    摘要: One embodiment of the invention includes a method for managing a streaming media service. The method includes receiving a request for a streaming media service from a client and the streaming media service includes a media service component. A service location manager is selected to which to provide the request from a plurality of service location managers. Additionally, a service provider is selected to which to assign the media service component from a plurality of service providers of a network. Furthermore, the service provider is informed of the assignment to perform the media service component. The service provider is caused to prepare to perform the streaming media service on streaming media. Moreover, information is used to determine whether to initiate a handoff of the streaming media service from the service provider to another service provider. If it is determined to initiate the handoff, the handoff is initiated.

    摘要: A method and system for encoding a video frame. The method includes grouping macroblocks of a video frame into a plurality of groups and determining a first encoding rate for at least one of the plurality of groups based on at least one quantization parameter value associated with the group. The method further includes determining a distortion value associated with the first encoding rate and determining a distortion reduction density value based on the distortion value and the first encoding rate. The method further includes accessing a rate budget associated with the frame and adjusting simultaneously a plurality of quantization parameter values associated with one or more of the plurality of groups.

    摘要: Methods and systems for overcoming the apparent loss of a data packet are described. Encoded second data can be accessed, where the second data is predictively encoded with reference to encoded first data. A data packet that includes at least a portion of the first encoded data can be sent to a downstream device. If the data packet was not properly received by the downstream device, the encoded second data can be adapted to make it decodable independent of the encoded first data.

    摘要: A method for enhancing transmission quality of streaming media. A first bandwidth for a first communication link and a second bandwidth for a second communication link of a network are determined. Provided the first bandwidth is greater than the second bandwidth, a first excess bandwidth is utilized to improve transmission quality in the first communication link, wherein said the excess bandwidth is related to a difference of the first bandwidth minus the second bandwidth. Provided the second bandwidth is greater than the first bandwidth, a second excess bandwidth is utilized to improve transmission quality in the second communication link, wherein the second excess bandwidth is related to a difference of the second bandwidth minus the first bandwidth.

    摘要: A graphics to video encoder is disclosed. The encoder comprises a client image constructor that receives client input and constructs client image frames based on the client input. A scene integrator is coupled to the client image constructor. The scene integrator accesses base image frames and integrates client image frames with base image frames to generate client scene frames. The graphics to video encoder also has coupled to the scene integrator a video encoder that encodes and outputs the client scene frames as a video bitstream.
