On Associating SVC and DVB-T2 for Video Broadcasting
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 7
Abstract
DVB-T2 is offering a new way for broadcasting value-added services, like HDTV and 3D TV, to either fix or mobile end users. DVB-T2 brings a new flexibility in services broadcasting with an increased transfer capacity of 50%, in contrast with the first generation of the DVB-T standard. On the other hand, SVC video coding is an emerging technique that uses scalability to encode video content in a hierarchical video streams (i.e. layers). Indeed, the SVC supports three types of video scalability: spatial, temporal and quality; which allow handling user’s heterogeneity in term of capacity and bandwidth. To support SVC over DVB-T2 networks, associating the layering architecture of both technology, in order to tackle users mobility. This association allows mobile receivers with good physical channel to decode all the SVC layers and benefit from high video quality. Meanwhile, users with worst channel condition can at least decode the base layer and benefit from acceptable video quality.
