Method and apparatus for performing continuous capture during recording real-time data
View Patent ↗An encoder encodes the captured real-time data into a program stream. A disk authoring transforms the program stream into a disk file format. A disk writer records the disk file format on an optical disk, wherein the disk writer further includes at least two recording speeds. A buffer temporarily stores the program stream or the disk file format during the disk writer stopping the recording action. A sending-path controller notified by the disk writer to switch the data flow between the disk authoring or the disk writer and the buffer, wherein the sending-path controller also can notify the disk writer to switch the recording speeds.
1. An apparatus for performing continuous capture during recording real-time data, said apparatus comprising: an encoder encoding captured real-time data into a program stream; a disk authoring transforming said program stream into a disk file format; a disk writer connecting with said disk authoring and recording said disk file format on an optical disk; a buffer connecting with said disk authoring and temporarily storing said program stream; and a sending-path controller having data inputs connecting with said encoder for receiving said program stream, having first data outputs connecting with said disk authoring for directly transmitting said program stream, and having second data outputs connecting with said buffer for temporarily storing said program stream, wherein said sending-path controller is notified by said disk writer to switch a data flow path between said first data outputs and said second data outputs.
2. The apparatus according to claim 1 , wherein said buffer further comprises a system memory and a hard disk.
3. The apparatus according to claim 1 , wherein said disk writer further has a high recording speed being faster than a normal recording speed thereof.
4. The apparatus according to claim 3 , wherein said normal recording speed and said high recording speed are triggered by said sending-path controller.
5. The apparatus according to claim 4 , wherein said normal recording speed is used for recording said disk file format transmitted from said sending-path controller.
6. The apparatus according to claim 4 , wherein said high recording speed is used for recording said disk file format transmitted from said buffer.
7. The apparatus according to claim 1 , wherein said disk writer notifies said sending-path controller to switch said data flow path from said disk authoring to said buffer while said disk writer stops recording.
8. The apparatus according to claim 1 , wherein said disk writer notifies said sending-path controller to switch said data flow path from said buffer to said disk authoring while said buffer is empty of said program stream and said disk writer resumes recording.
9. An apparatus for performing continuous capture during recording real-time data, said apparatus comprising: an encoder encoding captured real-time data into a program stream; a disk authoring connecting with said encoder and transforming said program stream into a disk file format; a disk writer recording said disk file format on an optical disk; a buffer connecting with said disk writer and temporarily storing said disk file format; and a sending-path controller having data inputs connecting with said disk authoring for receiving said disk file format, having first data outputs connecting with said disk writer for directly transmitting said disk file format, and having second data outputs connecting with said buffer for temporarily storing said disk file format, wherein said sending-path controller is notified by said disk writer to switch a data flow path between said first data outputs and said second data outputs.
10. The apparatus according to claim 9 , wherein said buffer further comprises a system memory and a hard disk.
11. The apparatus according to claim 9 , wherein said disk writer further comprises a high recording speed being faster than a normal recording speed thereof.
12. The apparatus according to claim 11 , wherein said normal recording speed and said high recording speed are triggered by said sending-path controller.
13. The apparatus according to claim 12 , wherein said normal recording speed is used for recording said disk file format transmitted from said sending-path controller.
14. The apparatus according to claim 12 , wherein said high recording speed is used for recording said disk file format transmitted from said buffer.
15. The apparatus according to claim 9 , wherein said disk writer notifies said sending-path controller to switch said data flow path from said disk writer to said buffer while said disk writer stops recording.
16. The apparatus according to claim 9 , wherein said disk writer notifies said sending-path controller to switch said data flow path from said buffer to said disk writer while said buffer is empty of said disk file format and said disk writer resumes recording.
