With the popularization of WiFi6 and the improvement of the coverage of communication base stations, IoT applications have ushered in vigorous development. Many chip makers have also seen new business opportunities brought by wireless communication technology and have begun to work hard to accelerate the industrial layout of IoT applications. Recently, China Mobile, together with Fu Hanwei, Credit Suisse Micro, Xingchen, Guoke Micro and other companies, released a variety of IoT main control chips in the video field.

At present, video surveillance is developing rapidly in the direction of intelligence, and is gradually integrated into the Internet of Things. It has become part of the Internet of Things. According to China Mobile's official data, relying on China Mobile's technological advantages in the field of communications, it has developed smart home-centered video services such as home Internet of Things, mobile housekeeping, and home intelligence, serving a total of 258 million users. According to the current development trend, the scale of the video IoT industry will continue to expand. At the same time, China Mobile also stated that it will strengthen cooperation with downstream terminal manufacturers to accelerate the large-scale development of the domestic Internet of Things video industry.

This time, through the cooperation between telecom operators and chip manufacturers, the collaborative work and complementary advantages of the upstream and downstream of the industry chain have been realized, which has played a positive role in improving the compatibility of software and hardware and the iterative update of products. The editor has sorted out the two chips and the following will bring you a detailed analysis of these two chips.

Fuhan Micro 5M High Performance IP Camera SoC

Fuhanwei is one of the earliest manufacturers of AD5668ARUZ-3 security chip in China. Its products are mainly front-end chips ISP and IPCSOC, which have certain first-mover advantages in digital video surveillance, video coding and image signal processing. Through complete chip categories, outstanding performance indicators, stable supply, differentiated products and artificial intelligence solution development capabilities, the company will strengthen the company's competitive advantage in this field, become a leading enterprise in the domestic video surveillance field, and successfully enter the international market. Security monitoring giant Hikvision supply chain.

Previously, Fuhan Micro and China Mobile launched a new generation of 5M high-performance network camera SoCFH8856V200, the chip adopts the main and auxiliary dual-core CPU, the main CPU operating frequency is 696MHz, the auxiliary CPU operating frequency is 696MHz, integrated high-performance ISP image processing module and The latest SmartH.265 video compression encoder.

The ISP image processing module has excellent image processing capabilities and supports line-by-line dual-frame synthesis WDR and localtoneMapping functions. This feature preserves the appearance of the captured original image through a tone-mapping algorithm, while reducing the high dynamic image (HDR) range for improved imaging. At the same time, the ISP image processing module also integrates multi-dimensional 2D.3D spatial noise reduction, which reduces image noise and enhances image effects through edge detection algorithms.

Video compression encoder supports H.264/H.265 two encoding systems, which can compress 3072* 1728 -ic/" title="1728 model">1728-ic/" title="1728 model">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title= "Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="1728 Model">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728">1728-ic/" title="Model 1728" >1728-ic/" title="1728 model">1728-ic/" title="1728 model">1728-ic/" title="1728 model">1728/2560*1440 two-frame video, reduce video Storage takes up space, which in turn increases video storage time.

In terms of audio, Fu Hanwei has added a single-channel ADC and DAC dual-mode audio signal real-time acquisition system to the chip, and the sampling rate covers 8KHz to 48KHz. At the same time, the collected sounds can also be compared to achieve the effect of echo noise reduction and improve the audio-visual quality.

In order to improve the practicability and expansion capability of the chip, the chip embeds 1GDDR3L memory, and reserves external interfaces such as I2C.SPI.USB2.0.GPIO.SADC.PWM.UART.SDIO to improve the adaptability of the chip and terminal products .

Insignia 5MAIIPCSoC

Junzheng also plays an important role on the domestic security track. It has penetrated deep into the security market over the years. Low-power design is the driving force behind the rapid development of its products. Junzheng's low-power chips are mainly positioned in the consumer market and are widely used in smart IPC cameras, electronic doorbells and other applications. However, Jun is slightly inferior to other manufacturers in terms of ISP and video encoding. In order to highlight the encirclement of the safety track, Junzheng decided to use artificial intelligence to help improve the competitive advantage of products and reduce the gap with leading companies.

To this end, Junzheng and China Mobile jointly launched the AIoTelT31ZX to help the large-scale development of the Internet of Things industry. T31ZX is an intelligent video processing chip, which is used in intelligent security, video calling, video analysis and other application equipment. The chip adopts 22nm process, which reduces the power consumption of the chip to 30%, and the CPU has strong computing power. A SIMD128AI acceleration engine is added to the chip core, with a main frequency of up to 1.5GHz. The multi-stream video encoder is integrated on the film. Starlight ISP and accelerated AI algorithm landing platform.

The video encoder supports H.264/H.265/MJPEG multi-system encoding, and the resolution can reach up to 2592 * 1920@30fps. According to the official introduction of Insignia, this chip has two video encoding capabilities compared with similar products, and its performance has been improved by two. It can also reduce the code stream by half, and support various advanced features.

Starlight-level enhanced ISP, the chip optimizes ISP performance, completely surpassing the previous generation. The noise reduction and image sharpening of 2D3D airspace have been upgraded, and dynamic range compression is also supported. The wide dynamic range compression function adaptively adjusts the light and dark effects of video imaging. The low-light video surveillance scene is especially optimized, and the RGB-Ir function is added to achieve full-color imaging at night.

By adding artificial intelligence algorithms, intelligent applications such as humanoid detection, face detection/recognition, crying detection, vehicle detection, and animal detection can be realized. When the chip is used with cellular network security equipment or customized equipment by operators, it can also be used incrementally through plug-ins to realize functions such as traffic statistics and billing.

Epilogue

After HiSilicon was sanctioned by the United States, its chip production capacity was seriously insufficient, its market share continued to decline, and market demand was rapidly released. In the post-Hisilicon era, the IoT video chip market presents a situation where princes are fighting for hegemony and hegemony. Through cooperation with the upstream and downstream of the industry chain, China Mobile has accelerated the development of the video Internet of Things industry, which has played a positive role in consolidating the position of domestic chip manufacturers in the international market.
