  • Method and device for detecting preamble of wireless data frame
    Patent number: 7218628
    Abstract: A method and a device for detecting a preamble type of a wireless data frame are provided. The preamble has a synchronization (SYNC) field and a start frame delimiter (SFD) field, and the method comprises following steps. The wireless data frame is first received, and then determined whether the wireless data frame has a short preamble. When the wireless data frame has the short preamble, the wireless data frame is transmitted to a MAC device. In addition, if the wireless data frame does not have the short preamble, it determines whether the wireless data frame has a long preamble. When the wireless data frame has the long preamble, the wireless data frame is then transmitted to the MAC device.

  • Low-complexity spatial downscaling video transcoder and method thereof
    Patent number: 7180944
    Abstract: A low-complexity spatial downscaling video transcoder and method thereof are disclosed. The transcoder comprises a decoder having a reduced DCT-MC unit, a DCT-domain downscaling unit, and an encoder. The decoder performs the DCT-MC operation at a reduced-resolution for P-/B-frames in an MPEG coded bit-stream. The DCT-domain downscaling unit is used for spatial downscaling in the DCT-domain. After the downscaling and the motion vectors re-sampling, the encoder determines the encoding modes and outputs the encoded bit-stream. Compared with the original CDDT, this invention can achieve significant computation reduction and speeds up the transcoder without any quality degradation.
