From Wikipedia, the free encyclopedia. A value-added service (VAS) is a popular telecommunications industry term for non-core services, or in short, all services beyond standard voice calls and fax transmissions. However, it can be used in any service industry, for services available at little or no cost, to promote their primary business.
AVS, an acronym for Application Visualization System, is a high quality digital video format developed and maintained by Application Visualization System Inc. Based on the DVI (Digital Video Interactive) technology, it is mainly used as a post-production tool to edit and process video files. The AVS file is a binary file. It consists of two four-byte integers containing the x and y size of an image, followed by four byte tuples (representing alpha, red, green, and blue) with data for each of the pixel of an image. This AVS file is generally stored in the data subdirectory of an install directory.
