    摘要： Systems and methods of providing enhanced digital media playback through application enhancement tracks are described. Application enhancement tracks are derived from the main content that they are associated with and are encoded to aid the performance of one or more functions related to the content, such as visual-search using a video application enhancement track, or trick-play track. In several embodiments, a method of decoding a media file for play back includes obtaining a media file containing compressed content and an accompanying application enhancement track which is a subset of the compressed content, playing back the compressed content, and decoding frames of the application enhancement track at a rate proportional to a visual-search speed and from a location determined by the portion of the compressed content most recently played back.

    摘要： Multimedia distribution systems are disclosed in which servers communicate with clients via audio, video, overlay and/or control channels. Information sent between the clients and servers on the audio, video and/or overlay channels includes timestamps. The timestamps coordinate the queuing and processing of information received by the client. Once information has been processed by the client, the client can report information concerning the timestamps associated with the processed information to the server. In one embodiment, the invention includes a server connected to a client via a network. In addition, at least one server is configured to communicate audio, video, overlay and control information with a client via separate audio, video, overlay and control channels, information transmitted on at least one of the audio, video and overlay channels includes time stamps, the client is configured to process the audio, video and overlay information for output to one or more rendering devices and the client is configured to transmit information concerning time stamps of processed information to the server via the control channel.

    摘要： Multimedia distribution systems are disclosed in which servers communicate with clients via audio, video, overlay and/or control channels. In many instances, the audio, video and/or overlay information is transcoded prior to transmission. In many embodiments, the servers and/or clients can be updated. In several embodiments, the updates can be performed in a manner that preserves the ability of all devices connected to a network to communication. One embodiment of the invention includes a server connected to a client via a network and at least one storage device containing audio, video and/or overlay information formatted in accordance with a first format. In addition, the client includes a storage device that stores information indicative of the audio, video and/or overlay formats that the client is capable of decoding and the server is configured to transmit audio, video, overlay and control information via separate audio, video and overlay and control channels.
