Advantech has announced a couple of PCI Express adapters that enable real-time 4K UltraHD (2160p60) HEVC encoding at up to 20x less power consumption than a software-only solution. The HVC-8700 and the HVC-8701 PCIe adapters allow broadcast video equipment makers to easily add the otherwise compute-intensive HEVC encoding task to existing or new server-based applications, stated the company


The H.265/HEVC codec is gaining momentum because it reduces bit rates by nearly 50 per cent when compared to an equivalent quality video stream encoded using H.264, enabling more channels or higher resolution video delivery over the same infrastructure. It is particularly relevant for 4K UltraHD transmission that requires a much higher stream capacity. These improvements are achieved at the penalty of much higher computation complexity, with up to 48 server-class processor cores typically required to perform a 4K 60fps software-based broadcast quality HEVC encoding in real time.

Advantech's compact plug-in encode accelerators provide OEMs with the technology to accelerate this part of the workflow without otherwise losing capacity or adding more servers, thereby helping them successfully address the challenge of UHDTV encoding in a cost-effective manner.

Both products integrate the latest MB86M31HEVC encoder SoC technology from Socionext Inc. This SoC is tailored for professional media processing and is capable of performing professional grade 4Kp60 Main10 profile HEVC encoding at less than 10W power consumption. The HVC-8700 targets file or stream-based encoding workflows in a low profile PCIe adapter format to facilitate the integration of multiple accelerators in a range of servers and appliances. The HVC-8701 adapter additionally features 4K video capture over built-in HDMI 2.0, Display Port 1.2 or 4-ch SDI-3G video inputs for acquisition-based encoding in contribution workflows. Both cards feature a simple-to-use API and example code for FFmpeg and GStreamer multimedia frameworks to streamline product development and their integration into existing applications.
