This paper presents the development of an ATSC terrestrial data receiver to be used in multimedia datacasting for remote and rural communities. In the context of a project put forward at the Communications Research Centre Canada to deliver interactive multimedia to remote and rural areas in Canada, a receiver capable of extracting Internet Packets (IP) as well as video and audio transport streams (TS) based on the Advanced Television Systems Committee (ATSC) terrestrial digital television system is developed. This paper describes the design, implementation, functionality, as well as several applications of this receiver which plays an important role in the interactive multimedia datacasting system. The ATSC terrestrial transmission chain from the server at the transmitter site to the receiver (client) at the end-user's premise is presented. A number of possible implementations for a return channel are proposed. Preliminary results of laboratory trials as well as plans for field trials are presented.
