Video images are closely related to people's production and life, and are the main source of information acquisition and exchange for humans. According to statistics, over 80% of human information comes from video images. In the development of human history, visual perception has played a major role in learning, production, and the transmission of various knowledge. Video technology is also constantly developing, from 576i to 4k now and 8k in the future, the resolution has expanded dozens of times, continuously meeting people's demand for high-definition video. The application of high-definition video in various fields is becoming increasingly widespread, and 3D technology is also becoming increasingly mature. There are more and more applications that require complex processing of massive video data, which also forces the video processing chip industry to continue moving forward.

1、 Introduction to Jerry Video Chip

The system framework of Jerry Video Chip is composed of various functional modules+CPU, with video encoding and screen pushing modules as the main components.

There are currently three series of video chips in production, namely AC570N series, AC540N series, and AC521N series. The AC570N series and AC540N are H.264 encoding formats, while the AC521N series is MJPEG encoding format. AC570N can be simply understood as an enhanced version of AC540N, and under the premise of basically consistent cost system, AC570N has better performance and video effects.

AC570N Features:

a. Supports dual 1080P/30FPS or quad 720P/30FPS encoding, while also encoding H.264 (AC540N series 1080+720, not quad);

b. Support the simultaneous display of four screens, with arbitrary switching of a single screen (AC540N series displays two screens simultaneously);

c. The maximum screen resolution support is FULL HD (AC540N is HD);

d. Built in OSD menu with 24 bit color, supporting multi grayscale gradient effect;

e. Built in 3 million ISPs, supporting HDR and RGBIR sensors, 3D noise reduction, and better image effects;

f. Synchronous recording of audio and video, which can be transmitted to other devices through sub stream interfaces such as WI-FI while recording;

g. Built in dual core 260Mhz CPU (adjustable), capable of running algorithms.

AC521N Features:

a. Supports 720P/30FPS, VGA/30FPS recording, and MJPEG encoding with built-in 1 million ISP;

b. The highest screen resolution supports HD;

c. Built in OSD menu, menu color is 24 bit color, supporting multi grayscale gradient effect;

d. Synchronous recording of audio and video, which can be transmitted to other devices through sub stream interfaces such as WI-FI while recording;

e. Built in single core 260Mhz CPU (adjustable), capable of running algorithms, typical application is code scanning gun.

At present, Jerry Video chips have been shipped in areas such as tachographs, scan guns, aerial photography, doorbell locks, motion cameras, four-way surveillance cameras, pipeline endoscopes, law enforcement recorders, children's cameras, and teaching microscopes. It can be equipped with WI-FI chips, Bluetooth chips, etc. to expand its application, and connect to mobile phones using apps to connect with major internet platforms.

In recent years, the term AIoT has gradually become active in people's vision. The so-called AIoT, also known as AI+IoT, means the combination of artificial intelligence technology and the Internet of Things technology to form a new integrated discipline.

Of course, the development of technology is inseparable from market demand. With the increasing demand for intelligent applications, AIoT is facing more complex scenarios, and people need to provide more efficient computing to achieve faster responses.

In this context, AIoT chips have emerged, which have more advantages in computing power and power consumption compared to traditional general-purpose chips when facing AIoT scene tasks.

2、 Jerry AIoT chip

The system framework of the Jerry AIoT chip is: audio recognition module, video encoding module, various functional modules+CPU, model AC791N series, without strict definition of market category, and belongs to the general chip category.

Currently, there are shipments in the aerial photography, speech recognition, and storytelling markets. Expected markets include low-cost IPC, baby monitor, visual doorbell, wireless code scanning gun, light control, etc. It can be paired with AC570N series chips for low-power video applications.

AC791N Features:

a. Built in dual core 320MHz (adjustable) ultra low power CPU, with standby and active power consumption of uA level;

b. Built in mjpeg encoding module, supporting simultaneous card writing and image transmission;

c. Built in voice recognition module;

d. Built in 5.0 Bluetooth and Wi Fi.

The specific application is currently under continuous improvement.

With the development of artificial intelligence technology, traditional IoT devices will tend towards intelligence, forming the AIoT artificial intelligence IoT, and evolving from 'Internet of Things' to 'Internet of Things Intelligence'.
