Abstract: A transmitting method includes: inputting, per unit time, a plurality of transfer packets less than or equal to a predetermined number; and transmitting, per the unit time, the plurality of transfer packets that have been input, in a state where definitions compliant with a receiving buffer model are satisfied. Each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload. The definitions compliant with the receiving buffer model are predetermined for guaranteeing a buffering operation of a receiving device, and specify converting a first packet into a second packet and outputting the second packet from a buffer of the receiving device at a predetermined extraction rate. The first packet is included in the transfer packets received and includes a variable-length packet header and a variable-length payload. The second packet has a fixed-length packet header that is extended.

Abstract: A transmission method according to one aspect of the present disclosure is a transmission method for transmitting content through broadcasting, including: generating a plurality of frames for transfer, each of which includes a plurality of first transfer units in which the content is to be stored, each of the plurality of frames having a fixed length, each of the plurality of first transfer units having a variable length; and transmitting the plurality of frames generated. The generating includes sequentially placing the plurality of first transfer units into the plurality of frames, and in the placing, even when a data size of a current first transfer unit to be processed is smaller than a remaining capacity of a current frame to be processed, the current first transfer unit is placed into a next frame.

Abstract: A video transmission method according to the present disclosure includes: generating a transmission signal including, in a time series, first video data having a first luminance dynamic range and second video data having a second luminance dynamic range wider than the first luminance dynamic range; and transmitting the transmission signal generated. In the generating of the transmission signal, a signal level corresponding to a luminance value is limited to a value lower than a limit value that is predetermined, in a transition period provided for switching from one of the first video data and the second video data to the other.

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.

Abstract: A reception apparatus including a decoding apparatus and a demultiplexing apparatus for identifying a packet with clock information. The decoding apparatus receives a transfer frame, which includes one or more first transfer units obtained by multiplexing contents. A decoder in the decoding apparatus acquires the first transfer units by decoding the transfer frame, and outputs the first transfer units to the demultiplexing apparatus. The demultiplexing apparatus acquires content by demultiplexing the first transfer units. Additionally, a heading first transfer unit, which is positioned at a head within the transfer frame, contains reference clock information. The decoder generates information for identifying the heading first transfer unit and outputs the information to the demultiplexing apparatus.
