MULTIPAGE TELETEXT DECODER

摘要

A teletext decoder system comprises a teletext data cache memory (17) for storing teletext data, and an input (11) for receiving a user-initiated command including a reference to a specific item in a teletext service. It is configured to maintain at least a first list, each entry in the list including information referring to an item of teletext, and to autonomously acquire and store teletext data referred to by the information included in at least the first list. The teletext decoder system is configured to add an entry to the first list including information corresponding to the reference only upon determining that teletext data referred to by the reference is absent from the teletext data cache memory (17). ® KIPO & WIPO 2007
