SMPTE digital VTR video standard, also a Sony and Bosch - BTS product D-1 format was the first major professional digital video format, introduced in 1986 through efforts by SMPTE engineering committees.

D-1 stored uncompressed digitized component video, encoded at Y'CbCr 4:2:2 using the CCIR 601 raster format, along with PCM audio tracks as well as timecode on a 19 mm (3/4") cassette tape. This article is about analog component video for the processing of color components in digital video see Digital video, Chroma subsampling and YCbCr Chroma subsampling is the practice of encoding images by implementing less resolution for chroma Information than for luma information ITU-R Recommendation BT601, more commonly know by the abbreviations Rec Videotape is a means of recording images and sound onto Magnetic tape as opposed to movie film. Uncompressed component video used enormous bandwidth for its time, and the composite D-2 system soon followed. The maximum record time on a D-1 tape is 94 minutes.
D-1 was notoriously expensive and the equipment required very large infrastructure changes in facilities which upgraded to this format. Early D-1 operations were plagued with difficulties, though the format quickly stabilized and was renowned for its superlative image quality.
D-1 is still in some usage as of 2003, and many of the technologies introduced with this format are still common to more recent digital videotape formats. Year 2003 ( MMIII) was a Common year starting on Wednesday of the Gregorian calendar.
D-1 resolution is 720 × 480 for NTSC systems and 720 × 576 for PAL systems. NTSC ( National Television System Committee) is the Analog television system used in the United States, Canada, Japan, Mexico PAL, short for Phase Alternating Line, is a colour -encoding system used in Broadcast television systems in large parts of the world
