Why HDCP?
What are the contents of the sector, all channels of distribution – the-air signals or Blu-ray or HD-DVD, HDTV and cable and satellite should be backed up.
Now, if HD digital DVI and HDMI is the best video quality currently available are provided. As for the end user, is also ideal for counterfeiters to use the DVI or HDMI, to achieve a perfect video signal.
And 'thethe story of the birth of high bandwidth Digital Content Protection – HDCP known.
HDCP is in three stages – authentication, encryption and distance – based process control video transmission and delivery at the end of the process of video playback.
Technically, HDCP is pure, without protection against copying, restrictions on the reproduction, distribution, etc. must be handled by another process in the signal chain, for example, satellite television and cableBoxes, DVD players, HDTV, etc. What protection bandwidth for digital content not only to ensure that, regardless of content restrictions exist, they are enforced by authenticating the sender and recipient.
Interoperability HDCP
One possible source requires an HDCP compatible DVI or HDMI with HDCP for the recipient to transfer high definition content. In addition, all active components of the chain connectivity to high definition televisionshall comply with HDCP, otherwise it would be possible to enjoy high definition content.
You might think, you can still continue to enjoy broad definition content in the way that high, so we have – even if "old HDTV is its not compatible with HDCP, but .. .
It 'true that most of the containers to prevent high-definition support, even a whole day in high definition component video, but the creation of pirate copies of high resolution, HDCP-compatible products banConvert the HDCP protected content such as analog high resolution – unless this is expressly permitted by the content provider.
What does this mean?
Connect a HDCP source like an HD-DVD or Blu-ray, the recipient can not complain – at best – Force resolution video source device to convert analog outputs for connecting to standard DVD quality, as well as DVD content -Audio, DAT quality on non-HDCP compliant digital audio limitsOutputs. In the worst – what you get is a jack white!
In other words, if you want to be sure you'll always be able to enjoy the benefits of Full HD content on TV or monitor display device must support HDCP.
Why HDCP nightmare, "the largest for the first HDTV?
Be HDCP involves the use of a digital interface – in particular the use of DVI and HDMI inputsOutputs. Simultaneously, a DVI or HDMI does not necessarily imply HDCP compatibility. Several large producers have emerged in the early years of the DVI and HDMI, with products that are not compatible with HDCP.
Part of the reason for this anomaly is that, until recently, HDCP is not required. Indeed, protection of digital content, which was adopted by the FCC almost a year after the Protocol has begun to see the shelves first HDMI-compatible, and ifDVI after about a number of years.
The party is currently a serious problem that most of the first applications HDTV face – they ended up paying top dollar for HDTV first hit the market. Television can really represent high-definition content, but lack of HDCP-compatible HDMI (or DVI) digital inputs interact with the latest generation of high definitionand HD-DVD and Blu-ray.
The end result is that it is possible for HDTV High-definition content Clock on it. In addition, What you get is a modified version of the image in high resolution via component video output is the fourth Max Resolution 1920×1080 HD.
This transformation in the image on the analog outputs are used by a special numeric indicator – Image Constraint Token (ICT) – Digital RightsManagement standards, but is used to protect movies from unauthorized copying. The decision of this flag, the output from the release of the video player or Set-Top-Box component is the prescribed period of study or content, which may decide the application of ICT in a hard drive or a floppy disk left content .
Fortunately, there is a bright spot in this cloud of confusion. Content providers are aware of the difficulties of implementing HDCP onfundamentals of electronic current. In an attempt to show HDTV this willingness to respond to some consumers – half way – until they upgrade their computers, some studies have suggested publicly that the conversion is not consistent with that analogy. Sony Pictures Entertainment has stated publicly that it is not the Blu-ray lead, said ICT, and some studies have shown that follow suit. This means that at least part of the first Blu-ray is completely visibleHD resolution for all HDTV owners. Universal Studios also said that for now, it will download the content of the sample HD-DVD discs.
Note that follows all content providers in the footsteps of Sony and Universal. For example, Warner Pictures – a defender of Technology – is said to run down-conversion "at least" a number of its initial HD-DVD. Moreover, studies that do not applyICT is not obliged to maintain its current position for an indefinite time to see so do not be surprised ICT implemented across all sectors in recent years – especially after the format war between Blu-ray HD-DVD is over there, and equally important when the penetration of HDTV compatible reached the appropriate level.
Statement
We believe that owners of high definition televisions failed yet able to get many years of enjoyment to their game -In other words, there is no reason to hurry and update it. This means that you have enough time planning to upgrade to HDTV, but …
It should be noted that the requirements for ICT projects and new devices that only one output HDCP / HDMI, over time, the resources it can convert your old town HDTV a waste! If in the process, do not upgrade your computer, you can do with an HDTV is useless when it comes to watching HD content!
