Abstract： |
This invention relates to a medical image transmission field of radio endoscope capsules characterizing in applying the SP+SW mixed ARQ communication method including the following steps: the radio endoscope waits for and sends images according to received orders, an external portable radio receiving device sends orders for re-transmitting error packets and transmits the numbers of the error packets to get the optimum packet length, the endoscope determines the sending of the error packets continuously or discontinuously based on the re-sending order and sends an order of feeding back error packets after finishing the sending and sends an order for collecting images for the next time, if the control order is fault, the endoscope capsule will wait for till receiving a correct transmission control order. |
