A way of combining two images. How the mixing is performed is provided by the alpha channel. The little box that appears over the left-hand shoulder of a news anchor is put there by an alpha mixer.
Wherever the pixels of the little box appear in the frame buffer, an alpha number of “1” is put in the alpha channel. Wherever they don’t appear, an alpha number of “0” is placed. When the alpha mixer sees a “1” coming from the alpha channel, it displays the little box. Whenever it sees a “0,” it displays the news anchor. Of course, it doesn’t matter if a “1” or a “0” is used, but you get the point.

Absolute time code (ATC) is generally recorded in the subcode or control track region of any digital tape. This is the code that digital tape machines use to locate specific points on a tape for autolocation or other functions. In some machines, it is even used to synchronize the tape to other equipment. ATC is precisely accurate and usually conforms to the IEC standard which is easily converted to the more commercially used SMPTE time code. Unlike SMPTE, ATC always begins at zero at the beginning of a digital tape and increments one frame at a time until recording stops. Some DAT machines have the ability to function without ATC on a tape while others simply will not play a tape without it. These days, almost all machines record it automatically so it will always be on every tape.

Graphic accelerators function like application-specific microprocessors whose purpose is to work in conjunction with a PC’s host microprocessor to display graphics. In general, graphic accelerators control frame memory, color processing, resolution, and display speed. With the advent of the high-speed local buses and higher clock rates, accelerators operate on 32-, 64-, and 128-bit pixel data.

a) The time required to receive valid data from a memory device following a read signal. b) This is the time it takes from when a disk command is sent until the disk reaches the data sector requested. Access time is a combination of latency, seek time, and the time it takes for the command to be issued. Access time is important in data intensive situations like hard disk recording, multimedia playback, and digital video applications.
Lower access times are better. Keeping your drives in good shape with periodic de-fragging, etc. will ensure that your drive is providing the fastest access times it can.
