摘要： A system and a method are disclosed for transcoding video files on a server such that they can be streamed to a client device in substantially real-time. The server receives a video file a uses a prediction algorithm to predict each video frame's size based on encoding and streaming parameters associated with the input file and an output stream and transcoding each video frame. If a transcoded frame is too large, it is compressed further, if it is too small, the video file is padded. As such, each video frame transcoded or padded until the encoded frame is the same size as a predicted size. The transcoded frames are streamed to a client device to enable the client to device to playback the video after requesting it from the server.

摘要： A hybrid bitmap-mode video coding system encodes and decodes a plurality of video frames with optimized coding performance. The coding system filters a video frame to determine an appropriate encoding mode. In response to the video frame to be encoded in bitmap-mode, the coding system generates a bitmap and DCT-type data of the video frame. The bitmap data of the video frame are encoded losslessly to keep the high quality of the video frame. The DCT-type data of the video frame are encoded with compression. The bitmap-mode encoding enables the coding system to flexibly encode part of a video frame data lossless and encode the rest of the frame data lossy. As such, the lossless encoding of the frame provides high quality of important data of the frame, and at the same time maintains high compression ratio on less important data of the frame.

摘要： A network-based video encoding and decoding system encodes and decodes remotely displayed user application data on a centralized desktop computer. Remotely displayed user application data are screen captures of a browsing application run by the centralized desktop computer on user's behalf. The encoding system optimizes its encoding performance using back channel information which includes real time network capacity information and decoder feedback. The encoding system consults a back channel information manager to dynamically adjust encoding parameters. Based on the real time network capacity information received, the encoding system adjusts its capturing sampling rate. Based on encoding errors identified by the decoding system, the encoding system selectively re-send previously encoded frames/blocks, or send intra frames on demand to allow the decoding system to correct encoding errors. In response to encoding customization requests from the decoding system, the encoding system adjusts its encoding parameters to meet such requests.

摘要： A video optimizer receives a request to optimize a video, wherein the request includes optimization parameters and a uniform resource locator (URL) of the video. The video optimizer retrieves the video from an origin server and transcodes the video based on optimization parameters. The video optimizer load balances several transcoding sessions over one or more servers and tracks each session based on session identifications (IDs). Additionally, the video optimizer tracks each session to determine when a server is at or near capacity to prevent an overflow situation. The video optimizer is also enabled to stitch together two or more transcoding sessions in the event of a seek operation by a user during video playback. The video optimizer streams the video to the client device, enabling the client device to stream videos in substantially real-time after requesting the video.
