Abstract

A light storing and recording system comprises integrated coder, the first external storage coupled to the first storing controller in said coder and the second external storage coupled to the secondstoring controller in said coder. The said integrated coder consists of light storing controller coupled to light storing media and data coder coupled to light storing device, the first storage arbitration module for selectively making direct access from the first external storage and the second external storage arbitration module for selectively making direct access from the second external storage through data coder and light storing controller.

Description

technical field [0001] The invention relates to an optical storage and recording system, especially a common memory structure suitable for a rewritable digital storage disc system (DVD RW) and a related processing method. Background technique [0002] figure 1 It is a schematic diagram of a known optical storage recording system 10 , the system 10 includes a rewritable digital storage optical drive 11 , a moving picture compression standard (MPEG) encoding subsystem 15 , and a television (TV) decoding subsystem 111 . The rewritable digital storage drive 11 comprises an optical storage device 101, a storage controller such as a read-only / flash controller (Ctlr) 12, a rewritable digital storage drive controller 13 coupled to the optical storage device 101, and another storage control controller, for example: dynamic random access memory (DRAM) controller 14. The controller 12 is coupled to a rewritable digital storage drive controller 13 and an external memory (Ext), such as...
