HEVC Wi-Fi LTE/5G Wireless converting system for Wi-Fi video transmitter and LTE/5G public transmitter utilizing an H.264 to an HEVC/H.265 transcoder technology

摘要

A conversion system that can be simultaneously applied to a Wi-Fi wireless network and an LTE/5G public wireless network according to the present invention includes an audio encoder 111 and an H.264 video encoder (which encode video and audio signals input from a camera for broadcasting) 112) the encoder 120 for real-time compression of the video signal with low latency; A Wi-Fi transmitter 113 that packetizes and transmits network abstraction layer (NAL) data and audio data of a compressed image in real-time transport protocol (RTP) for Wi-Fi wireless transmission; A Wi-Fi receiver 161 for receiving the transmitted Wi-Fi signal and transmitting audio data and video data to the audio decoder 162 and the video decoder 163, respectively; A decoder 160 for decoding the received audio and video data and restoring the audio and video signals; It characterized in that it comprises a transcoder of a smartphone that receives H.264 compressed video data from a Wi-Fi transmitter, decodes it into an H.265 transcoder, and re-encodes it.
