Patent ID: 7689101

Claim:
A video audio recording system comprising: an inputting means for inputting video audio information; a video audio coding means for converting the input video audio information into digital information to write into a buffer means once, and then reading the written video audio information sequentially to output; a signal processing means for converting the video audio information output from the video audio coding means into a optical-disc writable format to write on an optical disc; and a controlling means for controlling a buffer means, wherein the controlling means monitors a write address and a read address of the buffer means and also monitors a buffer value of NV_PCK or RDI_PCK to be written into the buffer means in compliance with each recording mode of a DVD video mode or a DVD-VR mode and a buffer value of NV_PCK or RDI_PCK to be processed in the buffer means, then reduces a writing rate into the buffer means and continues a writing if a difference between the write address and the read address is smaller than a predetermined reducing threshold or if a positional difference between both buffer values is smaller than a predetermined reducing specified value, then brings only the writing of information into the buffer means into a stop condition if at least one of a condition that the difference between the write address and the read address is smaller than a predetermined stop threshold and a condition that the positional difference between the buffer value of NV_PCK or RDI_PCK to be written into the buffer means and the buffer value of NV_PCK or RDI_PCK to be processed in the buffer means is smaller than a predetermined stop specified value is satisfied under the continued condition, and then starts the writing of information into the buffer means once again if the difference becomes larger than a predetermined start threshold and if the positional difference becomes larger than a predetermined start specified value.
