Patent ID: 7907665

Claim:
An apparatus comprising: an input circuit configured to (i) generate a first intermediate signal by multiplexing a plurality of input video signals, each of said input video signal being received through a different one of a plurality of channels and (ii) temporally decimate at least two of said input video signals using different time ratios on each of said at least two of said input video signals, said time ratios being based on different priorities of said channels; a storage circuit configured to (i) parse said first intermediate signal into a plurality of sequences, each of said sequences corresponds to a different one of said input video signals, (ii) store said sequences in a plurality of buffers, each of said buffers storing in a different one of said sequences and (iii) generate a second intermediate signal by time multiplexing said sequences from said buffers; and an output circuit configured to generate an output video signal by compressing a portion of each of said sequences in said second intermediate signal in a rotating pattern, each of said portions comprising a group of pictures.
