Abstract: A display control apparatus includes a position acquiring unit that acquires position information concerning a current position of a mobile object; an extracting unit that extracts position information related to regions included on a road information sign; a calculating unit that, based on the position information concerning the current position of the mobile object and the position information related to the regions included on the road information sign, calculates distances to each of the regions from the current position of the mobile object; and a display control unit that sets, based on the distances calculated by the calculating unit, a display state for text indicating the regions included on the road information sign and displays, in the display state set and on a display screen, the road information sign having the text.

Abstract: A portable audio player (100) includes a decoder (14) and other devices for reproducing audio data, a microcomputer (16) for controlling starting and stopping the reproduction, and a radio communication device (24). An on-vehicle audio player (200) includes a radio communication device (64) for a bidirectional radio communication with the radio communication device in the portable audio player, a decoder (54) and other devices for reproducing audio data, and a microcomputer (56) for controlling starting and stopping the reproduction. In case that the portable audio player stops reproducing the audio data, the on-vehicle audio player starts reproducing the audio data.

Abstract: A subcode graphics reproduction control apparatus which can automatically execute fade operations between ordinary video images and graphics images. A memory for storing graphics data presenting particular images and transparency data defining transparency of the particular images is provided, the graphics data is read out in a subcode signal format from the memory according to a fade command and sent to a decoder, and with this operation a graphics video signal is generated. Also, the transparency data is read out from the memory according to a fade command, the transparency data value is gradually changed from a specified value in one direction, and a video signal input from outside and the graphics video signal output from the decoder are mixed at a mixing ratio corresponding to the transparency data.
