IPC: H04N19/50
Filed: 1992-12-09
Abstract: PURPOSE:To improve the data compression efficiency by the block run length system even when a motion is in existence in picture data in a block. CONSTITUTION:A video signal SV is subjected to block processing and a DCT circuit 2 applies discrete cosine transformation (in-frame DCT) to the signal and coefficient data are quantized by a quantization circuit 5 through a sorting circuit 3 and coded by a variable length coding circuit 6 to obtain code data DT. The sorting circuit 3 applies line rearrangement to a motion block to concentrate energy to a low frequency components apparently. A data quantity calculation circuit 7 calculates data quantity to decide a quantization step width corresponding to a transmission capacity and sets a transmission range of coefficient data of each block thereby implementing buffering control. Motion information Dm, and range setting information Da representing a transmission range are sent as additional bits together with the code data DT. The energy is concentrated to low frequency components apparently by the line rearrangement of coefficient data with respect to a motion block and the data compression efficiency is improved.

Abstract: PURPOSE:To eliminate a high frequency component of 1-bit quantized noise effectively by receiving and integrating an output of an output inhibit device corresponding to a 1-bit quantized data only when a logical value of the 1-bit quantized data from a sigma delta modulator changes. CONSTITUTION:Suppose that a 1-bit quantized data is inputted from a sigma delta modulator to an input terminal 1. Moreover, a clock with a bit period the same as that of a quantized data is inputted to a clock input terminal 5. A latch circuit 2 latches the 1-bit quantized data by one bit period and gives the result to other input terminal of an exclusive OR circuit 3. Thus, the circuit 3 receives a quantized data of >=1 bit, and when the quantized data of >=1 bit is of the same logic, an L level is outputted to a control terminal of a tri- state buffer 4 and when the data is not of the same logic, an H level is outputted. That is, only when the 1-bit quantized data is changed, a buffer 4 is energized to supply the 1-bit quantized data from the terminal 1 to one terminal of a resistor R being a component of an integration circuit.
