Abstract: In a converting method relating to picture luminance according to one aspect of the present disclosure, the picture luminance is formed by luminance values in a first luminance range. In this method, a first luminance signal that indicates code values obtained by quantizing the luminance value of the picture is obtained, code values, which are associated with the code values indicated by the obtained first luminance signal by quantization for a second luminance range different in a maximum value from the first luminance range are determined as converted code values, and the first luminance signal is converted into a second luminance signal indicating the converted code values. As a result, the converting method is further improved.

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 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.
