ARRANGEMENT FOR THE DPCM CODING OF TELEVISION SIGNALS USING FAST SIGNAL PROCESSING |
摘要 |
<p>In DPCM coders, respective estimated values are subtracted from digitized picture element signals and the estimated errors are employed for signal transmission following quantization and coding. Each estimated error is quantized with a fictitious, positive operational sign in a first programmable logic arrangement and, parallel thereto, is quantized with a fictitious negative operational sign in a second programmable logic arrangement. Of these two quantizing results, the correct result is selected via a multiplexer controlled by the actual operational sign of the estimated error.</p> |
