Wait. Blitter? I had a hard enough time with dither in audio, now this. Well, if you're not up to the more ionospheric parts of technobabble, the folks at the University of Vaasa, Finland define it thusly:
Blit /blit/ vt. 1. To copy a large array of bits from one part of a computer's memory to another part, particularly when the memory is being used to determine what is shown on a display screen. "The storage allocator picks through the table and copies the good parts up into high memory, and then blits it all back down again." See bitblt, BLT, dd, cat, blast, snarf. More generally, to perform some operation (such as toggling) on a large array of bits while moving them. 2. Sometimes all-capitalized as `BLIT': an early experimental bit-mapped terminal designed by Rob Pike at Bell Labs, later commercialized as the AT&T 5620. (The folk etymology from `Bell Labs Intelligent Terminal' is incorrect. Its creators liked to claim that "Blit" stood for the Bacon, Lettuce, and Interactive Tomato.) Then that secondary reference ("see bitblt"): Bitblt /bit'blit/ n. [from BLT, q.v.] 1. Any of a family of closely related algorithms for moving and copying rectangles of bits between main and display memory on a bit-mapped device, or between two areas of either main or display memory (the requirement to do the Right Thing in the case of overlapping source and destination rectangles is what makes BitBlt tricky). 2. Synonym for blit or BLT. Both uses are borderline techspeak. OK, it's large bit transfer which, when scaled badly, can cause moiré patterns, which is most of what that eye-test-like thing is all about. Video2000 narrows in on your problems at various levels of scaling. Then, at the end, it gives you a humongously thorough scoring based on a set of weightings that you need the online instructions to properly fathom. The only trouble, as has been mentioned in other reviews, is that it would be nice if the program just did it for you (some parts do, but not all), instead of all that hands-on comparison, where you could a) err or b) lie like a Trojan. I did a little of both, and I'm sure it must have affected the results. Test Descriptions 1. Quality tests - evaluate the quality of your system in the following areas: scaling, color space conversion, de-interlacing and tearing during softDVD playback. 2. Performance Tests - are used to determine the performance of BLT-operations, memory transfers and softDVD playback.
