Abstract:
A method of capturing and storing digital HDTV signals comprising the steps of:filling each of four first in-first out registers with data in an 8-bit per device sequential fashion at a constant flow rate until they are half full, transferring said data to system memory as 32 bit words, filling each of said four first in-first out registers with said data in an 8-bit per device sequential fashion at a constant flow rate in a quantity equal to half filling said first in-first out registers, transferring said data to system memory as 32 bit words, filling a first of 2 concurrent blocks of system memory with said data presented to said system memory, filling a second of 2 concurrent blocks of system memory with said data presented to said system memory, writing said data from said first of 2 concurrent blocks of system memory as said second of 2 concurrent blocks of system memory is filling, writing said data from said second of 2 concurrent blocks of system memory as said first of 2 concurrent blocks of system memory is filling, and the transfer of said 32 bit data words being accomplished at a faster rate than the input of said 8-bit data.
