiplexer.
