Having worked as an Account Executive for a local cable company, these are probably local ad insertions over the national ad. It happens on DirecTV and Dish as well. Commercial time (when commercials air) for every given program is preset. The national network has ads filling all of their time slots. Local cable companies sell some of that ad time to local businesses. Depending on a number of factors, including the age of their equipment, the length of their ads, etc., there can be a momentary "blip" between the start of the national ad, and the local ad insertion.
Having said this, advertising is the bane of human existence, which is why I am no longer an Account Executive for a local cable company.
