Abstract (en)

[origin: WO2007012341A1] In a method for analogue transmission of a video signal from a video source to a video sync, in which the video signal contains a sequence of frames which are present with a first picture resolution and a first picture frequency at the video source, in which the sequence of frames for physical transmission is converted into a sequence of picture segments having a second picture resolution, which is lower than the first picture resolution, and having a picture frequency higher than the first picture frequency, in which the sequence of picture segments is transmitted from the video source to the video sync, and in which a sequence of frames having the first picture resolution is reconstructed from the transmitted sequence of picture segments at the video sync, the first picture resolution is greater than the picture resolution of a frame according to a video standard and the second picture resolution is equal to the picture resolution of a frame or field according to the said video standard. In addition to such a method, the invention also relates to a video source, a video sync, a pre-processor and a post-processor which are suitable for use in a method according to the invention.
