Caller identification method for a telephone system and telephone system with a caller identifying function using the method

摘要

In a transmitting-side telephone apparatus 1 of a telephone system, a multimedia data multiplexing portion 108 multiplexes character data in a character data memory 101, image data in an image data memory 104, and music data in a music data memory 107 to produce multiplexed multimedia data to be memorized in a caller identification information holding memory 109 as caller identification information. A communication control information/caller identification information multiplexing portion 110 multiplexes communication control information from a transmission communication control portion 111 and the caller identification information from the caller identification information holding memory 109 to produce multiplexed transmission data to be transmitted through a transmitting portion 112. A receiving-side telephone apparatus of the telephone system demultiplexes the multiplexed transmission data and demultiplexes the caller identification information comprising the multiplexed multimedia data to produce unique expression based on the character data, the image data, and the music data.
