The HD Puzzle In 2002, two different consortiums began to pave the way for a high-definition standard. HDTVs were a rarity at the time, but they wouldn’t be for long; unlike the initial experiments with high-definition broadcast technology in the 1970s and 1980s, which petered out after disputes between different lobbying firms and the underlying difficulty with broadcasting an HD signal, the new HDTV standards were fit for mass production; sets capable of high-definition images had been available on the consumer market for several years. With a set aspect ratio (16:9, influenced chiefly by the 1.85:1 spherical aspect ratio of theatrical films) and two different sets of “HD” resolution (1280 x 720 and 1920 x 1080), the stage was set for some kind of delivery format to be developed. On each consortium’s mind was the knowledge that’s arguably not too far out of mind for anyone in the technology industry: If we don’t do it, someone else will, soon. Upping the challenge was the imperative not to go too far astray of what the market would accept for a physical delivery system. DVD’s introduction had gone off fairly smoothly, owing to a coordinated effort by the DVD Forum (one of the two consortiums covered here); however, memories of the VHS-Betamax format war were still fresh enough to inspire caution when it came to designing a new A/V format. In addition, the smoothness of the DVD launch, and the degree of its success, presented its own limitation: customers were familiar with the DVD’s size and appearance, which was physically very similar to the size and appearance of a CD. Form factor was relevant here; the LaserDisc was a technologically superior option to VHS at the time of its release, and arguably superior to DVD in its initial days (owing to no compression being needed for LaserDisc video). Expense did the LaserDisc format in, but it’s hard to imagine that the physical size of the discs - so large as to be unwieldy to transport over any decent stretch - didn’t play a role in the format’s demise, too.
