A communication apparatus detects the start and end of a frame of a video, and notifies information indicating that the start of the frame of the video is detected and information indicating that the end of the frame of the video is detected to a communication unit that performs communication access control and that is included in the communication apparatus. The communication unit controls an acknowledgement in a media access control level, in transfer of the video, based on the notification.

Communication apparatus and method of transferring data

A communicating apparatus having a redial function comprises: an input unit to supply a destination and a communicating mode; a redial memory to sequentially store the destination and the communicating mode supplied by the input unit, in which a plurality of sets of destinations and communicating modes are stored into the redial memory; a communication unit to perform a communication to the destination supplied by the input unit in accordance with the supplied communicating mode; and a search key to search desired one of a plurality of sets of destinations and communicating modes which have sequentially been stored in the redial memory, wherein the communication unit executes the communication in accordance with the destination and the communicating mode according to the operation of the search key.

Communication apparatus with stored sets of destination and communication mode information that automatically selects a stored set for a second communication

A communication system for communicating a document comprising image data, character code data, and the like has: a receiver to receive the document data; a memory to store the received document data; a designating unit designate the data in the memory; an instructing unit to command the printing of the designated data; a printer to print the designated data on the basis of the instruction by the instructing unit; and a controller for allowing the received document data to be printed by the printer when a failure of the memory is detected even if printing is not commanded by the instructing unit. The failure of the memory may be a lack of memory capacity. The received document data may be output to either the memory or the printer in accordance with signals from the transmission side. This system includes another instructing unit to command the deletion of the designated document data from the memory. With this system, the document data sent from the transmission side can be certainly and promptly received by the reception side and can be printed out as necessary by command of the operator even if the auxiliary memory unit on the reception side is out of order.

Data communication system

An image information processing system has a reader for reading an original image and generating image data, a recorder for recording an image in accordance with image data; a receiving unit for receiving image data from an external apparatus, and a storage unit for storing image data. In the system, during recording of the image by the recorder based on the image data generated by the reader, the image data received by the receiving unit is transferred via a bus line to be stored in the storage unit.

Image information processing system

An image information processing system has reader for photoelectrically reading an image of an original and producing an image data. The image data produced by said reader is selectively encoded in accordance with the area designation.
