The adoption of CinemaDNG among camera manufacturers appears to be hindered by Red Digital Camera’s patent US9245314, which covers in-camera recording of lossless compressed raw video. There had been an unsuccessful attempt to invalidate the patent.
- ShadowBanThis01 4y agoDJI gets around this by moving the recording circuitry outside of the camera. It's in the body of the drone, not in the camera.
- cherioo 4y agoAre you implying that is sufficient to circumvent RED’s patent? IANAL but I would argue a camera-drone is still a camera. Besides that, what you describe sounds like a decision made to reduce weight of the camera module, possibly not related to patent.

- ShadowBanThis01 4y ago"Are you implying that is sufficient to circumvent RED’s patent? IANAL but I would argue a camera-drone is still a camera." Yes, the Inspire 2 does this, and it was widely reported that this is how they dodged the BS patent. The weight distribution may also be another bonus, or vice versa. I actually don't know why there's this perception that the patent only applies to camera-internal compressed raw, because Apple/Atomos have to pay Red royalties but Atomos recorders are obviously external. But you hear it over and over.
- davemp 4y agoThe bar for novel/non-obvious seems really low if this patent has been successfully defended.
- jiggawatts 4y agoIf I remember correctly, the patent is simply compressing the RGBG bayer filter sub-pixels as separate R, G, and B images. That's almost the entirety of it, and some rubber stamper at the USPTO granted it.
- ShadowBanThis01 4y agoCompressing it using JPEG2000. You can actually decompress the image using an off-the-shelf JPEG2000 decoder.
- ShadowBanThis01 4y agoThere is almost no bar now. The USPTO is derelict, and an ignorant ruling allowed what was supposed to be illegal: software patents. Even worse is that Red simply ripped off JPEG2000 and got a patent on it. The patent "system" has become a tool for exactly what it was supposed to prevent: the theft of people's work.

- imtringued 3y agoThe only saving grace is the relatively short expiration of twenty years. if it was seventy years after the author's death progress would grind to a halt. IP expiration dates are a "brain plasticity" parameter in society. Higher values mean lower rates of change, too low values mean too high rates of change. Twenty years is a sweet spot.
