METHOD AND APPARATUS FOR SIMULTANEOUS DISPLAY OF MULTIPLE AUDIO/VIDEO PROGRAMS TRANSMITTED OVER A DIGITAL LINK

摘要

Simultaneous display of multiple audio/video (AV) programs transmitted over a digital link (106) is described. At a source device (102), at least one non-composited digital transport stream is generated from the plurality of AV programs. The at least one non-composited digital transport stream is augmented with control information. The control information is operative to invoke simultaneous display of the plurality of AV programs on a display device (124). The at least one non-composited digital transport stream is then transmitted as augmented over the digital link (106). At a sink device (104), at least one non-composited digital transport stream having the plurality of AV programs is received over the digital link (106). Control information is extracted from the at least one non-composited digital transport stream. The plurality of AV programs are identified within said non-composited digital transport stream in response to the control information. The identified AV programs are then simultaneously displayed on the display device (124).
