IAMAnalogVideoDecoder::get_VCRHorizontalLocking

The get_VCRHorizontalLocking method determines whether the VCR horizontal locking has been set.

Syntax

HRESULT get_VCRHorizontalLocking(
  long *plVCRHorizontalLocking
);

Parameters

plVCRHorizontalLocking

[out]  Pointer to a variable that receives one of the following values.

Value Description
TRUE VCR horizontal locking is set.
FALSE VCR horizontal locking is not set.

Return Values

When this method succeeds, it returns S_OK. Otherwise it returns an HRESULT error code.

Remarks

VCRs might have bad sync timing (due to tape slips, tape noise or dropouts, and the mechanical nature of the recording mechanism). Having the horizontal locking on tells the decoder to relax its standards, which leads to a better chance of maintaining sync.
