Due to the development of MPEG (Moving Picture Experts Group) technology, which is a compression standard for moving image data to compress digital image data that requires a relatively large amount of data, the size of digital image data is gradually getting smaller. Increasingly, digital video and audio services have been applied to almost all fields such as communication and telecommunications, and digital devices for providing such services have emerged.

Among them, broadcast television receivers (TV) occupy an important place as an easy and effective information transmission medium in daily life, and recently, with the development of science and technology, various kinds of TVs, for example, interactive TVs and wall-mounted TVs, have been developed. .
