640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.4 Host output | |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.4.1 General | When the TS Interface is configured in Sample Mode, and the Sample Track(s) are not TS, the TS sent by the Host to the CICAM shall only contain TS packets only with the following PIDs: • the comms PID; • 0x1FFF (NULL packets); • those declared in the sd_start() or sd_update() APDUs. The CICAM shall ignore NULL packets ... |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.4.2 Transmitting Samples | Before the transmission of a Sample, the Host shall announce that Sample by sending a Sample Start TS Packet (SSP) in the TS using the same PID as the Sample Track. A Host may repeat the SSP provided that the last repetition of the SSP precedes the start of the Sample. The SSP contains the credentials necessary for the... |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.4.3 Managing multiple Tracks | When more than one Track is declared, the Host shall not interleave Samples originating from different Tracks. The Host is required to send the complete Sample data of a Track before sending the next Sample of another Track. This restriction minimizes the buffering requirements of the CICAM and simplifies the send and ... |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.4.4 Track list update | The Host may update at any time the list of the pending Sample Tracks by sending an sd_update() APDU. If a Track is added, the Host shall not start sending Samples related to this additional Track until an affirmative sd_update_reply() is received from the CICAM. If a previously declared Track is removed, the Host shal... |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.5 TS packets | For a packet transferred from the Host to the CICAM and containing data from a Sample, the TS packet header bits shall be set as follows: • The sync byte shall be set to the LTS_id of the Local TS. • The transport_error_indicator shall be set to 0b0. • The payload_unit_start_indicator shall be set to 0b0. • The transpo... |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.6 CICAM output | The relative order of transport packets shall remain in the same order as sent by the Host, and shall follow the rules in clause 7.5.3.2 for setting the TS packet header fields. NOTE 1: The CICAM may regenerate the TS packet headers, hence the Host should not rely on them being identical when received back. After the r... |
640cdd88dcdf317f90107dbb72f1d840 | 103 205 | 7.5.3.7 ISOBMFF Samples | |
