The EIA/CEA-861-B standard has the first 34 short video descriptors above. It is used by HDMI 1.0–1.2a.
Some devices do not need to receive non-broadcast messages and so may use address 15 permanently, notably remote control receivers and HDMI switches. Devices which need to receive addressed messages need their own address. A device obtains an address by attempting to ping it. If the ping is unacknowledged, the device claims it.
The HDMI specification is not an open standard; manufacturers need to be licensed by HDMI LA in order to implement HDMI in any product or component. Companies that are licensed by HDMI LA are known as HDMI Adopters. [88] DVI is the only interface that does not require a license for interfacing HDMI. [citation needed]
Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. [1]
A source has only an HDCP/HDMI transmitter. [4] Sink The sink renders the content for display so it can be viewed. Examples include TVs and digital projectors. A sink has one or more HDCP/HDMI receivers. [4] Repeater A repeater accepts content, decrypts it, then re-encrypts and retransmits the data.
HDMI lacks VGA compatibility and does not include analog signals. DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics. In addition to digital video, HDMI supports the transport of packets used for digital audio.
Locking of the serial number was first documented in 2015 on the iPhone 6, which would become inoperable from a detected replacement of the "home" button. Later, some functionality was restricted on Apple and Samsung smartphones when a battery replacement not authorized by the vendor was detected. [370] [371]
