If you know or should know that my specification, technology, or product is covered by your patent, you must tell me what patent covers it and why. Specifically, require patent holders to notify infringers of their infringement in a timely manner. Codec patents, for example, should never have been valid.

Make it clear that math, in any form, is not patentable. Decrease patent terms to just a few years in most fields.

I think that evidence that patents are beneficial in any field is lacking.Īlternatively, a few major reforms would help. MPEG-LA is just a symptom of broken IP law just as much as patent trolls and the Eastern District of Texas getting parks built by global corps are. (that being said, if MPEG-LA wasn't around, someone else would have formed just as evil a patent tyrant company to act as the arm of big media). Ain't the world such a better place for MPEG-LA existing. Ah yes, the sweet taste of abusing state institutions to hold back scientific progress.įirst it was efficient video and audio compression, now it will be life saving treatment. This is very much the same thing as with medication, you have brand name medication which is pricy, patent expires and much cheaper versions enter the market, but even then you can still purchase the brand version and pay more. What expired patent means is that anyone else can implement their encoder/decoder legally, so perhaps future raspberry pi will have different implementation of the decoder that doesn't require keys. And if raspberry would have to provide these keys they would have to break their security scheme which would still be like breaking DRM. And there's nothing preventing them for charging for their decoder if people are willing to pay for it.

I believe the codec is part of most distros as it's just a few Kb, but without licensing it's essentially useless.
#MPEG 2 DECODER RASPBERRY PI LICENSE KEY#
To expand on the 'what is it' point: What you're buying is a license key that the codec itself requires be present before accepting or working on any audio or video stream sent to it.
#MPEG 2 DECODER RASPBERRY PI INSTALL#
Considering how cheap it is for individual licenses and the very tinkerer nature of RPi itself, it made more sense to ask users to purchase single device licenses, install them manually and probably save everyone some money overall. However while this is fine for Microsoft and the like, it would have gone easily into the multi-thousand-pound range as all they can give is estimated sales and that would have pushed up prices of the unit itself. To expand on the price point: The Raspberry Pi foundation could have opted for a volume license for all Raspberry Pi devices to be licensed from the get go. Vlc has no access to this video decoding hardware if it's locked, so must use the CPU. However, as rcxdude mentioned, those decoding algorithms are not free, and is controlled with a license key. Luckily, because its chip is intended for video oriented set top boxes, it contains a decent GPU that is capable of decoding HD video in the three main video formats used today.

The RPI has a really slow processor, so is even less capable of decoding video itself, known as 'software rendering'. This means they're better suited to drawing video or 3d scenes, where it's usually possible to divide the picture up into pieces that can be processed in parallel. Graphics processors, or GPUs, have many times more cores than CPUs, but they're a lot simpler. Even modern fast CPUs struggle to decode HD video in real time, so modern graphics cards have the ability to do it instead.
