Embedded Video Camera and Video Communication Development Kit (TI)

Embedded Video Camera and Video Communication Development Kit (TI)

Texas Instruments (TI) launched two newest embedded video camera and video communication development kits to meet the growing demand for advanced video communication at a reasonable cost. Each kit can be used in its own unique application area. Both embedded video development kits provide interactive high-definition video communication for improved image quality and intelligent video encoding. In addition, the above-mentioned embedded development kit can also reduce the encoding bit rate by 5 times, and improve the video quality and network bandwidth through the Smart Codec Technology on TI's latest DaVinci video processor TMS320DM368.

The embedded USB camera development kit DM368EUCDK is designed to meet the needs of video camera applications that already have a video decoding host processor, such as set-top boxes, digital signage, and information stations. The kit integrates high-definition (HD) H.264 encoding at 30 frames per second at 1080p for excellent video quality.

The embedded communication development kit DM368ECDK is ideal for dual-channel video communication (encoding and decoding) that supports 30 fps 720p, including applications such as video conferencing, web cameras, video blogs, and interactive signage.

The small size of the kit enables original equipment manufacturers (OEMs) to easily embed video-capable cameras directly into terminal products, improving the interactivity and convenience of video communications. Through TI ’s fifth-generation on-chip image signal processor (DSP), various features can achieve higher image quality at extremely low bit rates, including noise filtering, video stabilization, face detection, automatic white balance, and automatic exposure And edge enhancement. The product has a high degree of integration, a small form factor, and a low price advantage, which can achieve a large number of innovations, such as allowing TV OEMs to embed these kits in terminal products to achieve high-definition video communication for consumers. In addition, intelligent codec technology can also achieve high-definition video communication for homes through standard Internet access.

Features and advantages of DM368EUCDK and DM368ECDK:

Based on the latest DM368 DaVinci video processor, it can provide H.264 encoding and dual-channel video communication for advanced image quality, up to 30 fps 1080p for advanced, main and basic types;

The software that can be implemented on the DM368 ISP provides a variety of video processing features, which can maximize the camera image quality and coding efficiency;

The intelligent codec technology on the DM368 can reduce the encoding bit rate for a given perceived quality by a factor of 5, thereby reducing the load on the network bandwidth and reducing the need for high-cost storage;

Supports UVC / UAC (USB video / audio) drivers, conforming to the USB video and audio compliance standards for data streams;

The compact form factor can meet the needs of OEM manufacturers in the embedded market, and can simplify the integration of the camera and reduce its cost;

Only the USB port can power the ultra-low power development kit;

Contains demo software and free Linux source code, enabling convenient and low-cost integration in consumer systems:

1080p30 H.264 data stream and secondary preview stream

Host application and driver (Windows / Linux)

Availability and tools

TI's embedded video camera and communications development kit is now open to accept orders and can be ordered through Leopard Imaging. The TI TMS320DM368 DaVinci video processor is now in production, and has begun to supply, can be ordered through TI and its authorized dealers.

Li-ion Battery With SMBUS refers to the battery datas can be collect through equipments based on SMBUS data communication, it usually applied to the military grade battery which need higher safety level protection .but as these battery have SMBUS inside ,it also should meet these requirements as :

1.The rated voltage is high (the operating voltage of the unit is 3.7v or 3.2v), which is about equal to the series voltage of three nickel-cadmium or nickel-hydrogen charging batteries, so as to form the battery power supply group

2.The self-discharge rate is very low, which is one of the most prominent advantages of the battery. At present, it can reach less than 1% per month, less than 1/20 of the nickel hydrogen battery.
