    • A receiver and a method for processing data communication with a terminal in the receiver are provided to enable a user to watch the image programs of the home receiver, cable broadcasting connected to the home receiver, and the image programs of external image devices through the Internet using a portable terminal at any place. A terminal connects with the Internet server. The Internet server performs the authentication of the terminal. If the authentication succeeds, the terminal transmits a control signal generated by the control command of a user to a receiver through the Internet server. The receiver changes the operation of the receiver according to the control signal provided from the terminal or selects a desired image program source and an image program. The control unit of the receiver transmits the image program processed according to the specification of the terminal to the terminal through the Internet. The Internet server transmits a close control signal to the receiver. The control unit of the receiver closes a data communication process with the terminal.

    • PURPOSE: A television system having a recording function is provided to allow a viewer to recognize a broadcasting signal recorded by the viewer when the broadcasting signal is no signal or weak electric field signal if the broadcasting signal being recorded by the viewer is different from a broadcasting signal watched by the viewer. CONSTITUTION: A television system having a recording function includes a weak electric field detector(12) and a microcomputer(14). The weak electric field detector receives automatic gain control voltage that is varied according to electric field intensity of a broadcasting signal from a recording tuner(2) to output a low-voltage or high-voltage switching signal so as to detect if the broadcasting signal is inputted in the normal state or inputted as no signal or weal electric field signal. The microcomputer judges if the broadcasting signal is no signal for a predetermine period of time or more or the signal is inputted as a weak electric field signal through the switching signal of the weak electric field detector to output a control signal to an OSD character generator and a sound output unit, thereby displaying an alarming phrase and sounding an alarm.
