<p>A method of writing video data rearranged according to their weights and reading the same, in/from a DRAM used as a frame memory in a PDP type TV receiver is described. In the writing method, the DRAM is divided into MSB to LSB row regions for storing MSB to LSB weight data, respectively. A first to 8th sampled video data of a first line are written in a first MSB to a first LSB rows of a first column according to their weights, respectively, and a 9th to 16th sampled video data of a first line are written in a second MSB to a second LSB rows in a first column according to their weights, respectively, so as to be written the video data of the first line according to their weights. The video data of an N-th line are written in an N-th MSB to an N-th LSB rows of an N-th column according to their weights, respectively by performing repeatedly the above process. According to the above method, the video data based on the interlaced/non-interlaced scanning method are written on a frame memory using the DRAM which is relatively cheap and the video data are read from the frame memory, the circuit reliability can be improved and the cost can be reduced.</p> |
