Method for Analog Transmission of a Video Signal
First Claim
1. A method for analog transmission of a video signal from a video source to a video sink, in which the video signal contains a sequence of frames which are present with a first image resolution and a first image frequency at the video source, the method comprising:
- converting the sequence of frames for physical transmission to a sequence of image segments having a second image resolution that is lower than the first image resolution, and having an image frequency that is higher than the first image frequency;
transmitting the sequence of image segments from the video source to the video sink; and
reconstructing a sequence of frames having the first image resolution from the transmitted sequence of image segments at the video sink, wherein the first image resolution is higher than the image resolution of a frame according to a video standard, and wherein the second image resolution is equal to the image resolution of a frame or field according to said video standard.

Abstract
A method for analog transmission of a video signal from a video source to a video sink is provided. The video signal contains a sequence of frames with a first image resolution and a first image frequency at the video source. The sequence of frames is converted to a sequence of image segments having a second image resolution that is lower than the first image resolution, and an image frequency that is higher than the first image frequency. The sequence of image segments is transmitted from the video source to the video sink, and a sequence of frames having the first image resolution is reconstructed at the video sink, the first image resolution is higher than the image resolution of a frame according to a video standard, and the second image resolution is equal to the image resolution of a frame or field according to the said video standard.
