Rohde & Schwarz successfully installed an AI-based RF test system for digital TV compliance test in Vietnam. The combination of R&S BTC Broadcast Test Center and RFSpark RF automation unleashed the full capacity of R&S BTC, enabling test labs and TV/STB manufacturers to conduct compliance test in the most cost-effective manner. The successful deployment at the Vietnam Telecommunications Authority (VNTA) is the result of Rohde & Schwarz collaborating close with local system integrator Spark Systems.

“Since Rohde & Schwarz and VNTA set up the first digital TV receiver compliance test lab in Hanoi in 2015, we have been actively involved in the development of new test systems for QCVN.63 compliance test in Vietnam,” said Eric Li, Regional Manager for Rohde & Schwarz in Singapore. “Thanks to the recent development in Computer Vision (CV) technology and big data analysis on images processing, we are able to collaborate with Spark Systems to bring this AI-based RF test system to test labs and TV/STB manufacturers in Vietnam.”

“R&S BTC’s unique combination of outstanding technical features and modular, flexible design makes it a perfect match with RFSpark AutoTester to meet client’s strict requirement,” added Jia Xiaohui, General Manager of Spark Systems. RFSpark AutoTester picture quality engine can achieve great accuracy with less than 0.1dB deviation against human tester for most DVB-T2 test cases. In addition, the automation yields consistent result when conducting repeat test.

RF Test automation currently supports a range of regional and country test specifications, such as Nordig, D-Book, RED, China DTMB, ASEAN country level specifications, and with proof of coverage on the future development on test standards.

Comprising of R&S BTC and RFSpark AutoTester, the complete system provides two working modes: a full automation by using AI powered video engine and a semi-automation that combines the instrument auto configuration and human tester subjective decision. Under full automation, the duration for a full round testing can be reduced up to 75% when working 24/7 continuously.
