Developed by Igor Pavlov and released in 1999, the is an open-architecture compressed archive that provides significantly higher compression ratios than traditional ZIP files. It utilizes the LZMA (Lempel-Ziv-Markov chain algorithm) , which is optimized for high-speed data decompression—a necessity for camera systems that must quickly read and unpack data into internal memory during a firmware flash. 2. Efficiency in Firmware Delivery
: High-resolution camera firmware can be several hundred megabytes; the LZMA algorithm reduces this footprint, easing the burden on manufacturer servers and user connections. s1r.7z
: Expanding internal recording capabilities, such as 4K/60p and high-speed Full HD at 180 fps. Developed by Igor Pavlov and released in 1999,
