Robust and scalable matching pursuits video transmission using the Bluetooth air interface standard
This paper introduces an error resilient implementation of the matching pursuits algorithm for video coding. The video bitstream is transmitted using a simulation of the Bluetooth air interface standard, which recommends ARQ as a means of overcoming channel errors in the data packets. This approach may be unsuitable for real time and broadcast applications. Therefore, a modified receiver is proposed in this paper, which does not request the retransmission of erroneous packets, but instead passes them to the video decoder to exploit error resilience. This strategy is shown to be superior to a standard compliant system if ARQ cannot be applied. The work confirms that wireless communication standards should support a transparent mode for video applications
