Only Satellite could deliver it, and very costly transmission, set boxes and screens.
I'm reminded of DMAC & D2MAC (too early hybrid Digital systems, killed by cheaper 20MHz to 25MHz channel FM Video with multiple FM Audio subcarriers and compatible with PAL, NTSC and SECAM baseband, so the satellite receiver only needed an FM receiver tuned 950 to 11700, later 12600 ) and a regular VCR style TV modulator. The DMAC/D2MAC needed RGB or an encoder.
I'll resist explaining here in detail why I think ANY type of portable Digital Radio other than Internet Streaming is an ergonomic failure even if the digital technology and coverage was perfect! DAB was certainly a technical masterpiece, but some issues remain.
Digital TV, SD and HD as we have it now, is a success. It's just a pity it was not progressive only and didn't include 48, 96, 100 and 120 frame rates as options.
