Title :
Autosophy image compression for packet network television
Abstract :
Transmitting graphics or live television on the Internet or Information Superhighway will be very slow and expensive unless video compression is used to reduce the transmission bandwidth. There are three basic ways to transmit images and video. Conventional bit stream transmissions depend on very high speed channels, such as fiber optics. Lossy cosine transforms and motion compensation in the JPEG or MPEG-2 standards will reduce the bandwidth but at the expense of the image quality. The more the images are compressed, the worse the distortions become until the image quality becomes unacceptable. A new Autosophy information theory may now provide a third alternative. In the new information theory, “information” is dependent only on image content or “novelty” and “movement” within the images. Information is redefined as something not already known to the receiver. Everything the receiver already knows is redundant and need not be communicated. “Knowledge” is accumulated in tree networks that grow by themselves like data crystals. The result is a new kind of television in which the bandwidth is determined only by the image content or what is to be shown on the screen. Hardware parameters, such as image size, resolution or frame rates become irrelevant. Very high lossless image compression is achieved without sacrificing image quality. The transmission method is especially suitable for packet switching networks and provides optional encryption for network security. It can also be used to transmit still image graphics on the Internet or to store multimedia moving images in PCs
