Video signal processing method and apparatus for use with plural television systems |
摘要 |
In shuffling used as an efficient coding method for an input digital video signal, input digital television signals of different standards are judged in an input judging circuit, the judged information is sent out into a memory write control circuit and a memory read control circuit. The memory write control circuit determines the offset value of the vertical address according to the judgement signal, and writes the input signal at a position corresponding to the screen of the determined shuffling region of the shuffling range corresponding to each signal in the shuffling memory, or writes the block out of the shuffling range into the shuffling memory according to the specified control method in the vacant region of the shuffling range. The memory read control circuit changes over the offset value of the vertical address to be read out from the memory and the address control according to the judgement information.
