摘要： An image display system includes a web server with web pages containing images in a first format. The first format includes a Graphics Interchange Format (GIF), a Joint Photographics Experts Group (JPEG) format and/or a Motion Pictures Experts Group (MPEG) format. A distributed communications system is connected to the web server. A proxy server is connected to the distributed communications system. The proxy server decompresses the first format images. The proxy server converts the first format images to a second format that includes either JPEG or MPEG image formats. The proxy server compresses the second format iamges. A set top box that is connected to the proxy server contains either hardwired circuits or hardware acceleration for quickly decompressing the second format images and for generating image frames. A display that is connected to the set top box allows viewing of the image frames.
