    Abstract: One embodiment of the present invention sets forth a technique for identifying and pre-buffering audio/video stream pairs. The method includes the steps of predictively identifying for pre-buffering at least one audio/video stream pair that may be selected for playback by a user subsequent to a currently playing audio/video stream pair, computing a first rate for pre-buffering an audio portion of the at least one audio/video stream pair and a second rate for pre-buffering a video portion of the at least one audio/video stream pair, downloading the audio portion at the first rate and downloading the video portion at the second rate, and storing the downloaded audio portion and the downloaded video portion in a content buffer.

    Abstract: One embodiment provides a technique for dynamically adjusting streaming media bit rates in response to user requests for accelerated playback. A user request to increase a playback speed at which the units of digital content are played back on a content player is received. Upon receiving the user request to increase the playback speed, while previously downloaded units of the digital content having a first bit rate are being output for display, and prior to downloading a next unit of digital content from a content server, embodiments determine that the increased playback speed cannot be maintained without buffer underrun if subsequent units of digital content are downloaded from the content server at the first bit rate. A second bit rate, lower than the first bit rate, is determined and the next unit of digital content is downloaded from the content server for playback at the second bit rate.

    Abstract: One embodiment of the present invention sets forth a technique for managing playback of digital content on two or more different playback devices. A playback device designated as a controller is associated with a playback device designated as a playback target. Association is implemented via a local network discovery protocol. The controller issues commands to the target, which then streams digital content directly from a content server. The controller is able to separately stream related digital content for independent, but synchronized playback. Server mediated operations, such as device activation and application installation, are advantageously enabled by explicit association between the controller and the target.
