Development and conditions of an HDTV multimedia system

The development of an HDTV (high-definition television) multimedia system for use in home information terminals is described. It displays multiple incompatible images, such as MUSE (multiple sub-Nyquist sampling encoding), NTSC (National Television System Committee), and CG (computer graphics), on the same screen at the same time. It records the created, processed, or displayed images. High-quality MUSE images can be converted to NTSC images and recorded on conventional VCRs. Display interfaces are provided for various display units used in personal computers and in the NTSC system. The use of optimized chip sets makes the system compact and inexpensive, solving the problems of cost, size, and compatibility.<
