3.3Command 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>
