IPC: H04N9/84
Filed: 1986-03-27
Abstract: PURPOSE:To obtain a low-frequency conversion chrominance signal with high accuracy by adding/subtracting an output from a latch circuit synchronously with a clock pulse synchronized with a set integral number and a chrominance subcarrier and generating a low-frequency conversion chrominance subcarrier wave based on the output. CONSTITUTION:An integral number N1 set in digital value and a digital value outputted from a latch circuit 13 synchronously with a clock pulse synchronized with the chrominance subcarrier wave are added (11) and the added output is held in the circuit 13 synchronously with the clock pulse. When an added output N3 reaches a prescribed value N2 or over, a value of 2N2-N3 is held in the circuit 13 synchronously with the clock, the integral number Nl is subtracted (12) by an output from the circuit 13 successively. the subtraction output is held in the circuit 13 and when the subtraction output N4 reaches 0 or below, a value 0-N4 is held in the circuit 13, the output of the circuit 13 and the integral number Nl are added (11) and held in the circuit 13, then the operation above is repeated. Then the output of the circuit 13 is subjected to D/A conversion 17 and the low-frequency conversion chrominance subcarrier wave having a frequency of Nl/2N2 of the clock pulse is generated from a LPF 18.

IPC: H04N19/91
Filed: 1989-03-22
Abstract: PURPOSE:To easily attain the efficient coding of picture information by setting automatically proper coding mode in response to the activity of an input picture or information quantity. CONSTITUTION:An information quantity calculation circuit 1 calculates the information quantity of picture information or activity from an input terminal (a). Then a coded mode table 2 based on the information quantity or the like outputs the efficient mode information and a data with a quantized width whose picture quality deterioration is not visually remarkable. A quantizer 5 quantizes the picture information from a frame memory 4 with a quantized width from the table 2 and outputs the result to an output terminal (b) via a variable length coding circuit 3. Thus, when the information quantity calculated by the circuit 1 is too much, the coding mode is selected from the table 2 so as to reduce it and when the information quantity is less, the coding mode is selected from the table so as to increase the quantity. Thus, easily efficient coding is attained.

Title: Data compressing and encoding device
Inventor: FURUHASHI MAKOTO
IPC: H03M7/32
Filed: 1990-03-20
Abstract: PURPOSE:To enable real-time encoding by switching and selecting the output from a system equipped with the second filter system by a switching means when encoding can not be executed in a system equipped with the first filter group. CONSTITUTION:When overflow is generated, a noise shaping circuit 22 in the system equipped with a first filter group 2 supplies an overflow signal to a switch 24 so as to show the generation of overflow. When this overflow signal is supplied, the switch 24 is changed over from a terminal 24a to be selected to a terminal 24b to be selected. Therefore, the audio data to be supplied to the terminal 24b to be selected is passed through a second filter group 3 where encoding is hardly disabled. Accordingly, by changing over the switch when overflow is generated, the data not to generate the overflow can be selected while avoiding the data generating overflowing. Thus, re-encoding is not required and real-time encoding is enabled.
