When the main power supply is turned off, the power supply of a video display unit is turned off and the audio signal is muted. At the same time, a time counting unit counts time, and before reaching a predetermined time, a display unit is lighted to notify a quick restart period. In the case where the main power supply is turned on during the predetermined time, the power supply of the video display unit is turned on to cancel the audio mute mode. In the case where the main power is not turned on upon lapse of the predetermined time, the power supply of the receiving unit is also turned off.

According to one embodiment, a heat radiating apparatus comprises a shielding case having holding panels thereof arranged at locations substantially opposite to a circuit component to extend from a flat panel of the shielding case, which extends substantially parallel to a circuit board, towards the circuit board so as to cover the surface of the circuit board on which a circuit component is mounted. The head radiating apparatus further comprises a heat sink attached to the holding panels of the shielding case for coming into direct contact with the heat conductive sheet on the circuit component when the circuit board is covered with the shielding case.

Heat radiating apparatus in electronic device and heat radiating method

A heat sink is attached to fixing plates of a shield case. When a circuit board is covered by the shield case, the heat sink comes into contact with a circuit component mounted on the circuit board through a heat conduction sheet. Further, clearance holes, which are approximately closed by first heat dissipation plates, are formed to the shield case.

Heat dissipation device for electronic equipment

When converting an interlace video signal into a non-interlace video signal by interpolating a scanning line of the interlace video signal, black stretching is carried out with respect to the interpolated scanning line. Thereafter, black stretching is carried out with respect to a non-interpolation scanning line of the converted non-interlace video signal.
