Abstract

The present invention discloses a digital broadcast receiver and broadcast data display method enabling simultaneous display of multi-channel visual images. The broadcast data display method includes receiving digital broadcast data on a plurality of channels; simultaneously outputting on a single screen real-time broadcast data of a selected channel and still images of the remaining channels; and periodically updating the still images of the remaining channels. Thereby, up-to-date multi-channel visual images are simultaneously output. Hence, the user can easily perform channel selection and channel switching.

Description

technical field [0001] The present invention generally relates to a digital broadcast receiver, and more particularly to a digital broadcast receiver and a broadcast data display method in which multi-channel visual images are simultaneously displayed to support easy channel selection and switching. Background technique [0002] In digital multimedia broadcasting (DMB), various multimedia signals including audio and video are digitally modulated and provided to users. Specifically, a user in motion can receive various multimedia programs through a portable personal receiver or a vehicle-mounted receiver equipped with a unidirectional receiving antenna. [0003] Advances in memories capable of storing large amounts of digital multimedia data such as moving pictures and music videos and popularization of mobile communication terminals have supported the recent development of mobile communication terminals with DMB reception capabilities such as DMB phones and commercialize. ...
