Bivariate table is spent, corresponding basal rate is selected from etch-recording speed bivariate table, opens imprinting；Run into the CD do not tested in advance
Or during CD-ROM drive, into low speed recording modes, imprinting success is ensured with maximum probability；
According to the logical address of current optical disc imprinting, current imprinting orbit radius is conversed in real time, into after deceleration area
The just time interval between the gradual each bag engraving data of increasing, indirectly on the basis of current etch-recording speed, progressively
Etch-recording speed is lowered, ensures to proceed to the stability of final stage in imprinting.
The present invention has the advantages and positive effects of：
The embedded video recording equipment of the present invention possesses multiple SATA interfaces, can access multiple CD-ROM equipments, is calculated in software
Under the support of method, it is possible to achieve the speed of dynamic control CD burning, bad rate is carved to achieve the purpose that to reduce CD.The present invention carries
High single-deck and polydisc（More CD-ROM drives）The success rate of imprinting at the same time, lifting means work efficiency, reduces CD and wastes.Commercially
CD-ROM drive and in the case that disc types are various, quality is uneven, increases embedded device to different brands CD-ROM drive and difference
The compatible scope of brand CD, after solving hot plug replacement CD-ROM drive, keeps imprinting success rate not decline.
Brief description of the drawings
Fig. 1 is the hardware system block diagram of the embedded video recording equipment of one embodiment of the invention.
Embodiment
Referring to the drawings with specific embodiment to the dynamic control CD burning on embedded video recording equipment of the invention
The method of speed is described in detail.Specific embodiments described below is only the preferred forms of the present invention, and cannot
It is interpreted as limitation of the present invention.
The method of dynamic control CD burning speed on embedded video recording equipment of the present invention, comprises the following steps：
The brand of CD and the type of CD in identification CD-ROM drive in real time；
The plug of dynamic monitoring CD-ROM drive, identifies CD-ROM drive specification and brand；
On embedded video recording equipment, it is combined according to current CD-ROM drive specification, brand with the CD being currently put into, from
Dynamic select goes out adaptive imprinting speed in etch-recording speed bivariate table；
As the content for being carved into CD gradually increases, and the continuous increase of the imprinting orbit radius of CD, dynamic reduce
The speed of imprinting.
One specific embodiment is as follows：
Fig. 1 is the hardware system block diagram of the embedded video recording equipment of one embodiment of the invention.The main body of the system is embedded
Formula DVR/NVR/ mixed type DVR embedded devices.The equipment provides " SATA mouths 1 ", " multiple CD-ROM drives such as SATA mouths 2 ", " USB port "
Interface, can support monochromatic light drive or the imprinting at the same time of more CD-ROM drives.
Embedded digital video recorder (DVR)/NVR/ mixed type DVR equipment accesses portable CD-ROM drive by its usb interface, there is provided user's operation is set
Standby hardware interface.In this hardware plan, embedded device can provide multiple usb interfaces, can independently access, also can be at the same time
Access, can not also access.
Other parts in embedded digital video recorder (DVR), NVR, mixed type DVR hardware plans, such as power supply, simulation shooting and IPC, equipment
Encoding and decoding and Master control chip etc., as the basic content in device hardware scheme, be not described in detail one by one in the application.
Carving method based on the hardware system is as follows：
Software is opened the entrance of separate threads poll CD and is exited, and instructs the MediaID for obtaining CD (suitable with MMC
In vendor id) and optical disc types（DVD+R, DVD-R, BD-R etc.）.
The driving event of snoop-operations system, after CD-ROM drive insertion, carries out initialization operation, is instructed by MMC and read CD-ROM drive
Etch-recording speed list, the information such as manufacturer ID.
According to the specification of the type of CD, brand and CD-ROM drive, brand, an etch-recording speed two dimension can be combined into advance
Table, reads in when being started by imprinting program, and schematic table is as shown in table 1, and suitable basis speed is therefrom selected starting imprinting program
Degree（Usually represent to be written as 4x, 6x, 8x etc. with speed）, open imprinting.
Table 1
Note：Speed in form needs early period in actual embedded digital video recorder (DVR), NVR, mixed type DVR equipment, by and tool
CD-ROM drive and the CD collocation of body are drawn with experimental data, while retain one " and acquiescence " option, it is prior when being run into actual scene
When the CD or CD-ROM drive do not tested, into low speed recording modes, using etch-recording speed minimum in etch-recording speed bivariate table into
Row imprinting, ensures imprinting success with maximum probability.
According to the logical address of current optical disc imprinting, the orbit radius being currently carved into is conversed in real time, into after deceleration area
Just with the gradual time interval increased before each bag engraving data, indirectly on the basis of current etch-recording speed, progressively
Etch-recording speed is lowered, ensures to proceed to the stability of final stage in imprinting.
Linear transformation formula：Current radius=optical disc logic address * k
K is related with optical disc types for coefficient, and DVD is generally 5/1000ths, and Blu-ray Disc is generally 20/1000ths.
General CD is divided into central ring from the inside to the outside, capacity record starting inner ring, deceleration area, capacity record starting outer ring and
Extension diameter.The orbit radius of central ring is 15mm, and the orbit radius of capacity record starting inner ring is 44mm to 50mm, extension
The orbit radius of diameter capacity record starting outer ring is 76-77mm or 116-117mm, and deceleration area is to be risen close to capacity record
Beginning outer ring region, its orbit radius be 40-77mm either 60-117mm extensions diameters orbit radius be 80mm or
120mm。
