摘要： Systems and methods for providing variable trick-play mode playback of media content in accordance with embodiments of the invention are disclosed. A playback device stores images of the media content associated with presentation times and marker information for the media content that indicates the presentation time of moments of interest. When a trick-play mode is invoked, the playback device determines a presentation time of a next marker in the playback. The playback device determines whether the current presentation time of the playback is within a specified range of the presentation time of the next marker and adjusts the speed of the trick-play playback based on the determination. The next frame to present is determined based on the adjusted speed of the trick-play playback and displayed.

摘要： Systems and methods for encoding a plurality of alternative streams of video content using multiple encoders in accordance with embodiments of the invention are disclosed. An encoding system includes multiple encoders. Each of the encoders receives a source stream of video content that is divided into portions. Each of the encoders generates portions of the plurality of alternative streams from the portions of the source stream. The portions of the alternative streams generated by a particular encoder are stored in a container for the particular encoder. Each encoder also generates index information for the portion of the alternative stream generated by the encoder that is stored in a manifest for the encoder.

摘要： Systems and methods for sharing content between devices are disclosed. To request a shared piece of media content, a playback device generates and sends a request to content server. The playback device includes information in the request that indicates the playback capabilities of the device. The content server receives the request and determines the playback capabilities of the playback device from the information in the request. The content server then determines the assets that may be used by the playback device to obtain the media content and generates a top level index file for the playback device that includes information about the determined assets. The top level index file is then sent to the playback device that may then use the top level index file to obtain the media content using the indicated assets.

摘要： Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.
