摘要： The present disclosure relates to playback of video/audio streaming media data to provide a glitch-free experience. The system adapts the media stream to the user connection in order to provide the glitch-free experience. Stream selection can be made using a heuristics module located on the playback device that analyzes various aspects of the playback to make intelligent decisions about which media stream to download from a network.

摘要： Media streaming with smooth fast-forward and rewind is disclosed. One embodiment receives a media stream encoded at a first bit rate over a network connection, and in response to an input to fast-forward or rewind the media stream, the media stream may be retrieved at a second bit rate, and rendered at the second bit rate for fast-forward or rewind playback. By receiving the media stream at multiple bit rates, a media stream may be rendered at increased forward or reverse speeds without dropping frames in the media stream.

摘要： The present disclosure relates to playback of video/audio streaming media data to provide a substantially glitch-free experience. The system adapts the media stream to the user connection in order to choose the most desirable stream to avoid glitches. For example, in the case where there is interference (e.g., a microwave being used near a wireless device), the quality of the media stream is lowered. In one embodiment, an index file is used to make logical decisions about which media stream to choose in order to minimize glitches. The index file can take different forms, but, generally, includes characteristics about the available media streams. Example characteristics include the bit rates of the media streams and quality information about the media streams.

摘要： Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.

摘要： The present disclosure relates to playback of video/audio streaming media data. The media stream is available from the network at multiple bit rates. When a seek operation is performed, a playback device requests a lower bit rate media stream in order to quickly fill a playback buffer so that playback can commence more readily. After a seek start-up period is complete, the playback device can return to downloading the media stream associated with higher bit rates in order to increase the quality of the playback.
