DSPs are already a chief means of grafting the impact of Moore's Law onto telecommunications capabilities. There are several varieties of DSL using varying hardware, modulation software, and compression techniques. Circuit that accepts digital signals and converts them to analog signals. A modem typically has such a circuit. A television network that transmits digital, as opposed to analogue, television signals.
Digital television enables interactivity and provides improved capacity and picture quality.
Video stored or transmitted in a digital format. Several digital video formats exist, but MPEG-2 is quickly becoming an industry standard. New standard for digital, full-length movies encoded on CDs. Aims to replace video cassettes, laser discs, CD-ROMs, and audio CDs. Another combination of technologies, may eventually increase the ROM version to 17 GB of storage capacity.
