Background:
As the market for high definition television continues to heat up, consumers must be educated on the latest technology. One of the terms that you, the consumer is likely to be encountered in selecting a HDTV set is: HDMI. For most it is a term unknown to explain the details of HDMI in this article for you, the consumer, is armed with sufficient knowledge to make smart purchasing decisions.
What is HDMI: HDMI stands for High Definition Multimedia Interface. The HDMI specification (now 1.2) has been created by some of the largest manufacturers of consumer electronics in the world: Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson and Toshiba. HDMI is the latest digital HDTV standard interconnection. The notable differences between HDMI and more earlier HDTV interconnects standards (component video and DVI) are:
HDMI is digital unlike cables component analog video
HDMI supports multiple audio channels and digital video. (Only compatible with the DVI digital video)
– HDMI is more compact and carries the audio and video signals therefore eliminate cable clutter.
HDMI includes content protection called HDCP content protection (HD)
What it looks like an HDMI: HDMI looks like a USB cable. The compact size and high integration (carries both audio and video) makes the HDTV installation experience truly "plug and play.
Why use HDMI:
HDMI is digital, so picture quality is "perfect" from source to screen
HDMI is all digital audio and video connection. This will minimize cabling system
HDMI is quickly becoming the de facto standard for connections to high definition.
How is the transport of digital video HDMI: HDMI video is made by 3 separate differential pairs. Each pair of carriage 1 of 3 Native uncompressed digital R, G, B signals (source DVD player, set top box) to the sink (HDTV display). A unique protocol, TMDS (minimized differential signaling), is used to transport digital data. Each pixel is represented by 24 bits (8 bits for each primary color). The TMDS protocol then "calculates" and cloth extra 2 bits for the flow of data to create a digital workflow with minimum transitions (lower EMI, Low-interference) and also minimize long strings of '1 'and '0' which can cause errors detection.
A fourth differential pair, called the TMDS clock provides the pixel clock to the time the data stream. The maximum TMDS single link pixel clock frequency is 165 MHz.
What is the data rate of a single link HDMI connection: The maximum pixel clock speed is 165MHz and each of the 3 TMDS video streams comprises 10 bits. Therefore, the overall data rate is 3 x 10 x 165MHz = 4.96Gbps.
How pins are included in the HDMI connector: There are 19 individual points in the HDMI connector. There are 3 pairs of TMDS signals which carry all the audio digital video signals.
How is the digital audio signal transported: The multi-channel audio in the time multiplexed flows TMDS data. Audio is much lower speed (192kbps) and overtime is used to demultiplex the audio signals.
What is HDCP HDCP stands for High-Bandwidth Digital Content Protection. HDCP is an encryption method developed by Intel in order to control unauthorized copying digital media. Encryption takes place in the HDMI transmitter in the "source" (DVD drive, decoder) and decryption is done by the receiver HDMI (HDTV display). The secret keys for encryption are exchanged between the source and display over an I2C bus (pins 15 and 16).
HDMI is compatible with DVI: DVI is the predecessor of HDMI. HDMI and DVI are identical as regards the video. Therefore, there is a compatibility video. However, DVI will not support digital audio. For example, if you have a DVI connection the largest source and an HDMI connector on the screen, a DVI to HDMI cable is all that is required to view video. A separate audio cable (TOSLINK or SPDIF) will be required to carry audio Digital.
What support both HDMI: HDMI is the broadband connection and support resolutions of 480i, 480p, 720i, 720p, 1080i and in the future, 1080p.
Conclusion:
HD technology is evolving rapidly. HD connections such as HDMI will become the standard facto connections to high definition. We have presented the key features HDMI, so that consumers are well informed and ready to make intelligent purchasing decisions.
