Method of disseminating broadcast information |
摘要 |
<p>Broadcast information is classified in categories to facilitate user selection and filtration of the broadcast information which is processed for presentation to the user. The broadcast information is transmitted in the form of a meta frame and one or more category frames which are repeated in a continuous cycle. Meta frames and category frames are distinguished and identified by major and minor codes following a frame starting delimiter. The meta frame contains a description of each of the available categories, together with an identification of respective category major and minor codes, the frequency on which the respective category frame is transmitted if multiple frequencies are employed, and the relative position of the respective category frame within transmission cycle.
