Abstract: A system of encoding an original binary digital video signal comprised of a plurality of first 8-bit words having an absolute value and a digital sum variation, to produce an encoded binary digital video signal, converts each first 8-bit word into a second 8-bit word also having an absolute value and a digital sum variation such that, with respect to predetermined groups of correlative first 8-bit words, that is, first 8-bit words having absolute values which are close to each other, second 8-bit words corresponding to the first 8-bit words in each respective group have the same digital sum variation; and then inverts every alternate m second 8-bit words, where m=1, 2, 3 . . . , to form the encoded binary digital video signal with substantially reduced DC content while maintaining the same recording bit rate.

Encoding apparatus for digital signal with improved block channel coding
Kazuharu Niimura
- 27 Mar 1992
TL;DR: In this article, an encoder (3) separates an input digital signal including m bits into the first group and the second group, and encodes each piece of data in the latter group to two code words each including n bits in one-to-two correspondence.

Method of dc-free 8/9 nrz coding using a unique sync word pattern
Bruce E. Busby
- 06 Apr 1987
TL;DR: In this paper, the authors proposed an 8/9 encoding scheme where the improvement comprises selectively outputting, in response to a sync control signal, a first and a second 9 bit code word that uniquely identify a synchronization point in the 9 bit data word stream.

System for transmitting a digital video signal
Takao Inoue
- 14 Dec 1988
TL;DR: In this paper, the authors considered the transmission of digital video data signals, for example, in a digital video tape recorder, a luminance signal and first and second chrominance signals, such as R-Y and B-Y, are individually sampled to provide respective digital luminance data signals and first-and second digital chrominance data signals for forming a high-definition video picture.

Method and apparatus for code conversion of binary to multilevel signals
Malcolm Betts,Alan F. Graves,Frederick Michael Pascoe,James E. Dilley +3 more
- 18 May 1981
TL;DR: In this article, one word of each frame is selectively inverted relative to another in order to maximize the summation of all the numerical values of the differences between adjacent symbol levels, and then both words of the frame are selectively inverted to minimize the running digital sum of the signal.

Video signal converting system having quantization noise reduction
Sawagata Kiyoshi
- 21 Jun 1976
TL;DR: In this paper, the clamp levels at every horizontal synchronizing interval are randomly shifted before conversion, whereby quantization noise signals can be scattered on a displayed image by reclamping after a reconversion of the signal.
