On August 8th, the 31st Chengdu World University Summer Games came to a victorious close. The Chinese delegation secured the top position on the medal tally with 103 gold medals, setting a record for the highest number of gold medals won by a Chinese delegation in a single Universiade since its participation in past editions. On the evening of August 5th, the highlight of the Chengdu Universiade, the women's basketball final, captivated global attention. The Chinese women's basketball team clinched the Universiade gold medal by defeating Japan with a score of 99-91.

After receiving the crucial task of supporting 8K live broadcasting encoder products for this Chengdu Universiade, NxVi quickly assembled a team of expert technicians, aiming for flawless execution at every step, from product deployment to remote technical support. On August 5th, the women's basketball finals commenced at the Phoenix Mountain Sports Park in Chengdu. The captivating on-site visuals were real-time encoded using the NxVi Theia T1 8K encoder, transmitting 4-ch 4K multi-camera signals to the 5G+ Ultra HD offline experience center set up during the Universiade, namely the 5G studio. Another Theia T1+5G Dual 8K encoder was employed to real-time encode the 8K camera's video and transmit the signal to the broadcast truck system. These two encoders delivered an extraordinary 8K visual viewing experience to the vast audience, immersing them in a sensory feast and allowing them to share the thrilling moments of the women's basketball championship.

The NxVi Theia T1 8K encoder is the world's smallest 8K HEVC real-time encoder designed for encoding and network transmission of Ultra HD video signals (7680x4320 60p 422 10bit). The Theia T1+5G Dual 8K encoder is equipped with two 5G modules, supporting 5G Sub-6 networks, and the system can work with all three major Chinese carriers, offering an uplink speed of up to 300Mbps. It utilizes the latest efficient Ultra HD digital video compression technology, HEVC, known for its reliability, efficiency, and low latency. It encodes and processes Ultra HD video signals input via 12G-SDI or HDMI 2.1, and after compression processing through SoC, it outputs standard MPEG-TS over RTP/UDP/HLS/SRT network data streams. This product fills an industry gap and directly replaces traditional methods of video capture cards and software encoding.

Leveraging NxVi's 8K Ultra HD real-time encoding technology, the screen resolution can reach 16 times that of common 1080 60p resolution. Whether it's the Chinese sports delegation competing for gold and silver on the youthful stage or the smiles of the audience in the atmosphere of the National Games, the details are crystal clear. During the Universiade's shining moments, the 8K Ultra HD screens resonate in harmony with the passionate arenas.

Liu Xiaoming, the chief planner responsible for the live broadcast of the basketball events at the Phoenix Mountain Sports Park Basketball Complex in Chengdu, commented, 'We used multiple systems in the basketball matches of this Universiade, one of which was the 8K live broadcast system. This system employed seven sets of 8K cameras, including an 8K camcorder. The images captured by these cameras were transmitted via four 12G SDI signals to the NxVi Theia T1 8K encoder for real-time encoding and processing. The Theia T1 8K encoder has dual 5G modules built-in, enabling streaming to public network addresses via 5G networks. Subsequently, we decoded the signal using an Theia D1 8K decoder deployed on the broadcast truck, which then output four 12G SDI signals to the broadcast truck system for multi-source signal switching.

In addition to the basketball finals, the NxVi technical team, with the 8K encoder - Theia T1, also provided robust support for the VR signal transmission of the martial arts competition. Utilizing the System Monitor feature in the Theia T1 web-based system monitoring interface, the current CPU usage, temperature of each core, and network status were displayed. This allowed real-time checking of the flow data transmission status on the flow control panel and network status monitor.

Audiences can now "travel" to a virtual broadcast studio simply by wearing VR goggles, where they can "sit" in the front row of the venue to watch the games and have the freedom to choose their viewing angles. During the Universiade live broadcasts, NxVi participated in various cutting-edge technology solutions such as VR and 8K broadcasting, exploring intelligent viewing modes both inside and outside the venue, from multiple perspectives, and immersive interactive watching. This contributes to the 'Smart Universiade' experience.

NxVi has always been committed to providing top-notch products and solutions for international sporting events. From the Beijing Winter Olympics to the Chengdu Universiade and onwards to the upcoming Hangzhou Asian Games, NxVi Theia 8K encoders/decoders have been at the forefront, living up to their responsibilities and becoming an important and preferred choice for 8K live broadcasting technology at major global sporting events.
