Abstract
Abstract An apparatus, a method and a system to efficiently manipulate in the compressed domain, spatial and/or temporal scaling of matching pursuit-coded digital signals. These manipulations, referred to as transcoding, may take place at a transcoding proxy located at an origin server, in any intermediary along the transmission path from the origin server to the client device, and/or at the client device. The preferred embodiment focuses on a method to perform rate adaptation and spatio-temporal scaling of a video stream composed of 3-D atoms in order to serve a set of heterogeneous client devices (e.g., a high-end personal computer, a personal digital assistant and a wireless phone). The proposed method applies to 1-D atoms (decomposition of audio signals) and 2-D atoms (image decomposition).
