Quality of Service Enhancement for Multimedia Applications Using Scalable Video Coding

Streaming of media data is the most rapid-growth network service. On the other end there are vast numbers of application users to access the service. Supporting end-to-end Quality of Service (QoS) is the real-time issue for the application administrators. For an application, safeguarding the QoS in streaming the video records from source to destination in a network is must. Representing client needs and reaching their desire for video service through application is essential as the clients expect greater administration quality. Henceforth the applications ought to be constantly reachable and responded at a quicker rate. This paper presents an approach for enhancing Quality of Service (QoS) over the network for streaming the media data in two phases: Firstly, Considering the type of resolution of the device to which the application user is connected. Secondly, the transmission capacity the client is associated. To preserve the Quality of Experience (QoE), the proposed solution aims at streaming only the file format the client device supports, taking into account the type of resolution the client device is having (this prevents the client to manually select the different file formats eg: Youtube). To achieve the streaming of different file formats Scalable Video Coding (SVC) technique is used which increases the QoS by preventing the packet loss and delay in the service. SVC is an expansion of (MPEG-4 AVC) video compression standard for video encoding. It is a standard that packs the video information which has the subsets (different formats) of video, this comprises of video designs (of various pixels). These are piled up in a single document and can be placed in the single server. Here we are decreasing the server overhead (different formats on different servers) by placing it on a single server and delivering the requested video recordings to the client at a faster rate. The experimental results shows that the application enables multiple devices to access the service at faster rate and accomplish with high quality video service without giving up the execution.
