Excerpt:<\/strong> The starting point is a Pioneer DV-717, an early high-end DVD player from the pre-HDMI era. Rather than connecting it directly to a television, its analog video output becomes the input to a dedicated PC-based video processing system.<\/p>\n\n\n\n The particularly interesting connection is the player’s RGB-capable SCART output. Instead of allowing the signal to be converted to composite or S-Video, the RGB signal is captured directly by a SoftLab-NSK FD332 professional capture card.<\/p>\n\n\n\n The resulting chain is:<\/p>\n\n\n\n Pioneer DV-717 \u2192 SCART RGB \u2192 FD332 \u2192 PC \u2192 video processing \u2192 4K display<\/strong><\/p>\n\n\n\n This is not simply an attempt to make an old DVD player look modern. It is an experiment in preserving as much of the original analog video information as possible and then applying processing that the original player could never perform.<\/p>\n\n\n\n A European SCART connection can carry RGB with separate R, G and B signals and synchronization. This is fundamentally different from composite video, where luminance and chrominance are encoded together.<\/p>\n\n\n\n For a retro video experiment, that makes RGB particularly valuable. The FD332 is capable of accepting analog RGB directly, so the DVD player’s RGB output can be digitized without first passing through another composite or S-Video encoding stage.<\/p>\n\n\n\n That gives us a useful comparison:<\/p>\n\n\n\n SCART RGB \u2192 FD332<\/strong><\/p>\n\n\n\n rather than:<\/p>\n\n\n\n SCART \u2192 composite\/S-Video \u2192 capture<\/strong><\/p>\n\n\n\n The latter would introduce another analog video encoding\/decoding stage before the PC even begins processing the image.<\/p>\n\n\n\n A PAL DVD is only 720\u00d7576 interlaced video. Simply enlarging that to 3840\u00d72160 does not create new detail.<\/p>\n\n\n\n The real processing challenge is what happens before scaling.<\/p>\n\n\n\n The PC can determine whether the material is genuinely interlaced video or originated from progressive film material. For motion video, a good motion-adaptive deinterlacer can preserve the 50-field-per-second temporal information and produce 50 progressive frames per second. For film-derived material, field analysis can instead reconstruct the underlying progressive frames.<\/p>\n\n\n\n Only after that reconstruction does the final upscale take place.<\/p>\n\n\n\n A conceptual pipeline is therefore:<\/p>\n\n\n\n 720\u00d7576i \u2192 field analysis \u2192 deinterlacing\/film reconstruction \u2192 processing \u2192 3840\u00d72160<\/strong><\/p>\n\n\n\n This is considerably more meaningful than simply applying a large resize operation.<\/p>\n\n\n\n The capture PC does not need to be a modern machine.<\/p>\n\n\n\n A Core 2 Quad Q6600 is capable of handling the relatively modest PAL-resolution input, particularly if the processing is divided between CPU and GPU. A Radeon RX 550 can perform the GPU-side shader work, allowing the system to experiment with real-time deinterlacing, sharpening and scaling without requiring a powerful modern processor.<\/p>\n\n\n\n The goal is therefore not maximum computational complexity. It is a low-latency, real-time legacy-video appliance<\/strong>.<\/p>\n\n\n\n A lightweight version can perform:<\/p>\n\n\n\n More computationally demanding reconstruction can be reserved for a completely separate modern PC.<\/p>\n\n\n\n The more ambitious version uses the modern gaming\/AI PC containing an RX 9060 XT.<\/p>\n\n\n\n The capture PC sends digital frames over the network to the modern PC. The RX 9060 XT performs much heavier processing or AI-based super-resolution and returns the processed frames.<\/p>\n\n\n\n Because the two PCs are connected by a fast Ethernet link, PAL video can be transported without introducing another lossy video codec into the processing chain. At 720\u00d7576 YUV 4:2:2, the raw video data rate is only around 166 Mbps at 25 frames per second.<\/p>\n\n\n\n The architecture becomes:<\/p>\n\n\n\n DV-717 \u2192 FD332 \u2192 capture PC \u2192 Ethernet \u2192 RX 9060 XT \u2192 Ethernet \u2192 capture PC \u2192 display<\/strong><\/p>\n\n\n\n This makes the old PC a capture\/output appliance and the modern PC a remote video-processing engine.<\/p>\n\n\n\n Audio is treated as part of the same A\/V pipeline rather than being sent directly from the DVD player to the amplifier.<\/p>\n\n\n\n The DV-717’s analog stereo output can be captured alongside the video. The video and audio are assigned timestamps, allowing the processing PC to compensate for the latency introduced by deinterlacing, scaling or remote GPU processing.<\/p>\n\n\n\n The player’s S\/PDIF output could also be captured if preserving the original digital audio stream is preferable. The important point is that synchronization should be based on timestamps and a common timeline, rather than assuming that two independent physical paths will remain synchronized.<\/p>\n\n\n\n The DV-717 is only the beginning.<\/p>\n\n\n\n The same hardware can be used to investigate other legacy video sources:<\/p>\n\n\n\n Some of these are particularly interesting because their sources are genuinely analog. LaserDisc and S-VHS, for example, allow the capture system to process an analog signal that has not originated as a digital video file.<\/p>\n\n\n\n The project therefore becomes less about “upscaling a DVD” and more about what can be achieved when modern digital processing is inserted into the signal path of legacy video equipment<\/strong>.<\/p>\n\n\n\n None of these components were designed for this exact job.<\/p>\n\n\n\n The DV-717 was designed to play DVDs.<\/p>\n\n\n\n The FD332 was designed as a professional video capture\/processing board.<\/p>\n\n\n\n The Q6600 is an obsolete general-purpose CPU.<\/p>\n\n\n\n The RX 550 is an inexpensive legacy GPU.<\/p>\n\n\n\n The RX 9060 XT is a modern gaming\/AI GPU in another room.<\/p>\n\n\n\n Yet together they can form something none of the individual devices provides: a modern video-processing system for legacy analog sources<\/strong>.<\/p>\n\n\n\n The interesting part is not replacing the old hardware.<\/p>\n\n\n\n It is finding a job for it that the original designers never imagined.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" What happens when a high-end old DVD player, a professional analog capture card, and a modern GPU are combined into a video pipeline they were never designed for?<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"project","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-157","post","type-post","status-publish","format-standard","hentry","category-projects"],"_links":{"self":[{"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=\/wp\/v2\/posts\/157","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=157"}],"version-history":[{"count":1,"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=\/wp\/v2\/posts\/157\/revisions"}],"predecessor-version":[{"id":158,"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=\/wp\/v2\/posts\/157\/revisions\/158"}],"wp:attachment":[{"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=157"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=157"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/offlabelhardware.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=157"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
