Below only be a kind of example of counting mode of the number of times of output format switching command, also can select other technical approach for use, for example, initial time n=1 is n=n+2 with the frequency n counting when receiving the output format switching command at every turn, etc.
In addition, in the method for the embodiment of the invention, after frequency n equals the quantity of alternative output format and selects the output format of described frequency n correspondence, with described frequency n zero clearing.
Need to prove that in the method for the embodiment of the invention, this output format switching command is voice signal, touching signals or by pressing the signal of at least one button input.For example, this output format switching command is by pressing the signal of at least two buttons inputs.
As shown in Figure 2, the embodiment of the invention also provides a kind of digital video converting means 200, and this device comprises:
The device of the embodiment of the invention can be selected the output format of digital video signal to be converted according to the number of times that receives the output format switching command, initiatively and fast select best output format, can realize the adaptive of digital video converting means (for example, set-top box) and its receiving terminal (television set).
In addition, the device of the embodiment of the invention also can comprise:
The device of the embodiment of the invention carries out in the digital video conversion process, can determine whether carrying out the switching of output format according to the output display effect of the signal after the conversion, and at initial time, the output format that can give tacit consent to is changed.Tool is sayed it, shown in identification module 201 can further comprise:
Adaptation unit 2012 is used for described frequency n being designated as n=n+1, and selecting the output format of described frequency n correspondence when receiving described order.
Below only be a kind of example of counting mode of the number of times of output format switching command, also can select other technical approach for use, for example, initial time n=1 is n=n+2 with the frequency n counting when receiving the output format switching command at every turn, etc.
The device of the embodiment of the invention also can comprise:
The device of the embodiment of the invention also can comprise:
Need to prove that in the device of the embodiment of the invention, this output format switching command is voice signal, touching signals, by in the signal of pressing at least one button input one or more.For example, this output format switching command is by pressing the signal of at least two buttons inputs.
When this output format switching command was voice signal, control module 204 can comprise: the audio frequency receiving element, for the output format switching command that receives the voice signal form; When this output format switching command was touching signals, control module 204 can comprise: touch unit (for example, touch-screen), for the output format switching command that receives the touching signals form; When this output format switching command for when pressing the signal of at least one button input, control module 204 can comprise: button is used for receiving by pressing the described output format switching command of at least one described button input.Control module 204 also can have the unit of above-mentioned any one or this output format switching command of multiple reception simultaneously, and also namely this output format switching command also can be the combination of any kind in the above-mentioned various signal form.
Be digital video transform method and the device that example further specifies the embodiment of the invention below with the set-top box, the remote controller of this set-top box is the control module of this digital video converting means, and except each part of the digital video converting means of the embodiment of the invention, this set-top box and have other requisite part well-known to those skilled in the art, for example, input connecting interface with digital signal, the interface that is connected with digital signal receiving terminal (television set), control button etc.The inner predefine N(N of this set-top box is preferably more than and equals 2 natural number) plant the HDMI output format as alternative output format, also i.e. this set-top box and the adaptive alternative output format of HDTV (High-Definition Television) that is mated, the number of times that counter n(0≤n≤N) is used for record output format switching command is set in set-top box inside, each time behind the set-top box electrification reset (set-top box is opened at every turn), with this counter O reset, i.e. n=0.
Whether user's output of checking machine top box on TV normally shows, if it is undesired, can change the output format of set-top box by remote controller input/output format switching command, set-top box is selected corresponding output format according to the number of times of the output format switching command that receives from alternative output format, carry out the conversion of digital signal and export corresponding HDMI signal according to it, in this manner, the user constantly attempts various predefined alternate formats, normally shows on TV up to set-top box signal.Detailed process is as shown in Figure 3:
S301. set-top box and set-top box remote controller initialization.Tool is sayed it, when opening set-top box, is the output format of acquiescence with the corresponding output format of n=0.
Whether the demonstration that S302. detects TV is normal, if show that normally then the user does not carry out the input of output format switching command, carries out the conversion of digital signal according to existing output format, otherwise, execution in step S303.
S303. by remote controller input/output format switching command.
Preferably, in the set-top box of the embodiment of the invention, can be provided for the independent button that output format is switched on its remote controller, the user whenever presses once (or in setting-up time continuous several times) this button and just imports the output format switching command one time.But, consider more and more miniaturization of present set-top box and remote controller, integrated, the trend that button resources on the remote controller is very limited, the set-top box of the embodiment of the invention more preferably, exporting specific key assignments when any two or two selected buttons on its remote controller are pressed at the same time comes the announcement machine top box to switch output format, also be, in this step, the user is to press the mode input/output format switching command of Macintosh, thereby do not increase cost and the volume of set-top box remote controller, and have simple operation, develop simple advantage.
S304. remote controller sends key assignments to set-top box.
S305. set-top box receives the key assignments that remote controller sends, and the counting of the counter in the set-top box is added 1, namely makes n=n+1, and according to the HDMI output format of current n correspondence to TV output HDMI signal.
S306. judge whether current n equals N, if equal N, with the n zero clearing, i.e. n=0, and return execution in step S302, otherwise, direct execution in step S302.
To sum up, when the user finds that the output of set-top box can't normally show on TV, press the set-top box remote controller combination button simultaneously, set-top box is after receiving the special key assignments of combination button, to select a kind of alternative output format, and according to this form output HDMI signal.The problem of incorrect, the indeterminate or display format that disappearance can't adaptive TV be supported of TV HDMI EDID information to such an extent as to the set-top box of the embodiment of the invention can effectively solve, can utilize simultaneously the hardware device of existing remote controller, saved cost and the volume of set-top box remote controller, and had simple operation, develop simple advantage.
