A cover ( ) capable of opening/closing movement is attached to an opening of a card insertion part ( ). A detector ( ) for detecting opening/closing of cover detects whether the cover ( ) is in open position or in closed position. After detecting transition of the cover ( ) from open position to closed position, the detector ( ) for detecting opening/closing of cover outputs a reset signal ( B). After receipt of the signal ( B), a controller ( ) restarts a receiver ( ). After restarting, the controller ( ) determines whether a memory card ( ) is connected to a connector ( ) on the basis of a detection result ( ) from a card detector ( ). When it is determined that the memory card ( ) is connected to the connector ( ), the controller ( ) loads a program in the memory card ( ) into a RAM ( B). A copy of information ( ) in the memory card ( ) is made into a flash memory ( ) on the basis of the loaded program by the controller ( ). It is possible to provide an upgrading device capable of upgrading information in a memory easily without requiring deep background knowledge.

Upgrading device and method of upgrading

A format converter has a memory capable of storing a video signal of progressive or interlaced scan construction and having one of a plurality of video data sizes and one of a plurality of frame rates, a frame rate controller using the memory to control a frame rate of the video signal, and a conversion filter for converting a video data size of the video signal. With the above configuration, conversion of the signal is effected without losing or detracting the features of the source material of the video signal. The conversion of the video data size is preferably effected on the output having the frame rate adjusted. With the above configuration, the format of a video signal can be converted without degrading the quality of the input video signal, and at the same time the required memory capacity can be reduced.
