[This is preliminary documentation and subject to change.]
To tune a channel number for a specific tuning device, your application performs the following process. First, it determines if the input source for video is from a tuner with the HasChannel property of the BPCDeviceBase object. If so, your application switches the tuner to the specified channel with the BPCDeviceBase object's Channel property. You can also use the ChannelAvailable method of the BPCDeviceBase object in your application to determine whether a tuner can tune to the specified channel before actually tuning to the channel.
