Abstract: A receiving device used in a digital television includes an automatic storage section obtains the channel information on physical channels at which a program is broadcast, when the channel information contains any other physical channels therein, registers the physical channels thereof in a channel map, decides whether the physical channel which is switched has been registered in the channel map, and if the physical channel has been registered, not to detect whether a program is broadcast at the other physical channels. In this case, information of any other physical channel is present in a VCT, this other physical channel is registered in the channel map without detecting whether a program is broadcast at the channel. Therefore, the total number of the channels to be detected on whether a program is broadcast can be decreased, thus reducing the time for performing the automatic storage function.

Abstract: When a digital broadcast is currently extracted and a switching direction instruction is accepted, determination is made as to which of a CH number (analog number) next to a currently extracted channel in the switching direction according to the order indicated in an analog CH map and a CH number (digital number) next to the currently extracted channel in the switching direction according to the order indicated in a digital channel map is closer to the number of the currently extracted channel (extracted number). When closer to the analog number, the channel is switched to the analog number. When closer to the digital number, the channel is switched to the digital number. Thus, the channel of analog and digital broadcasts can be switched in a seamless manner.

Abstract: A digital broadcasting receiver that uses a channel map containing broadcast information such as channel numbers and virtual channel numbers is described. When a user selects a certain digital channel number, a control unit consisting of a CPU makes a search as to whether or not the number exists in the channel map. If the number does not exist, “No Signal” notice is displayed on a display and if the user selects a scan instruction then, the entire range of frequency band of the broadcasting signal is scanned. If a signal that corresponds to the digital channel number exists, its broadcast is received. Therefore, a search is possible even when the user knows only a virtual channel number and the digital channel number entered by the user is not registered in the channel map.

Abstract: In a channel selection device of the invention used in a digital/analog broadcasting receiver, in instructing changing a channel, either one of the UP/DOWN key pair or the RIGHT/LEFT key pair can be used to change a main channel while changing the other pair to change a sub-channel. Thus, by using the keys distributed between the main channel and the sub-channels, a correlation can be given between the key operations and the channels' hierarchical construction to thereby facilitate the changing and selection of the main channels and the sub-channels in the hierarchical construction in digital/analog broadcasts.

Abstract: In a broadcast receiving system for receiving the digital broadcast, when the selection of “channel selection menu” is inputted by the user, the channel information stored in a memory is read to decide whether the configuration of a sub-channel is identified during the current operation, and a descriptor “x” is assigned to the sub-channel not identified to be made displayed in the channel information list on “channel selection display,” thereby distinguishing it from other channels. This allows the channel whose sub-channel cannot be identified to be OSD displayed distinguishing it from other channels such as for analog broadcast and the like.

Abstract: In a broadcast receiving system for receiving the digital broadcasting, when the selection of “channel addition/deletion menu” is inputted by the user, received broadcasting signals are decoded to obtain collectively the channel information of the digital/analog broadcasting. This channel information is compared with channel information made stored in a memory to distinguish the channel having suspended from the channel having been resumed, and the distinguished information is made OSD displayed for each channel. The user operates an input device to select a desired channel, and inputs an instruction of the channel addition/deletion with an addition button or a deletion button to update the data stored in the memory.

Abstract: A television signal receiver comprises a tuner, a decoder, a first storage medium that stores a frame of video signals extracted by the decoder as a captured image, a second storage medium that stores sound data representing a variety of shutter sounds to be generated for informing a user that a captured image has been stored in the first storage medium, and a sound generating circuit that, when a captured image is stored in the first storage medium, selects a shutter sound among the variety of shutter sounds represented by the sound data stored in the second storage medium and generates the selected shutter sound. Since the television signal receiver is configured to generate a shutter sound when a captured image is stored in the first storage medium, it can inform a user about storage of a captured image in the first storage medium without causing video images of a television program to be partly hidden from view.

Abstract: A TV broadcast receiver measures, at least two times, a signal intensity in a maximum receiving direction and a signal intensity in the 180 degree opposite receiving direction among 16 receiving directions of a smart antenna. If the signal intensity in the maximum receiving direction is significantly different from that in the opposite receiving direction, it determines that the smart antenna is connected. If the signal intensity in the maximum receiving direction is substantially the same as that in the opposite receiving direction, it determines that the smart antenna is disconnected. It displays messages of the connection and disconnection of the smart antenna on a monitor. This makes it possible to quickly determine whether the antenna connected to the TV broadcast receiver is a smart antenna or a stationary unidirectional antenna.

Abstract: A multi-directional antenna connected with a digital television broadcast signal receiver is arranged not to move one full turn instantaneously in response to an abrupt drop down in the intensity of a received signal thus to avoid any downward overshooting of the intensity of the received signal and eliminate any useless direction searching time while remains favorably controlled to face in the direction where the intensity of the received signal is at optimum. More specifically, the maximum of the intensity of a received signal at each channel is measured and the threshold is set to a level lower than the maximum. When the intensity of a received signal has dropped down from the threshold, the antenna remains not turned within a predetermined period of marginal time. The antenna is moved one full turn only when the intensity drops down from the threshold and stays continuously over the predetermined period of marginal time.

Abstract: A TV receiver preliminarily measures and stores, in a memory, data of best receiving directions, each giving maximum signal intensity, of a multi-directional antenna for receivable channels. When the antenna rotationally shifts physically for some reason, one channel is selected and subjected to measurements by an omni-directional scanning again to determine a new best receiving direction. A receiving direction number difference between the stored best receiving direction and the new best receiving direction of the same channel is determined. Using the receiving direction number difference for the one channel, all data stored in the memory are renewed at one time, the data being the best receiving direction numbers and the signal intensities therefor for all the channels. The antenna direction can be quickly adjusted to the rotational shift by new measurements for one channel, without requiring time to make unnecessary measurements for all channels, achieving a best receiving condition steadily.
