摘要： A portable terminal device comprises a TV receiving unit (101) and a TV processing unit (102) for receiving a television broadcast, and a control unit (109) for detecting the start and finish of switching received channels, to inform the user of a message (d5) that the channels are being switched, for the time period from the start to finish of the switching. Moreover, the control unit (109) displays information (d7, d8) on the channels and information (d7, d8) indicating the progress of the channel switching, in a display.

摘要： An image coder (1) is equipped with a coding controller (112a) which produces a transmittance coding parameter (121) for controlling the coding processing of a transmittance signal, based on a picture element value coding parameter (104) for controlling the coding processing of a picture element value signal and coding-processes the transmittance signal (102) based on a transmittance coding parameter (121), as shown in the Figure. In such constitution of image coder (1), it becomes possible to control the quality of a picture obtained from the transmittance signal of each image, according to the quality of a picture obtained from the picture element value signal of each image in a composite image, whereby redundant information in a transmittance coded signal (106) obtained by coding that transmittance signal can be curtailed, without damaging the picture quality of individual images, consequently the image signal can be recorded and transmitted without lowering the picture quality with fewer bits.
