In the present embodiment, processing unit 114 can access the line stored by storage element 112 and establish module 112_1,
One decision module 112_2, the second decision module 112_3, execution module 112_4 and transmission module 112_5 are to execute the present invention
Each step of the method for the implementation mobile high definition transmission technology of proposition.
Fig. 2 is the method flow diagram for the implementation mobile high definition transmission technology that embodiment is painted one of according to the present invention.This reality
The method for applying example proposition can execute by the electronic device 110 of Fig. 1, and i.e. each element in conjunction with Fig. 1 illustrates this method below
Detailed step.
In step S210, line establish module 112_1 can with destination apparatus 120 execute signal exchange program with target
Device establishes mobile high definition transmission (mobile high-definition link, MHL).In the present embodiment, electronic device
It can be connected by MHL connecting lines L1 between 110 and destination apparatus 120, and MHL connecting lines L1 can be embodied as 1 pair 1 of connection
Form (as shown in the bold portion of MHL connecting lines L1).It is noted that MHL connecting lines L1 can also be embodied as 1 pair 2 of company
Form (for example, Y types connecting line) is connect, to allow electronic device 110 that can be connected to destination apparatus 120 and computer apparatus simultaneously
130.Computer apparatus 130 is selected from PC, laptop, server or other similar devices.
In the signal exchange program, line, which establishes module 112_2, to carry out HDCP golden key signals with destination apparatus 120
Exchange, confirm and show resolution and confirm whether electronic device 110 supports the behaviors such as packed-pixel pattern, but the present invention can
Embodiment is without being limited thereto.
In step S220, the first decision module 112_2 can determine to use common mould based on the result of signal exchange program
Formula or packed-pixel pattern transmit data to be transmitted.The data to be transmitted can be audiovisual materials etc..In one embodiment,
When the display resolution confirmed in signal exchange program is 1080i, general mode transmission can be used in the first decision module 112_2
Data to be transmitted.On the other hand, when the display resolution is 1080p, packed-pixel can be used in the first decision module 112_2
Pattern transmits data to be transmitted.
It is to be understood that and not all electronic device 110 all support packed-pixel pattern.Therefore, in one embodiment,
When electronic device 110 does not support packed-pixel pattern, it is to be passed that the first decision module 112_2 can directly use general mode to transmit
Defeated data.
In addition, in other embodiments, when the instruction of the result of signal exchange program is using general mode, first determines mould
Block 112_2 still can be used packed-pixel pattern and transmit data to be transmitted.Even if that is, in the signal exchange program
The display resolution of confirmation is 1080i, and the first decision module 112_2 can not still use the general mode corresponding to 1080i, and straight
It connects and data to be transmitted is transmitted using the packed-pixel pattern with higher bandwidth (that is, 3G bps).
In the case, due to electronic device 110 only need 2.25G bps bandwidth can data to be transmitted, electricity
Sub-device 110 can transmit other data using extra bandwidth, and then promote the flexibility in the implementation of MHL technologies.With Fig. 1
For, when electronic device 110 by MHL connecting lines L1 (that is, bold portion) transmitting audio-video data to destination apparatus 120 when, electricity
Sub-device 110 more can transmit other data using extra bandwidth above-mentioned by MHL connecting lines L1 (that is, dotted portion)
(such as documentation etc.) is to computer apparatus 130.Thus, which audiovisual materials transmission and charging can only be realized by being different from tradition
The MHL technologies of function, the method that the embodiment of the present invention proposes can completely utilize workable bandwidth, and then allow electronic device
110 can carry out data exchange by Y types connecting line and destination apparatus and computer apparatus simultaneously.
Referring once again to Fig. 2, in step S230, the second decision module 112_3 decides whether to execute bandwidth decrement mechanism.
If so, in step S240, execution module 112_4 executes bandwidth and is reduced mechanism to compress data to be transmitted；If it is not, in step
In S250, transmission module 112_5 can transmit the data to be transmitted.
As previously mentioned, data to be transmitted can be audiovisual materials, and general audiovisual materials are the formats with frame
It presents.Therefore, execution module 112_4 can compress data to be transmitted by specific image processing mode, to allow transmission to wait for
Data quantity when data transmission can effectively decline.
In one embodiment, electronic device 110 can further include the buffer 116 for being connected to processing unit 114, to store
It is associated with multiple frames of aforementioned audiovisual materials.For convenience of explanation, data to be transmitted is known as present frame in the present embodiment, and
Each frame prior to the present frame is referred to as previous frame.The previous frame can be generation time earlier than the present frame
Frame.It is to be understood that the present frame and each previous frame can be stored in buffer 116.
