Abstract: A transmitting device includes: a generator that generates an encoded stream by using rate control satisfying a determined definition of a receiving buffer model; and a transmitter that sequentially transmits a transmitting packet, and the receiving buffer model includes a first buffer that converts a packet into a first packet where the packet includes a packet header of a variable length, and the first packet includes a packet header of a fixed length of a decompressed header, a second buffer that converts the first packet into a second packet including a payload of a variable length, a third buffer that converts the second packet into a Network Abstraction Layer (NAL) unit, and a fourth buffer that outputs an access unit generated from a plurality of sequentially accumulated NAL units to a decoder at a timing of a decoding time corresponding to the access unit.

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.

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.
