this device before sending another. The response from this device can contain one byte, or a plurality of bytes like the CTL data. Moreover, for a command like EJECT that usually requires a long execution time, in addition to an ordinary response that is returned immediately after the receipt of the command, there exists another response that denotes the execution result when the operation is completed. According to the RS-232C protocol, commands, changes of this device, and parameters will be all defined as commands. For further details, please refer to “5. Detailed Description of Commands” (page 13). Some simple examples are shown below. 1. Commands used to control this device (1-byte response is returned from this device) The case of a command having no parameter : The case of a command having parameters : There are 2 responses which are ACK and NAK. ACK ....to be returned when the command is received normally. NAK....to be returned when a transmission error is detected, or an undefined command is received. 2. Commands used to sense the status of this device (multi-byte response is returned from this device) 3AH 0AH This device Host Command Response D8H C5H 30H 40H 0AH 0AH 0AH 0AH This device Host Command Command Parameter 1 Parameter n Response Response Response Response D7H 80H This device Host Command Response 1 00H Response n

This device will return a response after the execution of each following command: EJECT, MEMORY SEARCH, INDEX SCAN FWD, REPEAT etc. There exist 3 responses from this device, which are COMPLETE, NOT TARGET, TRAY OPEN. COMPLETE.......to be returned when a command is executed and ended normally. NOT TARGET...to be returned when a specified target is not found. TRAY OPEN .....to be returned when the disc tray is open. 4. Each command is basically 1-byte long, but there are some which are the combinations of 2 different commands 1) Before receiving a response from this device, you shouldn’t send any other command. However, if there is no response from this device for more than two sec. after sending a command, it is necessary to take some measures because the transmission could have not been done correctly. 2) No other command can be inserted between an extended command and a secondary command. Multi-byte setting commands When specifying multi-byte setting commands, if even a single byte is defined incorrectly or cannot be received, the entire command and all its settings will be ignored.

5-1. Response Command This is a command to be sent from this device after receiving a command from Host. Below are the commands supported by this device. 5-1-1. COMPLETE (01H) COMPLETE is returned when the execution of a SEARCH, REPEAT or MEMORY SEARCH command is completed. However, during the execution of any of these commands and before COMPLETE is returned, if another DVD editing command or CL command is newly received, the current execution will be cancelled and since the new command will be executed, COMPLETE will not be returned. 5-1-2. TRAY OPEN (03H) (HVO-550MD only) This command informs that the disc tray was opened by the EJECT command or the pressing of the EJECT button of this device. 5-1-3. NOT TARGET (05H) This command informs that the specified time data or CTL is not found in the disc during the execution of a SEARCH, REPEAT or MEMORY SEARCH command. In this case, the execution will be discontinued. 5-1-4. ACK (0AH) This command is returned when a defined command is normally received. However, for STATUS SENSE commands that make requests for data, not ACK but only data will be returned. At that time, even if a command could not be executed (e.g., in the case of a PLAY command when there is no recorded data), ACK will be returned. 5-1-5. NAK (0BH) NAK is returned when a command that is not defined in the current mode (e.g. a numerical command in a mode other than numerical input mode) or a command that cannot exist in the numerical input mode (e.g. the PLAY command) is received, or when a transmission error is detected.

time data and CTL from this device. There are 3 formats available (byte-parameter input, multi-byte parameter input, multi-type parameter input) as shown below. Byte-parameter input This is used to specify a 1-byte numerical parameter. NAK will be returned if a non-numerical command is entered. FWD SHUTTLE and REV SHUTTLE commands belong to this type. Ex) Double speed playback Multi-byte parameter input This is used to specify a multi-byte numerical parameter. Such a numerical parameter is composed of a plurality of bytes including a sign code, and is always ended by ENTER (40H). Each command has a fixed maximum number of bytes, and when this value is exceeded, the numerical part that comes behind is valid. However, the sign command is given a special treatment. CTL PRESET and SEARCH commands belong to this type. Ex) An example of setting the preset value of CTL to “0:12:34:12” B5H 36H 0AH “ACK” “ACK” 0AH This device Host Speed data Command D8H 9AH 30H 0AH “ACK” “ACK” “ACK” “ACK” 0AH This device Host Command 0AH 0AH 31H “0” “1” 32H 33H 34H 0AH “ACK” “ACK” “ACK” “ACK” 0AH This device Host 0AH 0AH 31H “4” “1” “2” “3” 32H 40H 0AH “ACK” “ACK” 0AH This device Host “2” “ENTER”

