Unequal Protection of Video Data According to Slice Relevance
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
In this paper, we devise a procedure that mimics the behavior of a progressive video stream starting from a non progressive one such as H.264/AVC encoded video. This allows one to unequally protect the video data in an ...
Efficient slice-aware H.264/AVC video transmission over time-driven priority networks
(John Wiley and Sons Ltd, 2014)
This paper proposes a multimedia streaming architecture that combines network and video technologies to handle video traffic over multi-hop access networks. In this context, resource overprovision typical of current quality ...
Image and video transmission: A comparison study of using unequal loss protection and multiple description coding
We present a performance comparison between multiple description coding (MDC) and unequal loss protection (ULP) as tools to deliver multimedia data to mobile users. Graceful-degradation encoding schemes are able to cope ...
Slice Sorting for Unequal Loss Protection of Video Streams
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
In this letter, we propose a novel unequal loss protection scheme, which allocates FEC codes to video slices according to their impact on the GOP distortion. This is evaluated taking the concealment procedure and the drift ...
Multiple Descriptions Based on Multirate Coding for JPEG 2000 and H.264/AVC
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
Multiple description coding (MDC) makes use of redundant representations of multimedia data to achieve resiliency. Descriptions should be generated so that the quality obtained when decoding a subset of them only depends ...
A Comparison Between ULP and MDC With Many Descriptions for Image Transmission
In this letter, we present a performance comparison between multiple description coding (MDC) and unequal loss protection (ULP) for progressive image transmission over lossy packet networks. Two optimization criteria are ...
