About HDMI to Scart
As a means of transmitting audio and video signals, the SCART standard has been around for many years, and it was designed to carry analogue signals. With more and more modern devices using the digital-based HDMI format, it isn't possible to simply use a cable when trying to convert one signal to the other (such as a rudimentary HDMI to SCART lead) - converting between the two formats requires a dedicated device. Such devices are designed to carry out the process with as little loss in quality as possible.
When looking at products in this area, it is important to note whether they are 'SCART to HDMI' or 'HDMI to SCART' - each type of conversion requires a unique set of components. If a device is only capable of outputting audio and video through SCART, one of these devices allows the user to not only view the picture, but to also upscale the image to various standards of HD video (such as 720 or 1080 lines). Other elements of HDMI, such as the ability to handle 3D signals, are also integrated into some of these convertor boxes.
With any kind of process that involves connecting together various standards of audio and video cables, there will sometimes be a need for some additional cabling, such as situations where the user has a SCART to HDMI convertor with no SCART output on the original device. If other formats are available, such as composite, component or S-Video, leads can be obtained that carry out this stage of the connection before it reaches the SCART connector.
