HDCP landed in the MacBook problems
For years that are HDCP protection, Apple was the impasse over. Now, the new MacBook and MacBook Pro, this protection is present, but it falls a bit like a hair in the soup for users.
The HDCP (High-Bandwidth Digital Content Protection) was developed by Intel to protect stream multimedia (audio and video) on routes DVI, HDMI and DisplayPort. It enables compliance with the DRM and is predominantly found in the readings of high-definition content from HD-DVD and Blu-ray. The HDCP chain is therefore the source until the arrival which is the screen itself. Between the two extremes, all elements must be HDCP compatible with the risk of breaking the chain and therefore not able to read the contents (or deteriorated in quality).
Apple has integrated HDCP in its recent MacBook and MacBook Pro, and those that have reported have learned mostly at their expense. So Ars Technica tells the story of a professor who wished to distribute Hellboy 2 in his class. The film had been legally obtained on iTunes (USA) and had in fact protected. However, the teacher connected a VGA adapter on its DisplayPort to link together on a video Sanyo.
The overhead projector was not compatible and, even though the VGA is not either. Suddenly, the rocker a little irony, because the screens sold by Apple does not at all support HDCP. To play protected content, we need a TV or a compatible device is connected, but very few are equipped with the DisplayPort is the HDMI that is found almost systematically. So how? Apple does not sell DisplayPort to HDMI adapter, then it must first connect an adapter DisplayPort to DVI and a DVI to HDMI other?
The video playback was not a problem until now, but recent films added to iTunes recognize the protection HDCP. As a result, a user simply connects an external display in its MacBook must not only have an adapter for DVI or VGA, but denied playing his film if his screen time a little.
As shown in the official forum of Apple, those who bought a screen 30-inch Cinema Display do not take the news with great philosophy, especially that Apple has never talked about this change in size its policy.
