Unequal error protection using LT codes and block duplication.
Luby Transform (LT) codes are powerful packet erasure codes with low encoding and decoding complexity. We provide a simple method to improve the bit error rate performance of LT codes. Moreover, we exploit our method ...
Robust live unicast video streaming with rateless codes.
We consider live unicast video streaming over a packet erasure channel. To protect the transmitted data, previous solutions use forward error correction (FEC), where the channel code rate is fixed in advance according to ...
Error-resilient packet switched H.264 mobile video telephony with LT coding and reference picture selection.
Packet switched video telephony over wireless networks for hand-held devices requires low-delay, low-complexity error control mechanisms to deal with packet loss. We present an efficient solution for 3G networks based ...
Practical channel-adaptive video streaming with fountain codes.
Video streaming is sensitive to packet loss, which can severely damage the quality of the received video. Video communication systems that rely on application-layer forward error correction (FEC) to combat packet loss ...
Video multicast using unequal error protection with Luby Transform codes.
In a recent work, we proposed a method for unequal error protection with Luby Transform codes and showed that it achieves lower bit error rates than a state of the art technique when the information symbols are partitioned ...
Optimal packet loss protection of progressively compressed 3D meshes
We consider a state of the art system that uses layered source coding and forward error correction with Reed- Solomon codes to efficiently transmit 3D meshes over lossy packet networks. Given a transmission bit budget, ...
