Title: Denis Vassilevich Parfenov: Innovator in Acoustic Echo Control and Video Transcoding
Introduction
Denis Vassilevich Parfenov is a prominent inventor based in Moscow, Russia. He has made significant contributions to the fields of acoustic echo control and video transcoding. With a total of 6 patents to his name, Parfenov continues to push the boundaries of technology through his innovative ideas.
Latest Patents
One of Parfenov's latest patents is focused on time-domain acoustic echo control. This invention involves an acoustic echo control (AEC) module that receives both outgoing and incoming signals. The AEC module utilizes a delay estimation block to estimate echo delay in the time domain using adaptive filtering techniques. This allows for the alignment of incoming signal samples with the corresponding outgoing signal samples, effectively suppressing acoustic echo and adding comfort noise to enhance the incoming signal.
Another notable patent is related to intra-mode prediction for a video transcoder. This technology converts an encoded input video bit-stream with one spatial resolution into an output video bit-stream with a lower spatial resolution. By utilizing learned statistics of intra-mode transcoding, the transcoder can efficiently select appropriate intra modes without performing exhaustive searches, thereby reducing computational complexity and processor load.
