Title: Dennis Clawson: Innovator in Digital Audio Technology
Introduction
Dennis Clawson is a notable inventor based in Seattle, WA, recognized for his contributions to digital audio technology. He has developed innovative methods to enhance the delivery of on-demand audio, addressing critical issues related to data loss during transmission.
Latest Patents
Clawson holds a patent for "Error mitigation and correction in the delivery of on demand audio." This patent describes a method and system designed to mitigate and compensate for the loss of digital audio data transmitted as a stream of packets to a client. The invention involves a server that compresses digital audio data corresponding to a digitized analog audio signal. The compressed data is divided into N frames of data per packet, and the server interleaves these frames to produce interleave packets. This interleaving minimizes the impact of any lost packets when the interleave packets are received, deinterleaved, and converted to an analog signal for playback. Lost frames are replaced using data from frames that are received, ensuring a seamless audio experience. Additionally, the frames can be scrambled at the server using a permutation function that depends on the packet number and a key value, with an inverse permutation function applied at the client to unscramble the frames.
