In this work, we propose an optimal joint bit allocation framework in order to provide unequal error protection (UEP) for scalable video coding. In the proposed scheme, video sequence is coded based on scalable video coding (SVC) extension of the H.264/AVC standard. We generate different streams according to changing quantization parameters. Each stream divides into different sub-streams in terms...
In this work, we propose an unequal error protection (UEP) scheme for scalable video coding using low density parity check (LDPC) codes. LDPC codes are renowned for their near-capacity performance. In the proposed framework, a video sequence is coded based on scalable video coding (SVC) H.264/AVC standard document. We divide the SVC coded video stream into different sub-streams in terms of time and...
Reliably transporting captured video content over Wireless Sensor Networks (WSNs) poses several challenges due to the unique energy constraints presented by individual sensor nodes. The nature and amount of video content is another challenge that further complicates WSN data reliability problem. Motivated by the aforementioned factors, in this work, we propose an architecture that promises to enhance...
Network impairments such as delay and packet losses have severe impact on the presentation quality of many predictive video sources. Prior researches have shown efforts to develop packet loss resilient coding methods to overcome such impairments for real-time streaming applications. Interleaved source coding (ISC) is one of the error resilient coding methods, which is based on an optimum interleaving...
