Abstract

Abstract The invention improves the reconstitution of video signals which are transmitted as sequential luminescence fields (odd and even), whereby, e.g. the relative position of the fields is determinative of color content. The three color and channel reconstituted signal is composed of one on-line signal, one stored and recalled signal, and one interpolated signal.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 190 words
A TV system, wherein color TV information is broken down into a plurality of fields of monochromatic color information with particular association of color and fields, e.g. in terms of relative occurrence or other color content identifying information for any particular sequence of fields as transmitted, the improvement comprising: means for alternatingly composing odd/even multicolor field signals, having a plurality of color identifying outputs; means for extracting an on-line signal from the transmitted signal and feeding the same alternatingly to different outputs of said composing means, depending on the respective color; storage means for such transmitted signal and storing them separately for the different fields; means for cyclically variably extracting from the storage means, field signals of color information different from the current on-line signal but pertaining to the same type of field (odd or even), and feeding same as second output to said means for composing; and means for extracting from the storage means field signals of still different color and pertaining to a different type of field (even or odd) and interpolating an image content, and feeding same as a third output to the said means for composing.
Claim 2
Dependent Claim 190 words
A TV system, wherein color TV information is broken down into a plurality of fields of monochromatic color information with particular association of color and fields, e.g. in terms of relative occurrence or other color content identifying information for any particular sequence of fields as transmitted, the improvement comprising: means for alternatingly composing odd/even multicolor field signals, having a plurality of color identifying outputs; means for extracting an on-line signal from the transmitted signal and feeding the same alternatingly to different outputs of said composing means, depending on the respective color; storage means for such transmitted signal and storing them separately for the different fields; means for cyclically variably extracting from the storage means, field signals of color information different from the current on-line signal but pertaining to the same type of field (odd or even), and feeding same as second output to said means for composing; and means for extracting from the storage means field signals of still different color and pertaining to a different type of field (even or odd) and interpolating an image content, and feeding same as a third output to the said means for composing.
Claim 3
Dependent Claim 27 words
The improvement as in claim 1, said storage means including two stores for each field both of them alternatingly receiving image increments from the same video line.
