Abstract
Abstract A television system is disclosed which is independent of the scanning formats and is applicable to a high definition television system and fits the facilities offered by the emerging technologies as well as those of the prior art. The information related to the television pictures and supplied by a television pictures source according to the peculiar scanning format thereof are stored into a buffer or transit memory and then transferred on a transmission channel to another buffer or transit memory, from which the receiving apparatus takes the information according to its peculiar scanning format independent of that of the source.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
A television system independent of the scanning formats for the transmission of blocks of one or more frames, consisting of a television picture source, a transmission channel and a receiving apparatus displaying the transmitted television pictures, characterized in that between the television picture source and the transmission channel a first buffer or transit memory is provided, to which the source supplies the video information generated according to its peculiar scanning format, and between the transmission channel and the receiving apparatus displaying the transmitted television pictures a second buffer or transit memory is provided, from which the receiving apparatus takes the transmitted video information according to its peculiar scanning format which is independent of the scanning format of the television picture source, the transmission mode and the characteristics of the transmission channel being independent of the scanning formats both of the television picture source and the receiving apparatus.
Claim 2
Dependent Claim
147 words
A television system independent of the scanning formats for the transmission of blocks of one or more frames, consisting of a television picture source, a transmission channel and a receiving apparatus displaying the transmitted television pictures, characterized in that between the television picture source and the transmission channel a first buffer or transit memory is provided, to which the source supplies the video information generated according to its peculiar scanning format, and between the transmission channel and the receiving apparatus displaying the transmitted television pictures a second buffer or transit memory is provided, from which the receiving apparatus takes the transmitted video information according to its peculiar scanning format which is independent of the scanning format of the television picture source, the transmission mode and the characteristics of the transmission channel being independent of the scanning formats both of the television picture source and the receiving apparatus.
Claim 3
Dependent Claim
34 words
The television system of claim 1, characterized in that the screen is formed of 7 x 4 blocks of 256 x 256 pixels each, thus leading to a total of 1792 x 1024 pixels.
Claim 4
Dependent Claim
16 words
The television system of claim 1, characterized in that the format of the screen is 1.75:1.
Claim 5
Dependent Claim
32 words
The television system of claim 1, characterized in that the 1360 pixels per line from an aspect ratio of 4:3 are converted into 720 pixels per line with a ratio of 17:9.
Claim 6
Dependent Claim
31 words
The television system of claim 1, characterized in that the 1024 lines can be converted by a ratio of 16:9 into 576 lines, the additional line being able to be blanked.
Claim 7
Dependent Claim
31 words
The television system of claim 1, characterized in that 1026 lines can be converted by a ratio of 19:9 into 486 lines, the exceeding three lines being able to be blanked.
Claim 8
Dependent Claim
19 words
The television system of claim 1, characterized in that the television camera format provides the sequential scanning of 1080.
Claim 9
Dependent Claim
75 words
A television system independent of the scanning formats for the transmission of blocks of one or more frames, characterized in that in case of two frames per block first the sum and then the difference of the frames of the block is transmitted, the receiving apparatus carrying out the algebraic sum of the received information and dividing the result by two in order to provide separately the information of the first and the second frames.
Claim 10
Dependent Claim
75 words
A television system independent of the scanning formats for the transmission of blocks of one or more frames, characterized in that in case of two frames per block first the sum and then the difference of the frames of the block is transmitted, the receiving apparatus carrying out the algebraic sum of the received information and dividing the result by two in order to provide separately the information of the first and the second frames.
Claim 11
Dependent Claim
44 words
The television system of claim 8, characterized in that in case of only one frame per block, only the sum of the frames of the block is transmitted and used at the receiving side, the difference of the frames of the block being zero.
Claim 12
Dependent Claim
31 words
The television system of claim 9, characterized in that in case of only one frame per block the resulting line frequency of a 1080-line sequentially scanning television camera is 27 kHz.
Claim 13
Dependent Claim
28 words
The television system of claim 9, characterized in that in case of only one frame per block, the total number of lines of the receiving apparatus is 1120.
Claim 14
Dependent Claim
19 words
The television system of claim 11, characterized in that the line frequency of the receiving apparatus is 28 kHz.
