The development of a practical VTR that is compact, inexpensive and offers high picture quality has been pressing requirement Comparing present HDTV VTRs (1-in. digital VTR and UNIHI VTR etc.) with current conventional-definition television (CDTV) VTRs used in broadcasting, there is much room for improvement in terms of cost (VTR & tape), function and performance, mobility and maintenance for practical use. To solve these problems at an early stage, we have developed an HDTV VTR using a 1/2-in. tape cassette by making effective use of a current CDTV digital VTR (D-5 VTR) and applying bit rate reduction technology.
