Abstract

Both a received program video and an electronic program guide can be simultaneously displayed in one screen of a monitor by a scaler/OSD circuit, and a user can change the ratio of the display areas of the program video and the electronic program guide to a desired ratio by operating a remote control transmitter. A CPU controls a tuner and a demultiplexer in synchronization with the change in the ratio of the display areas of the program video and the electronic program guide, to select a target channel of acquisition of program information for producing the electronic program guide.

Claims

1. A digital broadcasting receiver that receives a digital broadcasting wave, and acquires and processes data of various types included therein, the digital broadcasting receiver comprising:

a first controller for displaying on one screen both a program video including data broadcasting and an electronic program guide; and

a second controller for changing the ratio of the display areas of said program video and said electronic program guide depending on an operation by a user,

wherein said second controller changes the ratio of the display areas of the program video to the electronic program guide based on a display mode selected by the user,

wherein said second controller performs processing for changing the setting of at least one of hardware and software for acquiring and processing said data of various types in synchronization with the change in the ratio of the display areas of said program video and said electronic program guide,

wherein said second controller performs processing for changing a ratio of the allocation for data broadcasting of filter resources in a demultiplexer used for acquiring said data of various types by separation to the allocation thereof for program information acquisition in synchronization with the change in the ratio of the display areas of said program video and said electronic program guide as the setting of said hardware,

wherein in the display mode in which it is judged that the user desires to give priority to the continuous display of the data broadcasting, the ratio of the allocation for program information acquisition of the filter resources is decreased to increase the ratio of the allocation thereof for data broadcasting.

3. The digital broadcasting receiver according to claim 1 or 2, wherein

said second controller performs processing for selecting a target channel of acquisition of program information for producing said electronic program guide in synchronization with the change in the ratio of the display areas of said program video and said electronic program guide.

4. The digital broadcasting receiver according to claim 1 or 2, wherein when the user desires to assign priority to the acquisition of program information by choosing a display mode in which the display area of the program video is large and the display area of the electronic program guide is very small, said second controller performs processing for selecting a target channel of acquisition of program information such that the acquisition of program information in a program column displayed at the center of the electronic program guide is given priority in synchronization with the change in the ratio of the display areas of said program video and said electronic program guide.

2. A digital broadcasting receiver that receives a digital broadcasting wave, and acquires and processes data of various types included therein, the digital broadcasting receiver comprising:

a first controller for displaying on one screen both a program video including data broadcasting and an electronic program guide; and

a second controller for changing the ratio of the display areas of said program video and said electronic program guide depending on an operation by a user,

wherein said second controller changes the ratio of the display areas of the program video to the electronic program guide based on a display mode selected by the user,

wherein said second controller performs processing for changing the setting of at least one of hardware and software for acquiring and processing said data of various types in synchronization with the change in the ratio of the display areas of said program video and said electronic program guide,

wherein said second controller performs processing for changing a ratio of the allocation for data broadcasting of filter resources in a demultiplexer used for acquiring said data of various types by separation to the allocation thereof for program information acquisition in synchronization with the change in the ratio of the display areas of said program video and said electronic program guide as the setting of said hardware,

wherein in the display mode in which it is judged that the user desires to give priority to the acquisition of the program information, the ratio of the allocation for program information acquisition of the filter resources is increased to decrease the ratio of the allocation thereof for data broadcasting.
