Abstract
tracks different avails including duration and bandwidth of the avail, and uses a number of schemes to determine if the ad can be placed in the avail. The advertisements may be transported over an in-band advertising channel or over an out-of-band advertisement channel. At the multiplexing end, the ads may be multiplexed in one or more program streams synchronously, plesiochronously, or asynchronously. In either case, a dynamic linking process is used to insert the selected advertisements in the program streams.
