Abstract :
The design of a platform based video streaming server using the Xilinx microblaze processor and a custom H.263 hardware compression core is presented. The design uses a novel data structure to store the input images in external memory, allowing the H.263 core and the associated camera interface to utilise the external memory bandwidth more efficiently. The finished system is capable of encoding and streaming, using the real-time transport protocol, Dl sized video, at 30 frames per second in a Spartan-3 1500 FPGA device.
