The controlling circuit 25 then obtains, for example, the predetermined image information to be displayed in the displaying unit 5 among the plurality of pieces of image information stored in the nonvolatile memory 26 on the basis of the set identification information.
It is a matter of course that the number of the plurality of external terminals 25a for the identification information is not limited to the two, but that the number is arbitrary as long as the number makes it possible to identify each of the plurality of pieces of image information stored in the nonvolatile memory 26.
The nonvolatile memory 26 is, for example, a recording medium against which the reading, the writing, and the erasing of data can be performed.
To put it concretely, the nonvolatile memory 26 previously stores, for example, a plurality of pieces of image information to be displayed in the displaying unit 5.
Moreover, the nonvolatile memory 26 stores, for example, the logo information pertaining to the video information displayed in the displaying unit 5 by the first display controlling unit 3 when the power source of the video outputting apparatus 1 is turned off, in accordance with a control signal input from the controlling unit 8.
The first display controlling unit 3, as a first display controlling section, allows the displaying unit 5 to display, for example, the video information input from the tuner apparatus E through the signal processing section (not shown) in accordance with a control signal input from the controlling unit 8.
To put it concretely, the first display controlling unit 3 performs, for example, predetermined processing to the vide information input from the tuner apparatus E, and outputs the processed video information to the output switching unit 4.
The output switching unit 4 switches, for example, the information to be output to the displaying unit 5 to the predetermined image information and the logo information, which are input from the controlling circuit 25 and to the video information, which is input from the first display controlling unit 3, on the basis of the switching information stored in the register 4a.
The register 4a stores, for example, the switching information to allow the output switching unit 4 to switch the information to be output to the displaying unit 5 to the predetermined image information and the logo information, which are input from the controlling circuit 25, and to the video information, which is input from the first display controlling unit 3, on the basis of the control signal input from the controlling unit 8.
That is, the switching information includes the switching information for switching the information to be output to the displaying unit 5 to the predetermined image information and the logo information, which are input from the controlling circuit 25, and the switching information for switching the information to be output to the displaying unit 5 to the video information, which is input from the first display controlling unit 3.
The displaying unit 5 is, for example, liquid crystal display equipment, and, as a displaying section, outputs, for example, an image based on the image information and the logo information, which are input from the output switching unit 4, and the video based on the video information, which is input from the output switching unit 4.
The power source unit 6 is composed of, for example, a storage battery, and performs power distribution to each section of the video outputting apparatus 1 when the power source of the video outputting apparatus 1 is turned on.
The operating unit 7 is compose of, for example, operation buttons (not shown) provided on the external surface of the video outputting apparatus 1, a remote controller (not shown) for the video outputting apparatus 1, and a remote control receiving section (not shown) capable of communicating with the remote controller.

The controlling unit 8 is composed of, for example, a central processing unit (CPU) 81, a random access memory (RAM) 82, and a storing unit 83, as shown in
The CPU 81 performs, for example, various controlling operations in accordance with various processing programs for the video outputting apparatus 1, which programs are stored in the storing unit 83.
The RAM 82 includes, for example, a program storing region to expand the processing program to be executed by the CPU 81, a data storing region to store input data and processing results produced at the time of the execution of the processing program, and the like.
The storing unit 83 stores, for example, a system program capable of being executed in the video outputting apparatus 1, various processing programs capable of being executed on the system program, the data to be used at the time of the execution of these various processing programs, and the data of the processing results of the operation processing of the CPU 81. Incidentally, the programs are stored in the storing unit 83 in the forms of program codes that a computer can read.
To put it concretely, the storing unit 83 stores, for example, an video display controlling program 83a, a judging program 83b, a switching information storage controlling program 83c, and a logo information storage controlling program 83d, as shown in
The video display controlling program 83a enables the CPU 81 to realize, for example, the function of inputting a control signal into the first display controlling unit 3 to allow the displaying unit 5 to display the video information input from the tuner apparatus E.
The judging program 83b enables the CPU 81 to realize, for example, the function of judging whether video information is in the state capable of being displayed in the displaying unit 5 by the first display controlling unit 3 or not.
The switching information storage controlling program 83c enables the CPU 81 to realize, for example, the function of allowing the register 4a to store switching information.
To put it concretely, for example, if the CPU 81, which has executed the judging program 83b, judges that video information is in the state capable of being displayed in the displaying unit 5 by the first display controlling unit 3, then the CPU 81 allows the register 4a to store the switching information for switching the information to be output to the displaying unit 5 to the video information to be input from the first display controlling unit 3.
