We propose and evaluate an extension to the Application-Layer FEC (AL-FEC) codes introduced by the Pro-MPEG Forum in its Code of Practice 3 r2 (Pro-MPEG COP3 codes), consisting in allowing the use of a number of matrices of dissimilar size per FEC block. So, unequal protection of the data packets in the video stream is enabled, since dissimilar code rates can be applied to different groups of data...
Lately, several algorithms have been proposed to automatically estimate the quality of video sequences, even some have been included in international standards. However, the majority only provide high performance under particular conditions and with certain types of degradations. Therefore, some proposals have been presented setting out the combination of various quality metrics to improve the performance...
We present an adaptive unequal error protection (UEP) strategy built on the 1-D interleaved parity Application Layer Forward Error Correction (AL-FEC) code for protecting the transmission of stereoscopic 3D video content encoded with Multiview Video Coding (MVC) through IP-based networks. Our scheme targets the minimization of quality degradation produced by packet losses during video transmission...
