Analog Devices\' DC-VA-H264-10B-30-1080-EVXC-SL Evaluation and Demonstration Boards and Kits are versatile and easy to deploy and operate, making them a great solution for evaluation, demonstration and usage in practical applications. This article will take a closer look at their features, benefits and the working principles behind them.

The DC-VA-H264-10B-30-1080-EVXC-SL boards and kits are designed to enable high-quality, high-performance H.264 video resolutions up to 1080P@30fps in a range of USB video capture formats. The kits are equipped with an embedded board module, which features a dual-channel H.264 snapshot capture engine, enabling the capture of both HD video streaming (1080P/720P/480P) and digital still captures. This also supports real-time video or still image output. The board module also features a range of integrated interfaces, including an RS-232 serial port, an I2C port and two USB ports.

The DC-VA-H264-10B-30-1080-EVXC-SL boards and kits continue to benefit from the development of Chips& Technologies’ highly integrated video encoder, the H.264 10bit Encoder. This enables the boards and kits to achieve a valuable real-time snapshot and video encoding, whilst significantly reducing the developer’s time to market and reducing the overall development costs. The platform also offers improved video quality, including HD video streams up to 1080P@30fps.

The DC-VA-H264-10B-30-1080-EVXC-SL board modules can be plugged into PCs, tablets, game consoles or any other compatible USB device, and can support simultaneous capture of two channels of HD video. This is thanks to the integration of a mini PCI-E to USB3.0 bridge chip and a USB 3.0 hub, which provide multiple USB 3.0 ports. This allows the board to capture 1080P video at 30fps and capture five channels of simultaneous HD video, all from a single USB 3.0 port.

The board also supports a range of USB capture formats, including USB2.0, USB3.0 and USB3.1. The module also features an embedded FPGA, allowing for the further expansion of functionality, such as data storage, transmission and even an integrated watchdog timer. The FPGA’s scalability also boosts I/O rates, offering a wide range of capture and play solutions. Additionally, the FPGA provides a buffer for the I/O operations, so can be made to capture the real-time streaming video in physical memory. This reduces latency and allows the user to capture the video without dropping frames.

The board is pre-configured with the DC-VA H.264 10bit encoder, providing high-quality encode performance. Its unique combination of features and performance benefit from the H.264 10bit encoder’s variable bitrate control technology, enabling high quality but low bit rate encoding support. The 10bit encoding support includes the use of the Advanced Prediction (AP) and Advanced Loop Filter (ALF) algorithms, which provide superior compression performance compared to other 8bit encoding solutions.

The DC-VA-H264-10B-30-1080-EVXC-SL evaluation and demonstration boards and kits offer a vast range of applications for real-time streaming of HD video, or for the creation of stunning custom video demos. With their versatility, ease of deployment and great performance, they are a great choice for a wide range of projects and applications.
