Please refer to Fig. 2, this figure is the operational flowchart with projecting apparatus of displaying contents and the synchronous recording compression function of sound.Describe below in conjunction with this figure.
Step 301 powers on, and starts projecting apparatus.
Step 302, os starting shows interface of main menu on the operation display interface.
After powering on; The central processing unit 206 of projecting apparatus is from memory module 214 loading processing device start-up routines; After the start-up routine operation, central processing unit is from memory module load operation system kernel, after operating system gets up; The operation interface that on operation display interface 209, can show main menu is used for the present operating state of displaying projector.
On the main menu operation interface of operation display interface 209, can select graph data to come from simulation SD video interface module 202, simulation HD video interface module 203 or digital high-definition video interface module 204.This selection course can realize through control button 210 or remote controller 212.
Step 304, sound and graph data that whether compression memory is imported.
If the sound and the graph data of compression memory input call audio frequency and video compression module 213 through controling button 210 or remote controller 212; If the sound and the graph data of compression memory input do not stop to call audio frequency and video compression module 213 through controling button 210 or remote controller 212, directly video output interface 207 is exported in this video data bypass, voice data abandons and does not handle.
Whether step 305 directly deposits in the USB movable storage device with sound and figure packed data.
Central processing unit 206 can be cached in memory module 214 with sound and the graph data after the compression, in the USB movable storage device that also can the sound after compressing and graph data directly be stored in insertion.Directly deposit in the benefit of USB movable storage device; When projecting apparatus finishes; Sound after the compression and graph data have also been deposited in the USB movable storage device fully; So just saved, sound and graph data after the compression have been exported to the time the USB movable storage device from memory module 214.
If select sound and figure packed data are deposited in the USB movable storage device, then need insert the USB movable storage device.
Insert after the USB movable storage device, can start the control of compression memory, call audio frequency and video compression module 213.
Step 308, record finish after, control button or remote controller, stop to record, extract the USB movable storage device.
After projection process finishes, through controling button 210 or remote controller 212, can stop the compression memory process, when the 209 prompting compression memory work of operation display interface finish, can extract the USB movable storage device.
Step 309 starts compression memory.
If select sound and figure packed data not to be deposited in the USB movable storage device, then can directly start the control of compression memory, call sound and figure compression module 213, sound and graph data directly are stored in memory module 214.
Step 310, record finish after, control button or remote controller, stop to record.
After projection process finishes, through controling button 210 or remote controller 212, can stop the compression memory process, when the 209 prompting compression memory work of operation display interface finish, can carry out next step operation.
Step 311 is inserted the USB movable storage device, and sound after recording and figure packed data are exported in the USB movable storage device, extracts the USB movable storage device then.
If sound after selection will be recorded through the USB movable storage device and figure compression copy out; Then only need to insert the USB movable storage device; Log-on data derives operation; Can export to the USB movable storage device to sound and the graph data after the compression, when the 209 prompting derivation work of operation display interface are accomplished, can extract the USB movable storage device.
Step 312 connects netting twine, and sound and figure packed data after recording are derived through network in the IP address of input projecting apparatus.
If sound after selection will be recorded through network and figure packed data are derived, then only need connect netting twine, configuration connects the IP address of the computer of projecting apparatus; Make itself and the IP address of projecting apparatus belong to the same network segment, and dispose corresponding subnet mask, default gateway; After configuration finishes; The network entry projecting apparatus can be passed through in the IP address of input projecting apparatus in the browser address, derives sound and figure packed data after recording through network.
