Fig. 2 B is the functional block diagram showing according to the display system 200B of further embodiment of this invention.Please also refer to Fig. 2 A and Fig. 2 B, subelement function in display system 200B is identical with the element in display system 200A, for example, be storage element 260B (comprising operating system 261B, the first driver 262B and the second driver 263B) and USB display device 270B.The difference of display system 200B and display system 200A is that display system 200B uses a platform control hub (Platform Control Hub, PCH) 290 for example, in order to replace the part function (real-time clock) of the north bridge chips 231A in script display system 200A and the repertoire of South Bridge chip 232A, and processor 210B is connected with platform control hub 290 by a direct media interface (Direct Media Interface, DMI).Processor 210B (being for example Intel i3, i5, i7 processor), it comprises that the first core 211B, the second core 212B and one integrate Memory Controller 213B, and wherein the function of the first core 211B and the second core 212B is identical with the first core 211A and the second core 212A respectively.What note is, memory cell 240B in display system 200B is that the integration Memory Controller directly and in processor 210B is electrically connected, and memory cell 240B uses to integrate memory architecture (Unified Memory Architecture), pass through to integrate the data in Memory Controller 213B access memory unit 240B for the first core 211B (generally processing arithmetic core) and the second core 212B (graphics process core).
For purposes of the invention, no matter be display system 100,200A or 200B, all can be play by USB display device the video file of the high image quality resolution with content protecting.For ease of explanation, embodiment described later is take the display system 100 of Fig. 1 as example.Those of ordinary skills are when understanding the operational applications of display system 100 of the present invention in display system 200A and 200B.
Fig. 3 is the schematic diagram of demonstration according to the software/hardware framework of the display system 100 of one embodiment of the invention.Please also refer to Fig. 1 and Fig. 3, the treatment scheme of the software/hardware of display system 100 (or display system 200A, 200B) is broadly divided into totally 5 stages in stage 310～350.Stage 310 also can be described as the unprotected architecture of user's pattern (User mode unprotected infrastructure).For instance, in the stage 310, display system 100 can such as, have the video file of content protecting (for example AACS encrypts) by playout software (Power DVD, Media Player etc.) broadcasting.Then, processor 110 is decrypted the video content (comprising the first encrypted audio stream and the first encrypted video stream) with content protecting, and enters the stage 320.
Should be noted in the stage 310～320, is all the parts that belong to software, even if meaning is carried out relevant encryption and decryption operation with processor 110.Graphic process unit 120 also has special hardware circuit (for example H.264 demoder) can decode to video flowing, but still need utilize the first driver 162 to control to operate.More specifically, the core schema in the stage 330, the first driver 162 can utilize processor 110 and graphic process unit 120 for example, to decode to video flowing (H.264 video flowing).In other words, graphic process unit 120 and the first driver all can be in order to decoding video streams.
To utilize processor 110 to be encrypted (for example using AES to encrypt) from the original video data of the first driver 162 at stages 340, the second driver 163, and the original video data after encrypting is sent to USB display device 170.USB display device 170 is decoded to the original video data being received after encrypting again, and by the original video data of decoding gained by simulation display interface or digital display interface is sent to display (not illustrating), and enter the stage 350.Because USB display device 170 can be decrypted to obtain original video data to received encryption original video data, so no matter USB display device 170 is play original video data by simulation display interface or digital display interface on display all can not be restricted, meaning can show the picture depression of order of high image quality resolution.In the stage 350, display can be play-overed the original video data from USB display device 170.Those of ordinary skills are when understanding; the present invention also can select traditional approach, by graphic process unit 120 or its first driver 162, video flowing is decoded to obtain video data; and by graphic process unit 120 by simulation display interface (for the video content of the high image quality resolution of meaningful protection, need by resolution depression of order) or digital display interface playing video data on display.
Fig. 4 shows according to the process flow diagram for the display packing of display system 100 in one embodiment of the invention.Please also refer to Fig. 1 and Fig. 1.At step S410, processor 110 is for example, to for example, decipher to obtain one first video flowing (H.264 video flowing) with one first encrypted video stream of one first encryption and decryption standard (the advanced access content system of AACS encryption and decryption standard), and for example, with one second encryption and decryption standard (the advanced encryption and decryption standard of AES) this first video flowing encrypted to obtain one second encrypted video stream.At step S420, processor 110 is carried out the first driver 162 the second encrypted video stream is deciphered to obtain one second video flowing (for example H.264 video flowing).At step S430, graphic process unit 120 and the first driver 162 decode to obtain a video data to this second video flowing.At step S440, the second driver 163 is encrypted to obtain enciphered video data by processor 110 to the video data of decoding gained, and enciphered video data is sent to USB display device 170.At step S450, USB display device 170 is decrypted to obtain original video data to received enciphered video data.At step S460, USB display device 170 can be play in a display video data of deciphering gained.
Fig. 5 shows according to the process flow diagram for the display packing of display system 200A or 200B in another embodiment of the present invention.Please also refer to Fig. 2 and Fig. 5, describe in this embodiment as an example of display system 200A example, how those of ordinary skills can understand the operational applications of display system 200A in display system 200B.At step S510, the first core 211A of processor 210A is for example, to for example, decipher to obtain one first video flowing (H.264 video flowing) with one first encrypted video stream of one first encryption and decryption standard (the advanced access content system of AACS encryption and decryption standard), and for example, with one second encryption and decryption standard (the advanced encryption and decryption standard of AES) this first video flowing encrypted to obtain one second encrypted video stream.At step S520, the first core 211A of processor 210A carries out the first driver 262A the second encrypted video stream is deciphered to obtain one second video flowing (for example H.264 video flowing).At step S530, the second core 212A and the first driver 262A of processor 210A decode to obtain a video data to the second video flowing.At step S540, the second driver is encrypted to obtain enciphered video data by the first core 211A of processor 210A to the video data of decoding gained, and enciphered video data is sent to USB display device 270A.At step S550, USB display device 270A is decrypted to obtain video data to received enciphered video data.At step S560, USB display device 270A can play in a display video data of deciphering gained.
