Carousel Scheduling of Advertisement Contents on Digital Multimedia Broadcasting
This paper functionally designs a broadcast scheduler for the advertisement system built on top of a digital multimedia broadcasting system for fast moving vehicles. The design goals lie in improving the advertisement efficiency by giving a higher frequency to the advertisement item more users are likely to be interested in. To overcome the lack of upstream communication paths and limited bandwidth, path prediction and past history analysis techniques are exploited in estimating the current vehicle distribution. The inference engine periodically adjusts the broadcast frequency of each item so as to meet the bandwidth constraint, taking into account the estimated vehicle distribution along with the position associated with each advertisement. According to the assigned frequency, the periodic generator fills the carousel queue, from which broadcast item is taken one by one.
