Abstract
Apparatus and methods for reducing the tune-time delay in a television appliance having a PVR subsystem are provided. A first signal path provides a desired television signal for display without a PVR associated tune-time delay. The first signal path includes a first buffer for buffering the television signal and a decoder for decoding the buffered television signal for display. The second signal path includes a storage device for storing a copy of the buffered television signal, and a second buffer for buffering the stored television signal when a trick play mode is selected. The decoder decodes the buffered television signal to provide the requested trick play mode. A switch is provided under control of the processor for switching between display of the television signal via the first path and display of the trick play mode via the second path.
