IoT MULTI-TRANSMISSION STREAMING METHOD OF IMAGES WITH META INFORMATION BASED ON REAL-TIME IoT RECORDING MEDIUM DEVICE AND SYSTEM FOR PERFORMING THE METHOD

摘要

A multi-transmission streaming method of an image comprises: encoding image data received from an image sensor; a packetizing step of generating an image data packet in one transmission unit including multiple divisions, a picture number, a packet number, and data to transmit the encoded byte stream; configuring a network module to communicate simultaneously using a wireless network including a first Wi-Fi and a second Wi-Fi having different bandwidths from LTE for multiple transmission of the image data packet; a packet scheduling step of analyzing the signal-to-noise ratio of each wireless network and adding at least one wireless network among the LTE, the first WiFi, and the second WiFi as a wireless network to a packet scheduler; determining an image data packet to be transmitted for each added wireless network when a plurality of wireless networks are added to the packet scheduler; and transmitting, by the wireless network, only video data packets, including transmitting the video data packets to a wireless network added to the packet scheduler. Accordingly, it is possible to receive a stable image from the mobile camera.
