SYSTEM FOR MULTI-SCALED VIDEO

摘要

PURPOSE: A system for a multi-scaled video is provided to control the selection of the scaled video and to generate a multi-scaled video from at least two encoded video sources. CONSTITUTION: A system for a multi-scaled video includes a switch(25), a digital video decoder(27) and a frame buffer(28). The switch(25) switches between at least two encoded video sources each of which includes plurality of frames. The digital video decoder(27) is coupled with the switch and includes a depression scaling function generating depression scaled frames from the plurality of frames. The frame buffer(28) is coupled with the digital video decoder. A memory stores at least one depression scaled frames from the at least two encoded video sources.
