FAQ
Frequently Asked Questions
How does BlitzCast™ solve the bandwidth-latency dilemma in wireless and IP video streaming?
System architects designing networked video platforms have historically faced a strict compromise:
- High-Bandwidth Alternatives (JPEG / Uncompressed): Require 500 Mbps to 10 Gbps+, causing severe packet drops over volatile Wi-Fi/5G links.
- Standard H.264/H.265 Codecs: Fit constrained bandwidth (2–50 Mbps) but introduce 80ms to 200ms+ latency due to multi-frame buffering.
The BlitzCast™ Advantage: BlitzCast™ pairs standard H.265 compression efficiency (2–150 Mbps at 4K60) with an ultra-fast 2ms codec engine latency. This delivers sub-frame end-to-end delay over 1Gbps LAN and ~1 frame latency over standard Wi-Fi/5G.
What is the structural difference between BlitzCast™ and standard commercial H.265 IP cores?
Standard H.265 IP cores process video frame-by-frame and rely on full-frame external DRAM buffering, adding 3 to 5 frames of processing delay (~50–80ms). In contrast, BlitzCast™ uses a line-based processing pipeline that encodes and decodes video scan lines immediately as they arrive, cutting total engine latency to 2ms (encode + decode combined) while maintaining full ISO/IEC 23008-2 (HEVC) compliance.
