A television signal processor selectively processing each television signal transmitted by a plurality of different television systems and displaying the processed television signal using any of multiple displays having different synchronizing frequencies and aspect ratios. The television signal processor includes a signal processing device for decoding a received signal in accordance with the system generating the received television signal, and a control mechanism for processing a television signal from the signal processing device in accordance with specification data corresponding to a display for displaying the television signal.

Television signal processor for processing any of a plurality of

This invention relates to an image reproduction apparatus for performing video signal processing by utilizing a plurality of DSPs. A digital video signal is supplied to a DSP signal processor constituted by combining the plurality of DSPs, and programs to be supplied to the plurality of DSPs are time-divisionally switched on the basis of a transmission timing of the video signal, so that the DSP signal processor can execute a plurality of systems of processing operations, and many functions can be added without increasing a circuit scale.

Image reproduction apparatus with plural program processing

According to one aspect of the present invention, an apparatus for error correction is comprised of a data storing section for storing data to be corrected, the data including a data field and an error correction field comprised of a predetermined number of bits. The apparatus also comprises a data readout section for reading out, at a first timing, the data to be corrected from the data storing section into a first line, and for reading out, at a second timing, into a second line, the error detection section for fetching the data to be corrected as read out into the first line. The apparatus further comprises means for applying a predetermined operation to the data to be corrected, thereby generating, in synchronism with the second timing, correction data corresponding to the error data. A correction section is also used for periodically fetching both the data to be corrected as read out into the second line and the correction data generated by the error detection section. The data is also subjected to a predetermined correction processing to thereby produce corrected data. Finally, a data write section is used for storing into the data storing section the corrected data as output from the correction section.
