Title: Media data transmission method, communication terminal and multi-point communication service unit
Inventor: MURAYAMA OSAMU
IPC: H04N19/115
Filed: 2001-01-25
Abstract: PROBLEM TO BE SOLVED: To transmit arbitrary data while continuing communication of media information such as a picture or voice by securing a band for the arbitrary data transmission with the insufficient idle capacity on a line. SOLUTION: In a step 10a, an arbitrary data output start instruction is waited. Upon receiving the instruction, in a step 10b, it is checked whether or not a band required for the transmission of the arbitrary data can be obtained. When it is judged that the band for the arbitrary data can be obtained, the transmission of the arbitrary data starts by a processing in a step 10d. On the other hand, when it is determined that the band is insufficient for the transmission of the arbitrary data, the band reduction processing of a logical channel for an image is executed. To suppress the amount of the image coding data in the case of image coding, there are ways such as a change in coded parameter, a change in frame rate, a change in the number of quantized bits or a change in screen size or the like.
