Playing a Videodisc

Some videodisc players can vary the playback speed of the CAV disc and also play the disc in reverse. Some players also can perform these operations on a CLV disc. Following are capability queries and the responses generated by a Pioneer 8000 device for CAV and CLV discs:

Query

Response
can reverse
TRUE
normal play rate
30 fps or 100%
fast play rate
90 fps or 300%
slow play rate
10 fps or 33.33%
maximum play rate
127 fps or 423.33%
minimum play rate
1 fps or 3.33%

Specifying a seek command before a play command can reduce the delay associated with a PLAY command.

A play command can specify a to and from position. If from is omitted, playing begins at the current position. If to is omitted, playing stops at the end of the disc, or at the beginning of the disc, if playing in reverse.

play video1 speed 30 fps

Note: Some videodisc players that cannot vary the playback speed return the same playback rate in response to these queries.
