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 for communicating video data associated with content across a network are disclosed. A server partitions the content into a plurality of tiles where each tile includes a subset of the content and index data describing a relationship between a tile and one or more adjacent tiles. Each tile is then encoded as a video frame, for example each tile is encoded according to the H.264 standard. The plurality of tiles are then transmitted to a client which combines the plurality of tiles using the index data to locally recreate the content. The client associates a predetermined viewport tile with a client viewport representing the area of the content that is visible in a client display device to allow viewing of the content while tiles not associated with the client viewport are cached to expedite subsequent retrieval.

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.
摘要翻译：视频优化器接收优化视频的请求，其中请求包括视频的优化参数和统一资源定位符（URL）。视频优化器从原始服务器检索视频，并根据优化参数对视频进行转码。视频优化器通过一个或多个服务器负载平衡多个代码转换会话，并根据会话标识（ID）跟踪每个会话。此外，视频优化器跟踪每个会话以确定服务器何时处于或接近能力以防止溢出情况。视频优化器还可以在视频播放期间在用户进行搜索操作的情况下将两个或更多个代码转换会话拼接在一起。视频优化器将视频流传输到客户端设备，使客户端设备在请求视频后能够基本上实时流式传输视频。

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 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.
