Abstract: In a video encoding apparatus 1, the conversion unit 8 decomposes a coding target image by a Matching Pursuits (MP) method using a basis set based on a two-dimensional function which is made by giving parameters for curving a predetermined two-dimensional pattern to a generating function for generating such two-dimensional pattern.

As a result, a coding target image can be decomposed into a small number of atom information, and thereby it becomes possible to generate compression data with a low bit rate.

Abstract: The invention is aimed at improving the transmission efficiency of channels involved in multilink communication and reducing the load of processing. A first data transmission apparatus changes the number of transmission channels involved in multilink communication from “x” to “y”, acquires SS (sampling size) and SPF (samples per frame) associated with the number of transmission channels “y” from an SS/SPF table, generates multilink frames based on the acquired SS and SPF, and transmits them to a second data transmission apparatus. When it is detected that the number of transmission channels has been changed from “x” to “y”, the second data transmission apparatus acquires the SS and SPF associated with the number of transmission channels “y” from the SS/SPF table, generates multilink frames based on the acquired SS and SPF, and transmits them to the first data transmission apparatus.

Abstract: When an electric power is supplied to an image communication device of a user to perform telephone communication between the user and a person on the other end of the communication line, an on-off switch is automatically set to an off state on user's side under control of a video mute control unit so as to disconnect a video data coding/decoding unit from a video data receiving unit. Therefore, no video data received in the video data receiving unit is transmitted from the user to the other end of the communication line. Thereafter, when the user inputs a video mute-off instruction, an on-off switch is set to an on state under control of the video mute control unit so as to connect the video data coding/decoding unit and the video data receiving unit. Therefore, video data received in the video data receiving unit is transmitted from the user to the other end of the communication line.
