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 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.
