At first, demodulation section 502 demodulation are by the audio signal of optical cable from the data packet form as shown in Figure 7 of broadcast transmission module 100 receptions.Dispenser will be distributed to 8 audio frequency acceptance divisions 506 by the audio signal of demodulation section 502 demodulation.Here, dispenser 504 is with reference to the packet of audio signal shown in Figure 7, and IP address or distinguished symbol by audio output part 506 distribute audio signals to the audio output part 506 of unanimity.Audio output part 506 with the audio signal Out1, the Out2 that receive ..., Out7, Out8 output to the outside by loud speaker etc.
Below, with reference to Fig. 9 to Figure 15 the 2nd embodiment that transmits vision signal is described, at first the method that the Frequency mixing processing vision signal transmits is described by Fig. 9 to Figure 12.
Fig. 9 is the figure of expression according to the formation of the broadcast transmission module of the 2nd embodiment of the present invention.
As shown in Figure 9, according to the broadcast transmission module 100 of the 2nd embodiment of the present invention is as the module of house broadcasting usefulness, comprising: video input part 101b, the 102b of video modulation portion, prolong chi portion 104, Frequency mixing processing portion 105, user interface 107, display part 108 and video efferent 109b.In an embodiment of the present invention, for convenience of explanation, 4 vision signals of illustration input and export 1 vision signal and illustrate by mixing.
Frequency mixing processing portion 105 is made of central processing unit, and possesses the Frequency mixing processing algorithm software.Frequency mixing processing portion 105 has the function of exporting its result by the vision signal of Frequency mixing processing algorithm Frequency mixing processing digital form afterwards.The Frequency mixing processing algorithm carries out Frequency mixing processing and is presented at a picture a plurality of vision signals of being selected by the user.In addition, mix audio signal according to the size of volume corresponding to selecteed vision signal.A plurality of vision signals that Frequency mixing processing portion 105 receives by 103 outputs of delay portion dispose a plurality of pictures according to the pattern that is set on a picture.The vision signal of the data packet form that so generates is passed to video efferent 109b.
Below select to want the method for the vision signal of mixing to describe by Figure 10 a and Figure 10 b to the user.Selection picture shown in Figure 10 a and Figure 10 b is by display part 108 picture displayed.Figure 10 a is the illustration figure according to the selection picture that is used for mixed video signal of the 2nd embodiment of the present invention.
Shown in Figure 10 a, be provided with the parent menu selection portion 350 that to select parent menu in the left-hand end of selecting picture.Can show a plurality of parent menu projects by row in parent menu selection portion 350.The parent menu project can show corresponding function by icon or the literal that the user can intuitively confirm.That is, reach " alarm of fire " corresponding respectively user interface and can one be listed as the left-hand end that is configured in picture with " audio mixer " that be equivalent to the parent menu project, " video mixer ", " directly broadcasting ", " reservation broadcasting ", " activity music ", " player ", " environment set ".
If in the parent menu that parent menu selection portion 350 shows, select " video mixer ", then regulate window 360 and mixing control part 370, in the lower end display mode selection portion 380 of selecting picture in central authorities' demonstration volume of selecting picture.
Regulate window 360 at audio frequency and show that the volume that can regulate the volume of 4 vision signal In21, In22 being transfused to, In23, In24 regulates bar.The user moves up and down volume by mouse or keyboard and regulates bar, thereby can regulate the volume corresponding with the vision signal that is transfused to.
The user can select to want 2 vision signals of mixing by mixing control part 370 in 4 vision signal In21, In22, In23, In24, set the mixing ratio of selecteed vision signal.
Mode selection part 380 is presented at the lower end of selecting picture, shows the multiple picture configure icons of the picture configuration that can select 2 vision signals at mode selection part 380.Therefore, the user can utilize the picture configuration mode that mode selection part 380 is selected selecteed vision signal.For convenience of explanation, will be made as " the 1st image ", will be called " the 2nd image " with the part that black is represented in the part that mode selection part 380 is represented with white.The 1st image and the 2nd image are 2 images selecting in 4 vision signal In21, In22, In23, In24.
Figure 10 b is the figure that represents briefly according to the mixing control part of Figure 10 a.Shown in Figure 10 b, be provided with mixing in the central authorities of mixing control part 370 and regulate bar 372, regulating bar 372 with mixing is the center, in left side and right side the 1st selection portion 374 and the 2nd selection portion 376 is set respectively.In addition, be provided with upwards button 377, be provided with to knob down 378 in the lower end of the 2nd selection portion 376 in the upper end of the 1st selection portion 374.
The user selects to want 2 vision signals of mixing by the 1st selection portion 374 and the 2nd selection portion 376.And, regulate the mixing ratio of vision signal while the user can move up and down mixing adjusting bar 372.Here, can move up and down mixing by mouse and regulate bar 372, can and move mixing to knob down 378 and regulate bar 372 by knob 377 upwards.That is, if click the button 377 that makes progress, then mixing is regulated bar to moving up automatically till the click again, similarly, clicks to knob down 378, and then mixing is regulated bar to moving down automatically till the click again.
When mixing adjusting bar 372 moved up, 1st image corresponding with the vision signal of being selected by the 1st selection portion 374 was exaggerated, and 2nd image corresponding with the vision signal of being selected by the 2nd selection portion is reduced.Similarly, when mixing adjusting bar 372 moved down, the 1st image was reduced, and the 2nd image is exaggerated.In this way, the user is presented at the picture configuration of the 1st image and the 2nd image of mode selection part 380 by 370 selections of mixing control part.
Below, with reference to the frequency mixing method of Figure 11 explanation according to the vision signal of the 2nd embodiment of the present invention.Figure 11 is the precedence diagram of expression according to the frequency mixing method of the vision signal of the 2nd embodiment of the present invention.
At first, when in a plurality of vision signal of broadcast transmission module 100 inputs (S1110), the user is by a plurality of vision signals of selection picture and selecting as Figure 10 a.
That is, show as during the selection picture of Figure 10 a (S1120), the user wants 2 vision signals of mixing by the 1st selection portion 374 and 376 selections of the 2nd selection portion in 4 input signal In1, In2, In3, In4 at the display part 108 of broadcast transmission module 100.
And the user selects the 1st image selected respectively by the 1st selection portion 374 and the 2nd selection portion 376 and the picture configuration mode (S1140) of the 2nd image by mode selection part 380.
And, regulate the mixing ratio (S1150) of vision signal while the user can move up and down mixing adjusting bar 372.Here, when the user moved up mixing adjusting bar 372, the 1st image shown in Figure 10 a was exaggerated, and when moving down mixing adjusting bar 372, the 1st image is reduced.
Like this, according to the 2nd embodiment of the present invention, broadcast transmission module 100 is mixed the vision signal that is transfused to the software formula, thereby further improves the quality of vision signal, can further simplify the formation of broadcast transmission module 100.
Figure 12 is the figure of expression according to the formation of the broadcast reception module of the 2nd embodiment of the present invention.
