TL;DR: In this article, a method and apparatus for assembling digital data representing a T. V. picture was described, including the steps of producing digital words representing a line of video, producing a digital code indicative of each line, combining the digital codes and the digital words for each line of the video, and storing the words line-by-line until a number of lines at least equal in number to the number of words in a field has been stored.
Abstract: A method and apparatus are disclosed for assembling digital data representing a T. V. picture, including the steps of producing digital words representing a line of video, producing a digital code indicative of each line of video, producing a digital code indicative of the field containing the line, combining the digital codes and the digital words for each line of video, storing the digital words line-by-line until a number of lines at least equal in number to the number of lines in a field has been stored, and reading out the digital words. One advantage afforded by the invention is that for fast winding during editing, the stored field of video can be made up of lines derived from a number of different fields, thereby not only reducing the amount of storage required, but also speeding up the process.

TL;DR: A survey of the coding concepts developed for digital television coding is presented and directions of the present research in this field are indicated.
Abstract: Digital television coding aims at representing a television signal by as few binary symbols as possible to save channel and storage capacity in digital transmission and processing systems. In this paper, a survey of the coding concepts developed for digital television coding is presented and directions of the present research in this field are indicated.

TL;DR: This chapter addresses the process by which the digital operation of the person is coupled with words, which may be divided into two classes—signs and symbols.
Abstract: In the previous chapter we addressed the analogic and digital modes of data processing, which are seen throughout all living systems, placing the human animal on a continuum with other species. In this chapter we will address the process by which the digital operation of the person is coupled with words. These words may be divided into two classes—signs and symbols.
