Chapter 3: Bitcasting
When television is digital, it will have many new bits – the ones that tell you about the others. These bits may be simple headers that tell you about resolution, scan rate, and aspect ratio, so that your TV can process and display the signal to its fullest capacity … The bits may be the control data for a knob that allows you to change X-rated to R-rated to PG-rated material (or the reverse). Today’s TV set lets you control brightness, volume, and channel. Tomorrow’s will allow you to vary sex, violence, and political leaning.
