they are also scared of losing box rental revenues. Which is why we do not see an active and wide push for something like DOCSIS for CATV. Basically so anybody could make a box and it would just get a bootfile telling it what channels it can decrypt.
I think True2Way was supposed to be this at launch but it blew up before first stage separation. -- [65 Arcanist]Filan(High Elf) Zone: Broadband Reports
Of course, just like the music industry wanted you to spend $15 for an entire CD just to get one song. That's the reason they won't cut programming retransmit deals and the reason they cap HSI (there is no bandwidth crunch, it's all bull to stop people from using the service to stream video).
Yeah Tru2Way was supposed to allow consumers to buy their own set top, and get the cable card from the cable provider. The only thing was you still have a motorola specific cable card and a cisco specific cable card. The cable card software was what restricted PPV access and such, and last time I was using it(I worked for a company developing Tru2Way set top software) the cable card software was quite buggy as well as the actual firmware on the set tops was very buggy and slow.
Since that company was dismembered and eaten by Comcast, I haven't followed Tru2Way so perhaps it's gotten better.
