Traditional video streaming can be performed in two ways such as Video on Demand (VoD) and Live Video Streaming (LVS). In recent days, live video streaming in mobile devices has many issues such as buffering, delay, low bandwidth, screen resolution, limited computational energy, storage resources and connectivity loss. There arises a need that Video Streaming users must have the capability to deliver...
This work presents a new adaptive QoS oriented CAC scheme, proposed to limit the occurrence of hard IEEE 802.11 WLAN-UMTS handovers to mobiles using real time applications. This scheme is hybrid, based on the service class differentiation, the location in the heterogeneous infrastructure and a vertical handoff decision function as well. The results show that our policy achieves significant performance...
The scalable video coding (SVC) standard as an extension of H.264/AVC allows efficient, standard-based temporal, spatial, and quality scalability of video bit streams. Scalability of a video bit stream allows for media bit rate as well as for device capability adaptation. Moreover, adaptation of the bit rate of a video signal is a desirable key feature, if limitation in network resources, mostly characterized...