This format is used to specify a plurality of numerical parameters separated one by one by an ENTER code. Each numerical parameter is similar to a multi-byte parameter. SEARCH TO TARGET TIME and REPEAT commands belong to this type. Ex) An example of setting the preset values of REPEAT to Title 2, and “0:12:34:12” (to be repeated 10 times). When a numerical parameter is used with the multi-byte parameter input format or the multi-type parameter input format described above, the lastly entered number can be erased by using the C.E. command. Moreover, both the sign and the number may need not be entered, and when omitted, “+” and “0” will be respectively assigned. If a number is entered with fewer digits than pre-determined, high-order digits are considered omitted. When it has some extra digits, then the extra high-order digits will be eliminated and the remaining digits represent the valid value. Here, the sign is not included, but it is always given a higher priority. When a sign command is used, a keyed-in sign will clear out all previously entered numbers. Furthermore, since a sign cannot be erased by C.E command, if it was wrongly entered, a new sign together with all other numbers would need to be re-entered. Ex) Some input patterns of CTL data are shown below -0 1 2 4 C.E. 3 4 5 2 ENTER results in -0:12:34:52 ENTER results in +0:00:00:00 2 3 1 0 ENTER results in +0:00:23:10 -2 1 2 3 4 5 4 3 2 ENTER results in -2:34:54:32 -1 2 3 4 + 1 0 ENTER results in +0:00:00:10 5-2-1. Numerical Commands 0 to 9 (30H to 39H) They denote respectively the numerical values 0 to 9. Note D9H 91H 30H 0AH “ACK” “ACK” “ACK” “ACK” 0AH This device Host Command 0AH 0AH 32H “0” “2” “ACK” 0AH 40H “ENTER” Title 30H 31H 32H 0AH “ACK” “ACK” “ACK” “ACK” 0AH This device Host 0AH 0AH 33H “0” “1” “ACK” 0AH 34H “2” Time “3” “4” 31H 32H 40H 0AH “ACK” “ACK” “ACK” “ACK” 0AH This device Host 0AH 0AH 31H “ENTER” “1” “ACK” 0AH 30H “0” Time “1” “2” “ACK” 0AH 40H “ENTER” Repeat number

They are used to add a sign (+, _) to a numerical value. 5-2-3. ENTER (40H) This is used to mark the end of an entered numerical parameter. 5-2-4. Character Commands A to Z (41H to 5AH), a to z (61H to 7AH), SPACE (20H) They denote respectively characters A to Z, a to z, and a space. They are used in commands such as SET DISC NAME, SET TITLE NAME, and SET TITLE INFO.

5-3-1. C.E. (41H) This is used to suppress an error status or to delete a single character lastly entered. In addition, if this command is executed during concurrent recording to external media, the concurrent recording will be canceled. This command however cannot be used to erase an entered sign. In order to do that, please use a sign command to enter a new sign for replacement. For more details, refer to “5-2. Numerical Command” (page 14). 5-3-2. C.L. (56H) This is used to cancel an error status, and at the same time, to cancel the current command. After sending a command having a numerical parameter, and before this numerical parameter is fixed, if a C.L. command is entered, the entry of this numerical parameter will be stopped and the sent command will be cancelled. In addition, if this command is executed during concurrent recording to external media, the concurrent recording will be canceled. 5-3-3. EXP-1 (D8H), EXP-2 (D9H), EXP-8 (DFH) EXP-1, EXP-2 and EXP-8 are the 1st, the 2nd and the 8th extended commands. They will become effective only when used in pairs with their secondary commands. However, if there is another command that is inserted between an extended command and its secondary command, this extended command will be cancelled and NAK will be returned. Ex) The KEY INHIBIT ON command is normally executed Ex) If the extended command is followed by a command other than its secondary command, the KEY INHIBIT ON command will not be executed normally. D8H 94H 0AH “ACK” “ACK” 0AH Repeat number Host Command (secondary) EXP-1 D8H 3AH 0AH “ACK” “NAK” 0BH This device Host Command (other than secondary) EXP-1 94H “NAK” 0BH Command (secondary)

5-4-1. AUDIO MUTE ON (24H) This command puts the audio on muting. 5-4-2. AUDIO MUTE OFF (25H) This command cancels the muting setting of the audio output. 5-4-3. VIDEO MUTE OFF (26H) This command cancels the muting setting of the video output. 5-4-4. VIDEO MUTE ON (27H) This command puts the video on muting. 5-4-5. MEMORY (5AH) This memorizes the title no. and time (as frames or GOP 1)) of the current position. By starting MEMORY SEARCH after executing MEMORY, the current position will be moved to the memorized one. 1) GOP (Group of Pictures): A unit of MPEG images in which multiple frames are bundled together. It consists of I (in-frame coding image), P (progressive direction predicted coding image), and B (both direction predicted coding image) pictures. This device treats 15 frames as 1 GOP for NTSC and 12 frames as 1 GOP for PAL. MEMORY SEARCH will continue with the previously memorized values even if a change occurs during its execution. Memorized values can be reset, by executing TITLE ERASE or by switching OFF the power supply. 5-4-6. KEY INHIBIT ON (EXP-1 + 94H) This disables playback operations from the front panel and CUSTOM button key inputs. Only the EJECT, MENU, BACK, and ENTER buttons and the up, down, left, and right arrow buttons when a menu is displayed will operate. 5-4-7. KEY INHIBIT OFF (EXP-1 + 95H) This command makes the inputs from the front panel effective. 5-4-8. FULL EE ON (C4H) This command changes the status to FULL EE. 5-4-9. FULL EE OFF (C5H) This command cancels the FULL EE status. 5-4-10. REC REQUEST (FAH) This command enables compatibility with the DVO-1000MD.
