Methods and apparatus for efficient distribution of image data / 2504102 Compressed hierarchical representation, which is used to reconstruct a "visually lossless" version of image data, is stored at a server. The compressed hierarchical representation is decomposed from the image data using a wavelet transform with floating point kernels, to generate coefficients. The server also stores residual data that permit reconstructing the full fidelity version of the image data from the visually lossless version. The client requests compressed coefficients to reconstruct a visually lossless version of portions of the image data, and the server transfers compressed coefficients specified in the request. To generate a full fidelity image, the client upgrades the visually lossless version of the image to a full fidelity image using the residual data. |

The procedure entails exchanging requests and responses, but the multimedia channel is selected or reported to the multimedia server. The user terminal transmits a channel-specific rendering request for the required multimedia channel to the multimedia server; during subsequent channel switching, the terminal simply transmits the new channel-specific request for a new channel to the multimedia server during the current session and reuses the matched transport parameters of the channel-transparent establishment procedure. |
