Error-resilient video transcoding for robust internetwork communications using GPRS
A novel fully comprehensive mobile video communications system is proposed in this paper. This system exploits the useful rate management features of the video transcoders and combines them with error resilience for transmissions of coded video streams over general packet radio service (GPRS) mobileaccess networks. The error-resilient video transcoding operation takes place at a centralized poi...
متن کاملTranscoding-Based Error-Resilient Video Adaptation for 3G Wireless Networks
Transcoding is an effective method to provide video adaptation for heterogeneous internetwork video access and communication environments, which require the tailoring (i.e., repurposing) of coded video properties to channel conditions, terminal capabilities, and user preferences. This paper presents a video transcoding system that is capable of applying a suite of error resilience tools on the ...
متن کاملError Resilient Video Communications in Wireless Atm
A combined source coding, channel coding, and packetization scheme is proposed for high performance video communications over wireless ATM. Three-dimensional signi cance-linked connected component analysis (3DSLCCA) source codec signi cantly reduces error propagations while maintaining high coding e ciency. Channel coding is implemented by using Reed-Solomon codes for both within-cell and inter...
متن کاملContent-aware error-resilient transcoding using prioritized intra-refresh for video streaming
Transmitting video data over wireless networks can be very unreliable due to packet-loss, leading to serious video quality degradation which is annoying to human perception. The lost packets not only affect the quality of current frame, but also lead to error propagation to subsequent frames due to motion-compensated prediction techniques used in standard video codecs. Adding error-resilience t...
متن کاملRobust error-resilient approach for MPEG video transmission over Internet
In network delivery of compressed video, packets may be lost if the channel is unreliable. Such losses tend to occur in burst. In this paper, we develop an error resilient video encoding approach to help error concealment at the decoder. We introduce a new block shuffling scheme to isolate erroneous blocks caused by packet losses. And we apply data hiding to add additional protection for motion...
