Abstract:
1. An apparatus comprising: an input circuit configured to generate a first intermediate signal from a plurality of input video signals, wherein said first intermediate signal comprises an encoded digital video signal; a content analyzer circuit configured to present one or more flags in response to said first intermediate signal; a storage circuit configured to (i) store and organize said first intermediate signal into a plurality of sequences, each of said plurality of sequences corresponding to one of said input video signals and (ii) generate a second intermediate signal from said plurality of sequences; and an output circuit configured to generate an output encoded bitstream in response to said second intermediate signal, wherein said output circuit is further configured to embed intra picture information into said output encoded bitstream in response to said one or more flags, wherein (i) said intra picture information allows said content analyzer circuit to generate said flags in response to temporal and spatial areas of interest in said encoded digital video signal, (ii) in a first mode, said content analyzer circuit (a) determines regions of greater interest and regions of lesser interest within a given channel, and (b) applies a first type of processing to said regions of greater interest comprising two or more frames and a second type of processing to said regions of lesser interest comprising two or more frames, wherein said two or more frames of said regions of greater interest and said two or more frames of said regions of lesser interest are permanently stored by said storage circuit after said first type of processing is applied to said regions of greater interest and said second type of processing is applied to said regions of lesser interest, and (iii) in a second mode, said content analyzer circuit applies said second type of processing to all frames within said given channel and said storage circuit permanently stores all of said frames of said given channel after said second type of processing is applied.
