Description

Method and device for providing a screen composed of multiple tiles The present invention relates to a method and apparatus for providing a screen composed of a plurality of tiles. Specifically, it relates to a method and system for easily providing a screen composed of tiles of different resolutions. Recently, the penetration rate of various media content and IPTV has increased. As a result, it has become commonplace in daily life for users to select and watch the content they want from among various broadcast options. Information regarding the viewing methods of broadcast content can be confirmed through the Korea Communications Commission’s “2022 Survey on Broadcast Media Usage Patterns.” According to the survey, 91.1% of domestic broadcast content viewers watch live channels. Additionally, 88.5% of users utilize TV receivers to watch live channels. Many users watch live channels via TV receivers, and the variety of channels provided by pay-TV operators is diverse, averaging around 250 channels. As the variety of available channels increases, users are experiencing inconvenience due to the increased time spent searching to select their desired channel or program.
