Transmission data processing method, information processing method, transmission device, and reception device

摘要

Disclosed is a technique for providing a transmission data processing method and the like capable of estimating a communicable band in a heterogeneous multi-radio network at a higher speed and minimizing the deterioration of the video quality even if an unavoidable fluctuation occurs in a band available for transmission. According to the technique, there is provided a transmission data processing method at a stage prior to data transmission by a transmission device 100 for providing the data transmission to a reception device 200 as a communication partner, including: a priority giving step of giving priority to each data of multiple pieces of data, to be transmitted to the reception device, based on a predetermined criterion; a feedback receiving step of receiving, from the reception device, feedback information on data transmitted from the transmission device to the reception device; and a distribution step of distributing, based on the priority and the feedback information received, the multiple pieces of data into a first interface and a second interface used for communication with the reception device.

主权项

1. A transmission device for providing data transmission to a reception device as a communication partner, comprising:
a radio communication unit composed of a first interface and a second interface used for communication with the reception device; a transmission unit for using the radio communication unit to transmit multiple pieces of data to the reception device; a priority giving unit for giving priority based on a predetermined criterion to each piece of the data to be transmitted to the reception device through the transmission unit; a feedback receiving unit for receiving, from the reception device, feedback information on data transmitted from the transmission device to the reception device; a distribution unit for distributing the multiple pieces of data, to be transmitted through the transmission unit, into the first interface and the second interface based on the priority and the feedback information received; and an identification unit for comparing information on routing between the transmission device and the reception device with address information on relay points between the transmission device and the reception device, where the relay points are acquired beforehand as being connectable to the first interface, to identify an address of a relay point used by the first interface, wherein the transmission unit transmits information on the identified address of the relay point to the reception device to have the reception device specify the identified address of the relay point as a via point and transmit feedback information to the transmission device through the first interface.
