Abstract
A transmission method includes: generating a frame for transfer which stores one or more first internet protocol (IP) packets storing content, and one or more second IP packets each including reference clock information which indicates a time for a playback of the content; and transmitting the generated frame through broadcasting. In the generating, header compression is performed on the one or more first IP packets and the header compression is not performed on the one or more second IP packets.
Claims2
A reception method comprising:
- receiving a transmission signal, the transmission signal including one or more transfer units that each include coded video content, first control information, and second control information;
- decoding the coded video content;
- and
- extracting clock information used for reproduction of the video content from at least one transfer unit among the one or more transfer units,
- wherein the first control information includes information used for the second control information, the second control information being provided for each of the one or more transfer units,
- wherein in the at least one transfer unit among the one or more transfer units, the second control information of the transfer unit contains the clock information used for reproduction of the video content,
- wherein the information indicating that the clock information is contained within a header of the transfer unit is stored in the first control information, and
- wherein the clock information is transmitted cyclically,
- wherein when the information indicates that the clock information is not contained within the header of the transfer unit, the second control information of the transfer unit does not contain the clock information.

A reception apparatus comprising:
- reception circuitry which, in operation, receives a transmission signal, the transmission signal including one or more transfer units that each include coded video content, first control information, and second control information;
- decoding circuitry which, in operation, decodes the coded video content;
- and
- extraction circuitry which, in operation, extracts clock information used for reproduction of the video content from at least one transfer unit among the one or more transfer units,
- wherein the first control information includes information used for the second control information, the second control information being provided for each of the one or more transfer units,
- wherein in the at least one transfer unit among the one or more transfer units, the second control information of the transfer unit contains the clock information used for reproduction of the video content,
- wherein the information indicating that the clock information is contained within a header of the transfer unit is stored in the first control information, and
- wherein the clock information is transmitted cyclically,
- wherein when the information indicates that the clock information is not contained within the header of the transfer unit, the second control information of the transfer unit does not contain the clock information.
