US RE40,606 E1 · Television signal processor that is operable to generate a television signal from broadcast waves with a plurality of different broadcast standards

Abstract

In an effective display area, an additional information recognizing part 203 recognizes a standard of a broadcast wave, refers to a ROM 212 and selects a target value, and provides an internal clock of a video data reading part 205 and an internal clock of an OSD data reading part 206 with the target value. At a retrace internal, on the other hand, the additional information recognizing part 203 notifies an additional information synthetic position deciding part 210 of the standard of the broadcast wave. The additional information synthetic position deciding part 210 selects from a ROM 211 a target value for reading the additional information applicable to the notified standard, and outputs the target value to an additional information reading parts 207. When the standard of the broadcast wave is changed, target values corresponding to the changes are responsively selected from the ROM 212 and the ROM 211.

Dependent claims

A television signal processor for processing a received broadcast wave and generating a television signal, said television signal processor comprising:

storage means for storing video data and additional information separated from the received broadcast wave and OSD data generated on a receiver;
read means for respectively reading the video data, the additional information and the OSD data from said storage means;
standard detection means for detecting a standard of the received broadcast wave;
timing control means for respectively controlling timing of said read means for reading the video data, the OSD data and the additional information from said storage means in correspondence to the standard detected by said standard detection means;
and
combining means for combining the video data, the OSD data and the additional information read by said read means as combined data to output the combined data as the television signal.
