摘要： A method for performing a soft-handoff in a mobile streaming media system, and a method for performing a hard-handoff in a mobile streaming media system are is disclosed. In the soft-handoff embodiment, the present invention detects that a channel quality between a mobile client and a first base station remains above a drop threshold and that a channel quality between the mobile client and a second base station increases from below to above an add threshold. The present embodiment then sends a first multiple description bitstream from the first base station to the mobile client and sends a complementary second multiple description bitstream from the second base station to the mobile client. This method thereby provides improved utilization of wireless bandwidth during soft-handoffs, in contrast to conventional systems where the same bitstream is transmitted from each base station. In both the cases of soft-handoffs and hard-handoffs, when a mobile client enters a cell whose base station has no free capacity, the base station may prevent call dropping by reducing the number of descriptions being served to the existing clients and thereby providing capacity (at least one description) for the new client. These methods provide improved utilization of wireless bandwidth during soft-handoffs, and reduced probability of service disruption during both soft-handoffs and hard-handoffs.

摘要： A method and system for streaming media data to a fixed client and/or a mobile client. In one method embodiment, the present invention recites encoding media data to be streamed to a client into a first multiple description bitstream and into a second multiple description bitstream. The present method then determines the appropriate plurality of servers from a network of servers onto which the first and second multiple description bitstreams should be distributed. The present embodiment then recites distributing the first and second multiple description bitstreams to the appropriate plurality of servers positioned at intermediate nodes throughout a network such that a client is provided with access to the media data via a plurality of transmission paths. The present method is also well suited to redistribution of multiple description bitstreams to servers based upon time-varying demand, client movement, and the like.

摘要： A predictively-coded object-based picture signal representing a group of pictures is transcoded into a predictively-coded block-based picture signal representing the group of pictures by extracting a coded scene descriptor and coded object descriptors from the predictively-coded object-based picture signal. The coded scene descriptor is decoded to generate a scene descriptor. The coded object descriptors are partially decoded to generate respective partially-decoded object descriptors. The decoding extracts coding information that describes the predictive coding of the coded object descriptors. In response to the scene descriptor, a frame of a partially-encoded block-based picture signal representing one of the pictures as a current picture is generated from the partially-decoded object descriptors. Finally, a frame of the predictively-coded block-based picture signal representing the current picture is generated by predictively coding the partially-coded block-based picture signal to a uniform coding state in response to the coding information.

摘要： This disclosure provides a reverse play system that may be used with newer digital television and image standards. In particular, a compressed input including motion vectors is received, and the motion vectors are used to calculate closest match positions. The order of image frames is then reversed, and reverse motion vectors are calculated anew. In calculating new motion vectors, compression software performs motion search for each data block by first comparing a local neighborhood around the block with the closest match positions. If there is an exact match (between the data block and a closest match position), then an original motion vector is inverted and exactly re-used as a motion vector in reverse play. If there are several (non-exact) matches, the software weights every motion vector associated with overlap of the neighborhood and selects the motion vector corresponding to the largest overlap. Alternatively, if a sufficiently large local neighborhood is used, the software can select the motion vector corresponding to the smallest residual energy. If there is no overlap at all with any closest match position, then motion search is performed upon spatial domain data.
