    摘要: A system provides product annotation in a video to one or more users. The system receives a video from a user, where the video includes multiple video frames. The system extracts multiple key frames from the video and generates a visual representation of the key frame. The system compares the visual representation of the key frame with a plurality of product visual signatures, where each visual signature identifies a product. Based on the comparison of the visual representation of the key frame and a product visual signature, the system determines whether the key frame contains the product identified by the visual signature of the product. To generate the plurality of product visual signatures, the system collects multiple training images comprising multiple of expert product images obtained from an expert product repository, each of which is associated with multiple product images obtained from multiple web resources.

    摘要: Methods, apparatus, systems, and software for implementing context adaptive video streaming using multiple streaming connections. Original video content is split into multiple bitstreams at a video streaming server and streamed to a video streaming client. Higher-importance video content, such as I-frames and the base layer for scalable video coder (SVC) content are streamed over a high-priority streaming connection, while lower-importance video content is streamed over a low-priority streaming connection. The high-priority streaming connection may employ a reliable connection protocol such as TCP protocol, while the lower-priority connection may employ UDP or a modified TCP protocol under which some portions of the bitstream may be dropped. Cross-layer context adaptive streaming may be implemented under which context data such as network context and video application context information may be considered to adjust parameters associated with implement one or more streaming connections.
