PROBLEM TO BE SOLVED: To provide a data broadcasting equipment that can automatically select and display information limited to an area around a setting position from information of data broadcasting broadcast over a wide range. SOLUTION: An area information addition device 18 adds area information data 17 to contents data 4 to obtain area information added contents 19 and a data transmitter 5 converts the contents 19 into a data broadcast signal 6. A data multiplexer carrying device 7 multiplexes the data broadcast signal 6 onto a video broadcast signal 2 and the result is transmitted as a television broadcast radio wave 8. A data broadcast demultiplexer circuit 9 receiving the radio wave 8 demultiplexes it into a video reception signal 10 and a data reception signal 12, the video reception signal 10 is displayed on a video display circuit 11 and the data reception signal 12 is fed to a reception data selection circuit 20, which gives a data broadcast signal 22 to a data broadcast display conversion circuit 13, which converts the signal 22 into data broadcast display data 14 when position information 22 denotes a receptible area and a data broadcast display circuit 5 displays the data broadcast reception data 14.
