| Abstract | Digital Cinema (DC) electronic distribution requires networks with high available bandwidth. In this paper, we propose a system that adopts a frequency multiplex of DVB-T signals to deliver JPEG 2000 video over wireless channels characterized by multipath. The objective of this paper is to present a transmission scheme that, by optimizing transmission over DVB-T channel, provides content distributor and/or end users with the possibility to obtain a very high quality video stream. The source coded video is first downsampled to a video quality still at an high level, and then compressed with parameters reflecting the specifications for DC. The stream is thus split and encapsulated into MPEG-2 TS packets. A proper strategy of substream multiplexing and composition is presented, which may reduce the residual error effects and bandwidth requirements. Optionally, a Forward Error Correction layer can be applied to further enhance transmission robustness. At the receiver side a proper demultiplexing and decompression is performed. Eventually, we will also present simulated results in terms of objective video quality vs. channel SNR and multipath conditions. |
