Availability of digital recording, and the copy control
for SAFIA
No descriptor
*1: This combination is not defined by TR-B15.
If, however, this combination is used to broadcast for some reason, TR-B15 specifies the output control
for the high-speed digital interface, video output, and audio output to restrict copying. Therefore, this
combination is handled as “Not recordable”.
*2: If the service type is digital TV service and emergency video service, and copy_control_type of the
digital copy control descriptor is 11, TR-B15 restricts the output via the high-speed digital interface,
video output, and audio output. Therefore, this combination is handled as “Not recordable”.
*3: The content is recorded by specifying Usage Pass Type = 1 (TV Recording), and Content Type = 0
(Audiovisual). For details of “Copy control not asserted” and “No more copy”, see Table B-2.17.
*4: APS in the copy control descriptor inherits the value of APS_control_data in the digital copy control
descriptor, or is set to 00 (APS is Off).
