Portable terminal apparatus for multimedia communication
First Claim
1. In a communication terminal apparatus in which inputted video or audio information is encoded and outputted to a channel and video or audio information obtained from said channel is decoded, said communication terminal apparatus characterized by input means for inputting video or audio information, channel control sections for outputting said inputted information and receiving information from said channel, output means for outputting information obtained from said channel in the form of image or sounds, a codec means disposed among said input means, said output means and said channel control sections for encoding said inputted information and decoding information inputted from said channel in accordance with any encoding mode of a plurality of encoding modes with different power consumption upon execution and a control section for controlling the selection of said encoding mode.

Abstract
The electric power consumption by a terminal used for communication of multimedia information is controlled by changing the quality of transmitted information. The terminal is provided with input (101, 102, 106 and 107) through which such information as images and sounds is inputted, channel control sections (123 and 124) which output the input information to channels and receive information from the channels, output (103, 104, 108, 109 and 105) which output the information received from the channels in the form of images, sounds, etc., a codec (110) which is provided between the input and output and the control sections, encodes the input information in one of multiple encoding modes in which electric power is differently consumed, and decodes the information inputted from the channels, and a control section (133) which controls the selection of the encoding mode. This terminal can continue information communication for a required period of time at minimum power consumption at the sacrifice of the quality of transmitted information. Therefore, either the power consumption or quality of information can be adequately selected according to the transmission.