When electronic device 110 needs to transmit present frame to destination apparatus 120, execution module 112_4 can access buffer
An at least previous frame in 116, and the present frame and an at least previous frame, to find out the present frame phase
For multiple update area of an at least previous frame.The update area is present frame with an at least previous frame not
Same place.The update area corresponds to the moving target (motion object) in present frame.Then, execution module
The present frame is cut into multiple microliths (microblock) by 112_4 according to the respective size of the multiple update area.Institute
It includes multiple particular blocks corresponding to the multiple update area to state multiple microliths.Later, execution module 112_4 can record it
In multiple particular blocks and the multiple particular block respective positions information and dimension information.
By taking Fig. 3 A as an example, Fig. 3 A be one of according to the present invention embodiment be painted present frame is cut into showing for multiple microliths
It is intended to.In this example, it is assumed that update area 312 is update area of the present frame 310 relative to its previous frame.Therefore, it holds
Present frame 310 can be cut into microlith MB1~MB3 by row module 112_4 according to the size of update area 312.Due to MB1 pairs of microlith
Should be in update area 312, therefore microlith MB1 can be described as particular block.
In the present embodiment, execution module 112_4 can record the location information and dimension information of microlith MB1.Institute's rheme
Confidence breath is coordinates of the microlith MB1 in present frame 310, and the dimension information is the corresponding pixel block sizes of microlith MB1.
Again by taking Fig. 3 B as an example, Fig. 3 B be one of according to the present invention embodiment be painted present frame is cut into multiple microliths
Schematic diagram.In this example, it is assumed that update area 314~318 is update area of the present frame 320 relative to its previous frame.
Therefore, execution module 112_4 can according to update area 314~318 size by present frame 320 be cut into multiple microliths (such as
It is 4x3 microlith).Since microlith MB1 '~MB3 ' corresponds respectively to update area 314~318, microlith MB1 '~MB3 '
It can be described as particular block.
In the present embodiment, execution module 112_4 can record microlith MB1 '~MB3 ' respective positions information and size
Information.The location information is microlith MB1 '~MB3 ' respective coordinates in present frame 320, and the dimension information is microlith
The corresponding pixel block sizes of MB1 '~MB3 '.
Referring once again to Fig. 2, in step s 250, transmission module 112_5 can transmit data to be transmitted.It is to be understood that
If electronic device 110 is if directly executing step S250 after step S230, transmission module 112_5 can be in step s 250
Directly transmission (unpressed) data to be transmitted.That is, present frame directly can be transmitted to target dress by transmission module 112_5
Set 120.
On the other hand, if electronic device 110 is if sequentially executing step S230, S240 and S250, transmission module
112_5 can transmit in step s 250 the multiple particular block and the multiple particular block respective positions information and
Dimension information.In the case, destination apparatus 120 can be corresponded to according to particular block and its information from electronic device 110
Ground executes specific mechanism to restore present frame on destination apparatus 120.
For example, the buffer for storing multiple previous frames is may also include on destination apparatus 120, and works as destination apparatus
120 when receiving the multiple particular block and the multiple particular block respective positions information and dimension information, target
The part for corresponding to particular block in previous frame can be substituted by each particular block by device 120, and then restore present frame.
In other words, transmission module 112_5 is not required to present frame being transmitted to destination apparatus 120, it is thus possible to efficiently reduce
Transmit bandwidth required when data to be transmitted.Thus, which remaining bandwidth can be used for transmission other by electronic device 110

It is higher than 1080p in the resolution of this audiovisual materials, therefore, packed-pixel mould can be used in electronic device 110 and destination apparatus 120
Formula is transmitted.It in the case, can if the executable step S240 of execution module 112_4 are to compress audiovisual materials
Required bandwidth when efficiently reducing transmitting audio-video data.Thus, electronic device 110 just can using remaining bandwidth come
Data transmission is to computer apparatus 130, to reach the function that traditional MHL technologies are unable to reach.
In a second embodiment, it is assumed that data to be transmitted is to be characterized as 1920x1080 (resolution), the audio-visual money of 30Hz

Audiovisual materials are transmitted to destination apparatus 120 in the case of seldom bandwidth.Thus, which electronic device 110 can will be remaining
Bandwidth is for transmitting data to computer apparatus 130, to reach the data transmission effect of high speed.
It is worth noting that, in the third embodiment, it is assumed that the picture of electronic device 110 does not become (that is, being associated with spy completely
The data quantity for determining block is that 0), then electronic device 110 can allow the display of destination apparatus 120 that should present without the use of any bandwidth
Picture.Thus, which electronic device 110 can be by all bandwidths for transmitting data to computer apparatus 130, thus reach more
The data transmission effect of high speed.
