PURPOSE:To always execute optimal encoding for input data. CONSTITUTION:This device is provided with a first encoder 1 for encoding input data, a first memory 2 for storing encoded data in a prescribed encoding interval from a first encoder 1, a first counter 3 for counting the encoded data quantity encoded by a first encoder 1, a second encoder 4 for executing encoding which is different from first encoding for the input data, a second memory 5 for storing the encoded data in the prescribed encoding interval from a second encoder 4, a second counter 6 for counting the encoded data quantity encoded by a second encoder 4, and a selector 8 for comparing count values of a first and a second counters at every prescribed encoding interval and fetching the encoded data responding to a smaller count value from one of two memories 2, 5. |
