摘要： A request to retrieve data from a client device is intercepted by a video detector. The video detector determines if the request is for retrieving a video file. If the request is for a video file, and the video file is deemed to be transcoded to be displayed on the client device, the video detector forwards the request to a video optimizer along with encoding parameters. Encoding parameters are selected by the video detector based on properties of the client device, networks accessible by the client device, conditions of those networks, properties of the requested video and the type of video requested. The encoding parameters also include a file format type to which the requested video is to be transcoded.
摘要翻译：从客户端设备检索数据的请求被视频检测器截取。视频检测器确定该请求是否用于检索视频文件。如果请求是用于视频文件，并且视频文件被认为被转码以在客户端设备上显示，则视频检测器将该请求与编码参数一起转发到视频优化器。编码参数由视频检测器根据客户端设备的属性，可由客户端设备访问的网络，这些网络的条件，请求的视频的属性以及所请求的视频的类型来选择。编码参数还包括要被转码到所请求的视频的文件格式类型。

摘要： A system and a method are disclosed for identifying video files on a webpage and streaming video files to a client device. A server receives browsing data including uniform resource locator for a webpage and identifies missing videos on the webpage. The server identifies a source file for the missing videos including identifying a location for each missing video. The server retrieves a thumbnail for each missing video and provides it to a client device. Additionally, the server transcodes the video file responsive to a user input provided by a user. The transcoded video is streamed to the client device.

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.

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.
摘要翻译：混合位图模式视频编码系统以优化的编码性能对多个视频帧进行编码和解码。编码系统对视频帧进行过滤以确定适当的编码模式。响应于要以位图模式编码的视频帧，编码系统生成视频帧的位图和DCT型数据。视频帧的位图数据被无损编码，以保持视频帧的高质量。视频帧的DCT型数据被压缩编码。位图模式编码使得编码系统能够灵活地编码视频帧数据的一部分无损，并编码剩余的帧数据有损耗。因此，帧的无损编码提供帧的重要数据的高质量，并且同时在帧的较少重要数据上保持高压缩比。
