Abstract (en)
An apparatus for providing an enhanced RBDS open data application group data format such that framed data can be sent using the RBDS protocol. More specifically, bit locations within the open data application (ODA) group data signal format are defined in such a way that information concerning the start, middle and end of a frame of data, and the type of data contained in that frame, can be transmitted to a receiver unit. Data that comprises the start of a frame of data is designated as such by bit locations referred to as a frame control field. Subsequently, data within the frame is designated as comprising the middle of that frame of data. The data that comprises the middle of the frame of data can significantly extend the frame size. Subsequently, when the data that comprises the last portion of data contained in the frame is transferred, the frame control bits indicate that the frame of data had been reached. With such an arrangement, frames of data can be transmitted to a receiver unit as a stream of related data groups. <IMAGE>
