Yes, but a factor of two or three is virtually nothing compared to the resources made available by SDV. Even if their entire 870MHz is nothing but digital QAMs, that represents only 300 or so HD channels, each and every one of which must start and stop at one fixed moment. Using SDV, the "pool" of available programs can be literally unlimited. Hypothetically it could be millions, or tens of millions. In a practical sense, it means that more than 1/3 of the 1,000,000 or so receivers in a large urban market could be watching something different than what anyone else in the market is watching at that moment. If the node size were small enough, that could be bumped up to allow each and every subscriber in the entire system to be watching something different, but analyses of the traffic patterns of subscribers show diminishing returns when the average number of receivers on a node dips below a moderate multiple of the number of available SDV streams. As long as the average sub doesn't encounter the dreaded channel unavailable banner more than once or twice a year and not for more than a few minutes, they aren't going to complain. Note again the largest utilization of bandwidth across an entire market is not any number of scheduled events, nor even of any highly specialized events, but rather interactive events which require what most often is the same content thousands of other subs may be watching stream out a few seconds or minutes earlier or later than all the other copies of the exact same program. Every time an SDV sub hits <Pause> or <Rewind> on his STB, the server has to split off that sub's stream from the rest of the system watching The Apprentice. Every time an SDV sub pulls up VOD and orders Real Time With Bill Maher at 11:07 instead of 11:00, it requires a unique data stream dedicated only to that customer. No matter how much bandwidth the provider has, in a linear broadcast model this just isn't possible. Now, it's true these two particular (very popular) features of SDV are mostly made moot by having a DVR instead of an STB, but even those subs who have a leased DVR probably don't have two or more, and yet would like those capabilities on the sets which don't have a DVR attached. Most of the myriad of other services engendered by SDV cannot be duplicated on a non SDV DVR. They also cannot be duplicated by any other non-SDV equipment, which right now includes satellite services and FIOS. It would be singularly odd for either of those industries to overlook this fact. Unless they can come up with a very inexpensive 2-way satellite alternative, the satellite companies are ultimately SOL in this respect. FIOS is another matter, however. It won't cost FIOS any more to convert to SDV than it is costing the CATV providers. I'll be totally shocked if FIOS doesn't have a significant SDV or similar offering within 2 years.
