Nowadays, the progression of digital broadcasting has been toward establishing a user-friendly TV watching environment through personalized broadcasting services. In the consumer domain, video content filtering enables personalized broadcasting service in which a TV viewer obtains desired scenes even from live broadcasts, which cannot possess metadata. In this paper, therefore, we propose a new real-time content filtering system for live broadcasts that can be applied to TV terminals such as the set-top box and personal video recorder. Based on the proposed filtering, the TV viewer can watch not only favorite broadcasts of a main channel, but also get desired scenes from live broadcasts of other channels simultaneously. The usefulness of the proposed broadcasting content filtering is verified with sport videos on a test-bed broadcasting system.
