Estimating the term…
Teletext engines configured for specific tasks. One such Teletext engine indexes the page numbers of incoming Teletext pages, along with the addresses at which they are stored in the TV's memory. This index essentially provides a list of stored Teletext pages and their corresponding locations in memory, sorted by page number. In one embodiment, this list is sorted in numerical order of page number, and in another embodiment, the list is sorted according to the order in which the TV receives pages. When the TV is to display a particular Teletext page number, it simply checks the index to find the corresponding address. Armed with this address, the TV can quickly retrieve the correct Teletext page from memory, as it can simply look up the correct address without first conducting a laborious search of the entire memory. Page retrieval times can thus be reduced significantly.
A computer-readable index for use in a television viewing system configured to receive Teletext pages having page numbers, the television viewing system including a processor configured to facilitate the display of the Teletext pages, and a Teletext page storage in electronic communication with the processor and configured to store the Teletext pages at page addresses, the index comprising:
A television control apparatus for use in a television viewing system configured to receive Teletext pages having page numbers and to display a displayed Teletext page having a displayed Teletext page number, the apparatus comprising:
