eMeeting: the implementation of H.263 based embedded video communication

Video communication on the mobile devices will be very popular in the near future, but the limited resource of the current embedded processors can not support the complex video codec. In this paper we present the eMeeting prototype system which can implement the H.263 video encode and decode and bidirection communication on one XScale PXA255 general embedded processor. Experiment results show that the eMeeting system can achieve the frame rate up to 8fps under the circumstances that the encoding, decoding, network communication, video capturing and other modules are ongoing simultaneously
