The national on-site conference promoting the construction of "Smart Radio and Television" recently took place in Guiyang. During the meeting, it was revealed that the Ministry of Industry and Information Technology has approved the participation of radio and television networks in 5G infrastructure development. Meanwhile, China Broadcasting Network Corporation is currently applying for mobile communication licenses and a 5G operating permit. Entering the mobile communications sector will open up entirely new avenues for business growth for the broadcasting industry. In the future, broadcasters can leverage the 5G network to build innovative content distribution platforms, enabling services such as high-definition and 4K ultra-high-definition TV live broadcasts.
If radio and television broadcasting successfully enters the mobile communications sector, the cable TV market will unlock new growth opportunities. At that time, the bottleneck hindering 4K/8K video transmission will be overcome, paving the way for ultra-high-definition video to reach its prime moment in the market. Major cable TV network operators—such as Gehua Cable, Jiangsu Cable, Hubei Radio & TV, Guangdian Network, and Guizhou Cable—are eagerly anticipating this shift, striving to seize the lead in the new era of ultra-high definition. As a pioneer of the 4K wave, Digital Technology (stock code: 300079) has already developed a comprehensive, real-scene 4K solution for ultra-high-definition content. This innovative approach breaks down barriers related to formats, protocols, and networks across all stages, ensuring both superior program quality and secure transmission—providing the technological foundation that enables radio and television broadcasters to confidently tap into the mobile communications market.
The 4K encoder from Digital Technology employs a proprietary algorithm-based color gamut mapping strategy, enabling seamless conversion between HD and 4K content while preserving the original image’s color quality—a breakthrough innovation in both video processing and color gamut transformation. To ensure consistent color hues across different formats, the encoder not only utilizes this advanced color gamut mapping technique but also dynamically adjusts saturation levels to align with various color standards. By meticulously balancing color gamut specifications with viewers’ visual experiences, Digital Technology’s 4K encoder delivers ultra-realistic imagery, allowing audiences to fully appreciate every intricate detail on screen.
At the same time, in addressing the issue of video latency, Digital Technology's 4K encoder leverages a dedicated hardware chip for computation, significantly reducing encoding delay and thereby resolving the synchronization problem between the live feed at the front end and the real-time output at the backend. The encoder features a specially designed circuit that seamlessly connects the input and output interfaces, enabling it to achieve an ultra-low latency as low as 200 milliseconds—just 1/5 of the industry average.

The era of ultra-high definition is fully upon us. Compared to 1080P video, ultra-HD videos deliver superior contrast, resolution, frame rates, and color saturation—enhancing viewers' audiovisual experience across the board. Known in the industry for its mature and reliable video technology, Digital Technology has not only successfully deployed CCTV’s 4K channel in Beijing but has also supported the launch of 4K channels in 13 provinces, firmly establishing itself as the market leader in China’s ultra-HD sector. Partners of Digital Technology include major cable TV networks such as China Media Group, Beijing Gehua Cable, Guangdong Cable, Shanghai Oriental Cable, Zhejiang Cable, Sichuan Cable, Guizhou Cable, Chongqing Cable, Jiangxi Cable, Anhui Cable, Shaanxi Cable, Jiangsu Cable, Inner Mongolia Cable, and Shenzhen Tianwei Cable.
Currently, Digital Technology has successfully implemented numerous 4K projects, establishing itself as a leading 4K video service provider in China. Moving forward, Digital Technology will continue to actively collaborate with industry partners, working together to drive the growth of the ultra-high-definition industry and contributing to the comprehensive transformation and upgrading of the broadcasting and television network ecosystem.
