Abstract
A video decoder system automatically acquires program guide information from local and remote peripheral devices to form a composite program guide. Program guide information is received from a first source and access data is retrieved from memory. The access data is used to initiate communication automatically between the video decoder and a second source external to the video decoder. Program guide information retrieved from the second source together with program guide information provided by the first source is incorporated into a composite program guide for display. The communication may be initiated upon different conditions and a peripheral device and associated communication protocol may be identified from various sources of configuration information.
