Refer to Fig. 1, it is a kind of HDMI output resolution ratio changing method provided in the specific embodiment of the invention
The method flow diagram of first embodiment.As it can be seen, the method includes:
Step 101: receive the operational order of switching resolution.
HDMI outfan (i.e. HDMI outut device) receives the operational order of the switching resolution of user's input.Optional
Ground, HDMI outfan is top box of digital machine.
Step 102: HDMI output resolution ratio is switched to new resolution by current resolution.
HDMI output resolution ratio is switched to new resolution by current resolution by HDMI outfan；If now HDMI receives
End supports new resolution, the most normally shows the signal data that HDMI outfan sends under new resolution；And when HDMI receiving terminal
When not supporting new resolution, when HDMI outfan sends signal with new resolution, HDMI receiving terminal cannot be carried out normally showing,
User now cannot see, from HDMI receiving terminal, the signal that HDMI outfan exports, it is seen that be probably mess code, snow etc..Can
Selection of land, HDMI receiving terminal is playing audio/video, and still optionally further, HDMI receiving terminal is television set.
Step 103: if being not received by the confirmation of user's input in preset time period, then by described HDMI output point
Resolution returns described current resolution.
Judge whether to receive the confirmation of user's input in preset time period, (i.e. do not have in preset time period if not
Receive the confirmation of user's input), then described HDMI output resolution ratio is returned described current resolution；If (i.e. existing
The confirmation of user's input is received in preset time period), it is determined that HDMI output resolution ratio handover success, keep differentiating with new
Rate output signal or data.Alternatively, it is judged that whether receive in preset time period user input confirmation, including: sentence
Break in preset time period, whether receive the physics confirmation key command of the remote control equipment that user inputs；Or judge at preset time period
The physics of this equipment the most whether receiving user's input confirms key command.
Alternatively, preset time period is 3 seconds, 5 seconds or 10 seconds etc..When HDMI receiving terminal does not supports new resolution, it is impossible to right
The data signal that HDMI outfan sends shows, and then user cannot be made to know whether, and needs switch over confirmation operation,
Or when switch over confirmation operation；When the duration confirming operation exceedes preset time period, HDMI outfan auto-returned is current
Resolution (output resolution ratio before switching), proceeds normally to show.
In sum, the embodiment of the present invention is by receiving the operational order of switching resolution；By HDMI output resolution ratio by
Current resolution switches to new resolution；If being not received by the confirmation of user's input in preset time period, then by described
HDMI output resolution ratio returns described current resolution.When user switches the HDMI output resolution ratio of HDMI outfan, if
When being not received by the confirmation of user's input in preset time period, then return the output resolution ratio before switching；Solve
HDMI receiving terminal compatibility is bad, the resolution before causing some resolution cannot automatically return to switching when not supporting continue into
The problem of row viewing, significantly improves the viewing experience degree of user.
Refer to Fig. 2, it is a kind of HDMI output resolution ratio changing method provided in the specific embodiment of the invention
The method flow diagram of the second embodiment.As it can be seen, the method includes:
Step 201: receive the operational order of switching resolution.
Step 202: judge that described new resolution is the most identical with described current resolution？
HDMI outfan judges that the new resolution needing switching is the most identical with current resolution；When judging to make new advances resolution
When differing with current resolution, continue executing with step 203；When judge make new advances resolution identical with current resolution time, continuation
Perform step 208.
Step 203: HDMI output resolution ratio is switched to new resolution by current resolution.
When HDMI outfan judges that the new resolution needing switching is to differ with current resolution, HDMI is exported
Resolution is switched to new resolution by current resolution, and preserves current resolution (resolution before switching).
Step 204: send the checking dialog box information comprising switching checking information to HDMI receiving terminal, so that described HDMI
Receiving terminal comprises, described in showing, the checking dialog box information switching checking information.
The content that the HDMI receiving terminal that user is seen by HDMI receiving terminal shows, when HDMI receiving terminal supports new resolution
Time, HDMI receiving terminal normally shows that this comprises the checking dialog box information of switching checking information；User is by HDMI receiving terminal
Display it can be seen that HDMI receiving terminal send comprise switching checking information checking dialog box information.And work as HDMI receiving terminal not
When supporting new resolution, HDMI receiving terminal cannot normally show that this comprises the checking dialog box information of switching checking information, may
Mess code etc. occur, now by the display of HDMI receiving terminal, user cannot see that the switching checking that comprises that HDMI receiving terminal sends is believed
The checking dialog box information of breath.
