With the rapid development of science and technology, our lifestyle is constantly changing, and digital audio technology is becoming an indispensable part of People's Daily life. In this context, the introduction of the SASO-2938:2019 standard has brought a new quality assurance and user experience standard for digital audio broadcasting (DAB) functional products.
1. DAB technology
Digital audio broadcasting (Digital Audio Broadcasting, DAB) technology is an advanced broadcasting technology that uses digital signals to transmit audio content. Compared with traditional analog broadcasting, DAB technology has several significant advantages, such as high sound quality and clarity, expanded broadcast coverage, multiplexing capability, and interactivity and data services. The introduction and development of DAB technology has brought significant technological advances and user experience improvement to the broadcasting industry, becoming one of the main choices for modern broadcasting.
2. SASO-2938: Core points of the 2019 standard
SASO-2938:2019 is a technical specification for the Saudi Arabian Standards Organization (Saudi Standards, SAB, Metrology and Quality Organization, SASO). The standard not only covers the requirements of receiving performance, such as receiving sensitivity, signal-to-noise ratio and frequency range, but also emphasizes the requirements of the product in terms of ease of operation, security and user experience. By following the SASO-2938:2019 standards, manufacturers are able to ensure that their products are competitive and reliable in the Saudi market, providing consumers with an excellent digital audio experience.
3. Accurate performance testing
Through a strict testing process, the SASO standards ensure that the product can stably receive, decode, and play digital broadcast signals in different environments. Whether in high-rise buildings or in remote areas, users can enjoy a high-quality audio experience. The following are the test items and requirements related to the DAB:
(1) General requirements
(2) RF requirements
(3) DAB+ channel decoding requirements
(4) Audio decoding requirements
(5) Functionality and user interface
(6) Announcement signalling and switching, service labels
(7) User information
4. Rich and diverse of program content
Compared with traditional AM / FM broadcasting, DAB technology can not only provide a more clear and more stable sound quality, but also transmit multiple program streams through multiplexing technology, providing users with a richer variety of audio options. SASO standards ensure that the product can fully support multiplexing, channel switching and program navigation functions, enabling users to more easily browse and choose their favorite programs and enjoy a personalized audio experience.
With the continuous progress of technology and the continuous consumer pursuit of audio experience, DAB technology will continue to develop in the direction of intelligence, networking and multimedia integration. SASO-2938:2019 standard is not only the certification of existing technologies, but also leads the future development of DAB capabilities in emerging applications and innovation. The standard will continue to be updated and improved to promote the application of DAB technology in many areas, including car audio systems, home entertainment devices and mobile devices.
The selection of DAB function products that meet the SASO standards means the selection of excellent digital audio experience, optimized user operation, and safe and reliable guarantee. These products will not only bring you high-quality music, news and entertainment programs, but also meet the personalized auditory needs. Let us keep pace with The Times, choose the best quality DAB function, and welcome the wonderful digital audio era together!
