Image information signal transmitting system with selective transmission of input data or extracted data |
摘要 |
A transmission system, of the type wherein input data to be transmitted is stored in blocks and less than all stored data is extracted from the blocks for transmission and the extracted data is subjected to interpolation to restore all of the data, includes computing circuits for obtaining respective differences between input data and restored data and between input data and stored data and the sums of such differences, and further computing and comparison circuits operating with such differences sums to effect selective transmission of the input data or the extracted data.
