    • A cable system receives a single copy of a video program, a plurality of ads, and meta-data associated with the ads at a receiver. The program is to be broadcasted on the cable system more than once, with different ads associated with each broadcast, which are typically inserted at the beginning, middle, and end of the program. The video program, ads, and meta-data are stored in a database, which are typically retrieved when the first broadcast occurs. At a first broadcast of the video program, an ad-selector processor retrieves the program and selects the ads using the meta-data, which includes ad-specific meta-data associated with each respective ad. Flexibility is afforded in ad selection for the various broadcasts of the program. The selection can be fixed by the program originator, or flexibility can be accommodated allowing the cable service provider in selecting ads for a broadcast.
