Efficient Transmission of Digital Component Video
This article discusses two basic approaches to the efficient transmission of digital component video. The first includes sub-Nyquist sampling, DPCM encoding, and decoding with comb filter reconstruction. The second approach utilizes sample interleaving, DPCM encoding, and digital interpolation reconstruction. Other techniques, such as sliding scale quantization, luminance bounding of the chrominance, line-sequential chrominance, and video transmission during the normal blanking interval can be applied to either approach to help reduce the transmission rate to the DS3C (approximately 90-Mbit/sec) or even to the DS3 (approximately 45-Mbit/sec) level of the North American digital hierarchy. A number of implementations that can deliver high-quality component transmission at either 90 Mbits/sec or 45 Mbits/sec are described.
