摘要： It is disclosed a transmission apparatus for a fixed length cell handling image communication method wherein moving picture data are compressed to data having a fixed transmission rate using a compression method for still pictures and then converted into fixed length cells so that image processing such as compression/decompression of the moving picture data can be performed at a high rate while keeping a high compression ratio and a high picture quality. Said apparatus includes an image data compression section (3) for performing still picture compression processing for moving picture data, which define information of a plurality of screens individually divided into a plurality of fields to be successively transmitted per unit time, in response to field timing information representative of a compression timing of each field to convert the moving picture data into variable length data which are independent of each other, a transmission buffer section (4) for converting the variable length data into fixed length data having a fixed transmission rate, and a fixed length cell transmission section (5) for placing the fixed length data and the field timing information into data parts of fixed length cells and transmitting the fixed length cells.

摘要： The present invention is intended to prevent from billing an unnecessary charge to an user by omitting AIS signals transmitted/received between a transmission side ATM unit (3) and a receiving side ATM unit (5) when a loss of service occurs in a communication network in which existing communication lines are connected by an ATM communication unit. In order to achieve the aforementioned goal, the transmission side ATM unit (3) is adapted to monitor a signal received from a communication line (1) on the transmission side and to stop the transmission of ATM cells to the receiving side ATM unit for a certain period of time when it detects an AIS signal indicating a loss of service on the transmission side and the receiving side ATM unit (5) is adapted to monitor a state for receiving the ATM cells transmitted from the transmission side ATM unit and when it recognizes that the receiving of the ATM cells is stopped for a certain period of time, to generate an AIS signal indicating the loss of service on the transmission side and to send it on the communication line (2) on the receiving side.
