RADIO PICTURE TRANSMISSION TERMINAL DEVICE AND RADIO PICTURE TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress the increase of cumulative picture transmission delay against throughput fluctuation and the interruption of communication. SOLUTION: The device encodes a picture and transmits it as a radio signal through a communication interface. An encoding module 620 dividing one frame of the picture into a plurality of areas, sequentially encoding the picture for the respective divided areas and writing them into the communication interface, a transmission means 130 which directly transmits data written into the communication interface by using a retransmission control procedure and a picture transmission control module 630 starting the encoding and the transmission of the latest picture stored in a buffer at the timing with a reception completion notice 750 on data of the N-th picture area from the reception side of the picture as an opportunity are installed.
