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.

Abstract: A graphics processing unit in which the caching algorithm changes at the end of a line (or alternatively when the data from the beginning of the current line comes up for discard). This avoids the problem of continuous misses at the start of a new line, which can occur when the texture cache is not big enough to hold a full line's worth of data.
