发明名称 Digital television broadcast signal receiver
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.
