Abstract: Network bandwidth is one of the bottlenecks of the Web cameras performance. So we proposed an approach of Web camera based on MPEG4. This paper introduces the design of Web cameras hardware and software. With PNX1301 chip, an applicable Web camera was implemented. Then the design and implementation of the PCI arbiter was given in detail.

Key words: MPEG4, compress, camera, arbiter
