Abstract

A video re-coding method for converting a first video signal (1) encoded in a first format into a second video signal (122) encoded in a second format, each said video signal comprising a series of video-signal elements (n), the method comprising steps of: storing a plurality of successive video-signal elements of the received first video signal as first-signal elements (104); decoding said first-signal elements (104) to produce corresponding intermediate video-signal elements (112) having a format different from each of said first and second formats, wherein at least two decoding processing threads are implemented to decode the first-signal elements (104) in a time-shared manner; storing the intermediate video-signal elements (112) produced by the at least two decoding processing threads; encoding said intermediate video-signal elements (112) to produce corresponding second-signal elements (116) having said second format, wherein at least two encoding processing threads are implemented to encode the intermediate video-signal elements in a time-shared manner; and storing the second-signal elements produced by the at least two processing threads.
