摘要： Ordinary data groups and index information indicating data names and memory locations of broadcasted data are transmitted in multiplex mode from the data broadcasting station 101, and received by the onboard terminal 103 and/or the information service station 104 through the data distribution part 102. The onboard terminal 103 detects the information which it does not hold by referring to the index information, and presents a list of data names at the onboard display part 133. The service station 104 stores separately the data groups and the index information provided from the broadcasting station 104, and in response to the download request from the onboard terminal 103, it examines whether the required data is located in SS memory part 147 by referring to the index data, and captures the required data from external memory locations defined in the index information if the required data is not stored. The download data is encrypted with the cipher key provided by the requester and transmitted through a radio wave.

摘要： A digital broadcast receiving apparatus receives a digital broadcast signal, which consists of layers each obtained by dividing a transmission bandwidth into a plurality of segments and combining some of the segments, and outputs images and/or sound from one of the layers constituting the received digital signal. This apparatus is characterized by comprising broadcasting format retention means (channel to broadcasting format correspondence table database) for retaining the broadcasting format, for each layer, of each broadcast station and switching means (layer switching means) (18) for switching the output layer based on the broadcasting format, for each layer, of each broadcast station retained in the broadcasting retention means. Thus, this apparatus can output images and sound without interruption.

摘要： A graphic processing device is composed of a main storage device (102), a drawing control device (105) and a drawing device (110). The main storage device (102) stores data relative to the coordinates of plural graphics (103, 104). The drawing control device (105) reads out the data relative to the coordinates of the plural graphics stored in the main storage device, scans the coordinate data to calculate the coordinates of intersecting points of a scanning line and the plural graphics for each position of the scanning line. The drawing control device also decides an overlapping area (AND area) or a common area (OR area) of the plural graphics on the basis of the coordinates of the intersecting points of the plural graphics and the scanning line. The drawing device draws the overlapping area (AND area) and the common area (OR area) of the plural graphics as a graphic.
