The integration of audio and video SoC and AI technology brings smarter audio and video processing solutions

Audio and video SoC, or audio and video system-on-chip or system on chip, is a highly integrated chip that integrates multiple chips on a circuit board and embedded software into one chip. Audio and video SoC chips are widely used in various embedded systems, such as WiFi routers and IoT devices. In the fields of security, smart audio, etc., the computing power requirements for SoC chips are slightly lower than those of smartphones, servers, etc.

Integration of artificial intelligence technology and audio and video SoC

With the rapid development of artificial intelligence technology, audio and video SoC is constantly exploring the integration and application of AI. For example, some companies have begun to study the application of AI algorithms in noise reduction and echo cancellation to further improve audio quality, achieve better sound quality performance and a smarter and more personalized audio experience.

In the field of audio and video, artificial intelligence technology is mainly reflected in many aspects. First of all, speech recognition technology is one of the important applications of artificial intelligence in audio and video SoC. By converting human speech into text, this technology enables devices to perform various operations through voice commands, thereby providing users with a more convenient and intelligent way of interaction. Whether it is controlling lights, air conditioners and other devices in smart homes, or searching, navigating and other operations through voice on mobile devices, speech recognition technology plays a key role.

Secondly, smart audio and video SoCs also integrate advanced image recognition and processing technologies. For example, face recognition technology is widely used in smart security, mobile payment and other fields. By identifying and analyzing facial features in video streams, smart audio and video SoCs can quickly identify and track target persons, thereby improving security and monitoring efficiency. In addition, image recognition technology is also used in smart wearable devices to achieve more accurate health management and motion analysis by identifying user movements and postures. In addition

, smart audio and video SoCs also achieve intelligent analysis and processing of audio and video data by integrating deep learning algorithms. Deep learning algorithms can automatically learn and extract features from audio and video data, thereby achieving accurate classification and recognition of content. This has broad application prospects in audio and video content recommendation, precise advertising delivery and other aspects.

Smart audio and video SoCs have a wide range of application scenarios. For example, smart audio and video SoCs play a core role in mobile devices such as smartphones and tablets. It integrates processors, memory, graphics processors, and wireless communication modules, providing users with a smooth high-definition audio and video experience, while supporting intelligent functions such as voice commands and face recognition.

Home appliances such as smart speakers, smart TVs, and smart lighting are also important application areas for smart audio and video SoCs. Through integrated processors and communication modules, these devices can achieve interconnection and intelligent control between devices, providing convenient home management and entertainment experience.

The application of smart audio and video SoC in the field of Internet of Things is also becoming more and more extensive. In addition, network devices such as routers and switches also widely use smart audio and video SoC. In addition, smart audio and video SoC is also widely used in security monitoring, smart audio devices (such as TWS headphones), video conferencing systems and other fields.
