Zhongxin Chuangwei provides precise timing for Sichuan Province’s radio and television broadcasting.

Zhongxin Chuangwei provides precise timing for Sichuan Province’s radio and television broadcasting.

Recently, Sichuan Radio and Television issued a tender for time servers. Beijing Zhongxin Chuang Co., Ltd. proactively collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑7 clock server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the Sichuan Radio and Television clock synchronization project.

Sichuan People’s Broadcasting Station and Sichuan Television have been merged into a single broadcasting entity, Sichuan Radio and Television Station, while retaining the original call signs “Sichuan People’s Broadcasting Station” and “Sichuan Television.”

Sichuan Radio and Television conducted an in-depth evaluation of the DNTS‑7 clock server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and they expressed strong satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

The network time server DNTS-7, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone time server based on the NTP/SNTP protocols. DNTS-7 obtains standard clock signal information from GPS geostationary satellites and transmits this information across the network, enabling devices that require time signals—such as computers and controllers—to synchronize with the standard clock. Standard clock information is transmitted via the TCP/IP network, and DNTS-7 supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as Zhongxinchuang’s proprietary time‑broadcast packets with configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC-123 and RFC-37. Additionally, DNTS-7 supports the broadcast mode of the SNTP protocol.
