Command and Status

During normal operation, when a computer transmits commands to a DVD-
V8000, the player responds with the status message, ‘execution complete’.

Example

COMPUTER

DVD-V8000

(1) “Search to Frame 1000”

(2) Search Execution

⇐ (3)

Complete


(4) “Play to Frame 2000”

(5) Play Execution

⇐ (6)

Complete


NOTE: The length of a command string is limited to 32 characters. Please
refer to COMMAND STRUCTURE for additional information.

When using a computer to control the DVD-V8000 player, follow the
command protocols listed below:

• ASCII characters are used for actual commands and status response
• Command mnemonic is expressed as two (2) ASCII characters
• Uppercase letters are recommended; however, usually there are no

distinctions between the uppercase and lowercase letters

• Some commands require an argument

(e.g. Chapter number or speed)

• Use a command as the terminator of an argument


The player executes a command as soon as the carriage return <CR> is
received. The <CR> acts as the command line terminator.

Example

CH<CR>

:

Set Chapter for address mode

10SE<CR>

:

Search to Chapter 10


The player has a command buffer, which stores a command string of up to
32 characters in length.

Example

10SE 20PL<CR>

:

Search to Chapter 10 then play to 20


The command string enters the buffer with the first character and continues
sequentially from left to right. When the

<CR>

is entered, the commands are

executed sequentially beginning with the first command in the buffer. In the
example above, the first command is 10SE.

NOTE: The player ignores codes in the command string such as <SPACE>
