A telesync (TS) is a bootleg recording of a film recorded in a movie theater, sometimes filmed using a professional camera on a tripod in the projection booth. The main difference between a CAM and TS copy is that the audio of a TS is captured with a direct connection to the sound source (often an FM microbroadcast provided for the hearing-impaired, or from a drive-in theater). Often, a cam is mislabeled as a telesync.
