SSIS-324 4K — Overview and Write-up

4K UHD support: Up to 3840×2160, commonly at 30/60 fps depending on input and mode.
Multi-input compatibility: HDMI and SDI inputs (typically 1–2 HDMI and 1 SDI) with automatic format detection and cross-conversion.
Multi-output options: HDMI loop-through for monitoring, SDI outputs for broadcast chains, and USB-C/USB3 capture for PC streaming.
Hardware scaling and downconversion: Real-time downscale to 1080p for legacy devices and simultaneous multi-resolution outputs.
Low-latency processing: Designed for live environments with minimal frame delay.
Audio embedding and de-embedding: Supports embedded HDMI/SDI audio and analog or AES audio I/O on some models.
Compact, rack- or desktop-friendly chassis: Often bus-powered via USB-C or small external PSU.
Control interfaces: On-device buttons, front-panel LCD/LED indicators, and remote control via Ethernet or USB software.
Recording and streaming: Internal H.264/H.265 encoding (on some variants) or raw/uncompressed capture to host via USB3.
Firmware upgradable: Field updates add new codecs, formats, and bug fixes.

Purpose: Real-time 4K video ingest, processing, storage, and delivery for broadcast, live events, and post-production.
Core components: Multi-channel 4K capture, GPU-accelerated transcoding, NVMe storage array, redundant network fabric (40/100 GbE), orchestration layer, monitoring/analytics.
Throughput target: Support 8–16 simultaneous 4Kp60 streams (10–20 Gbps aggregate video payload) with low-latency processing (<150 ms).

Verify supported frame rates at 4K — many devices limit 4K to 30 fps for full color depth, or 60 fps with chroma subsampling (4:2:0) or reduced color depth.
Check HDCP handling — some capture devices refuse to capture HDCP-protected content.
Ensure USB host bandwidth (USB3 Gen1/Gen2) and PC CPU/GPU can handle 4K capture or encoding.
Confirm supported codecs and file containers for recording (MP4, MOV, ProRes, etc.).
Confirm audio I/O formats and sample rates (48 kHz typical).
Evaluate heat dissipation and continuous operation specs for long livestreams.

To understand the value proposition, let’s analyze a hypothetical scene structure of SSIS-324, examining how 4K enhances each segment.
