Gesture based control of objects displayed on touch screen displays is described. An object is displayed on a touch screen display, and a first touch operation is detected at a first position on the display. The first position is within an area that is associated with the displayed object. A second touch operation is detected within the area. After detecting the first and second touch operations another, a third touch operation is detected at a third position. A distance between the third position and the first position is calculated. When the distance is greater than a predetermined value, a copy of the object is displayed on the touch screen display.

Gesture-based object manipulation methods and devices

A method of operating an electronic device may include providing first graphic output of a first application on a display.

Where a restricted channel links a subscriber location and an access node of a digital video network, a bandwidth allocation server may receive a bandwidth reservation request to reserve bandwidth on the restricted channel that includes a reservation start time. The bandwidth allocation server can obtain any existing bandwidth reservations for bandwidth on the restricted channel at least partly covered by the duration of the reservation request (the duration being delimited by the reservation start time), and determine whether a bandwidth limit is exceeded by a combination of the bandwidth reservation request and any existing bandwidth reservations, at any time covered by the bandwidth reservation request. When it is determined that the combination is under the bandwidth limit, a reservation accept response can be sent and a reservation can be stored. Otherwise, a reservation reject response can be sent.

Method for temporal admission control in a digital video network

Methods, electronic terminals, and systems are disclosed for controlling the display of video streams on an electronic terminal. A plurality of the video streams are received at the electronic terminal from the media server. The received video streams are displayed in an ordered set of elements on a display device of the electronic terminal. A user selection of at least a first one of the elements is received. Commands are communicated, responsive to the user selection, from the electronic terminal to the media server to control the quality of service of the video streams that are displayed in each of the non-selected elements in response to their respective location within the ordered set of elements relative to the selected first element.
