  • Publication number: 20090190038
    Abstract: A method for detecting a non-rigid-body in video coding and an integrated circuited for the same are disclosed. The integrated circuit capable of detecting non-rigid-body comprises a best matched block, a correlation unit, and a non-rigid-body detection unit. The best matched block unit receives a current block in a current video frame and block searching a reference video frame to determine an initial motion vector for a best matched block in the reference video frame. The correlation unit, coupled to the best matched block unit, receives the best matched block, and computes a correlation between a corresponding block and the best matched block. The non-rigid-body detection unit, coupled to the correlation unit, determines whether the current block contains non-rigid-body according to the correlation.

  • Publication number: 20090190037
    Abstract: An integrated circuit capable of video processing and a method thereof is disclosed. The integrated circuit comprises an image information generator, an adaptive motion vector (MV) candidate generator, and a block matching unit. The image information generator receives reference and current video data to determine image information. The adaptive MV candidate generator, coupled to the image information generator, receives the reference and current video data to generate spatial and temporal MV candidates, and generates an updated MV candidate based on the image information. The block matching unit, coupled to the adaptive MV candidate generator, receives the spatial and temporal MV candidates and the updated MV candidate and performs block matching to determine an output MV therefrom.

  • Publication number: 20080178109
    Abstract: This specification discloses a virtual dynamic pattern system that changes its display status according to the external information. A host is built in with a virtual dynamic pattern rendering procedure. The host controls a display to show a dynamic pattern. The rendering procedure sets the internal/external parameters of an initial pattern, corresponding to the internal/external features of the pattern. The host obtains the external parameters using an external information extracting unit for changing the features. In addition to allowing the user to change the internal dynamic parameters via the input device of the host for changing the dynamic pattern display images, the host further automatically obtains external information and changes the external dynamic parameters. The dynamic pattern thus changes according to the external information, rendering the variety of images.

  • Publication number: 20030219075
    Abstract: A method and apparatus of signal compression using adaptive pulse code modulation (ADPCM) with variable width frame is provided. The present invention enables a low distortion rate in the process of the ADPCM signal compression by installing a frame width modifier on the input of a code analyzer and corrector which repetitively receives compressed data and generates reference values to attain an optimal delta value for a given resolution condition that enables high compression ratio and data integrity in the data compression and decompression processes.

  • Patent number: 5499147
    Abstract: A method and tape recorder apparatus are disclosed for recording a signal on a tape. The tape recorder apparatus is provided with a memory for storing a signal to be recorded on a tape. The tape recorder apparatus has a recording head for recording the signal stored in the memory. The tape recorder apparatus also has a playback head for reproducing the signal recorded by the recording head on the tape. Furthermore, the tape recorder apparatus has a comparison circuit for comparing the signal reproduced by the playback head with the signal stored in the memory. Depending on errors identified by the comparison circuit in the reproduced signal, the signal in the memory is re-recorded on the tape.
