受信装置および受信方法
Document Type and Number:
Japanese Patent JP4665623
Kind Code:
B2
Abstract:
In a digital broadcasting receiving apparatus, channel selection that switches a physical channel requires a longer period of time than analog. To solve the above problem, for example, there are provided two systems each including a digital tuner and a decoder, wherein channel selection and decoding are carried out by a second tuner and decoder respectively, when the user carries out the channel selection operation. During this time, the first system continues decoding. At the moment when the user carries out the channel selection operation, the luminance is decreased to some extent to allow the user to intuitively know that the channel selection operation is started, and then the luminance is further decreased gradually. When the luminance reaches zero, the decoding is started in the second system, and then the system to display is switched.
