CLD-V5000 Level III • Chapter Three

5) PLAY

LD/CD

Function:

Pictures and sound are played back.

Format:

(Address) P L

Explanation:

1) If this command is sent when the player is in Random Access

 

Mode, video and audio are played at normal speed. Play Mode is

 

the only mode in which sound is automatically reproduced with

 

video on LaserDiscs.

 

2) If an address is specified, the player will play to that address

 

and stop automatically. The specified address is written in the

 

Mark Frame/Time/Block, or Mark Chapter/Track Register and

 

compared with the current address. When both values are equal,

 

Still Mode (CAV) or Pause Mode (CLV, CDs) occurs; then the

 

completion status is returned. Command completion also occurs

 

when lead-out is found before the specified address is reached.

 

 

 

IMPORTANT NOTE

When using the PLAY command with an address, the auto stop function will be released if any other command, including a status request, is sent to the player before the specified address is reached.

Use the Stop Marker command to achieve an auto stop PLAY function that will allow for status requests and maintain the end address marker.

3)If this command is sent when the player is in Open, Park or Spin- Up Mode, it is executed and the disc plays from the beginning of the program area. Once playback begins, the completion status is returned. Playback continues until another motion command is received.
