Abstract
The disclosure is an automatic programming method for a tuner of a television and/or video recorder that makes use of data received by cable or terrestrial or satellite radio, and a device implementing this method. The method involves the transmission of a set of channel tables, each corresponding to a broadcasting station, using the CEEFAX standard. The television or video recorder memorizes the table corresponding to the postal ZIP code previously input by the user, then automatically programs the tuner. The invention is applicable for all types of television standards (PAL, PAL+, SECAM, NTSC, D2MAC, HDMAC, digital standards, etc.) and to all types of signal formats transmitted with the video signals.