Moreover, for example, if the CPU 81 is instructed to turn off the power source of the video outputting apparatus 1 by a user's operation of the operating unit 7, then the CPU 81 allows the register 4a to store the switching information for switching the information be output to the displaying unit 5 to the predetermined image information and the logo information, which are input from the controlling circuit 25.
Thereby, if the power source of the video outputting apparatus 1 is turned on after the turning-off of the power source of the video outputting apparatus 1, then the predetermined image information and the logo information, which have been stored in the nonvolatile memory 26, are led to be displayed in the displaying unit 5 during a period from the time when the power source of the video outputting apparatus 1 is turned on to the time when video information is displayed in the displaying unit 5 by the first display controlling unit 3.
The logo information storage controlling program 83d enables CPU 81 to realize, for example, the function of updating the logo information stored in the nonvolatile memory 26 by allowing the nonvolatile memory 26 to store the logo information pertaining to the video information displayed in the displaying unit 5 by the first display controlling unit 3 when the power source of the video outputting apparatus 1 is turned off.
The CPU 81 functions as a storage controlling section by executing this logo information storage controlling program 83d.
The mounting method of the controlling circuit 25 into the video outputting apparatus 1 is described with reference to the flowchart of
Input setting is first performed to the plurality of external terminals 25a in order to set display setting information (Step S11).
The controlling circuit 25 is next mounted onto the substrate (not shown) of the video outputting apparatus 1 (Step S12).
That is, after the input setting has been performed to the plurality of external terminals 25a and desired display setting information has been set, the controlling circuit 25 is mounted into the video outputting apparatus 1.
The processing pertaining to the outputting of the predetermined image information and the video information by the video outputting apparatus 1 is described with reference to the flowchart of
When a user first operates the operating unit 7 to instruct to turn on the power source of the video outputting apparatus 1 (Step S21), the power source unit 6 starts the power distribution to each section of the video outputting apparatus 1 (Step S22).
The crystal oscillator 21 next oscillates in association with the start of the power distribution at Step S22, and consequently the predetermined image information and the logo information stored in the nonvolatile memory 26 is displayed in the displaying unit 5 (Step S23).
Next, until the start-up of the CPU 81, which controls the whole video outputting apparatus 1, has been completed, the processing at Step S24 is repeatedly performed.
Next, when the start-up of the CPU 81 is completed (Step S24; Yes), the CPU 81 executes the judging program 83b to judge whether video information is in the state capable of being displayed in the displaying section 5 by the first display controlling unit 3 or not (Step S25).
If the CPU 81 judges that the video information is not in the state capable of being displayed in the displaying unit 5 by the first display controlling unit 3 yet at Step S25 (Step S25; No), then the CPU 81 repeatedly performs the processing at Step S25.
On the other hand, if the CPU 81 judges that the video information is in the state capable of being displayed in the displaying unit 5 by the first display controlling unit 3 at Step S25 (Step S25; Yes), then the CPU 81 executes the switching information storage controlling program 83c to allow the register 4a to store the switching information for switching the information to be output to the displaying unit 5 to the video information to be input from the first display controlling unit 3, and to allow the output switching unit 4 to switch the information to be output to the displaying unit 5 to the video information to be input from the first display controlling unit 3 (Step S26).
The CPU 81 next judges whether the user has operated the operating unit 7 to instruct to turn off the power source of the video outputting apparatus 1 or not (Step S27).
If the CPU 81 judges that the turning-off of the power source of the video outputting apparatus 1 has not been instructed at Step S27 (Step S27; No), then the CPU 81 repeatedly performs the processing at Step S27.
On the other hand, if the CPU 81 judges that the turning-off the power source of the video outputting apparatus 1 has been instructed at Step S27 (Step S27; Yes), then the CPU 81 executes the logo information storage controlling program 83d to allow the first display controlling unit 3 to store the logo information pertaining to the video information displayed in the displaying unit 5 into the nonvolatile memory 26 (Step S28).
The CPU 81 next executes the switching information storage controlling program 83c to allow the register 4a to store the switching information for switching the information to be output to the displaying unit 5 to the predetermined image information and the logo information, which are input from the controlling circuit 25, and allows the output switching unit 4 to switch the information to be output to the displaying unit 5 to the predetermined image information and the logo information, which are input from the controlling circuit 25 (Step S29). Then, the CPU 81 allows the power source unit 6 to end the power distribution to each section of the video outputting apparatus 1 (Step S30), and ends the present processing.
