MF700 Series SSW700 SDI 2x1 Seamless Switcher The 2x1 Seamless SW’er card for HD/D1 is designed for the MF-700/NOIF-3000 Frame (both 3RU and 1RU). It detects errors in the HDTV/SDTV signals based on the SMPTE292M and 259M-C standards and seamlessly switches between the current/backup circuits. SDI 2x1 seamless SW’er HD/SD-SDI INPUT BUF S/P BUF S/P HD/SD IN1 HD/SD IN2 HD/SD-SDI OUTPUT VIDEO SELECT ERR DET HD/SD OUT1 HD/SD OUT2 P/S HD/SD OUT3 2x1 Seamless SW’er Front & Rear Card Features SDI Signal Monitoring Automatic Delay Compensation The two channels of the SDI input signals are constantly monitored It is possible to absorb the difference in transmission delay between for errors. the current/backup circuits and re-align the video signal phase. Seamless Automatic Switching Emergency Bypass When SDI signal error occurs, this card can automatically perform Bypass between SDI input and output during power outage or by uninterrupted switching between the current /backup circuits. manual operation is possible. Manual switching is also possible. In addition, there are two error sensitivity levels (High Sensitive and Low Sensitive) that can be chosen from. Installable in MF-700/NOIF-3000 Common Frame Up to 14 cards can be installed in each of the MF-700 and the NOIF3000 Frame and it can co-exist with other converter units and E/O, O/E cards from the MF-700 Series. NEC Corporation http://www.nec.com/global/prod/nw/broadcast/ E7 SSW700 SDI 2x1 Seamless SW’er Feature Switching, Distribution Takes SDTV SDI (SMPTE259M) or HDTV SDI (SMPTE292M) signals as inputs and after 2-to-1 seamless switching, signals are distributed as 3 outputs. Error Detection The two input channels are constantly monitored for errors. Channels can be switched automatically when either the 1Bit error (High Sensitive Mode) or TRS continuous detection (Low Sensitive Mode) error is detected. Automatic Delay Compensation The transmission delay time differences in the two input channels can be automatically corrected up to ±1 field.
