dtsub

dtsub is a term encountered in several technical contexts but does not denote a single, universally defined technology. In media processing and video workflows, it is sometimes used informally to refer to a subtitle substream or track associated with digital video. Because there is no widely adopted specification, implementations vary: some tools store subtitle data directly in a container and label it as dtsub, while others treat it as a vendor- or project-specific convention. The lack of a standard means encoding methods, timing, and synchronization for a dtsub stream are not fixed.

In software development and localization workflows, dtsub can appear as an internal project name or as a shorthand for a dynamic text substitution feature within a runtime environment. In these cases, dtsub is not a formal standard and its meaning is defined by the project that uses it. Instances found in code comments, configuration files, or build scripts should be interpreted with caution and cross-checked against project documentation.

Because the term spans distinct domains, the best approach to determine what dtsub refers to in a given context is to examine the surrounding materials. Look for file extensions, toolchain references, or vendor documentation that accompany the term. If ambiguity remains, consulting the source or maintainers is advised to avoid misinterpretation.
