FPGA Implementation of High Performance and Low Power VOD Server

Video play has become a popular entertainment as network capacities have been improved. To lower the power of the video stream server to meet the requirements of green computing and to save the bandwidth which helps to solve the bandwidth congestion problem, a novel hardware-based VOD server system is introduced. We design an architecture that is suitable for video stream transmission. We manage to complete a prototype system which is implemented in an FPGA board. In this paper, we describe the structure of the VOD system, the method of processing requests and the organization of large amounts of information. Besides, we propose a dynamic file chunking technique to implement real time playing. With it, users can interact with the system when playing a video. Index Terms—VOD, FPGA, architecture, low power.
