Abstract

We propose a new video homogeneous transcoding architecture DCT-based which relies on both quality and temporal reduction techniques. The frame layer control is driven by a new indicator, the jerkiness, which represents the user perception of the movement which affects a video stream. The proposed transcoder can meet the constraints of a real-time communication and it has been extensively tested under different conditions
