Functional Description

6.5.1.1ARIB Support

Please refer to the ARIB TR-B15 Operational Guidelines for Digital Satellite Broadcasting (detailed Implementation guideline for receiver) for an exhaustive coverage of this topic (http://www.arib.or.jp/english/html/overview/ov/tr_b15.html). The Intel® 82854 GMCH supports the ARIB resolutions in Figure 8 except the Motion Picture (Movie) Plane and the Movie/Still picture selection plane. This device supports the remaining planes outlined in Figure 8.
