PURPLELEC video converter device is a hardware device that allows users to convert video from one format to another. These devices can be used to convert video formats, such as HDMI, SDI, AHD tapes, to more modern digital formats, such as simulating signal or extended video signal.
Another example is a HDMI to RCA converter, which convert digital HDMI signal to the RCA signal. This allows devices with HDMI output, such as a computer or a DVD player, to be connected to a TV or monitor that has RCA inputs. This can be useful when the TV or monitor does not have an HDMI input or if the HDMI input is occupied by another device.
