SITE DIVERSITY METHOD, METHOD FOR RECEIVING DIGITAL SATELLITE BROADCAST, AND RECEIVER FOR DIGITAL SATELLITE BROADCAST |
摘要 |
<p>A site diversity method, a digital satellite broadcast receiving method and a digital satellite broadcast receiver are provided which can make a difference of data output timing between a main station and a subsidiary station at the time of site exchange as small as possible and can perform re-synchronization as soon as possible. In the site diversity method for digital satellite broadcast, when a site exchange execution designation signal is received, the site is exchanged during a period of a TMCC information field of a predetermined specific frame of a super frame determined when the execution designation signal is received. On the receiver side, information of broadcast is continuously received by detecting a TMCC information field in a specific frame during a period of which field the site was exchanged and by establishing re-synchronization by using a super frame sync pattern W2 or W3 after the detected TMCC information field. <IMAGE></p> |
