摘要： A content augmentation process for personal recordings involves a service center (SC). The service center (SC) collects personal recordings from various different users via a network so as to constitute a database (DB) of personal recordings. The service center (SC) identifies personal recordings within the database (DB) that concern a particular scene and that are mutually complementary so as to form a selection of personal recordings (FSRR) for content augmentation purposes. The service center (SC) applies a content augmentation process (AUGP) to the selection of personal recordings (FSRR) so as to obtain an enhanced representation (CA).

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.
