Now that digital broadcasting service areas are expanding, and with the appearance of high-definition content on Blu-ray and HD DVD media, there is a strong demand for high definition content production. Until these recent developments, HD content production had been comparatively simple, with the source of input being mainly limited to HD camera recordings. With television shifting to high definition and the rapid spread of high-definition video cameras for consumer use, location shooting in co

The figure shows image samples and waveforms after the original video has been converted to HDV/DV format using the VC-300HD and then, again using the VC-300HD, converted to HD/SD-SDI output. In the conversion from HDV, once the MPEG2 decoding has been done, the scaler carries out processing to magnify or shrink the image. In the 1080i output, you can see that the HDV characteristics are output more or less unaltered. 9
