Abstract:
A method and a system for performing trick mode features in a personal video recorder without introducing a channel change delay during normal viewing. The method includes the steps of recording a video source signal and concurrently bypassing the video source signal to a display device, without experiencing any buffering delay associated with the recording step. During trick mode operation the bypassing step can be automatically terminated and a recorded version of the video source signal can be substituted and sent to the display. The bypassing step further can include substituting, without any buffering delay, an alternate video source signal in response to a user selection of an alternate video source signal channel. A user notification can be generated to acknowledge receipt of a trick mode command. The user notification can be terminated once the step of substituting the recorded version of the video source signal has been completed.
