Thanks for the math correction. Edited my post to reflect the right numbers for future reference.
said by Greg2600:Because there are 6 series STBs out there that can't run MPEG4. So, like I said, the strategy appears to be to offer new channels in MPEG4 in the short term so the transition can occur without a massive reclamation effort or a service interruption.
And then we're back to square one, which is why aren't they moving MPEG2 to 4????
As others have noted, future STB technology will allow Verizon to significantly reduce the burden of multiple STBs per home, so I doubt they are planning to make a big push for MPEG4 until more palatable options are on the table.
If anything, I could see them moving the premiums to MPEG4, since the reclamation effort required would be limited.
