METHOD AND DEVICE FOR TRANSMITTING MULTIPLE VIDEO STREAMS

Document Type and Number:

WIPO Patent Application WO/2016/082220

Kind Code:

A1

Abstract:

A method and device for transmitting multiple video streams are provided by the embodiments of the present invention. An AP sets initial transmission time and a transmission period of an I frame for each related STA, so that the interval of initial transmission time of I frames of any two STAs having adjacent transmission time of I frames is not equal to the difference between transmission periods of I frames of the adjacent any two STAs. The AP distributes a service period of the I frame and a service period of a P frame for each STA according to the initial transmission time and transmission period of the I frame of each STA. Each STA uses an exclusive channel during the service period of the I frame and the service period of the P frame, thus the transmission time of the I frame of each STA is staggered, thereby balancing the network load, and ensuring that the delay QoS of each STA satisfies requirements.
