Abstract: In a multi-directional antenna that is connected to a digital TV broadcast signal receiver, an RF amplifier in which its transmission gains are controlled is installed on the front of a tuner, a BER (BIT ERROR RATE) threshold is set as a reception determination standard to assess received images, and while auto-scanning, the amplification transmission gain level of the RF amplifier is controlled while changing in a phased manner to measure the BER value, and upon obtaining a BER value that is lower than the BER threshold, remaining scan and controlling transmission gains are stopped, and the receiving direction is determined.

Abstract: In a digital TV broadcast signal receiver connected to a multi-directional antenna called smart antenna, even when a user reshuffles a channel frequently, it is aimed to shorten a time delay between channel choice by the user and switching operation of the multi-directional antenna for switching signal receiving direction. Initially, sensitivities of TV broadcast signals of all receivable channels in all signal receiving directions are measured and measurement results are memorized in a memory. A signal receiving direction, in which a number of receivable channels is the largest, is decided as an optimum signal receiving direction with respect to each receivable channel. Even when the channel is reshuffled among these receivable channels, it is no need to switch the signal receiving direction of the multi-directional antenna. Consequently, the time for switching the signal receiving direction of the multi-directional antenna can be reduced even when the channels are reshuffled frequently.

Abstract: Single processing of the first channel search using the analog broadcasting tuner enables not only analog broadcasting channel to be detected but also the existence of digital broadcasting channel to be estimated. Furthermore, the acquisition of information transmitted on a digital broadcasting channel can be made apart from the first channel search when the channel is selected (received) or when the second channel search is performed. As a result, the first channel search (overall channel search) can be efficiently completed in a short time. In the second channel search for acquiring the digital broadcasting information, the number of physical channels to be searched is decreased by limiting to the number of the estimated channels. Accordingly, overall channel search which also acquires the digital broadcasting information is efficiently completed in a short time.

Abstract: In a television signal transmission system, CS broadcasting signals received via a master antenna are converted into intermediate frequency signals in an LNB (Low Noise Block Down Converter). The CS intermediate frequency signals then undergo conversion of the modulation format, for example, from QPSK into 64-QAM, so that CS broadcasting signals from each transponder, having a bandwidth of, for example, 27 MHz, are accommodated in a narrower bandwidth, for example, 6 MHz, which is equivalent to one channel of terrestrial broadcasting services. Then, the signals accommodated in the narrower bandwidth is frequency-shifted into a vacant frequency band in the VHF band or the UHF band. Accordingly, the CS signals accommodated in the narrower band and frequency-shifted into the vacant band are multiplexed with terrestrial broadcasting signals in the VHF and UHF bands and BS intermediate frequency signals so that all these signals are delivered to each household via a single cable.

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 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 consumer electronics appliances, for example in the case of a television set, it is known for there to be a key on the remote control which allows the user to switch over to the previously selected channel. However, a disadvantage of this conventional solution is that, once the user has jumped from one channel to the next, which is called zapping, the television recognizes only the last channel in the zapping sequence as the last channel in each case. The invention is based on the object of providing an improved method for storage of a channel. The method according to the invention for storage of a channel in consumer electronics appliance which can be switched over between different channels is distinguished in that the reception duration of the current channel is determined, and in that, as soon as the reception duration exceeds a predetermined time interval ZE, the channel is stored as a channel of interest.
