![]() But as mentioned above, this case is pretty rare today since standards are being upgraded consistently. There might be connection problems with HDMI that lead to an outage of audio and visuals. Because if the existing connection doesn’t fit CP, the DVD you just bought won’t show an image and the show in HDTV won’t either. Whereas not every DVI connection is suitable for copy protection, so you will definitely have to check the descriptions. When we look at audio quality, HDMI is able to play stereo sound and home cinema atmosphere while DVI will entail the need for an additional cable to transmit audio signals.Īlso when using HDMI, anything displayed is subject to copy protection HDCP. Expanding its lead with the ability to carry uncompressed video as well as uncompressed audio. HDMI however might still be the unique connection among several options. The information regarding connection difficulties and wear can seem like a negative point at first, but the quality of the connectors itself, just like the overall quality standards, are consistently adapted and upgraded though. When comparing DVI and HDMI we can quickly see pro’s and con’s, as well as some qualitative differences regarding their application. Since there are graphics cards that have a built-in HDMI output, a sort of HDMI adapter. So if you happen to already use a DVI cable, you will be able to transmit signals via DVI-D or DVI-I to an HDMI input.Įven though HDMI is used mostly in entertainment electronics, you may also find it in the IT sector. Meaning that such signals as digital signals (DVI-D) or analog and digital signals (DVI-I), can be converted to HDMI with the help of an adapter. DVI on the other hand, is upward compatible in most cases. HDMI is backward compatible with DVI, meaning not all HDMI signals can be converted to DVI, not even with adaptors. HDMI is an advancement on DVI, mostly used in consumer electronics and responsible for digitally transferring video and audio data. Which leads us to our next topic: digital transfer via HDMI What is HDMI? Mostly because the expectations in this industry are much higher and continue to grow. Even though there are TVs with a DVI input that can convert signals from digital sources, like a DVD player or a computer, there are different standards in consumer electronics. This receiver again, decodes the data back to a parallel data flow.ĭVI is mainly used in the IT sector as the electronic interface for computers and as a standard for video transmission. Here they are encoded into serial digital data. After that, the data is transferred via cable in a serial data transfer to the monitor, which is equipped with a TMDS receiver. The Digital Visual Interface (DVI) replaces the VGA connection (Video Graphics Array) between the modern monitor and the graphics card.ĭuring the digital DVI transmission, digital color data from the graphics chip gets passed on to a TMDS transmitter in a parallel data flow of 24-bit. So why is there no standard for getting the data from one to the other to prevent any loss of quality?Īnd this is where DVI comes in. To sum it up: the display needs digital data, the graphic card provides digital data. Without the need for converting analog signals first. With the rapid changes to flat screen TVs (LCD or flat panels) the demand for a much more direct way of transferring digital data is growing. Sounds complicated? It is! And a lot of quality gets lost this way. Initially even the modern TFT Displays (flat screen monitors) receive their data this way just to then convert the analog signals back to digital data via an analog to digital converter. Since classic analog monitors of course need analog signals to display anything. ![]() Let’s go back to the beginning of the DVI interface, the first to enable optimal quality in digital transfer between graphic card and modern flat screen displays, moving us away from the analog connection.īecause originally a digital to analog converter (which is built into the graphic card these days) converts the digital data from the graphic card to analog data, so it can be transferred to the monitor from an analog connection (VGA). ![]() Read more, to find out which cable connection is best for your Digital Signage display. But what is changing in the transfer of video and audio data between players and playback devices and in the requirements for the connector?įrom analog scart connections to digital HDMI transmission, we will show you what you need to know. And it brings with it incredible changes to the AV interface, that make the audio- and video world that much more versatile and sharp. It’s nothing new, that especially in the entertainment industry digitalization shows what it’s got. Many things have changed in the past few years – at breakneck speed! Technology is evolving rapidly – and unstoppable – and with it comes the age of digitalization, playing a major part in all areas of the industry.
