About formats

MJPEG (Motion JPEG) is a video compression format in which each frame is independently compressed as a separate JPEG image. Unlike interframe codecs that exploit temporal redundancy between successive frames, MJPEG treats every frame as a standalone photograph, applying the discrete cosine transform compression familiar from still image JPEG encoding. This approach dates back to 1992, coinciding with the establishment of the JPEG standard itself, and was widely adopted as one of the earliest practical methods for compressing digital video. The intraframe-only nature of MJPEG carries several practical benefits: any frame can be accessed and edited independently without decoding neighboring frames, making it exceptionally well-suited for video editing and applications requiring frame-accurate random access. MJPEG is commonly used in IP cameras, security surveillance systems, medical imaging, and industrial machine vision, where individual frame integrity and low processing latency outweigh the higher bandwidth requirements compared to modern interframe codecs. The format achieves typical compression ratios of 10:1 to 20:1 while maintaining good visual quality, though at significantly higher bit rates than temporal compression methods for equivalent quality. MJPEG streams can be delivered over HTTP, making them straightforward to implement in web-based monitoring applications, and the simplicity of the codec ensures reliable decoding even on resource-constrained embedded hardware.
Initial release: 1992
GSM 06.10 (Full Rate) is the foundational speech codec of the Global System for Mobile Communications standard, ratified by ETSI in 1991 and deployed across hundreds of cellular networks worldwide. Operating at a fixed 13 kbit/s, the algorithm applies Regular Pulse Excitation with Long-Term Prediction (RPE-LTP) to compress 20 ms frames of 8 kHz mono speech into just 33 bytes each. This approach models the vocal tract as a linear predictive filter, encodes the excitation signal, and leverages pitch periodicity for further reduction — tuned to deliver intelligible voice under the bandwidth constraints of early digital mobile channels. The codec powers not only GSM telephony but also many VoIP applications, voicemail systems, and IVR platforms that benefit from its low bitrate. Three concrete advantages stand out. First, extraordinary compression: one minute of speech fits in roughly 100 KB, enabling efficient storage and transmission. Second, universal tooling — libraries such as libgsm and SoX handle encoding and decoding on every major platform. Third, a royalty-free patent landscape that has encouraged adoption across open-source telephony projects like Asterisk and FreeSWITCH.
Initial release: 1991
