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.
Claims16
A transmission method comprising:
- generating a frame for transfer which includes one or more first internet protocol (IP) packets and one or more second IP packets, the one or more first IP packets storing content which is audio or image data, and each of the one or more second IP packets including first reference clock information which indicates a time for playing back the content;
- and
- transmitting the generated frame through broadcasting including attaching, to each of the one or more first IP packets and each of the one or more second IP packets, an identifier indicating a preset value in accordance with a type of data stored in the one or more first IP packets or the one or more second IP packets,
- wherein the identifier attached to each of the one or more first IP packets indicates a first value corresponding to the content which is the audio or the image data, and the identifier attached to each of the one or more second IP packets indicates a second value corresponding to the first reference clock information, the second value being a fixed value.

A reception method comprising:
- receiving, through broadcasting, a frame for transfer which includes one or more first internet protocol (IP) packets and one or more second IP packets, the one or more first IP packets storing content which is audio or image data, and each of the one or more second IP packets including first reference clock information which indicates a time for playing back the content;
- determining whether each of the one or more IP packets that are received is the first IP packet or the second IP packet, and a type of data stored in the one or more first IP packets or the one or more second IP packets according to a preset value indicated in an identifier attached to each of the one or more first IP packets and each of the one or more second IP packets;
- and
- playing back the content stored in the one or more first IP packets, using the first reference clock information stored in the each of the one or more second IP packets, based on a result of the determination,
- wherein the identifier attached to each of the one or more first IP packets indicates a first value corresponding to the content which is the audio or the image data, and the identifier attached to each of the one or more second IP packets indicates a second value corresponding to the first reference clock information, the second value being a fixed value.
2 more elements
A transmission apparatus comprising:
- a non-transitory memory configured to store one or more programs;
- and
- a processor configured to execute the one or more programs and cause the transmission apparatus to operate as:
- a generator which generates a frame for transfer which includes one or more first internet protocol (IP) packets and one or more second IP packets, the one or more first IP packets storing content which is audio or image data, and each of the one or more second IP packets including first reference clock information which indicates a time for playing back the content;
- and
- a transmitter which transmits the generated frame through broadcasting including attaching, to each of the one or more first IP packets and each of the one or more second IP packets, an identifier indicating a preset value in accordance with a type of data stored in the one or more first IP packets or the one or more second IP packets,
- wherein the identifier attached to each of the one or more first IP packets indicates a first value corresponding to the content which is the audio or the image data, and the identifier attached to each of the one or more second IP packets indicates a second value corresponding to the first reference clock information, the second value being a fixed value.
4 more elements
A reception apparatus comprising:
- a non-transitory memory configured to store one or more programs;
- and
- a processor configured to execute the one or more programs and cause the reception apparatus to operate as:
- a receiver which receives, through broadcasting, a frame for transfer which includes one or more first internet protocol (IP) packets and one or more second IP packets, the one or more first IP packets storing content which is audio or image data, and each of the one or more second IP packets including first reference clock information which indicates a time for playing back the content;
- a determiner which determines whether each of the one or more IP packets that are received is the first IP packet or the second IP packet, and a type of data stored in the one or more first IP packets or the one or more second IP packets according to a preset fixed value indicated in an identifier attached to each of the one or more first IP packets and each of the one or more second IP packets;
- and
- a playback unit which plays back the content stored in the one or more first IP packets, using the first reference clock information stored in the each of the one or more second IP packets, based on a result of the determination,
- wherein the identifier attached to each of the one or more first IP packets indicates a first value corresponding to the content which is the audio or the image data, and the identifier attached to each of the one or more second IP packets indicates a second value corresponding to the first reference clock information, the second value being a fixed value.
