What is the HDMI® converter?
The
High -resolution multimedia interface (HDMI®) is a digital audio interface that also carries multi -channel or spatial sound digital sound signals. HDMI® improves previous analog technologies and requires only one 19 HDMI® cable to carry audio and video. The HDMI® converter is a separate Middleman device that digitally processes HDMI® analog signals.
For example, many older DVD players have analog components outputs (YPBPR) to connect to a standard TV (SDTV) or high -resolution TV (HDTV). Video components separate the video signal into Chroma and Luma signals that carry separate data flows of color and synchronization. Component ports of RCA on commercial products are color -marked with red, green and blue, as well as a designated video cable components. Video components require a separate audio cable that can either be available multi -channel digital sound, or stereo RCA analog sound.
As HDTVS HAVE overtakes SDTV, many people prefer to use their HDTV HDMI® connection over alternative and lower analog connections. In the above example, the HDMI® converter would sit between a DVD player and HDTV, which receives an outgoing component and audio cables from DVD. The HDMI® converter internally converts signals to HDMI® digital format and processes stereo sound into a multi -channel digital sound (if necessary) and emits these streams on the HDMI® port on the converter. The HDMI® cable then runs from the converter to the HDMI® input port on HDTV.
There are several different types of HDMI® converters that can handle different scenarios and connections. HDMI® converter made for S-Video and Composite video signals can UPSCale standard 720p high resolution video resolution. The original aspect ratio may be announced, in this case 4: 3 verses a high -resolution aspect ratio of 16: 9. Following 4: 3 UPSCALED signals in 16: 9 tracks is possible using manual sides to HDTV, but the image will be unnaturally stretched in some way to fill the screen because the original signal simply does not have data for a larger image extrapolation.
The digital video interface (DVI) used on current computer monitors is already compatible with HDMI®, but does not carry sound. The HDMI® converter can be used to combine DVI and outgoing digital or analog audio signals for HDMI® output.
In some cases, you may require reverse settings if you want to release the HDMI® signal to an analog device that has only analog inputs. This HDMI® converter flavor is also available and reverses processing HDMI® to the relevant analog signals for outgoing analog wiring. This converter includes a downscaler where the converter receives 480i to 1080i inputs and output 480i (NTSC) or 576i (PAL) SDTV for these devices that only supportStandard resolution.
HDMI® Converters are available online and for many local retailers who sell HDTV and home entertainment equipment. The technology used for UPSCALE or Downscale signals can significantly change the image quality, so it pays to read customer reviews to see which products have a high satisfaction rating.
