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

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

Format

:

?A

Explanation

:

The P-Block Number Request command sent to a DVD disc groups

title numbers, chapter numbers and time code information together and returns the
data 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 does not provide the data.

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.
