6.CURRENT PLAYER CONDITION REQUEST DESCRIPTIONS

6.1P-Block Number Request

Function

: The command returns information for the following groups:

 

DVD – Title Numbers, Chapter Numbers, Time

 

LB Compatible DVD (CAV) – Title Chapter, CAV Frame Numbers

 

LB Compatible DVD (CLV) – Title, Chapter, CLV Time

 

CD/VCD – Track Numbers, Index Numbers, Block Numbers, Time

Format

: ?A

Explanation : If the P-Block Number Request command is sent to a DVD disc, Title numbers, Chapter numbers and Time Code information are grouped together then the data is returned in a single report. When the command is sent to a LB-compatible DVD disc, the player returns Title numbers, Chapter numbers and CAV Frame numbers or CLV Time Codes. A request sent to a CD/VCD disc returns Track numbers, Index numbers, Block numbers and Time Codes.

The continuous Frame count information may be missing from a report if the P-Block Number Request is sent while the player is in normal playback mode. The player does not update Frame counts while processing this command. Rather than returning an incorrect Frame count, the player ignores the request.

If the player is in Random Access Mode or is reading the lead-in/lead out area of the disc, the report contains correct values.
