In connection with this significant change, our company has implemented a new functionality in the Smart Air post-air analytics system. In addition to the main functionality, we have added the ability to calculate the duration of subtitles within a single broadcast day. Transcription and visualization of subtitles, which is performed in the system along with recording video and audio, allows you to control the quality and volume of broadcasting programs with subtitles and provides additional features for searching and indexing recorded programs.
