Shanghai Media Group (SMG) marked the occasion with a broadcasting milestone: the expo’s first-ever 4K ultra-high-definition live coverage. Global audiences experienced this groundbreaking transmission through an expansive digital ecosystem spanning Dragon TV’s 4K UHD channel, Shanghai News & Integrated Channel, the Knews digital media network, ShanghaiEye international communication channels, and the Kandongfang mobile app.
This achievement didn’t emerge overnight. Building on a partnership forged at the inaugural 2018 CIIE, TVU has consistently served as SMG’s strategic technology partner, providing live broadcasting support for eight consecutive years. At this year’s expo, SMG deployed TVU’s cutting-edge One 5G live backpacks with full 4K capability for the first time, achieving ultra-high-definition real-time transmission and establishing a new benchmark for CIIE coverage. The technological leap was unmistakable.
4K Technology Elevates Expo Coverage
Dragon TV’s recent launch of its 4K UHD channel set the stage for this year’s groundbreaking expo coverage. SMG planned comprehensive 4K production to deliver an immersive “virtual tour” experience that would transport viewers directly into the exhibition halls. The venue, however, presented formidable dual challenges: 4K’s voracious bandwidth demands and the unpredictable mobile signal environment characteristic of massive indoor spaces packed with interference.
TVU One’s next-generation ISX transmission technology rose to meet these obstacles head-on. The system intelligently aggregated multiple 5G and 4G connections to forge a robust, high-bandwidth uplink channel. Combined with sophisticated video processing technologies—including HEVC (High Efficiency Video Coding) intelligent variable bitrate encoding and forward error correction—TVU One delivered what broadcasters dream of: ultra-low latency, virtually flawless 4K/50p HDR signal transmission. The result exceeded even the rigorous requirements for live coverage of major political and economic events.
Agile Mobile Reporting
Over the course of 200+ broadcast hours, SMG orchestrated a technical symphony. Three field studios from its Media Convergence Center, Radio Center, and Yicai Media Group enabled seamless integration across multiple screens and distribution channels. The scale was impressive. Reporter teams from numerous divisions, equipped with TVU One backpacks, navigated the bustling exhibition halls with remarkable agility, threading through international visitors and exhibitors to provide extensive on-the-ground coverage from the National Pavilion, Enterprise Exhibition areas, and the prestigious Hongqiao Forum.
Leveraging TVU One’s unwavering performance, reporting teams conducted countless live standups and mobile broadcasts, comprehensively showcasing the expo’s most compelling moments. Whether conducting in-depth interviews within individual pavilions or transitioning rapidly between sprawling exhibition zones, TVU One ensured consistently high-quality real-time transmission. Through synchronized broadcasting on television and mobile platforms, global audiences experienced pivotal expo moments the instant they unfolded.
The impact was tangible. This agile mobile reporting approach heightened viewer engagement dramatically while enhancing coverage timeliness. The 4K ultra-high-definition footage captured what standard definition simply cannot: intricate product details, the palpable energy of the venue atmosphere, and the genuine excitement radiating from exhibitors and attendees alike. “Virtual tours” transformed into truly immersive sensory experiences. Viewers weren’t just watching the expo—they were there.
Eight Years of Innovation Partnership
SMG’s eight-year commitment to TVU as its CIIE technology partner speaks volumes, testifying to both TVU’s technical excellence and its relentless pursuit of innovation. The journey from 2018’s HD broadcasts to today’s 4K ultra-high-definition represents far more than incremental technical evolution. It reflects a shared vision. TVU and SMG have advanced in lockstep, actively shaping rather than merely witnessing the technological transformation of expo coverage.
This year’s triumphant coverage demonstrated SMG’s formidable professional strength in broadcasting while simultaneously highlighting TVU’s performance as an indispensable strategic technology partner. As a veteran in live video production technology for media organizations worldwide, TVU remains unwaveringly committed to delivering innovative products and meticulous service that anticipate industry needs before they fully emerge.
