Abstract

This paper presents the results of the trial of application of 5G mobile technology for video remote production of Vietnam Television (VTV). The test model had used many cameras that transmit video via 5G network to produce the live sports programs at SEA Games 31 for Golf competition. Some test results of video quality via 5G network for remote production are presented. Results of testing a sport program with 4 cameras were connected to 5G modules for live sport production. We used 2 SIM cards per a 5G module for a video camera to capture the signals. At the receiver side (Dam Vac Golf Control Room, Vinh Phuc), a decoder was used to decode the signal from IP stream to the SDI, after that sent them to a video switcher, CG, slowdown, etc. Combined with the sound system for commentary. The synchronization signal was performed through the Decoder. Test video with H.265 codec, uplink bit rate for a video camera got 15.6 Mbps, with 700ms latency (encoder-decoder). Some initial results demonstrated the ability to use 5G for production of some live sports at VTV. In addition, the test results also help program production technicians test and evaluate video/audio setup parameters to ensure minimum quality requirements for HD program production and distribution using HEVC codec uplink over 5G networks.
