  • Patent number: 9204086
    Abstract: A method and apparatus of frame rate conversion where descriptive information relating to an input video signal is transmitted to the frame rate converter along with the input signal. The descriptive information is used to interpolate frames, allowing the interpolator to make pixel analysis using the descriptive information relating to the original signal. The descriptive information is derived by a compositor/scaler and is transmitted to the frame rate converter with the composited/scaled signal. There may be multiple input signals that are composited to make a final composited video output such as a picture-in-picture display. The information may be transmitted in-band with the video signal received by the frame rate converter. Alternatively, the descriptive information may be transmitted in a separate stream in a side-band manner. In another embodiment, the descriptive information may be transmitted to the frame rate converter separate from the video input source as commands or packets.

  • Patent number: 9202590
    Abstract: A clock control circuit for a parallel in, serial out (PISO) shift register helps save power. The clock control circuit selectively clocks the shift register as it converts a parallel input to a serial output. For example, the clock control circuit may provide clock signals to the flip flops (or other buffers) in the shift register that will receive data elements provided with the parallel input. However, the clock control circuit withholds clock signals from flip flops that will not receive data elements provided with the parallel input, or that have already been received by a particular flip flop. As the parallel loaded input elements propagate serially through the shift register, on each clock cycle an additional memory no longer needs to be clocked. The memory no longer needs to be clocked because that memory has already propagated its loaded input element to the following memory, and no further element provided in the N element parallel loaded data is incoming.

  • Publication number: 20150341106
    Abstract: A relay receives a frame from a source, and based on state of a relayed frame bit within the frame, the relay selects an operational mode: implicit acknowledgement mode, first explicit acknowledgement mode, or second explicit acknowledgement mode. The relay sets the relayed frame bit in subsequent transmissions to indicate transmission opportunity (TXOP) control of the communication medium (e.g., whether under control of the relay or the source). The source may receive acknowledgement of the relay's successful receipt of the frame implicitly via the relay transmitting a relayed frame to the destination. Alternatively, the source may receive acknowledgement of the relay's successful receipt of the frame explicitly in a response frame from the relay. State of a more data bit in the frame receive from the source may indicate the source has one or more additional frames intended for the destination.
