For a short period of time Sony added a series of very special Betamax models to their regular lineup. Known as Extended Definition Beta these VCRs pushed the luminance signal (sharpness) so high that conventional tape couldn't handle the frequencies. Special metal tape had to be used to enjoy ED Beta. These units were also backward compatible and would also recorded great in SuperBetahi-fi. When it comes to making copies the ED Beta units are the kings. They still have the conventional composite video in and out (the yellow phono plug) but added S-video. Something reserved for only the very highest performing Betas. S-video ups the game when it comes to making copies (and with these machines you wanted to do precisely that). The ED Beta recorders do over 550 lines of resolution, which matched the broadcast standard of the day. To transfer this high flying signal best from one recorder to another Sony incorporated S-video line receptacles (sockets) and cables. With S-video luminance and chrominance (color) are given separate lines. Carried in this manner the signals can be cleaner and stronger. They suffer less from the crosstalk that can occur when using the conventional composite out. All ED Betas have S-video sockets with four pin receivers inside. There where five ED Beta models marketed to North America. They were the EDV-9500, EDV-7500 and the EDV-9300 and EDV-7300 (in Canada) and the EDW-30F (professional sports edition). Not too long after ED Beta Sony released the SL-HF2100. It is a space age design Betamax featuring a unique touch panel system (no buttons). It sported an advanced five stage color filtering system and improved picture performance when recording using the Super Hi-Band 6.0 MHz s speed. Sony thought this VCR deserved the S-video treatment so it became the only non-ED Beta unit to have them. You can click on the model numbers above and the first page for that unit will be presented in the center of the browser window. You will be able to go back to the previous page. Connecting the S-video and audio cables are pretty straight forward. In the example bellow two EDV-9500 VCRs are being interfaced together as an editing pair. The player exports the signals to the recorder. Picture loss and noise on all lines is less because they are being sent separately. See graphic below:
