Abstract
A method and apparatus are disclosed for capturing and storing digital high definition television signals. The signals are taken from an input device in 8-bit parallel fashion at a constant flow rate and put into each of four 8-bit first in-first out memory registers until they are half full. After the respective first in-first out memory registers are half filled, additional quantities of data equal to half filling the registers are added while the data from the first half register filling is presented to the system memory as 32 bit words. That data is filled into a first of two concurrent blocks of system memory and after the first block is filled, while the second block is filled, the data is written from the first of the two concurrent blocks into another part of the system memory. The transfer of the 32-bit data words is accomplished at a faster rate than the input rate of the 8-bit data.
