Introduction to Grain Media GM8139/GM8138/GM8138S IP camera SoC

Headquartered in Hsinchu City, Taiwan, Grain Media is a leading provider of low-power, high definition IP camera, NVR/DVR SoC solution. Unifore newly launched home IP cameras leverage Grain Media SoCs including GM8135S and GM8136S.

In this article, we intend to introduce you the next-generation 4Kx2K IP camera SoC series processors including GM8139/GM8138/GM8138S, this series System-on-chip (SoC) adopt 40nano low-power TSMC 40nm process. Integrating Grain Media’s third generation TrueColor image processing and high performance serial interface (MIPI/Sub-LVDS/HiSPi) technology, can provide 4Kx2K/5-Megapixel/2-Megapixel/1080P high definition IP camera solution, to meet the ultra high definition demand in video surveillance market.

GM8139/GM8138/GM8138S series processors comes with complete new TrueColor image processor, high efficient H.264 HP/MP encoding engine, and 3D noise reduction technology. Under reflecting light and other high contrast lighting environment, the camera still can capture high quality image by using its WDR 3A functionality, also can greatly lower the video stream bitrate. Smart-IVS engine + High efficient ARM CPU (max. 800MHz) built-in, offering improved smart video analysis capability. This series processors integrate Faraday Technology combusive interface (MIPI/Sub-LVDS/HiSPi) technology, support working with CMOS image sensors from Omnivision, Sony, SOI, SmartSens, ON Semiconductor, Panasonic etc.

Grain Media SoCs are exclusively designed for IP cameras, creating value for customers, fit market applications, cost-effective, Grain Media solution main advantages including:

Enhanced DV level image quality

Grain Media had done a great improvement on image processing, no matter incoporating Sony, OmniVision, SmartSens CMOS image sensor, the image processor can capture true color reproduction and vivid color image. It can deliver the same image processing performance with Ambarella.

Improved video encoding

The previous Grain Media SoCs only support Baseline Profile H.264 video compression, the new generation GM8138/39 series have added Main Profile and High Profile support, video encoding efficiency and anti-motion blur effect are greatly improved.

Diversify Sensor Interface

The new generation SoC now supports 4-Lane MIPI/LVDS/HiSPi/Parallel interface, meet the needs of almost all image sensor interfaces.

Resolution support up to 8-Megapixel

As the new generation IP camera solution, offering 720p to 8-megapixel @ 15fps video resolution. Covering the needs from low definition to ultra high definition.

Built-in intelligent video engine (IVS)

The top-notch GM8139 includes such as convolution, statistical histogram, butterfly algorithm, recursive algorithm as an intelligent analysis module to achieve multiple intelligent video analysis.

High performance

This series of IP camera SoC supports speed up to 1GHz, memory support 32Bit. To meet the high CPU load video application.

Rich peripheral interfaces

Grain Media knows the market well, so the new IPC SoC come with rich peripheral interfaces. For example, supporting USB 2.0 OTG, SDC3.0, also in order to extend the applications, these SoCs can directly support 3G/4G cellular modem, WiFi module.

Low cost, Low power consumption

GM8138S has integrated 1Gbit DDR3, not only making single-chip solution easier., but also lower the total power consumption. This processor can offer 2-megapixel @ 45 fps video encoding capability.
