AVC_VCR_CMD_OUTPUT_SIGNAL_MODE (Windows CE 5.0)
This command permits the caller to query the VCR subunits current interpretation of the type of signal format it is prepared to output, or to permit the caller to attempt to set the VCR subunit to output a specific type of A/V signal.
Parameters
- Command
This must be set to AVC_VCR_CMD_OUTPUT_SIGNAL_MODE. - CommandType
If the caller wants to query the current setting, this field must be set to AVC_VCR_CommandType_Status. If the caller wants to set the VCR subunit to output a specific mode, this field must be set to AVC_VCR_CommandType_Control. - u.OutputSignalMode.SignalMode
If the caller is querying the current setting, this field need not be initialized. If the caller is attempting to set the VCR to accept a particular signal mode, this field must be initialized to one of the flags in the following table.Flag Description OUTPUT_SIGNAL_MODE_SignalMode_SD_525_60 Standard Definition Digital Video, 525 lines, 60fps.

Return Values
- ResponseCode
The VCR subunit will return a specific value in this field, depending on the requested action and the capabilities of the subunits. A successful query will likely result in a value of AVC_RESPONSE_STABLE, while a successful control attempt will result in a value of AVC_RESPONSE_ACCEPTED. Other values are possible and are discussed in the description of IOCTL_VCR_AVCCMD. - u.OutputSignalMode.SignalMode
If the caller was attempting to query the current setting, and the query operation was successful, this field will contain the current setting, which should be one of the modes listed above.
Remarks
Most consumer equipment is likely to support a single type of signal or a variant such as NTSC and S-VHS NTSC, and not permit any other setting. Merely because a signal mode has an identifying number does not guarantee in any way that the VCR subunit will support it.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
