Main Features The DVCAM Format The DSR-2000A employs the DVCAM format that is the professional extension of the world-wide standard DV format. Digital Component Recording for Professional Performance The DVCAM format uses 8-bit digital component recording with a 5:1 compression ratio that is identical to the DV format. It also offers a sampling rate of 4:1:1 for excellent picture quality and superb multi-generation performance. The DVCAM format has a wider track pitch of 15 µm (compared with 10 µm for the DV format) that gives higher reliability for professional editing. The DVCAM format utilizes an intra-frame compression scheme and is based on DCT (Discrete Cosine Transform) techniques with each frame consisting of 10 tracks. Each track has video, audio, ITI (Insert and Track Information) and sub-code sectors. It is the combination of ITI - a reference signal used for precise tracking - and time code on the sub-code sector that helps to assure highly accurate editing performance. Track Pattern of the DVCAM Format Playback Compatibility with All DV (25 Mb/s) Formats The DSR-2000A boasts playback compatibility with all DV (25 Mb/s) format recorded tapes. This is especially useful because home-use DV products are now widely used in professional video applications due to their compact portability and superior picture quality. For maximum versatility in a wide range of video editing environments, the DSR-2000A is designed to play back DVCAM tapes, DV tapes recorded in both SP/LP modes, and even DVCPRO tapes* without any adaptor. Moreover, it is possible to use these tapes directly as editing source material without the need for dubbing up to other formats. This unique compatibility saves time and improves productivity as it eliminates the need to use different VTRs for each format. *Not compatible with the SDTI (QSDI™) and i.LINK™ (DV In/Out) interfaces.
