Abstract:
A device for transmitting video data, comprising:a temporary memory which stores N original blocks of data which are variable length coded such that a plurality of said blocks have different bit rate lengths;a standby memory which sequentially stores N processed blocks such that said N processed blocks each have a bit rate length that is equal to or less than a specified bit rate length and which subsequently outputs said N processed blocks to be transmitted at a fixed bit rate;a bit counter which is operably coupled to said temporary memory and said standby memory, which generates address signals for storing said N original blocks in said temporary memory, and which generates an address signal for storing said N processed blocks in said standby memory; anda controller which is coupled to said bit counter, said temporary memory, and said standby memory, which determines a data state of said N original blocks input to said temporary memory and which uses said data state to control said bit counter to read original data of said N original blocks from said temporary memory at a reading bit rate which is shorter than or equal to said specified bit rate and to write said original data in said standby memory as said N processed blocks.
