Abstract: Prior to recording, a difference between a disc's temporal, maximum recordable length and a temporal length having been consumed by recording data is calculated. A scale is determined to allow a length of a period of a preprogrammed recording to be relatively matched on a timebase bar with the obtained difference's temporal length. Relative to the length of the period of the preprogrammed recording, an amount indicating a shortage of the difference's temporal length is calculated. An image of the timebase bar is created and the determined scale is used to create on the bar an image indicating the calculated amount of shortage, and these images are integrally displayed. Furthermore, if the current recording location and time shift reproduction location are also obtained, these locations are displayed on the same timebase bar.

The channel information storage component stores channel setting information specifying selectable channels according to the remote control identification information.

Abstract: A broadcasting receiver for receiving a digital broadcast of the invention has a sub-channel changing-dedicated operation key so that upon reception of an instruction sent from this operation key, such a sub-channel that is adjacent in a predetermined direction in the same main channel may be selected in switch-over. If the desired channel cannot be found in the predetermined direction when an upward channel-movement instruction is received, such a sub-channel is selected that has the largest or smallest channel number. Thus, it is possible to accommodate a digital broadcast that has a hierarchical construction consisting of the main channel and the sub-channels and also that has a frequently fluctuating channel configuration, thus avoiding a delay in time required for channel changing.

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: In a digital/analog broadcast receiver, when an operating unit 11 is manipulated for tuning, an MPU reads, from a received digital broadcast, a carrier frequency that corresponds to a desired virtual channel number; reads, from a ROM, a physical channel number corresponding to the carrier frequency; reads, from the ROM, a carrier frequency range corresponding to the physical channel number; and receives a digital/analog broadcast in the carrier frequency range.

Abstract: In a digital broadcast receiver, a digital broadcast receiver 10 can select an arbitrary language among plural kinds of languages and output sound by said language, and has a configuration comprising EEPROM 18 for storing the selected language, an MPU 24 for determining whether or not the selected language resides within received language data, and a sound output part 20 for outputting sound of the selected language when the selected language resides within the language data.

Abstract: A digital/analog broadcast receiving device has either in a first setting mode (proficient mode) in which whole of setting items can be changed without any limitation and a second setting mode (beginner mode) in which the setting items can be changed with some limitation. The receiving device is set in the second setting mode at the time of shipment from a factory. On the screen displaying thereon a setting menu including setting items for a various operations, such a setting item that cannot be changed is not displayed or prevented from being selected. Thus, the menu items that are desired not to be touched by a beginner user etc. can be prevented from being displayed or selected, so as to improve the operability and also protect the settings.

Abstract: In a personal video recorder (PVR) writing and recording TS data in units of blocks while moving a head over a disk recording unit of HDD, in a recording mode, a data management unit retrieves free blocks in the disk recording unit for recording the TS data formed of blocks, specifies one of the retrieved free blocks for which the degree of seek movement amount of the head becomes minimum when recording of the TS data is started from the relevant free block, and determines the relevant free block as the recording start position for the TS data. Every recording of TS data is started from the position guaranteeing the minimum degree of seek movement amount of the head, so that the seek time upon access can be reduced for each TS data.

Abstract: In a channel selection device used in a broadcasting receiver, each time a channel UP/DOWN key is pressed for changing a channel, the channel number is changed upward/downward by one immediately and, when the key is continuously held down for at least a predetermined time lapse, the first digit of the channel number is cleared to 0 and then the channel number is changed upward/downward by 10 every constant time lapse. Therefore, the channel can be changed constantly free of a fluctuation in changing speed with passing time, so that even an unskilled user can easily guess the time required to reach his desired channel to thereby get it in a short time.
