Scalable video broadcasting trials in 4G cellular deployments

摘要

Future LTE mobile communication systems provide for the first time low delay and high data rate and access over wireless. This enables transmission of new multimedia applications with high quality. H.264/Scalable Video Coding delivers high-quality video content with a scalable data rate, which perfectly matches with the LTE technology. The combination of H.264/SVC and LTE enables in a cross-layer approach with unequal error protection a robust transmission of HDTV multimedia content over the air. First field trial results in the cellular downlink of a LTE system show that scalable video broadcasting is a promising approach with a robust performance delivering high quality video transmission to mobile users.
