Product catalog summary
Product Overview: The LLC-4000 is an ultra-low latency codec designed for 4K video encoding and decoding with a focus on low latency and narrowband video transmission. It supports video encoding below 100kbps with a codec latency of 50ms or less, making it suitable for tactical edge applications.
Specifications: The LLC-4000 supports resolutions up to 2160P (3840x2160) at various frame rates (25Hz, 30Hz, 50Hz, 60Hz) and can handle video bitrates from 20kbps to 25Mbps. It uses HEVC/AVC codecs for video and AAC-LC/Opus for audio, with audio sampling at 48KHz. The device is equipped with multiple input/output options including HDMI, USB, and network interfaces.
Network and Protocols: The codec supports TCP/IP, UDP/IP, Multicast, SRT, and RTSP protocols. It includes features for error correction (FEC) and retransmission (ARQ/SRT) to ensure high-quality video transmission even in unstable network conditions.
Environmental and Power Specifications: The LLC-4000 operates within a temperature range of -10 to +50°C and humidity levels of 10% to 80% (non-condensing). It is powered by DC +12V with a power consumption of less than 20W.
Advanced Features: The codec includes adaptive rate control and peak rate control functions to optimize video transmission over narrowband networks. It can automatically adjust transmission settings based on network conditions, measuring packet jitter, packet loss, and round-trip time to maintain optimal encoding rates.
Applications: The LLC-4000 is designed for use in military and tactical environments, supporting video transmission from head-mount cameras and other devices. It enables multi-stream decoding and quad screen display, allowing up to four video streams to be displayed simultaneously.
