Receiver and method for controlling receiver

以前的电视、录像机、置顶盒等装置在观看节目以外，无法接收用于控制接收装置自身的信号和企业的宣传广告。本发明提供一种接收装置，在接收装置中设置不少于2个的接收部(101、102)，其中一个接收部的频道由视听者自由选择，另一个接收部的频道原则上视听者不能切换，而可以由节目的发送侧进行控制。另外，另一个接收部接收的数据可以自动存储，存储用于接收装置自身的各种控制的数据和企业广告等，从而可以适当地进行利用。 The receiving device is equipped with two or more receivers or tuners, and the changing of a channel for one receiving device is freely entrusted to users. At the same time, users cannot change a channel for another receiving device in principle, and a party transmitting data such as a program can control it. Additionally, the data received by another receiver can be automatically stored, and the data to control each type of the receiving device itself or advertisement for company can be stored and utilized from time to time.
