Abstract: A back cover module adapted to be disposed on a casing having a back opening is provided. The back cover module includes a fixing bracket, a sliding bracket and a rotating mask. The sliding bracket is slidably disposed on the fixing bracket along a first direction. The rotating mask is pivoted to the sliding bracket. When the fixing bracket is fixed to a position of the casing adjacent to the back opening, the fixing bracket and the sliding bracket are adapted to be inside the casing and a portion of the rotating mask is exposed from the casing. The rotating mask is adapted to follow the sliding bracket and move relative to the fixing bracket toward the first direction to a position out of the casing, and is adopted to rotate relative to the sliding bracket and shield the back opening after being moved out of the casing.

Abstract: A system and a method are disclosed for displaying menu options. A menu icon is displayed on a touch-sensitive screen. In some embodiments, the menu icon is displayed with a feed from a social networking system. In response to detecting a contact with the menu icon, an animation of a plurality of sub-menu icons emanating from the menu icon is displayed. The sub-menu icons move along different predefined paths to different predefined positions. Each sub-menu icon is associated with an interface to post content to a social networking system. In response to detecting a contact with a sub-menu icon, the interface associated with the sub-menu icon is displayed.

Abstract: A method is provided in one example and includes receiving a request for a video session and establishing the video session between a first user and a second user. The method further includes communicating a first stream of packets associated with signaling data that propagates to a first network, which provides a first network connection to the first user. The method also includes communicating a second stream of packets associated with media data that propagates to a second network, which provides a second network connection to the second user. The media data can include audio data and video data.
