High quality replay of a streaming multimedia video segment on demand is provided. The multimedia segment may be transmitted as a stream by a server system and received by a client system over a fixed bandwidth communications path. The client system receives a base layer of the stream, decodes the base layer and displays the decoded base layer at a first quality level. The client system stores at least a portion of the base layer in a cache. When a request for replay service for the multimedia segment is received from a user, for high quality replay, the client system may receive at least one enhancement layer of the stream corresponding to the stored portion of the base layer. The client system may then read the stored portion of the base layer from the cache, decode the stored portion of the base layer and the at least one enhancement layer, and display the decoded base and enhancement layers at a second quality level, higher than the first quality level.

Method of providing replay on demand for streaming digital multimedia

A method and apparatus of improving the quality of graphic and/or audio information, such as a video clip, transmitted over a network is provided. In one particular embodiment, a network client requests multiple downloads of a video clip stored on the network server. In response to each request, the network server compresses the video clip and transmits the compressed data in a scalable bitstream. The video clip includes an audio channel which occupies a first portion of the available bandwidth, and a video channel which occupies a second portion of the available bandwidth. Upon receipt of each download, the network client stores the audio and video data in cache. The network client combines the data from each download in the cache prior to displaying the video clip in a web browser program. In each iteration of the download and caching process, the information for the audio and video channels increases, thus improving the resolution of the downloaded image and sound data, and thereby increasing the effective bandwidth of the network over which the video clip was transmitted.

Method and apparatus for increasing the effective bandwidth of video sequences transmitted over a network by using cached data

A method and apparatus of transmitting time critical messages over a network is provided. Data which has minimal bandwidth requirements, such as data packets utilized in applications such as twitch games, is received or generated in a network device. The data is classified as minimal bandwidth data and prioritized relative to other data for transmission before the other data. The data is then transmitted by the device to a second device on the network before the other data is transmitted.

Method and apparatus for increasing the effective bandwidth of video

A method and apparatus for exclusively activating pixels in an active area of a computer display when a computer system is operating in a power management mode. In one embodiment, the pixels within the active area of the display are exclusively activated by providing less power to the pixels outside of the active area of the display.
