Improved Detection for H.264 Encoded Video Sequences over Mobile Networks
Olıvia Némethová, Jacob Canadas Rodriguez, Markus Rupp · 2005
Real-time video conferencing or streaming over mobile network introduces a challenge to the endto-end design of the whole system. Due to the realtime character of these applications, there are no retransmissions possible at the transport layer and therefore any errors result in packet loss at the receiver. This article investigates error resilience methods, especially improvements of the detection granularity to minimize perceptual visual quality degradation at the receiver. Costs of the additional error resilience is evaluated and a combination of H.264 resilience features, improved error detection and error concealment is finally tested. 1
