Method of content adaptive video encoding
First Claim
1. A decoder comprising:
- a processor; and
a computer-readable storage device having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;
receiving header information associated with an assigned predefined content model for a region of interest in video content, wherein the region of interest comprises a rectangular-based region covering less than a full frame identified on a frame-by-frame basis by a first sub-segment in the respective region of interest and a last sub-segment in the region of interest, to yield a portion of the full frame not covered by the region of interest, and wherein the assigned predefined content model is assigned to the region of interest and not to the portion of the full frame; and
decoding the region of interest, based on the header information and the assigned predefined content model, differently than the portion of the full frame.

Abstract
A method of content adaptive encoding video comprising segmenting video content into segments based on predefined classifications or models. Based on the segment classifications, each segment is encoded with a different encoder chosen from a plurality of encoders. Each encoder is associated with a model. The chosen encoder is particularly suited to encoding the unique subject matter of the segment. The coded bit-stream for each segment includes information regarding which encoder was used to encode that segment. A matching decoder of a plurality of decoders is chosen using the information in the coded bitstream to decode each segment using a decoder suited for the classification or model of the segment. If scenes exist which do not fall in a predefined classification, or where classification is more difficult based on the scene content, these scenes are segmented, coded and decoded using a generic coder and decoder.

15. A computer-readable storage device having instructions stored which, when executed by a computing device, result in the computing device performing operations comprising:
-
receiving header information associated with an assigned predefined content model for a region of interest in video content, wherein the region of interest comprises a rectangular-based region covering less than a full frame identified on a frame-by-frame basis by a first sub-segment in the respective region of interest and a last sub-segment in the region of interest, to yield a portion of the full frame not covered by the region of interest, and wherein the assigned predefined content model is assigned to the region of interest and not to the portion of full frame; and decoding the region of interest, based on the header information and the assigned predefined content model, differently than the portion of the full frame. - View Dependent Claims (16, 17, 18, 19, 20)
