Description
Technical field
The invention belongs to the HDCP technical field, relate in particular to method, device and the digital equipment of a kind of HDCP key burning.
Background technology
HDMI (High Definition Multimedia Interface, HDMI (High Definition Multimedia Interface)) is that a kind of full digitisation image and sound transmit interface, can transmit sound signal and the vision signal of not having compression.HDMI can be used for set-top box, DVD player, PC, holder for TV playing, comprehensive enlarger, numerical digit sound equipment and televisor.DVI (Digital Visual Interface, digital visual interface), with the HDMI interface class seemingly, but can only the transmission digital video signal.
HDCP (High-Bandwidth Digital Content Protection, HDCP) can illegally not recorded and occurred for the high-resolution signal that guarantees HDMI or DVI transmission.Support on the playback equipment or display device of HDCP resist technology; all can have a unique HDCP key (Secret Device Keys); this key is to use the array password of 40 groups of 56bit to form; generally leave among the chip of transmitter and receiving end chip manufacturer, for example Silicon Image, Chrontel etc.And each has the equipment of HDCP chip, also can have one group of private key (Device Priivate Key), and this group private key will be formed KSV (Key Selection Vector), and this group KSV is equivalent to the sequence number that this has the HDCP chipset.And the HDCP transmitter is before sending signal, whether will inspect receiving end is legal, at this moment will utilize HDCP key (Secret Device Keys), allow transmitter and receiving end exchange, at this moment both sides will obtain one group of KSV and begin to carry out computing, the result of its computing can allow two sides contrast, if the numerical value that generates conforms to, this transmitter just can confirm that this receiving end is a legal side.In case it is a legal side that transmitter has been determined receiving end, this transmitter just can begin to carry out transmission signal, but at this moment transmitter can add one group of password on signal, receiving end must be decrypted in real time can be correct show image.Unique HDCP key mentioned above is exactly the HDCPKey that we are commonly called as.The Key of every digital equipment is all different, has uniqueness.On the digital equipment that has HDMI or DVI interface, must unique HDCP Key be arranged burning, could guarantee the correct transmission of high-definition digital signal.
Currently dispose in the research and development, manufacture process of the digital product of HDMI and DVI port, realize that the method for the burning of HDCP Key mainly contains three kinds at televisor and other:
1, by interface chip provider with HDCP Key burning in the interface chip of HDMI or DVI, supply equipment manufacturer the time directly selects for use in design.This method can guarantee the uniqueness of every equipment Key sign indicating number, also can conveniently produce.But only have at present part interface chip provider built-in HDCP Key, as the change-over switch chip of HDMI, the decoding chip of main flow does not provide this built-in Key.This just makes and does not pass through the HDMI change-over switch in the digital signal of HDMI, directly enters under the situation of decoding chip, just must be in process of production by equipment manufacturers, and craft is burned again with HDCP Key.Along with the widespread use of HDMI port, the decoding chip that carries a plurality of HDMI ports is also more and more, make the burning of HDCP Key become one in the device fabrication process must step.
2. by equipment manufacturers aborning, use cd-rom recorder that HDCP Key is burnt among the independent EEPROM one by one, again this EEPROM is mounted on the equipment substrate.The benefit of this method is that the operation of HDCP Key burning is independent, and convenience is controlled production procedure.But this method replication rate is slow, inefficiency.Must one by one EEPROM be put in the cd-rom recorder, burning finishes, and marking and packing just can mount on the substrate then again.This method for burn-recording also is difficult to the uniqueness of assurance equipment Key sign indicating number, does not also have trackability, when maintenance, must use a new HDCP Key burned again, causes the waste of resource, increases production cost.
3. assembling and manufacturing substrate by equipment manufacturers, when entering debugging station, use the online burning instrument, under the state of digital equipments such as televisor start, utilize the communication modes of RS232 by computer or scanner, the data of online burned HDCP Key are in televisor or digital equipment.
In sum, prior art HDCP Key method for burn-recording takes time and effort, and efficiency ratio is lower, does not possess trackability, and integrity problem also appears in waste resource easily.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of HDCP key method of burning, and the HDCP Key method for burn-recording that is intended to solve prior art takes time and effort, and efficiency ratio is lower, does not possess trackability, and the problem of integrity problem also appears in waste resource easily.
The embodiment of the invention is achieved in that the method for a kind of HDCP key burning, and described method comprises the steps:
Detect the information whether digital equipment has movable storage device to insert, otherwise output prompting user inserts the information of movable storage device, is then to continue to carry out following steps;
Output prompting user selects the information of the HDCP Key data that need burning that described movable storage device provides; Described movable storage device stores HDCP Key data;
The information of the HDCP Key data that need burning that the described movable storage device that the reception user selects provides;
The described information of the HDCP Key data of burning that needs is burnt in the described digital equipment.
The embodiment of the invention also provides a kind of HDCP key the device of burning, and described device comprises:
The movable storage device detecting unit is used to detect the information whether digital equipment has movable storage device to insert;
First Tip element is used for when described movable storage device detecting unit detects digital equipment and do not have information that movable storage device inserts, and output prompting user inserts the information of movable storage device;
