摘要： The invention relates to a system (101) for content analysis. The system (101) comprises an interface receiving a video signal in accordance with a first encoding standard, such as H.264. The interface is coupled to an extraction processor (107) which extracts video coding data from the video signal. The video coding data is fed to a conversion processor (109) which converts the video coding data to video coding data according to a second video encoding standard, such as MPEG-2. The conversion converts the extracted video data to video coding data related to a common encoding block size, for example, by grouping smaller blocks and averaging the video parameters to provide video coding parameters related to larger block sizes. The converted data is fed to a content analysis processor (111) which performs content analysis based on the converted data. A content analysis algorithm for one video encoding standard may thus be used for a different video encoding standard.

摘要： The invention relates to a video encoding apparatus (100) comprising a video analysis processor (101) and a video encoder (103). The video analysis processor (101) comprises a segmentation processor (109) which divides a picture into a plurality of picture regions. A picture characteristic processor (111) determines picture characteristic, such as a texture level, for one of the regions, and in response a video encoding selector (113) selects a video encoding parameter for that region. The video encoding parameter is fed to the video encoder (103) wherein a video encode processor (I 19) encodes the picture using the video encoding parameter determined by the external analysis by the video analysis processor (101). The encoded picture is fed back to the video analysis processor (101) and the process is iterated until a desired encoding performance is achieved. The apparatus is particularly suitable for H.264 encoding and allows for improved performance from a selection of encoding parameters based on an external analysis.
