System and method of streaming 3-D wireframe animations

摘要

Optimal resilience to errors in packetized streaming 3-D wireframe animation is achieved by partitioning the stream into layers and applying unequal error correction coding to each layer independently to maintain the same overall bitrate. The unequal error protection scheme for each of the layers combined with error concealment at the receiver achieves graceful degradation of streamed animation at higher packet loss rates than approaches that do not account for subjective parameters such as visual smoothness.

1. A method comprising:
processing, via a processor, parameters n, FR, Sp, and F of video data via a channel bitrate algorithm, wherein the parameters are located in a block-of-packets structure for each layer of a plurality of layers of video data, n is a number of lines in the block-of-packets structure, Sp is a number of columns in the block-of-packets structure, FR is a sequence frame rate, and F is a number of data frames in the block-of-packets structure for a respective layer of the plurality of layers, wherein the channel bitrate algorithm produces a bitrate value for each layer in the plurality of layers based on a product of n, FR, and Sp to yield a result, the result being divided by F, to yield bitrate values; and applying, via the processor, unequal error protection to a layer of the plurality of layers according to the bitrate values produced by the channel bitrate algorithm.
