  • Patent number: 4670881
    Abstract: A method of correcting errors in the information and control data of a video format signal containing redundant parity check bits, wherein the information data bits and associated parity check bits are assigned to the addresses located in an information data block and the control data bits and the associated parity check bits are assigned to the addresses located in a control data block, the two data blocks being carried on the video format signal. Prior to reproduction of the video format signal, the data blocks are extracted from the signal and are loaded into a memory whereupon the information data bits and then the control data bits are corrected by the respectively associated parity check bits.

  • Patent number: 4654853
    Abstract: A data transmission method in which data of different types is transmitted and errors detected and corrected optimally for the particular type of data transmitted. A check word is inserted into each group of a plurality of data groups, and a control code is also provided representing the coding method on which the check word is based. The data groups including the check word are transmitted together with the control code. At the receiving end, the control code is separated from the transmitted signal and used to detect the coding method on which the check word is based. Then, error detection and error correction are performed in accordance with the detected coding method.
