G06F 15/16

US Classification:

709231, 709205, 709230, 386 68

Abstract:

A receiver driven approach for playback of remote content is described. One embodiment includes obtaining information concerning the content of the media file from the remote server, identifying a starting location within the media sequence, identifying byte ranges of the media file corresponding to media required to play the media sequence from the starting location, requesting the byte ranges required to play the media sequence from the starting location, buffering received bytes of information pending commencement of playback, playing back the buffered bytes of information, receiving a user instruction, identifying byte ranges of the media file corresponding to media required to play the media sequence in accordance with the user instruction, flushing previous byte range requests, and requesting the byte ranges required to play the media in accordance with the user instruction.

International Classification:

G06F 15/16

US Classification:

709231000

Abstract:

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.

International Classification:

G06F 15/16

US Classification:

709230000

Abstract:

A computer device selected as a media server is connected to a consumer electronic (CE) device over multiple media transfer channels. The multiple media transfer channels together with an improved media transfer protocol allow for efficient, real-time transfer of different types of digital media, in various combinations, for playing on the CE device. Each type of media is transferred over its own dedicated channel according to its individual data rate. The improved media transfer protocol allows the data to be transmitted in either an asynchronous mode or a synchronous stream or timestamp mode depending on whether synchronization is desired. A dedicated control channel allows for the transfer of control information from the CE device to the media server as well as for resynchronizing media position of the server upon a change in play mode of the corresponding media.

International Classification:

G06F 15/16

US Classification:

709231000

Abstract:

A remote user interface provides a full motion, full-color, dynamic interface with complex visuals without imposing heavy hardware requirements on a consumer electronics device. Instead, the hardware requirements are placed on another computer device that is designated as a media server. The media server generates the complex UI, encodes the UI into one or more compressed video frames, and transmits the compressed video frames to the CE device. The CE device plays the UI video as it would any other video. User inputs for interacting with the UI are transmitted and interpreted by the media server. The media server updates the UI images based on the interaction.

US Classification:

725134000, 725142000

Abstract:

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.
