I don’t read much in hard copy anymore, but I did leaf through the print version of PC World while on the beach last weekend. One article caught my attention as much for what it didn’t say as for what it did report. The piece, Early IPTV Uses Only a Little of Its Fat Pipe, missed a few critical points. And having made my own share of mistakes and errors of omission in the blogging business, I thought I’d make some amends by adding in information where I do have a little knowledge.
First, the IPTV story profiles AT&T and Verizon, but it does so without making the distinction that AT&T delivers all-IP TV, while Verizon uses RF with an IP return path. Essentially Verizon has chosen to use IP only for certain interactive services, and actually more closely emulates a cable network architecture than AT&T’s offering.
