摘要： A TV program distribution system comprises: a TV broadcast signal distribution device for distributing a scrambled pay TV program provided by a TV program provider; an auction management device for managing selling, by auction, of the viewing right of the pay TV program; an account management device for charging winning bidders of the pay TV program determined by the auction; and a conditional access management device for managing conditional access information to make it possible for each STB of each winning bidder of the pay TV program to descramble the scrambled pay TV program.The TV program distribute system sells the pay TV program by auction, limiting the number of STBs allowed to access the pay TV program, so that the TV program distribution system makes it possible for the TV program provider to collect fees of the pay TV program according to market value of the pay TV program.

摘要： In a digital TV broadcast signal receiver connected to a multi-directional antenna called smart antenna and receivable not only digital TV broadcast signals but also analogue TV broadcast signals, an optimum signal receiving direction of an analogue TV broadcast signal of an optional channel can be decided with reducing affect of ghost due to reflection of the TV broadcast signal by such as a high-rise building, or the like. An NTSC decoder takes a still image data from an analogue TV broadcast signal in each signal receiving direction of the multi-directional antenna, and performs an A/D conversion processing and a JPEG compression processing to the image data. A controller decides a direction, in which a complexity, such as bit rate of the image data is the smallest, as an optimum signal receiving direction of the channel.

摘要： In a digital TV broadcast signal receiver connected to a multi-directional antenna called smart antenna, having a first number, for example, sixteen of signal receiving directions defined in a technical standard such as EIA-909, a simplified multi-directional antenna having a second number, for example, four or eight signal receiving directions smaller than the first number is connectable. When a multi-directional antenna is connected, an initial processing is performed for confirming a number of signal receiving directions of the multi-directional antenna. When the multi-directional antenna is simplified one, the digital TV broadcast signal receiver treats the signal receiving directions more than two showing substantially the same signal sensing conditions as the same direction. Therefore, a number of times for switching the effective signal receiving direction of the multi-directional antenna can be reduced without switching indistinctive signal receiving directions in practice.

摘要： When a multi-directional antenna is connected to a digital TV broadcast signal receiver, the digital TV broadcast signal receiver measures a term suitable for switching or changing an effective signal receiving direction of the multi-directional antenna corresponding to kind or specification of the multi-directional antenna. Control signals are outputted at an interval suitable for switching or changing the effective signal receiving direction of the multi-directional antenna corresponding to the measured term so as to switch the effective signal receiving direction of the multi-directional antenna to an optimum signal receiving direction of a channel chosen by a user. Consequently, it is possible to shorten a term necessary for switching or changing the effective signal receiving direction of the multi-directional antenna to the optimum signal receiving direction of the channel chosen by the user.

摘要： In a digital recording device, image data recorded in a recording portion has its resolution decreased to be recorded in the recording portion when it is determined that the digital recording device is not being used. In other words, when it is determined that a power switch is turned off, a system portion allows an MPEG decoder to convert a bit stream of a program data at high definition recorded in a hard disk drive to image data at low resolution and allows an MPEG encoder to convert the converted image data at low resolution to a bit stream to be stored in the hard disk drive.

摘要： A digital broadcasting receiver includes an operating section configured to select a channel, and a video/audio data obtaining section configured to obtain video/audio data on a selected channel from television broadcasting signals. The digital broadcasting receiver also includes a channel table and a designated channel table. The digital broadcasting receiver further includes a channel selecting section configured such that when the channel is selected by the operating section, the channel selecting section determines whether or not the selected channel has been replaced with an alternative channel by a broadcasting station by reference to the two tables. If it is determined that the selected channel has been replaced with the alternative channel, the channel selecting section instructs the video/audio data obtaining section to select the alternative channel instead of the selected channel.
