BVW Commands and Responses
The commands listed here are either implemented or stubbed (returning only a command acknowledgment) as indicated. Each command is identified by its command code and name.
Information listed here is intended to specify the minimum requirements for each command. Unless otherwise specified, the server implements all the capabilities for each command as specified in the Sony documentation. For more information, refer to the second edition or later of the Sony Videocassette Recorder Bvw Series Protocol Manual (part number 9-977-544-11).
Command list:
The following table lists the BVW protocol commands. The server returns an ACK response to each command, unless otherwise indicated.
| Command | Name | Return |
| 0X.11 | Device Type Request | The controller can distinguish Profile from BVW-75: If 00.11 is sent, returns 20.25 or 21.25 (for 525- or 625-line operation respectively). If 01.11.00 is sent, returns D8.00 (disk recorder). This allows the controller to decide whether to cue-up by a combination of FastForward/Rewind and CueUpWithData (faster with BVW-75) or CueUpWithData (faster with Profile). |

After TimerModeSelect (41.36) has been sent, CueUpWithData cues up using the following time codes: VITC if 41.36.00 is sent and VITC is displayed; LTC if 41.36.00 is sent and anything else is displayed; Timer1 if 41.36.01 is sent. |
