Introduced in December 1997, it was designed to record digital video, including high-definition content, using the same higher-grade tapes as S-VHS (Super VHS), which could accommodate the increased data rates required by the format. Unlike analog-based VHS and S-VHS, D-VHS records video digitally using MPEG-2 compression and stores it in an MPEG transport stream, a format also used in DVDs and digital television broadcasts. The format was standardized by the International Electrotechnical Commission as IEC 60774-5. JVC also developed D-Theater, a proprietary variant of D-VHS used for prerecorded high-definition movies. D-Theater tapes featured studio-released content in 720p or 1080i resolution,
