One of the methods used, yet sometimes complicated and expensive, is by converting the signal for example to VGA, Component or Composite video. Methods to Remove HDCP from HDMI Convert to Analog Naturally a “HDCP remover” or “HDCP Stripper” device is not readily available to the public … or is it?

Non compliant devices, an old (HDMI) TV for example, will simply display a message that the content cannot be displayed or will display a blank screen. Just like those idiotic region codes of DVD’s and BluRay’s.

Even though the master key for decryption has been compromised since 2010 and some smart folks assembled a device for demonstration purposes, HDCP is still in full use.

The video sources asks for the secret code from the destination device, before it sends content, so the receiving party is authorized and can decrypt.

HDCP uses authorization and encryption – it verifies (authenticate) the receiving party (Destination or “input”) – i.e. See it as the digital counter part of MacroVision as was used with analog video way back in the day. The content, or content source (where the “output” comes from), determines if HDCP is needed, and is/was intended to prevent content to be displayed or recorded by unauthorized devices. The first HDMI versions did not include HDCP, but most modern HDMI capable devices support it. HDCP is a copy protection that was added to the HDMI standard, at a later time, by Intel. HDMI and HDCP – Some background information So I’m looking at older HDMI LCD/LED/Plasma TV’s, HDMI Projectors, Game Recording (PS3), taking screenshots for documentation and/or articles, and of course my own little project to generate ambient light behind my TV! Please keep this in mind. Please note that I’m not writing this article to promote pirating content! This article is solely aimed at using non-HDCP compliant equipment with equipment that seems to require HDCP. The downside of that project is that it only works for a dedicated HTPC running for example Kodi (XBMC).īut what if I’d like to see this with video from my XBox 360, XBox One, Wii, or … Blu-ray player or cable box?īesides the fact that we need to grab this video, and all it’s technical complications, we will be running into a copy protection issue called HDCP, a HDMI feature nobody really asked for.

Speaking of the Time Sleuth, Epos uses both that device to test the HDMI signal’s lag, as well as NVIDIA’s LDAT test kit to verify the total lag when PC gaming.I’ve been playing with ambient light for my TV for a while now, as you can see in the “ Ambient TV lighting with XBMC Boblight, OpenElec and WS2811/WS2812 LEDs“, to make colorful lights (LEDs) light up matching the video you’re seeing on your TV. I’ve personally tested some knockoff “gaming capture devices” that add over a frame of lag (around 16.5ish ms) simply by using the passthrough! Either test yourself with a Time Sleuth, or check EposVox’s channel for a review.

Just because your capture card claims it’s for gaming and has an HDMI passthrough, doesn’t necessarily mean it’s a zero-lag passthrough.

Playing games on your PC through a capture card is a completely different story and can add from two to ten frames of lag! EposVox also tests this in other videos, but it’s generally not something I’d recommend for games designed in the zero-lag analog era:.

Only light guns and active shutter 3D glasses sync to sub-ms timings, but they only work on CRT’s anyway. EposVox is clear about this in the above video, but in case you were only half-listening, I wanted to reiterate the point (hence the * above): In the context of gaming on flat-panels, less than one millisecond should be considered “zero lag”. Not sure which is which? As usual, The Stream Professor has us covered. Most of the time, “gaming capture cards” have an HDMI passthrough that only add a *sub-1ms amount of latency and even ones that add more can usually be fixed by using an HDMI splitter.

One interesting issue people sometimes run into, is lag added while streaming, due to capture card passthrough. Lag is something we discuss quite often in the world of retro gaming, but lag is a problem for gamers of all generations.
