CURRENT PLAYER CONDITION REQUEST DESCRIPTIONS

6.1

P-Block Number Request

Function
Format
Explanation :
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.
