IAMAnalogVideoDecoder::put_VCRHorizontalLocking
The put_VCRHorizontalLocking method specifies whether the video is a tape source or a broadcast source.
Syntax
HRESULT put_VCRHorizontalLocking( long lVCRHorizontalLocking );
Parameters
lVCRHorizontalLocking
[in] Specifies one of the following values.
| Value | Description |

Return Values
Returns an HRESULT value. Possible values include the following.
| Value | Description |

Remarks
The timing accuracy of synchronization pulses is typically poorer from a tape source than from a broadcast source. Setting the value to 1 tells the decoder to relax its standards, which leads to a better chance of maintaining sync.
