The dvd player RCT699H from LG is connected to the TV via HDMI or scart. With HDMI, you have better image and sound quality compared to scart. The device can record DVD discs. Through the built-in USB media player, you can connect an external hard drive or USB stick and watch the content you have already saved. The device has an analog output for sound as well as digital outputs digital audio coaxial and optical. The optical output transfers the audio signal through an optical fiber cable, resulting in no interference and the best possible sound quality, while the coaxial output resembles the analog RCA but differs in resistance and the fact that it requires only one cable for the transmission of the audio signal. The set of connections is completed by the analog output composite video (or CVBS). The composite video connection transfers, through a cable, an analog video signal only, with standard definition image quality.
