Dr. Rajesh Bhadada, Dr. K L Sharma . Sustainable Performance Bounds at Receivers for Contiguously Framed Server Streamed Video Data for VCR like Functions for On Line Video on Demand. International Conference on Electronics, Information and Communication Engineering. ICEICE, 1 (December 2011), 26-33.
Ideal online video on demand (VoD) system should make available any video at any time with smooth VCR like functions such as fast forward, fast backward during playback. Providing them by unicast streaming (dedicated channels) is expensive and ties up resources in networks causing blocks. Video data are bulky and need high bandwidth for real time playback in networked storage and playback environment. The resource blocking manifolds when multiple users go online. Sustainable performance can be attained by identifying conditions and bounds for networks, servers and the receiver equipment. Modern video data follows framed structures and makes use of relative coding. Data streaming and buffering has to support not merely simple linear playback but also non sequential users VCR like interactions. They were quite simple under electro-mechanical playback/storage technologies such as VCRs, cd/dvd players. Modern information networks use non-linear compression, non sequential storage, distributed data approaches and that too are coupled with random communication delays. Together they pose challenges against interactive VoD.
