SRT

SRT is an acronym used in several fields, and its meaning depends on the context. The most common references are to SubRip subtitle format, to Secure Reliable Transport for streaming, and to Street & Racing Technology, a high-performance automotive division.

SubRip subtitle format, abbreviated SRT, is a plain-text file format used to display subtitles in video playback. An SRT file contains a sequence of entries, each with a numeric index, a time interval in hours:minutes:seconds,milliseconds, and one or more lines of subtitle text, followed by a blank line. The format is simple and widely supported by media players and video editors, which has contributed to its enduring popularity in film and television workflows. SRT files carry no styling by themselves, relying on the player or software to render timing and text.

Secure Reliable Transport is a video transport protocol designed for reliable, low-latency streaming over the public internet. Developed by Haivision and now available as open source, SRT uses UDP with mechanisms for selective retransmission, forward error correction, and encryption. It is intended to perform well over networks with packet loss and varying latency, and it supports features such as NAT traversal and dynamic network adaptation, making it suitable for live video distribution and contribution.

Street & Racing Technology is a brand and engineering division within Chrysler, now part of Stellantis, known for producing high-performance variants of Dodge and other vehicles. SRT-branded models emphasize enhanced power, handling, and braking capabilities, and the designation has been used across multiple generations and models.

In summary, SRT commonly refers to subtitle formatting, a streaming transport protocol, or a performance automotive lineage, with the intended meaning clear from the surrounding domain.
