  • Patent number: 11443680
    Abstract: The present invention provides a dithering and directional modulation-based frame rate conversion apparatus comprising: a directional delta modulation generator configured to receive a plurality of input color data representing a plurality of input color components of an input pixel color and generate a plurality of modulated data for the plurality of input color data respectively; and a plurality of dithering modules configured to perform K-bit dithering conversion on the plurality of input color data respectively to generate a plurality of output color data for representing a plurality of output color components of an output pixel color with a color depth of K bits per component, where K is an integer equal to or great than 1. The present invention can allow display to support frame rates higher than its standard configuration without observable color depth degradation.

  • Patent number: 10097608
    Abstract: Technologies for wireless transmission of digital media include a wireless retransmission hub configured to receive an input digital media stream from a source computing device. The wireless retransmission hub is further configured to transmit a list of available destination computing devices to the source computing device, receive a list of selected destination computing devices from the source computing device, and map each destination computing devices of the list of selected destination computing devices to the source computing device. The wireless retransmission hub is further configured to transmit an output digital media stream to each of the selected destination computing devices of the list of selected destination computing devices, wherein the output digital media stream includes the digital media of the input digital media stream. Other embodiments are described and claimed herein.

  • Patent number: 9390717
    Abstract: The present technology relates to an encoding device and method, a decoding device and method, and a program that enable audio of a high audio quality to be obtained with a smaller code amount. The encoding device multiplexes low frequency encoding data obtained by encoding a low frequency component of an input signal and high frequency encoding data obtained by encoding data including an estimation coefficient to acquire a high frequency component of the input signal by estimation and outputs multiplexed data. When the input signal is encoded, a calculation unit calculates pseudo high frequency subband power to be an estimation value of power of the high frequency component from an estimation coefficient selected in a frame immediately before a frame of a processing target and the high frequency component of the input signal.

  • Patent number: 8885703
    Abstract: A video transmission system includes a transceiver module that transmits a video signal to a remote device over at least one communications channel wherein the video signal is transmitted as at least one separate video layer stream chosen from, an independent video layer stream and at least one dependent video layer streams that require the independent video layer for decoding. A control module determines at least one channel characteristic of the at least one channel and chooses the at least one separate video layer stream based on the at least one channel characteristic of the at least one channel.
