  • Patent number: 11900953
    Abstract: An audio processing method includes the following operations. A calculated value is obtained according to multiple audio clock frequency information contained in multiple audio input packets. An audio sampling frequency is generated according to the calculated value and a link symbol clock signal. Multiple audio output packets corresponding to the audio input packets are generated according to the audio sampling frequency.

  • Patent number: 11841740
    Abstract: The present invention provides a DP-out adapter including a decoder, a clock signal generating circuit, a DP signal generating circuit and a symbol counter value comparator. The decoder is configured to decode a USB signal to generate a plurality of packets. The clock signal generating circuit is configured to generate a clock signal. The DP signal generating circuit is configured to generate a DP signal according to the packets, and output the DP signal according to the clock signal. The symbol counter value comparator is configured to generate a first counter value according to a number of symbols corresponding to the plurality of packets, and use the clock signal to count to obtain a second counter value, and compare the first counter value and the second counter value to generate a control signal to the clock signal generating circuit to adjust a frequency of the clock signal.

  • Patent number: 8559745
    Abstract: An image signal processor for image enhancement is provided. The image signal processor receives a first, a second, and a third component of an RGB signal of each pixel of an image, and has: an image enhancer for performing image enhancement on the first component of the RGB signal to produce a first enhanced component of the RGB signal; a gain generator, coupled to the image enhancer, for producing an enhancement gain based on the first component and the first enhanced component of the RGB signal; and a gain multiplier, coupled to the gain generator, for performing image enhancement on the second and the third component based on the enhancement gain to produce a second and a third enhanced component.
