1. A method, comprising:
- sending a burst transfer to a remote endpoint, the burst transfer including data extracted from a video stream and the burst transfer formatted for combining with the video stream at the remote endpoint to reconstruct a video frame on the remote endpoint;
wherein the burst transfer includes an initial transfer rate and a reduced subsequent transfer rate beginning at a transition instant.

Abstract
In one embodiment, a buffering server transfers a dynamic burst transfer of data encoded using an inter-coded compression technique. The dynamic burst transfer is timed so that an initial transfer rate is reduced to a remaining transfer rate at the same time or before a decoding endpoint joins a corresponding data stream. The decoding endpoint merges the video stream and the dynamic burst transfer to decode and quickly reconstruct a displayable video frame.

11. An apparatus, comprising:
-
one or more processors; and a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to; send a dynamic burst request to a remote network device; receive back a dynamic burst transfer that initially uses a first average transfer rate and then transitions to a second reduced average transfer rate at a predetermined transition time; send a join request to join a video stream; and combine the video stream and the dynamic burst transfer to output a continuous sequence of image frames for display on a display device. - View Dependent Claims (12, 13, 14)
