  • Patent number: 11435597
    Abstract: A displaying device adapted to a screen is provided. The displaying device includes a transparent pyramid, a movable support, and an image conversion unit. The movable support is connected to the transparent pyramid to move the transparent pyramid between a first location and a second location which is different from the first location. The first location is the position on the screen. The image conversion unit is configured to receive image data. When the transparent pyramid moves to the first location, the image conversion unit converts the image data to a holographic image displayed on the screen, and the transparent pyramid generates a 3D hologram based on the holographic image.

  • Patent number: 7630647
    Abstract: A hybrid IR transmission system implements at least two IR transmission protocols with a common IR transceiver. The hybrid IR transmission system includes an IR decoding circuit, a common IR transceiver and a filter circuit. The IR decoding circuit includes an IrDA module for decoding IR signals in IrDA protocol and a CIR module for decoding IR signals in CIR protocol. The common IR transceiver receives a first IR signal in either IrDA or CIR protocol. The filter circuit processes the first IR signal into a second IR signal accessible to one of the IrDA module and the CIR module for decoding.

  • Patent number: 7243073
    Abstract: A method for realizing virtual multi-channel by spectrum analysis is disclosed. The low-frequency-effect sound data is obtained by averaging sound data of left and right channels in the two-channel sound source and filtering the average by a first low pass filter. The central channel sound data is obtained by averaging sound data of the left and the right channels in the two-channel sound source and filtering the average by a second low pass filter. The surround right and left sound data is obtained by copying sound data of the left and the right channels in the two-channel sound source, respectively.

  • Publication number: 20070036228
    Abstract: An audio encoder for coding an audio bitstream. The side flag is asserted when a first side information and a second side information are the same, a scale flag is asserted when a first scale factor and a second scale factor are the same. A data packer packs a set of variable-length codes into a main data field of the frame, and packs the side flag and the scale flag into an ancillary data field of the frame. The second side information is packed into a side information field of the frame if the side flag of the frame is not asserted, and the second scale factor is packed into the main data field of the frame if the scale flag of the frame is not asserted. An audio decoder is also provided for decoding the encoded audio bitstream generated from the audio encoder.
