ABSTRACT
The streaming media technology is a transmission technology that can provides the
continuous video and audio information compressed on the server for the client
watching and listening without the compressed file being fully downloaded. But the
capacity of such multimedia file is still so large that the interruption of transmission can
be caused when the network is busy. Improving the video and audio compression rate as
far as possible to get a smaller amount of data with a high quality of audio and video has
become a hot topic in the contemporary course of information construction.
Based on the H.264/AVC video compression standard, compress and decompress
video data based on RNS (remainder system). Gives the concrete implementation plan,
and demonstrates the feasibility of the implementation scheme and the analysis of
advantages and disadvantages as a result, RNS for further research on the application of
streaming media research laid the foundation. RNS system can convert large digital
integer to less integer, not only can reduce the system to deal with data bits, but RNS’s
parallel and no carry features will increase the speed processing. By choosing the
appropriate modules, without changing the H.264/AVC original structure, realizing data
compressed and decompressed. In this paper, puting forward two solutions: one is
compressing H.264/AVC entropy coding based on RNS, by adding a tag distinguish
between data, then packaging data into NAL layer. Another is compressing original
image based on RNS directly, obtaining RNS format data block, then entropy coding it,
packaging data into NAL layer. Thesse can compress data, but first solution increases
the data redundancy and the distinguish marks are easy to be mistakenly extracted into
data, the second compress original image based on RNS directly and entropy coded data
package for tranmission. In this paper, the RNS applicated in streaming media of
innovation lies in: (1) Analysis the data transmission process H.264/AVC standard,
using RNS compress the binary data stream, greatly reduce the needed number of bits.
(2) RNS (Remainder system )transmiss the compressed data on subchannel, ensure the
security of data information. At home and abroad at present, the RNS applicated in
streaming media has not been reported.
