Unequal Loss Protection for Data-partitioned Mpeg-4 Video over the Packet Erasure Networks

چکیده
In this paper, we present a novel unequal loss protection (ULP) algorithm for robustly transporting datapartitioned MPEG-4 video over the packet erasure networks. To minimize the overall distortion in a frame, a redundancydistortion optimization scheme is developed by optimally assigning the given amount of forward error correction (FEC) codes between motion parts and texture parts according to the network status. Experiment results show that this proposed scheme provides high robustness and achieves graceful degradation of video quality over a wide range of packet loss rate.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملAn Unequal Error Protection in ROI for H.264
Compressed video sequences are very vulnerable to channel disturbances especially when they are transmitted over the packet erasure channels. The transmission errors 1 caused by packet loss not only corrupt the current decoded frame, but also cause the error propagation to the succeeding frames which degrades the quality of services. Therefore, it is considerably important to develop the error ...

In this paper, we evaluate the packet loss resilience of the recently developed MPEG-4 Fine-Granular-Scalability (FGS) video coding method for Internet streaming applications. Since unrecoverable packet losses are very common over the Internet, the focus of this study is to determine how robust the MPEG-4 FGS coding tool is under unrecoverable IP packet-losses over a wide range of connection qu...

متن کاملDependency-Aware Unequal Erasure Protection Codes
Classical unequal erasure protection schemes split the data to be protected into classes which are encoded independently. The unequal protection scheme presented in this document is based on an erasure code which encodes all the data together according to the existing dependencies. A simple algorithm generates dynamically the generator matrix of the erasure code according to the structure of th...
