Abstract
An input switch key in a remote controller is a single key for switching video input, and can be selectively operated between + side and − side. When the input switch key is operated to the + side, it can cyclically select broadcast→video 1→video 2→video 3→video 4 in the forward direction, and when the input switch key is operated to the − side, it can cyclically switch video 4→video 3→video 2→video 1→broadcast in the reverse direction, thereby improving operability.
Claims8
A remote control apparatus for operating a TV broadcast receiving apparatus into which signals from a plurality of external devices are input, comprising:
- a single input switch key configured to select any one of a plurality of signals including the signals from the external devices,
- wherein the input switch key is configured to have a first operating unit to sequentially select any one of said plurality of signals in a first direction and a second operating unit to sequentially select any one of said plurality of signals in a reverse direction from the first direction.
A TV broadcast receiving apparatus into which signals from a plurality of external devices are selectively input, comprising:
- a signal selecting circuit configured to select and output any one signal from among a plurality of input signals including first video and audio signals based on a received broadcast signal and video and audio signals from said plurality of external devices;
- a remote controller comprising a single input switch key to select any one of said plurality of input signals, the input switch key being configured to have a first operating unit to sequentially select said plurality of input signals in a first direction and a second operating unit to sequentially select the same in a reverse direction from the first direction;
- a controller configured to control the signal selecting circuit in response to an operation of the first or second operating unit in the input switch key, to cyclically select said plurality of input signals in the first or second direction, and to, when an operation has not been performed for a predetermined time after the operation of the first or second operating unit, output a signal selected immediately before the operation stop from the signal selecting circuit;
- and
- reproducing units configured to reproduce video and audio signals selected and output from the signal selecting circuit.
A remote control apparatus for controlling a display configured to display a navigation menu which displays a plurality of function items in a list every predetermined unit, comprising:
- a decision key;
- a cursor key configured so that a plurality of selection operating units are arranged at regular interval around the decision key;
- and
- page switch keys configured to be arranged in correspondence to the positions of the respective operating units of the cursor key around the same, wherein
- any one item from items displayed in a list is sequentially selected through an operation of the cursor key and an item in another unit is skip-selected by the page switch key.
