<p>Add HDVS as a video signal format for Sony High Definition Video System monitors (via create-page on MediaWiki MCP Server)</p> <p><b>New page</b></p><div>&#039;&#039;&#039;HDVS&#039;&#039;&#039; (High Definition Video System) is Sony&#039;s proprietary analog high-definition video signal format, developed in the 1980s as part of Sony&#039;s early HDTV production ecosystem. The format carries five separate analog signals — G (green/luminance), B (blue), R/Y (red/color difference), Pb (blue difference), and Pr (red difference) — each on its own 75Ω [[BNC]] connector, for a total of six BNCs per connection (five signals plus a dedicated sync or ground line depending on configuration). HDVS equipment supports tri-level sync, bi-level sync, and HD/VD discrete sync inputs.<br /> <br /> HDVS predates standardized analog HD component video interfaces (such as those defined by SMPTE 240M and later CEA-770.3) and was used exclusively in professional broadcast and production environments. It is not compatible with consumer [[Component (YPbPr)]] equipment.<br /> <br /> == Overview ==<br /> <br /> Sony introduced HDVS in the mid-1980s as a closed ecosystem of HD cameras, VTRs (including the HDV-1000), and monitors intended for broadcast production and high-end presentation. The system was capable of 1125-line (1080i) and 1035-line HD signals and was used extensively in early HDTV demonstrations and productions worldwide before international HD standards were finalized.<br /> <br /> HDVS monitors — including the [[Sony HDM-1230]], [[Sony HDM-1730]], [[Sony HDM-2830]], and [[Sony HDM-3830]] — accept the HDVS signal via BNC × 6 with loop-through, allowing daisy-chaining of multiple monitors from a single source. The loop-through architecture is a hallmark of professional broadcast monitor design.<br /> <br /> == Signal Format ==<br /> <br /> The HDVS signal architecture reflects broadcast engineering practice of the era, providing both RGB-domain signals (G, B, R) and color-difference domain signals (R/Y, Pb, Pr) simultaneously on separate BNC connectors, with the receiving monitor selecting the appropriate input mode via its front-panel controls.<br /> <br /> {| class=&quot;wikitable&quot;<br /> !
