Abstract: The present disclosure discloses a method, apparatus, and system for sharing a virtual reality (VR) viewport. The method may include: establishing, by a content distribution server, a first transport connection; receiving, by the viewport sharing server, panoramic video data; establishing, by the viewport sharing server, a second transport connection for receiving first viewport information supplied by the terminal or transmitting second viewport information to the terminal; rendering, by the viewport sharing server, the received viewport information; receiving, by the terminal, the panoramic video data; converting, by the terminal, the panoramic video data into first video data; rendering, by the terminal, a first video within the user viewport scope; receiving, by the terminal, the second viewport information; converting, by the terminal, the panoramic video data into second video data corresponding to the second viewport information; and rendering, by the terminal, a second video corresponding to the second viewport information.

Abstract: Provided is a method of operating an image display apparatus, the method including receiving a channel packet corresponding to a virtual channel from an external apparatus via a network and storing the received channel packet; obtaining channel attribute information of the virtual channel from the channel packet; and adding the virtual channel to a channel list including a normal channel by using the channel attribute information. The image display apparatus may increase the efficiency of accessing a virtual channel service, by adding and managing a virtual channel without necessitating major interventions of a user.
