Report from Digital Video Broadcasting
One of the inherent problems with setting standards for digital television (TV) is that it involves freezing the choice of technologies at a specific point in time. Some promising technologies may have to be excluded because they are immature or not yet proven, while others are simply too demanding (e.g., in terms of processing power or memory requirements) to be included in mass-market products. A few years later, these “promising” technologies may have become commonplace, but consumers would not be happy throwing away millions of “perfectly good” TV sets if the broadcasters decided to replace the “old” standard for digital TV with a “new and better” standard. One solution to this dilemma is to ensure that any new standard is backward-compatible with the previous standard, as typified by the addition of color to monochrome TV. However, the requirement of backward-compatibility is a very severe constraint on the performance of new standards
