DVI vs. HDMI, what is the difference? Which is better? DVI and HDMI are compatible? And of course, given the choice, you must use that? The differences (or lack there of) will surprise you. Let's look at each one of them then to evaluate the differences.
Digital Visual Interface (DVI) is a digital standard in 1999 by the Digital Display Working Group (DDWG) was introduced. It 'was designed primarily for carrying uncompressed digital video data to a display. OriginallyThe display is a computer monitor, but DVI is now commonly used for television as well. One of the main areas of confusion with DVI is the number of different connections available, representing various functions. There are three connections for DVI, DVI-D (digital only) DVI-A (analog) and DVI-I (digital and analog).
Hdmi
High-Definition Multimedia Interface (HDMI), was released in late 2002, is an all-digital audio / video, streaming videoFlows similar to DVI. However, HDMI also offers the ability to transmit audio signals, as well as videos, and inclusion of HDCP, which is a digital rights management technology.
So what's the difference?
If we consider the differences between HDMI and DVI, we find that they actually have more in common then differences. Both digital transmission, are derived in a similar specifications as the HDMI from the DVI specification. There aretwo important differences:
HDMI includes content protection called High Definition Content Protection (HDCP).
HDMI supports audio in addition to digital video. (DVI only supports digital video)
DVI and HDMI are compatible?
HDMI is compatible with DVI? Since DVI is the predecessor of HDMI and DVI are the same as the video is. Therefore, there is video compatibility. However, DVI does not support digital audio. For example, if you have an older DVIConnecting to the source and an HDMI port on the display, a HDMI to DVI cable all that is required to view the video. A separate audio cable (TOSLINK or SPDIF) will be required to contribute to digital audio.
A notice of cable length
The HDMI specification does not define the maximum length of cable. HDMI 1.3 defines two types of cables: Category 1 (standard or HDTV) and Category 2 (High-Speed or greater than HDTV) independently, to work either via HDMI or DVIDistances of over 15 meters. If you need a cable longer than 10 meters, you will definitely want high quality of the cable is taken into account. For all that have greater than 15 feet, some companies amplifiers, equalizers and repeaters that can help bridge longer distances.
What should I use today?
If available, we recommend HDMI. This is not because it is better then DVI, only because the industry accelerates due to the strong HDMI HDCP digital rights management technology. ButYou should not expect any difference when switching from DVI to HDMI, so if you're already over DVI, stay with him until the next standard comes around. A bit 'off topic, but still important, is that you will be able to offer a video quality similar to getting the components of the existing connections. A common misconception is that the component can not bring HDTV-quality video that is wrong. Depending on the components of the system you can use the same or better performance obtained with a componentThen connect with an HDMI or DVI.
