What is the use of the DAC-40s inside of a SE-1000?
A DAC-40 is a one way (HD) SDI to (HD) analogue converter. The DAC-40 can take ANY SDI signal (576i, 720P, 1080i) and convert it into ANY analogue format (576i, cvbs, 576i YUV, or 720P HD-YUV or 1080i HD-YUV). Example 1: Input HD-SDI 1080i (using an HD camera on the HD –SDI input). Output in 576i Cvbs to TLM433 Example 2: Input SD-SDI 567i (using standard definition SDI camera).
