The method, decoder, and interactive systems to combine multiple streams of video encoded in MPEG-4

摘要

Method, system and decoder interactive to combine multiple video streams encoded in MPEG. A system and method for simultaneous transmission and rendering of multiple streams of digital video signal encoded in MPEG in an interactive television application are disclosed.Simultaneous transmission and rendering of multiple streams of digital video signal encoded in the MPEG application in an interactive television includes, generally, to determine a value for a code of the display position corresponding to a display position of each f Atia from each of the chains of video encoded in MPEG.To change the value of the code position of display of each slice of each of the chains of video encoded in MPEG, as necessary, (334), and interim each slice of each of the chains of video encoded in the MPEG modified into a single composite video stream (336). The modification, preferably maintains alignment of bit of the code of the display position within a byte.The current video encoded in MPEG video streams are optionally encoded MPEG-1 or MPEG-2 and the code position of display is optionally a code word of variable length increment of address of macrobloco and / or at least one byte of a code. The beginning of the slice.
