3D display requires a high-resolution, high-pixel playing system. This paper studies the video playback with single frame resolution of 16K × 8K . The bandwidth of display exceeds the current video display capability of 8K × 4K resolution. On the one hand, an appropriate system architecture needs to be built on the existing hardware level. 16 liquid crystal displays (LCDs) are used in this paper, with resolution of each LCD is 4K × 2K and size is 15.6 inches. Constituting a video display terminal array of 4 × 4 ,which the resolution is 16K × 8K . And a single-layer architecture with a fully decode is used. Decoding 16 channels of 4K signals on one host with i7-6800K and two video cards with NVS810 (both with 25GBps memory bandwidth) and deliver signals through 16 DP interfaces in parallel. On the other hand, under this architecture, running load of CPU and GPU, bus bandwidth and scheduling of dynamic storage capacity impose higher requirements on the encoding and decoding of video data. Comparative research between MPEG series and H.26X series coding standard has carried out in this paper. An inter-frame-based forward prediction (BFP) method is proposed. Finally, in the Win7 system, using mpeg-2 encoding standard, and decoding by using ffplay that achieves 16K video with 15Fps smooth playback. The effectiveness of the proposed method is verified. The proposed BFP method further reduces the decoding complexity of CPU.
