| For the triple HD's, a master site in Colorado takes the 3, processes them heavily to cram them together, then sends them back up to a satellite. Local headends downloads the feed, modulates it to a local frequency for distribution, and assigns channel numbers to each subchannel.
As far as I know, since they just pass on the feed, they can't break into an individual channel to put in local ads. For most regular channels, each is received individually and put together locally, so they can override as needed.
You can double-check by comparing the HD and SD feeds. On SciFi, it seems as if it's often a Progressive or some other insurance ad that's often overriden. Here in Chicago, they are typically ads for Luna Carpets, or Comcast ads with the Slowsky's. |
