In fact, they function in quite the opposite manner. Convergence, in a broader sense, has already amounted to many changes. Fiber optics were nowhere in sight, and packet-switching networks were just an idea. All content is, to a large extent, reducible to bits. Bandwidth is increasing and there is competition between bit delivery methods.
Bits are bits, and bandwidth is bandwidth.
It's all about the bits . Ten years ago, a common assumption was that 45 million bits per second were needed to obtain studio-quality television. Today, that level of performance is possible at 4 million bps. There is one fundamental reason for this profligate use of bandwidth. Even if you compress them by taking out the enormous redundancy that occurs within and between frames and by taking advantage of the characteristics of human vision, video as we know it still uses many more bits than a computer graphics database capable of synthesizing the same images.
