Social media-based three-screen TV service

This paper presents a practical application of interactive TV in baseball watching. It has two features. First of all, it employs social media to generate semantic metadata of the media stream that reflect the interest of the public. The metadata are extracted by our proposed bursty feature extraction algorithm, and it provides immediate but rich summaries of live TV contents. Second, utilizing them, three-screen TV service was proposed to provide a new interactive TV watching environment. In the environment, metadata make the system available on interest-based information providing and suitable intelligent interface. We implemented a prototype system in a baseball watching environment at home or public viewing zone.
