IPC: H04N1/40
Filed: 1989-11-10
Abstract: PURPOSE:To prevent a blur of an estimate picture by preparing plural kinds of scanning apertures and selecting an optimum scanning aperture to apply estimate of intermediate tone.

While the fault of a function circuit 1 or 2 is decided when the output of the circuit 11 is equal to '0'. In such a case, the following two outputs 42 and 43 are set at '0' and the controller 12 checks the output of the circuit 11. Then the fault of the circuit 1 is decided when the output of the circuit 11 is equal to '1'. While the fault of the circuit 2 is decided when the output of the circuit 11 is equal to '0' respectively. As a result, the controller 12 can monitor the faults of the function circuits per bit and at the same time can detect the faulty function circuits just by changing the output code of the circuit 7.

Title: Data compressing and encoding method
Inventor: SUZUOKI MASAKAZU
IPC: G10H7/02
Filed: 1988-11-19
Abstract: PURPOSE:To eliminate a fine difference in frequency at the time of waveform reproduction and to reduce errors caused by the block switching of block-by- block bit compression processing by setting the number of words corresponding to (n) cycles of waveform data to an integral multiple of the number of words in a compressed code block. CONSTITUTION:When the waveform data with a constant period TW are compressed code in block units of each word of (h) samples and then stored in a memory, the number of words corresponding to (n) cycles of waveform data with the constant period TW is set to (m) times as large as the number of words in the compressed code block (h, n, m: natural number). Thus, the number of words corresponding to the waveform data in a looping section LP is set to an integral multiple of the number of words in the compressed code block, and then the border between a looping point and the compressed code block is coincident. Consequently, errors due to the block switching of bit compression are reduced and the fine difference in frequency among different kinds of reproduced waveforms is eliminated.
