D-5: 1/2-in. Full Bit Rate Component VTR Format

K. Suesada, K. Ishida, J. Takeuchi, I. Ogura, P. Livingston

The D-5 VTR, the design of which is based on the D-3 format, is a high picture quality device that uses 1/2-in. tape for full-bit recording. This article deals with the need for a full-bit recording VTR and discusses in detail the signal-processing format employed by the D-5 format. In an environment where degradation-free 10-bit digital component signals are processed, it is necessary to use a full-bit VTR that is capable of 10-bit recording. To accomplish this, D-5 processes cosited luminance and color difference samples as a unit, performs 10-bit to 8-bit data conversion without truncation, and utilizes a new technique called “video randomization. ” D-5 maintains compatibility with the composite D-3 format without technical or economic compromise, while also fully exploiting the power of the 10-bit serial digital interface.
