TH23357B - Video suppression device for independent reduction of odd and even segments. - Google Patents

Abstract

In the image reduction system, the odd (17) and even (16) portions of the image signal are reduced independently in the order of reduction patterns within the image frame and between the reduced and even odd and even portions of the reduced data frame. The free form is crossed (14) for transmission. The crossed parts that are Double-reduced data within an image frame. It is centered between adjacent segments of the odd number of reduced data within the Image pane. Cross-sequences are used (21) receivers with 2 times the amount of data entering the signal for decoding without increasing the amount of transmitted data.

Claims (7)

1. A system for reducing image data consists of a video signal source for giving the sequence of odd and even segments of the video signal. The subsequent odd and even numbers form the frame of the signal. Responding to the signal to reduce the odd number of the video signal independent of that even number. And to reduce the even portion of the video signal regardless of the odd portion The reduction encodes a certain number of odd segments according to the intra-frame reduction scheme and the remaining odd segments. According to the predicted reduction scheme And encode a number of pairs According to the reduction pattern within the frame And encode the remaining even numbers According to the predicted reduction scheme And where the even number portion The portion that was reduced by the internal reduction model came from a different frame than the odd number that was reduced by the reduction model within that frame, and the section for sending the reduced portion. 2. The system referred to in claim 1 in which the reduced even parts within the frame take place in the middle order between the subsequent odd parts that are reduced within the frame. 3. The system stated in claim 2, the even reduced numbers within the frame are distributed between the reduced odd segments within the adjacent frames. 4. The system mentioned in claim 1, the source consists of a portion for the signal portion. The section connected to the portion of the video signal. And there are one and two exit points for the alternating distribution of the adjacent parts at the first and second exit points. 5. The system referred to in claim 4 in which the reduction path consists of the first reducer attached to the primary exit point for an odd reduction. The aforementioned first reducer is programmed to reduce every odd number of Nth occurrences according to the reduction scheme within that frame when N is an integer greater than 3. The second reducer is connected to the second output point. For even reducing the number of parts The aforementioned second-order reducer is programmed to reduce every even number that occurs at Mth according to the reduction scheme within that frame when M is an integer greater than 3 and a path for joining even and odd segments at Reduced 6. The system referred to in claim 1 where the method for such transmission consists of a path for separating the sections that are integrated into the transmission block with the respective section symbol. 7. The system mentioned in claim 1, in which the method of reduction is programmed to reduce every The even number of Nth times followed by the internal reduction scheme when N is an integer greater than 3 and is programmed to reduce every Even number of occurrences occurring at Mth according to the intra-frame reduction scheme when M is an integer greater than 3.
