IScanningTuner::SeekUp method (tuner.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The SeekUp method changes the channel to the next higher channel with valid programming.
Syntax
HRESULT SeekUp();
Return value
When the method succeeds, it returns S_OK. Otherwise it returns an HRESULT error code.
Remarks
This method returns immediately, and the seek continues in the background. The seek can be canceled by calling any other tuning operation.
Currently the DVB-C and DVB-S Network Provider filters do not implement this method, and return E_NOTIMPL. The method is implemented for DVB-T.
