TOD is a file format that is not widely used. TOD videos are usually captured by JVC cameras. It is a high-definition format that uses transport stream for video data. TOD files cannot be directly played on consumer video equipment. They must be converted or repacked into one of the widely adopted distribution format.

Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end ARM3 processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.
