We consider centralized wireless networks for users of video streaming services. If the network is congested, wireless channel resources can be insufficient to satisfy all user requests. In this case QoE with some users may heavily degrade (video playback may periodically interrupt due to rebuffering effect, or startup buffering can take an intolerably long time). These negative effects can be partly...
Evolved Multimedia Broadcast Multicast Service (eMBMS) is used for efficient content delivery to multiple users in Long Term Evolution (LTE) networks. In most cases eMBMS allows to use radio resources more efficiently comparing to unicast content delivery. It will be shown in this paper how many users should receive the same content to activate broadcasting instead of unicast delivery.
This paper disscuses latency-constrained video transmission over high-speed wireless personal area networks. Low-power single-layer video compression is proposed as an alternative to others video processing approaches. End-to-end distortion and end-to end latency in video transmission system are analyzed. A near-optimal video source rate control based on MINMAX quality criteria is introduced. Practical...
