Abstract: In a terrestrial digital TV broadcast signal receiver capable of EPG (Electric Program Guide) display, EPG data are updated in a time as smaller as possible while a use does not watch any TV program, so that the EPG can be displayed in real time just after switching on of an electric power of the terrestrial digital TV broadcast signal receiver. When the electric power is switched off, an EPG data of a channel which will be lost the earliest is searched among the EPG data stored in the memory, and a time of day when the EPG data of the searched channel is lost is calculated. When a time for taking new EPG data reaches, the tuner is tuned to the channel, and a TV broadcast signal is received and a new EPG data is extracted from the received TV broadcast signal and stored in the memory.

Abstract: A broadcast receiving device includes a card slot, a fan, a temperature sensor, a memory component and a control unit. The card slot accepts an IC card. The fan rotates to cool the IC card. The temperature sensor measures a first temperature. The memory component stores correlation information indicating a correlation between the first temperature and a second temperature of the IC card. The control unit acquires the second temperature based on the first temperature and the correlation information. The control unit determines if the second temperature exceeds a predetermined temperature. The control unit switches from a first output mode, in which an audio-video signal is outputted via the IC card, to a second output mode, in which the audio-video signal is outputted by bypassing the IC card, when the control unit determines that the second temperature exceeds the predetermined temperature.

Abstract: A push-pull inverter allows a power supply unit to supply an input voltage to two primary windings of a transformer, and allows MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) to drive the transformer in push-pull mode so as to increase the input voltage supplied from the power supply unit and to output the increased voltage as an output voltage from a secondary winding of the transformer. The two primary windings of the transformer are mixedly wound on a same bobbin without being separated, so that when the transformer is driven, the two primary windings of the transformer are prevented from resonating with each other. This makes it possible to prevent turbulence in the input current, thereby reducing loss (power loss) of the MOSFETs, allowing the transformer to have a high efficiency.

Abstract: An optical disc apparatus comprises, an optical pickup, a signal extracting unit for reading address information and an RF signal from an optical disc based on signal read by the optical pickup, and a main controller for performing jitter control and focus control. At an initial reading of the optical disc, the main controller determines whether an address information detector succeeds in reading the address information. If not successful (NO in S3), the main controller offsets a defocus position to two points in plus and minus directions from a defocus position giving best jitter (S7), calculates an approximate curve of signal level characteristics with a peak value (S8), and adjusts and allows the defocus value to correspond to this peak value (S9). If the optical disc apparatus cannot read address information, depending on the defocus value, it increases the signal level of the address information by the defocus position adjustment.

Otherwise, if it is determined that the light beam is properly focused on the data recording layer, the controller causes the tracking operation to be performed and then starts the read operation.
