NORMAL AND COMPANION VIDEO STREAM APPLICATIONS

摘要

Normal video streams (21) comprise video channels at higher resolutions and companion video streams (22) comprise the video channels at lower resolutions. By supplying the video channels from the companion video streams (22) to screen devices (31, 32) for displaying at least parts of the video channels (51-57) from the companion video streams (22) separately from the video channels from the normal video streams (21), additional applications are possible. First screen devices (31) comprise screens for displaying video channels (41) from the normal video streams (21) and the at least parts of the video channels (51-57) from the companion video streams (22) separately from each other. The at least parts of the video channels (51-57) from the companion video streams (22) may be displayed as thumbnails on or near the displayed video channels (41) from the normal video streams (21). Second screen devices (32) comprise screens for displaying the at least parts of the video channels (51) from the companion video streams (22) separately from the first screen devices (31).
