The availability of high-quality, low-latency video can significantly impact Department of Defense (DoD) and Special Operations Forces (SOF) mission success in real-time decision-making. High-Efficiency Video Coding (HEVC/H.265) is proven to maintain superior video quality for mission-critical applications while overcoming common challenges posed by constrained network bandwidth.
The DoD and SOF generally have limited bandwidth across which to transport tactical data from multiple sources such as satellites, Unmanned Aerial Vehicles (UAVs) and autonomous robotic systems.. Bandwidth constraints present a bottleneck even as actionable video data increases with the widespread deployment of surveillance cameras and the growing reliance on mobile content capture and delivery from warfighters and agents on the ground via smart phones, tablets and other IP-connected devices.
Beyond the sheer volume of video data streaming into ISR operations today, larger resolutions such as HD and Ultra HD exponentially increase the raw content to be processed and delivered to warfighters and agency officials. Full-motion video can be compromised by video files so large they cannot be properly transmitted or so poorly compressed that they lose vital image acuity.
Video compression that can supply large volumes of HD content in real time for backhaul over constricted networks and within a minimal footprint addresses this issue. HEVC is designed to provide high-quality video at substantially lower bitrates as compared to MPEG-2 and H.264. Proven, commercial, broadcast-grade HEVC solutions can support DoD and SOF applications such as Intelligence, Surveillance and Reconnaissance (ISR) and video backhaul contribution.
AWS Elemental has deep experience developing video codecs from open specifications to full implementation using general-purpose programmable architectures (GPUs and CPUs). With a flexible, software-based architecture, video processing solutions from AWS Elemental offer support for HEVC via a seamless software upgrade.
Easing the transition to HEVC within legacy MPEG-2 and H.264 infrastructures, upgradeable solutions like those from AWS Elemental can incorporate new compression approaches much more quickly than existing, fixed hardware encoding and decoding platforms. Flexible software running programmable hardware makes the AWS Elemental computing platform an ideal fit for HEVC.
AWS Elemental support for HEVC also eliminates configuration complexity, optimizes mobile video delivery and reduces total cost of ownership. Because AWS Elemental builds software designed to run on off-the-shelf CPUs and GPUs instead of fixed function processors, a mix of MPEG-2, H.264 and HEVC video content can be processed using a single platform.
AWS Elemental video processing solutions also perform real-time, full-motion video for UAV applications and DoD Information Assurance Certification and Accreditation Process (DIACAP) compliant. They are ideally suited to an array of DoD and SOF applications including internal broadcasts, remote training, location monitoring, IPTV distribution, content library conversion and global communications.
- Benefits of HEVC:
- Bitrate reductions of up to 50% for fixed video quality compared to H.264
- Higher-quality video at the same bitrate
- Maintenance of line 21 Closed Caption (CC) data
- Ability to pass through encoded KLV metadata
- A standard syntax to simplify implementation and maximize interoperability
- Network-friendly support, video wrapped in MPEG transport streams
