Embodiment
To combine specific embodiment and accompanying drawing that high definition player of the present invention is described in further detail below.
As shown in Figure 1, among the embodiment, high definition player of the present invention mainly comprises encoding and decoding processing module, audio frequency and video processing module, MHL/HDMI multiplexing process module, network process module, remote control wake module and micro controller module.
Micro controller module links to each other with the power module of high definition player, is used to control the electrifying timing sequence of other module of high definition player, thereby it is normal to reach the system program initialization.
Network process module is used to make high definition player to realize function of surfing the Net.The remote control wake module is used to realize the communication between encoding and decoding processing module and the remote controller, receives from the user input signal of high definition player control panel and sends to the encoding and decoding processing module.
The encoding and decoding processing module is with network process module, MHL/HDMI multiplexing process module and carries out encoding and decoding from the multi-medium data of memory (DDR memory or Flash memory etc.) and handle; And the data after will handling are exported to video processing module; And video processing module is with decoded data process HDCP (High-bandwidth Digital Content Protection; The HDCP technology) encrypts; Carry out exporting from component vide, HDMI (High-definition Digital Multimedia Interface, high-definition digital multi-media signal) after DAC (analog to digital conversion) conversion process.
It is MHL (Mobile High-Definition Link that MHL/HDMI multiplexing process module is used for detecting the signal of importing automatically; Portable terminal high-definition audio and video standard interface) signal still is the HDMI signal; If the signal of input is the MHL signal then notifies the encoding and decoding processing module, output to the encoding and decoding processing module after by encoding and decoding processing module control MHL/HDMI multiplexing process module the MHL signal that receives being carried out Signal Separation and data packet analysis processing and synthesizes the HDMI signal; If detecting the signal of input is the HDMI signal; Then MHL/HDMI multiplexing process module is notified the encoding and decoding processing module; By encoding and decoding processing module control MHL/HDMI multiplexing process module the HDMI signal that receives is carried out outputing to the processing of encoding and decoding processing module after HDCP (High-bandwidth Digital Content Protection, the HDCP) verification.MHL/HDMI multiplexing process module is supported quick control standard communications protocol, thereby the user can control user friendly operation through the remote controller of high definition player to connected MHL equipment.
As shown in Figure 2; Among one embodiment; MHL/HDMI multiplexing process module comprises differential signal input and MHL signal input module, MHL/HDMI signal identification separation module, MHL signal processing module, HDMI signal processing module, HDMI signal synthesizing module, differential signal output module and I2C (Inter-Integrated Circuit, internal integration circuit) driver module.Wherein, MHL/HDMI signal identification separation module links to each other with the encoding and decoding processing module through the I2C driver module with the MHL signal processing module.The I2C driver module is controlled by the encoding and decoding processing module through SDA, SCL signal and the communication of encoding and decoding processing module.
Differential signal input is used to receive from the output signal of outside MHL equipment or HDMI equipment and with the signal that receives with the MHL signal input module and outputs to MHL/HDMI signal identification separation module.
It is MHL signal or HDMI signal that MHL/HDMI signal identification separation module is used to discern the signal that receives; And recognition result sent to chief editor's decoding process module through the I2C driver module, the control signal according to chief editor's decoding process module sends to MHL signal processing module and HDMI signal processing module respectively with MHL signal and HDMI signal then.The method of identification MHL signal and HDMI signal can be: because the 18th pin of MHL interface is earth-free; If there is MHL equipment to insert; Because MHL equipment has individual pull-up resistor on its 18 pin; So when the input of MHL signal was arranged, this pin can become high level, thereby can discern the MHL signal of input.If when the input of HMDI signal was arranged, this pin was a low level, be identified as the input of HMDI signal.
The MHL signal processing module is used for after chief editor's decoding process module is the HDMI signal with the MHL conversion of signals under through the control of I2C, sending to the HDMI signal synthesizing module.
The HDMI signal processing module is used under the control of chief editor's decoding process module, the HDMI signal being carried out the HDCP verification, sends to the HDMI signal synthesizing module after the verification succeeds.
It is to output to chief editor's decoding process module through the differential signal output module behind the TMDS signal that the HDMI signal synthesizing module is used for the HDMI conversion of signals that receives.
On high definition player is logical behind the civil power, power module converts civil power the direct current of 5V into, offers micro controller module work, and this moment, micro controller module can receive button and remote signal.After the start key of high definition player was pressed, micro controller module powered on for other modules by setting through the control power module in proper order.After power supply was normal, system carried out initialization, and hardware carries out corresponding configuration, and the kernel of decoding chip starts, other hardware that initialization is peripheral, and after the completion, again that equipment FLASH is inner software accesses, and is put in the DDR and moves, and machine system starts and finishes.
Behind normal boot-strap; If MHL equipment in the connection (like mobile phone etc.); MHL/HDMI multiplexing process module can detect MHL equipment automatically, chooses the input of MHL equipment, and the content that the HDMI output of encoding and decoding processing module control audio frequency and video processing module automatically switches to MHL equipment shows.Can select and import corresponding information to MHL equipment through the remote controller of high definition player through RCP function user, and on the display device that high-definition content is shown to high definition player links to each other with MHL equipment.
So; High definition player of the present invention is provided with the MHL/HDMI multiplexing process module that can discern MHL () signal and HDMI signal automatically; Thereby making has MHL (Mobile High-Definition Link; Portable terminal high-definition audio and video standard interface) mobile device of function can be used as the input source of high definition player like mobile phone, uses more flexibly, convenient.
The above embodiment has only expressed several kinds of execution modes of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with accompanying claims.
