In this paper, we propose a 4K digital cinema transmission over 1.2Gbps wireless LAN system. The proposed system employs the next generation wireless LAN system based on IEEE802.11ac specification. It reaches more than 33 meter propagation distance by using 80MHz of bandwidth on the 5GHz band. In this system, video data is compressed by JPEG 2000 with error resilience tools. These tools improve error performance against wireless channel, and enable very high throughput communication. Computer simulations are used to evaluate the bit error performance's influences to the video quality. Finally, we present RTL design results of the proposed wireless LAN system.
