Abstract

A system and method that selectively discards contents of a buffer memory containing audio-visual digital media content in response to a media switching event. The system includes at least one server in communication with a digital media source and connected to a network. At least one receiver is also connected to the network and includes a display device that presents audible and visual information to a user. The buffer memory can be located in either the receiver, server or both devices. Upon generation and detection of the media switching event, the contents of the buffer are discarded so as to minimize the time-delay of changing the display information.
