Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) offers high data rate capabilities to mobile users, and, operators are trying to deliver a true mobile broadband experience over LTE networks. Mobile TV and Video on Demand (VoD) are expected to be the main revenue generators in the near future and efficient video streaming over wireless is the key to enabling this. In this paper, we are proposing an efficient adaptation scheme for Scalable Video Coding (SVC) transport over LTE networks and investigate the benefits of this scheme for video streaming over LTE networks. Video streaming over LTE networks is analyzed using a 3GPP compliant LTE simulator using H.264 and SVC video traces. Analysis is done using real time use cases of mobile video streaming. Different parameters like throughput, packet loss ratio, delay, and jitter are compared with H.264 single layer video for unicast and multicast scenarios using different kinds of scalabilities. Results show that considerable packet loss reduction and throughput savings (18 to 30%) with acceptable video quality are achieved with proposed scheme based on SVC compared to H.264. Advantages of proposed scheme for LTE networks are evident from the simulation results.
