ABSTRACT:
The present invention provides a data receiving apparatus constituted in such a manner that the received data is converted into a binary code and this binary code data is encoded and this encoded data is stored in a memory, whereby a large quantity of data can be stored in a memory of a small capacity. After subsequently decoding the received encoded data, this decoded data is further encoded by another encoding means and this encoded data is stored in the memory, thereby providing an efficient and economical data receiving apparatus which can smoothly perform the data processing even in the case where the transmission speed of the data and the recording speed of the recording apparatus remarkably differ.
