    摘要： Methods for removing redundancies in a video stream based on efficient pre-transmission detection of static portions of the video stream. In one embodiment supporting wireless transmission of a video stream having a series of video frames, a mathematical operation (such as a hash function, summing operation or CRC) is performed on (1) a (reconstructed) data block(s) of a video frame in order to generate a first check value and (2) a co-located data block(s) of a second, sequential video frame in order to generate a second check value. The first and second check values are compared to detect static video content in the video stream. When static video content in a video stream is detected, the static nature of the content is indicated in the compressed bit stream and the amount of wirelessly transmitted data corresponding to the static portions of the video stream may be reduced.

    摘要： An integrated multi-mode radio transmitter includes a multiplexor and a shared front-end. The is operable to select an IF signal of a plurality of IF signals based upon a selection signal that is indicative of a particular operational mode of the one of the plurality of IF signals. The shared front-end is coupled to receive the selected IF signal, wherein the shared front-end converts the selected IF signal into a radio frequency (RF) signal that is modulated in accordance with the particular operational mode of the one of the plurality of IF stages.

    摘要： A portable computing device includes a three-dimensional (3D) touch screen and a core module. The 3D touch screen includes a two-dimensional (2D) touch screen section and a plurality of radio frequency (RF) radar modules. The core module is operable to determine whether the 3D touch screen is in a 3D mode or a 2D mode. When the 3D touch screen is in the 3D mode, the core module is further operable to receive one or more radar signals via one or more of the plurality of RF radar modules and interpret the one or more radar signals to produce a 3D input signal.