Alternatively, switching checking information is random code.Described transmission to HDMI receiving terminal comprises testing of switching checking information
Card dialog box information, including: generate random code, send the checking dialog box information comprising random code to described HDMI receiving terminal.
Step 205: judge whether to receive the described switching checking information of user's input in preset time period？
HDMI outfan judges whether to receive the checking information of user's input in preset time period, and determines whether to connect
The checking information of the user's input received is the most identical with the switching checking information that HDMI outfan generates.When switching checking information
During for random code, it is judged that whether receive in preset time period user input confirmation be: judge in preset time period be
The no described random code receiving user's input.Alternatively, it is judged that whether receive in preset time period described in user's input
Random code, including: in preset time period, receive the information of user's input；Judge information that described user inputs and described random code
Whether mate.
When HDMI outfan receives the checking information of user's input in preset time period, and this checking information is defeated with HDMI
The switching going out end generation is verified when information (random code) is identical, proceeds step 207；When HDMI outfan is not when preset
Receive the checking information of user's input in length, or HDMI outfan receives the checking letter of user's input in preset time period
Breath, but the switching that this checking information and HDMI outfan generate is verified when information (random code) differs, and continues executing with step
206。
Step 206: described HDMI output resolution ratio is returned described current resolution, sends prompting institute to HDMI receiving terminal
State HDMI receiving terminal and do not support the information of described new resolution.
When HDMI outfan does not receives the checking information of user's input in preset time period, or HDMI outfan is in advance
Receive the checking information of user's input in putting duration, but the switching checking information that this checking information and HDMI outfan generate is not
Time identical, HDMI output resolution ratio is returned current resolution by HDMI outfan, sends prompting HDMI to HDMI receiving terminal and receives
End do not support the information of new resolution.Such as: the switching checking information that HDMI outfan generates is four identifying codes " Txf5 ",
If user does not input this identifying code, or when the identifying code of input differs with this identifying code, HDMI outfan is by HDMI
Output resolution ratio returns current resolution.
In the case of HDMI receiving terminal does not support new resolution, the signal that HDMI outfan sends under this new resolution
Making HDMI receiving terminal to show or cannot normally show, user cannot know the switching checking information needing input, thus nothing
Method inputs correct checking information in preset time period；In this case, HDMI outfan does not receive in preset time period
To when correctly switching checking information of user's input, assert that now HDMI receiving terminal does not support this new resolution, return current point
Resolution (resolution before switching), and point out described HDMI receiving terminal not support to the transmission of HDMI receiving terminal under current resolution
The information of this new resolution, informs that user's HDMI receiving terminal does not support this new resolution.User can proceed viewing, and knows
The reason that road resolution cannot switch, effectively raises the viewing experience degree of user.
Step 207: determine HDMI output resolution ratio handover success, keeps being exported by described new resolution.
When HDMI outfan receives the checking information of user's input in preset time period, and this checking information is defeated with HDMI
The switching going out end generation verifies that when information (random code) is identical, HDMI outfan determines HDMI output resolution ratio handover success, protects
Holding and exported by described new resolution, HDMI outfan uses new resolution to send signal to HDMI receiving terminal.
Step 208: exit switching resolution operation.
When judge make new advances resolution identical with current resolution time, the resolution before switching and switch after resolution phase
With, it is not necessary to switching over resolution operation, HDMI outfan exits switching resolution operation.
Such as: 1080P resolution do not supported by television set, the currently displaying resolution of television set is 720P, now user to
Set Top Box sends the operational order of switching resolution, it is desirable to being switched to 1080P resolution, Set Top Box judges 1080P resolution
Different from 720P resolution, preserve 720P resolution, be switched to 1080P resolution, send to television set under 1080P resolution
Comprise the checking dialog box information of switching checking information, do not support 1080P resolution due to television set, so television set cannot show
Showing that this comprises the checking dialog box information of switching checking information, therefore user cannot know that the switching checking information needing input is
What, it is impossible to inputting correct switching checking information, Set Top Box was not received by switching checking letter at 5 seconds in (preset time)
Breath, assert that television set cannot support 1080P resolution, auto-returned 720P resolution, continues under 720P resolution to TV
Machine sends signal, and television set can recover again normally to show, user can continue to watch program.Set Top Box is also sent out to television set
Send prompting television set not support the information of 1080P resolution, make user learn the reason that cannot switch resolution.
In sum, in the embodiment of the present invention, HDMI outfan, after receiving switching resolution operation instruction, first judges
The new resolution needing switching is the most identical with current resolution, just switches in the case of differing；Only preset
When receiving the correct switching checking information of user's input in duration, just can determine that resolution handover success, otherwise returning ought
