Abstract
A main body of a broadcast receiver can receive a large amount of input information in a short time through a keyboard. The main body can discriminate through which an input operation has been performed a remote controller and the keyboard. The main body comprises a remote-controlled operation receiving unit provided to receive a remote-controlled operation input, a universal serial bus (USB) terminal, an input identification unit for identifying between the presence of the remote-controlled operation input and the presence of an operation input through the USB terminal, and a display mode switching unit for switching display modes of a display unit in response to an identification result from the input identification unit.
Claims16
A method comprising:
- configuring the broadcast receiver to receive a first input signal supplied from a first character input device;
- configuring the broadcast receiver to receive a second input signal from a second character input device;
- and
- determining whether the broadcast receiver receives the first input signal from the first character input device or the second input signal from the second character input device;
- and
- switching a mode of a display screen on a display unit from a first mode to a second mode in response to determining that the broadcast receiver is receiving the second input signal.
A broadcast receiver, comprising:
- a display unit including a display screen;
- a remote-controlled operation receiving unit;
- an universal serial bus (USB) terminal;
- an input discrimination unit adapted to detect a presence of input signaling through the remote-controlled operation receiving unit and a presence of input signaling through the USB terminal;
- and
- a display mode switching unit in communication with the input discrimination unit, the display mode switching unit being adapted to switch a mode of an input screen displayed on the display screen based on whether input signaling is detected through the remote-controlled operation receiving unit or through the USB terminal.
A method for a broadcast receiver adapted to receive a digital broadcast signal, reproduce a program from the received digital broadcast signal, output the recovered program to digital recording equipment, and receive inputs at a remote-controlled operation receiving unit and a universal serial bus (USB) terminal, comprising:
- discriminating between character input signals received through the remote-controlled operation receiving unit and through the USB terminal;
- switching modes of a display screen of a display unit in response to whether the broadcast receiver receives a character input signal through the remote-controlled operation receiving unit or a character input signal through the USB terminal;
- and
- processing the character input signals from the remote-controlled operation receiving unit and the USB terminal.
