Every digital medium needs copyright protection; however, the process is not easy. Media companies use different ways to prevent unauthorized access to their protected data, and one such method is HDCP.<\/p>\n\n\n\n
Large media houses use HDCP as the standard to protect their critical and expensive media content. Let\u2019s get into HDCP\u2019s details and what you need to do to watch HDCP-protected content.<\/p>\n\n\n
HDCP stands for high-bandwidth digital content protection and is a digital copy protection that prevents users from copying digital copyrighted audio\/video content while it crosses various connections.<\/p>\n\n\n\n
Devices like Blu-ray players or cable boxes scramble video content before sending it to your television. <\/p>\n\n\n\n
If you want to receive these signals, the content must be descrambled, which the TV does by exchanging codes with players.\u00a0<\/p>\n\n\n\n
So, if you want to watch any motion picture, your devices must comply with HDCP. The requirement is not only confined to TVs and movie players. <\/p>\n\n\n\n
If you use a non-compliant splitter, wireless transmitter, tuner or audio-video receiver in a complex home theater system, it won\u2019t support HDCP.<\/p>\n\n\n\n
You must know that HDCP becomes essential only when the TV programs come from a company that uses this protection. <\/p>\n\n\n\n
Most companies, including Sony, Disney, Warner, etc., have already incorporated HDCP into their content. <\/p>\n\n\n\n
You must have the right equipment to watch shows from these companies; otherwise, you will see an arrow message or a blank screen.<\/p>\n\n\n
All HDCP-compatible devices have a particular set of encryption keys that these devices exchange while trying to transmit HDCP-protected content between two devices. <\/p>\n\n\n\n
These encryption keys confirm that both exchanging devices are HDCP compliant and encrypt the content during transmission. <\/p>\n\n\n\n
The content is again decrypted before it reaches another end. As a result, no one can attack the content and the signals during transit.<\/p>\n\n\n\n
Earlier, HDCP supported only devices to display the transmission of protected content; however, after HDCP 2.0, all its versions also supported network transmission. <\/p>\n\n\n\n
As a result, it is possible to connect different HDCP devices with different networking hardware, such as routers, switches, and repeaters. <\/p>\n\n\n\n
However, all networked systems must support the same HDCP standards for successful transmission in these device-to-device connections.<\/p>\n\n\n
A device becomes HDCP compliant if its manufacturer has a license from Digital Content Protection, an Intel Subsidiary that handles the licensing process of HDCP. <\/p>\n\n\n\n
The devices must meet the standards and specifications to receive a license from the company. <\/p>\n\n\n\n
Also, the device manufacturer pays an annual license fee and promises not to transmit any HDCP-protected content to non-HDCP-compliant devices. <\/p>\n\n\n\n
As several big media houses support HDCP, getting the license for all source devices and display becomes mandatory.<\/p>\n\n\n\n
You can check whether your device is HDCP compliant by its specifications in the manual or on the manufacturer\u2019s website. <\/p>\n\n\n\n
Alternatively, the feature has become so common that you may find it on the device box.<\/p>\n\n\n
HDCP is a digital technology that depends on HDMI and DVI cables. Thus, acronyms such as HDMI\/HDCP or DVI\/HDCP are often grouped.<\/p>\n\n\n
HDMI\/ High Definition Multimedia Interface is a digital interface allowing your HDTV to deliver the best possible digital picture in uncompressed form. <\/p>\n\n\n\n
HDMI was created by the electronic industry giants, including Sony, Toshiba, Hitachi, Matsushita, and Thomson; thus, it has vast support for the motion picture industry.<\/p>\n\n\n\n
DVI\/Digital Visual Interface is an older interface for digital pictures developed by the Digital Display Working Group. With the introduction of HDMI, DVI has become obsolete due to the advantages of HDMI over DVI. <\/p>\n\n\n\n
The significant benefits of HDMI over DVI are:<\/p>\n\n\n\n
There is nothing like HDCP-compliant cable, as HDCP compliance only applies to the devices. In other words, all HDMI cables available are HDCP compliant. <\/p>\n\n\n\n
You may see HDCP labels on some HDMI cables, but this is only for advertisement. You can use any HDMI cable to connect two HDCP-compliant devices.<\/p>\n\n\n\n
It\u2019s a device that has embedded HDCP technology. HDMI connector pins have nothing to do with HDCP as they do not have any design that can detect or transmit HDCP. <\/p>\n\n\n\n
The only feature you must consider while choosing HDMI cable is the high-speed certification.<\/p>\n\n\n
A decade ago, in Feb 2013, another version of HDCP. i.e., HDCP 2.2 was introduced to protect 4K UHD media during HDMI transmissions. <\/p>\n\n\n\n
The version is not backward compatible, so you will need a device that supports HDCP 2.2 version as supported by the transmitting device to display 4K content<\/a>.\u00a0<\/p>\n\n\n\n An important consideration with the HDCP 2.2 version is that it is incompatible with regular HDMI cables like earlier. <\/p>\n\n\n\n These cables only support 720p pixels and 1080i max transfer resolutions. <\/p>\n\n\n\n You need high-speed HDMI cables for transmitting data in HDCP 2.2-compliant devices for smooth transmission.<\/p>\n\n\n\n
