A High Speed Video/Audio Stream Splitter for 4K Digital-Cinema

This paper develops the requirements of a high speed video stream splitting device and introduces a suitable architecture. The device can generate ten streams from a 500 Mbps 4K-digital-cinema stream without any loss. 1,000 receiving clients can be supported by connecting the devices in a multistage manner. It will be a key device in achieving a digital-cinema-based theater network and creating a new cinema distribution environment. The prototype of the device is implemented and the basic performance is evaluated by experiments. The evaluation results clearly show that the device satisfies the requirements
