There are many ways to encode broadcast messages. Have you ever looked at how an "NTSC" color TV signal is built on the older black and white TV signal ?? Do you understand "Quadrature Amplitude Modulation" ?? Or a "superheterodyne" receiver ?? There is a lot of complex signal analysis science that I've only heard of, much less understand. Compression methods, on, and on. Video capture cards already work, so a high speed broadcast signal is already available for a computer to decypher. There are whole libraries devoted to the subject of signal encoding. Much of it was written by some very wise scientists of nearly a century ago. The band width is there, the range is there, the commercial time is there, the hardware is there. >>>>>>>>>>>>>>>>>> Original Message <<<<<<<<<<<<<<<<<< On 8/8/01, 1:01:26 AM, "Andy Zbikowski (Zibby)" <zibby+tclug at ringworld.org> wrote regarding Re: [TCLUG] Digital Broadcast revisited.sdm: > > Computer Chronicles used to do this.
