LaserBarcode 2™ Commands & Logo (cont.)

Each LaserBarcode command is listed below with a description of how the player responds when the code is scanned and transmitted to the player. Remember, all LB2 commands are supported only by players that carry the LB2 logo. Players that carry the original LaserBarcode logo will play LB2 “Original Commands”, but do not support LB2 “Extended Commands”.

A. Independent LaserBarcode 2 Commands

There are 26 independent LB2 commands: Fourteen “original” independent LaserBarcode commands and 12 “extended” independent LaserBarcode commands.

Original Independent Commands (LB & LB2)

1.Video On - Sets the video control attribute to “on.” Video is turned on during playback.

2.Video Off - Sets the video control attribute to “off.” Video is turned off during playback.

3.A-Stereo- Sets the audio control attribute to “analog stereo,” plays back left and right analog audio channels simultaneously.

4.A-Ch 1/Left - Sets the audio control attribute to “analog channel 1,” plays back analog left channel only.

5.A-Ch 1/Right - Sets the audio control attribute to “analog channel 2,” plays back analog right channel only.

6.Audio Off - Sets the audio control attribute to “off,” mutes both analog and digital audio playback.

7.Play - Instructs the player to play the disc:

a)If player is in Park Mode, the Play command instructs the player to spin up and begin playing the disc.

b)If player is in Still or Pause Mode, the Play command instructs the player to resume playback of the disc from that point.

8.Pause - Instructs the player to halt playback of the disc and squelches the video. Pause can be used with both CAV and CLV discs.

9.Step Forward - Instructs the player to step 1 frame in the forward direction. Step Forward can only be used with CAV discs.*

10.Step Reverse - Instructs the player to step 1 frame in the reverse direction. Step Reverse can only be used with CAV discs.*

11.Park Disc - Instructs the player to stop playback, spin down the disc and put the player in Park Mode.

12.Clear - Instructs the player to clear a stop marker during motion sequences. For example, if a scanned barcode instructs the player to search to frame 1000 and play to frame 3000, sending the Clear command will clear the frame 3000 stop marker and playback will continue beyond that point on the disc.

* Step Forward and Step Reverse can also be used with CLV discs, if they are played on an LD-V8000 player.
