摘要： A video signal processing device includes first access circuitry for writing a video signal in a memory capable of storing a video signal of at least two picture frames, and second access circuitry for reading the video signal from the memory. Comparision circuitry then compares a first address accessed by the first access circuitry with a second address accessed by the second access circuitry. The second address is then shifted by the amount of an integer of picture frames in accordance with the result of the comparison either at the moment when the first access circuitry is granted access to the memory or when access of the first access circuitry to the memory is stopped.

摘要： When a moving picture is encoded with a high compression ratio by the MPEG, the block noise becomes remarkable. Matching is calculated between the first and the second key frame and corresponding point information is generated. According to this corresponding point information, a virtual second key frame is generated. A difference between the actual second key frame and the virtual second key frame is compressed/encoded by a difference encoder. The first key frame, the corresponding point information, and the compressed/encoded difference are outputted as encoded data between the first and second key frame.

摘要： A signal processing device including a central processing block and plural signal processing function blocks, which are mutually connected by a common address bus and a common data bus, wherein analog signal lines are provided for analog signal transmission between the central processing block and the plural signal processing function blocks and the central processing block is provided with a D/A converter and an A/D converter connected to the analog signal lines. Thus there are only required a D/A converter and an A/D converter in the central processing block, for analog signal transmission between the central processing block and each of the processing function blocks. Also the wiring can be simplified as the number of analog signal lines is limited.

摘要： A digital signal to be recorded is converted into a digital signal having a suppressed low-frequency spectrum and having a shortest recording wavelength greater than half an original shortest recording wavelength, and the converted digital signal is recorded on a magnetic recording medium in which a plurality of metal evaporated films having different crystal-growth directions are laminated. The digital signal is reproduced from the magnetic recording medium in which the plurality of metal evaporated films having different crystal-growth directions are laminated. Waveform equalization is performed on the reproduced digital signal, and integration detection is performed on the waveform-equalized digital signal, thereby restoring an original digital signal.
