VIDEO SIGNAL PROCESSING APPARATUS WITH A TELETEXT PROCESSOR WITH A TELETEXT PROCESSOR

摘要

The video signal processing apparatus includes a teletext processor 107 having a nonvolatile memory 115 for storing characters displayed on the screen, the characters being recorded with a redundancy-decrement code. The control device 111 ensures that the data is decoded when the data is read and retransmitted to the device 113 which generates the screen drive signal. Because the characters are compressed before being stored, the teletext processor 107 can be produced as an integrated circuit even when a wide range of character sets need to be processed.
