发明名称 Interactive television system and method for simultaneous transmission and rendering of multiple encoded video streams
摘要 A system and method for the simultaneous transmission and rendition of multiple MPEG-encoded digital video signal streams in an interactive television application is disclosed. Simultaneous transmission and rendition of multiple MPEG-encoded digital video signal streams in an interactive television application generally comprises determining a value for a display position code corresponding to a display position of each slice of each of the MPEG-encoded video streams, modifying the value of the display position code of each slice of each of the MPEG-encoded video streams as necessary (334), and interleaving each slice of each of the MPEG-encoded video streams as modified into a single composite video stream (336). The modifying preferably maintains bit-alignment of the display position code within a byte. The MPEG-encoded video streams are optionally MPEG-1 or MPEG-2 encoded video streams and the display position code is optionally a macroblock address increment variable length codeword and/or at least a byte of a slice startcode.
