摘要： Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.

摘要： Complexity for a video frame after a special event is estimated and used for encoding the frame. The complexity for a key frame of a special event is estimated based on its intra activity and a complexity of a previously encoded key frame in the video stream prior to the special event. The complexity for a dependent frame after a special event is estimated based on a motion estimation cost for the dependent frame and a complexity of a previously encoded dependent frame prior to the special event.
