  As described above, in the reception system 14, information is transmitted and received between the DTV receiver 21 and the wireless remote commander 22 by bidirectional wireless communication, and the DTV receiver 21 uses the wireless update commander acquired from its own update data. Since the update data of 22 is extracted and transmitted to the wireless remote commander 22, and the wireless remote commander 22 updates its own software using the update data, the software inside the wireless remote commander 22 can be more easily updated. Can be rewritten. As a result, problems with existing functions are resolved or new functions can be used.

Although the DTV receiver 21 downloads data using BS or CS digital broadcasting, it may also download data using terrestrial digital broadcasting. In this case, update data provided to a digital terrestrial broadcast station is transmitted and received by the antenna 31B.

  In addition, in the DTV receiver 21 and the wireless remote commander 22, the software of the DTV receiver 21 and the wireless remote commander 22 is updated. However, only the software of the wireless remote commander 22 is updated. May be. In that case, the DTV receiver 21 downloads only the update data for the wireless remote commander 22.

  The program executed by the computer may be a program that is processed in time series in the order described in this specification, or in parallel or at a necessary timing such as when a call is made. It may be a program for processing.

  The embodiments of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
