  • Patent number: 8341494
    Abstract: A decoding apparatus for a high-density recording medium includes a demodulator, a long-distance code (LDC) processing module, a burst indicator subcode (BIS) processing module, an erasure code generator, and a decoder. The demodulator demodulates data from a high-density recording medium to obtain a demodulated data and a demodulation error flag. The LDC processing module and the BIS processing module deinterleave the demodulated data to respectively obtain an LDC data and a BIS data. The erasure code generator sets an erasure flag corresponding to the LDC data according to the demodulation error flag and the BIS error flag. The decoder decodes the LDC data according to the erasure flag. Further, the decoder decodes the BIS data to obtain the BIS error flag.

  • Patent number: 7437674
    Abstract: A video processing method. A display region is provided according to a timeline, comprising at least one first sub-region with higher time resolution and one second sub-region with lower time resolution. A time scale value of the first sub-region is smaller than that of the second sub-region, and the first and second sub-regions have low-speed and medium-speed controls for scrolling forward and backward respectively. When a desired frame is located in the first sub-region, the low-speed or medium-speed control is scrolled to forward or backward on the timeline according to an operating command to locate the desired frame. When the desired frame is located in the second sub-region, the low-speed or medium-speed control is scrolled to forward or backward on the timeline according to an operating command to move the desired frame to the first sub-region.
