Transmission device, transmission method of transmission stream, and processing device
First Claim
1. A transmission device, comprising:
- circuitry configured to, for each transmission packet of transmission packets successively disposed in a transmission stream;
determine whether each data packet that is encapsulated in a particular transmission packet has first identification information indicating that the data packet is to be handled with priority;
set second identification information in the particular transmission packet to a first value in a case that at least one data packet that is encapsulated in the particular transmission packet is determined to have the first identification information, the second identification information being disposed outside the data packet, and the first value of the second identification information indicating presence of the first identification information within the particular transmission packet; and
set the second identification information to a second value in a case that no data packet that is encapsulated in the particular transmission packet is determined to have the first identification information, the second value of the second identification information indicating absence of the first identification information within the particular transmission packet; and
a transmitter configured to transmit the transmission stream with the set second identification information.

Abstract
A response time until initial presentation decreases in such cases as reception of a service and reproduction of reception data after accumulation of the reception data.
Identification information based on which a packet handled with priority is identifiable is inserted into each of transmission packets at the time of transmission of a transmission stream containing the transmission packets disposed successively in the transmission stream. For example, each of the transmission packets is a multilayered packet containing a multiplexed transport packet in the uppermost layer. For example, the identification information is inserted into packets in a part or all of layers of each of the multilayered packets.

10. A transmission method for a transmission stream, the method comprising:
-
for each transmission packet of transmission packets successively disposed in the transmission stream, determining whether each data packet that is encapsulated in a particular transmission packet has first identification information indicating that the data packet is to be handled with priority, setting, by circuitry of a transmission device, second identification information in the particular transmission packet to a first value in a case that at least one data packet that is encapsulated in the particular transmission packet is determined to have the first identification information, the second identification information being disposed outside the data packet, and the first value of the second identification information indicating presence of the first identification information within the particular transmission packet, and setting, by the circuitry of the transmission device, the second identification information to a second value in a case that no data packet that is encapsulated in the particular transmission packet is determined to have the first identification information, the second value of the second identification information indicating absence of the first identification information within the particular transmission packet; and transmitting, by a transmitter of the transmission device, the transmission stream with the set second identification information.

11. A processing device, comprising:
-
circuitry configured to; acquire a transmission stream containing transmission packets successively disposed in the transmission stream; for each transmission packet of the transmission packets, determine whether each data packet that is encapsulated in a particular transmission packet has first identification information indicating that the data packet is to be handled with priority, set second identification information in the particular transmission racket to a first value in a case that at least one data packet that is encapsulated in the particular transmission packet is determined to have the first identification information, the second identification information being disposed outside the data packet, and the first value of the second identification information indicating presence of the first identification information within the particular transmission packet, and set the second identification information to a second value in a case that no data packet that is encapsulated in the particular transmission packet is determined to have the first identification information, the second value of the second identification information indicating absence of the first identification information within the particular transmission packet; and a transmitter configured to transmit the transmission stream with the set second identification information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
