Title: TV signal digital transmission system - scanning frequency for coding is lower than twice highest signal frequency
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N7/34
Filed: 1974-08-01
Abstract: Scanning values are generated during decoding, which appear at twice the scanning frequency. If edges are present scanning values between the original values are obtained from original scanning values in the preceding line. If edges are absent values are obtained by mean value formation from two consecutive original scanning values. The DPCM coded signals are applied to a DPCM decoder and to a circuit for an edge signal derivation. PCM signals at the decoder output are applied to a delay line and to an adder. A delay line delays PCM signals by one scanning period and applies the delayed signal to the adder's second input.
