Reducing Financial Aliasing in HDTV Production

The acceptance of high-definition technology by program producers and broadcasters will depend on financial viability as much as on specific technical parameters. This article proposes a method for operating HDTV equipment that reduces the cost, complexity, and image degradation inherent in conversion to PAL, NTSC, and 35mm film. The operating modes proposed allow simple frame-rate conversion to the local television standard without requiring temporal interpolation, and provide a single high-definition tape format that can be easily interchanged throughout the world. This offers the possibility of international hardware standardization now and enhanced-capability HDTV-only distribution in the future. Specific details of the process are discussed in relation to the SMPTE-240M standard, but the underlying principles are applicable to any of the proposed HDTV production systems.
