Satellite distribution provides a cost-efficient way to expand the coverage of mobile networks to rural areas. However, to become widely accepted by users and content providers, mobile satellite services need to provide a Quality of Experience (QoE) comparable to that of mobile video services provided in cellular networks. Mobile reception by satellite is characterized by shadowing periods where the...
Peak Signal-to-Noise Ratio (PSNR) is the simplest and most widely used objective video quality evaluation method. However, traditional PSNR calculations do not take packet loss into account thus giving an inaccurate representation of the video quality. Indeed, transmission packet losses may be the cause of visible destructive distortions, which can result in a progressive quality degradation due to...
The main challenge for provisioning of Mobile TV services is to overcome long burst errors as are often found in mobile reception conditions. Long time interleaving can be implemented by means of Application Layer FEC (AL-FEC) to increase the time diversity of the signal and thereby its robustness against burst errors. The main obstacle of long time interleaving for streaming services is the increase...
