Error Resilient Multipath Video Delivery on Wireless Overlay Networks

Error Resilient Video Transmission over Wireless Networks

This report proposes a general architecture for error resilient video transmission over mobile wireless networks. Radio link layer, UDP Lite, and error control layer are combined to deal with high error rate in wireless environments. Both sender and receiver algorithms are given. An adaptive algorithm is further presented to automatically adjust parity data length in error control. The performa...

Error Resilient and Robust Overlay Networks

Error Resilient Interactive Video Streaming Over Wireless Networks

This paper presents an efficient approach for supporting wireless video full interactive services. One of the main goals of wireless video multicast services is to provide priority including dedicated bandwidth, controlled jitter (required by some real-time and interactive traffic), and improved loss characteristics. The proposed method is based on storing multiple differently encoded versions ...

Error Resilient Transmission of Video Streaming over Wireless Mobile Networks

THE third generation of mobile systems brought higher data rates that allow for provisioning of multimedia services containing also video. The real-time services like video call, conferencing, and streaming are particularly challenging for mobile communication systems due to the wireless channel quality variations. The mechanism for video compression utilizes a hybrid of temporal and spatial pr...

Transcoding-Based Error-Resilient Video Adaptation for 3G Wireless Networks

Transcoding is an effective method to provide video adaptation for heterogeneous internetwork video access and communication environments, which require the tailoring (i.e., repurposing) of coded video properties to channel conditions, terminal capabilities, and user preferences. This paper presents a video transcoding system that is capable of applying a suite of error resilience tools on the ...