According to the video outputting apparatus 1 of the present invention described above, video information can be displayed in the displaying unit 5 by the first display controlling unit 3, and the predetermined image information can be displayed in the displaying unit 5 during the period from the time when the power source of the video outputting apparatus 1 is turned on to the time when the video information is displayed in the displaying unit 5 by the first display controlling unit 3, by the second display controlling unit 2. To put it concretely, the second display controlling unit 2 is provided with the crystal oscillator 21 and the PLL circuit 22 to generate the reference clock signal when the power source of the video outputting apparatus 1 is turned on, the nonvolatile memory 26 to store the predetermined image information, and the controlling circuit 25 to include the plurality of external terminals 25a for setting the display setting information pertaining to the display settings of the displaying unit 5, and the controlling circuit 25 can allow the displaying unit 5 to display the predetermined image information stored in the nonvolatile memory 26 on the basis of the display setting information set by the plurality of external terminals 25a in accordance with the reference clock signal generated by the crystal oscillator 21 and the PLL circuit 22.
Consequently, the controlling circuit 25 provided in the second display controlling unit 2 can allow the displaying unit 5 to display the previously stored predetermined image information on the basis of the previously set display setting information in accordance with the reference clock signal, which is generated when the power source of the video outputting apparatus 1 is turned on, even if the start-up of the CPU 81, which controls the whole video outputting apparatus 1, is not completed yet. That is, the controlling circuit 25 can allow the displaying unit 5 to display the predetermined image information during the period form the time immediately after the turning-on of the power source of the video outputting apparatus 1 to the time when the video information is displayed.
Moreover, because the display setting information is set by the combination of setting of the plurality of external terminals 25a connected to the substrate (not shown) of the video outputting apparatus 1, the controlling circuit 25 can deal with various displaying sections 5 having different display settings from one another.
Moreover, according to the video outputting apparatus 1, the display setting information includes the resolution information pertaining to the horizontal resolution and the vertical resolution of the displaying screen of the displaying unit 5; the second display controlling unit 2 is provided with the horizontal counter 23, which counts the number of horizontal pixels in accordance with the reference clock signal generated by the crystal oscillator 21 and the PLL circuit 22 and is reset when the counted value reaches the value of the horizontal resolution included in the resolution information, and the vertical counter 24, which counts the number of vertical pixels each time the horizontal counter 23 is reset and is reset when the counted value reaches the value of the vertical resolution included in the resolution information; and the controlling circuit 25 obtains the predetermined image information by one pixel at a time from the nonvolatile memory 26 in synchronization with the horizontal counter 23, and can allow the displaying unit 5 to refresh displaying the obtained predetermined image information each time the vertical counter 24 is reset.
Consequently, the controlling circuit 25 can deal with various displaying sections 5 having different resolution of the display screens from one another by itself, and can display the predetermined image information suitable for the displaying screens of the displaying sections 5 even if the CPU 81, which controls the whole video outputting apparatus 1, does not set the resolution of the displaying screen of the displaying sections 5.
Moreover, according to the video outputting apparatus 1, the display setting information includes the image position information pertaining to the position in the displaying screen of the displaying unit 5 where the predetermined image information is displayed, and the controlling circuit 25 can obtain the predetermined image information from the nonvolatile memory 26 at the obtaining timing based on the image position information.
Consequently, the controlling circuit 25 can deal with various demands for displaying the predetermined image information at desired positions in the displaying screens by itself, and the controlling section 25 can allow the displaying sections 5 to display the predetermined image information at the desired positions in the displaying screens of the displaying sections 5 even if the CPU 81, which controls the whole video outputting apparatus 1, does not set the positions in the displaying screens of the displaying sections 5 whereas the predetermined image information is displayed.
Moreover, according to the video outputting apparatus 1, the nonvolatile memory 26 stores the plurality of pieces of image information, and the display setting information includes the identification information for identifying the predetermined image information to be displayed in the displaying unit 5 among the plurality of pieces of image information stored in the nonvolatile memory 26; and the controlling circuit 25 can obtain the predetermined image information to be displayed in the displaying unit 5 among the plurality of pieces of image information stored in the nonvolatile memory 26 on the basis of the identification information.
Consequently, the controlling circuit 25 can deal with various demands for allowing the image information to be displayed the desired predetermined image information by itself, and the controlling section 25 can display the desired predetermined image information even if the CPU 81, which controls the whole video outputting apparatus 1, does not set the predetermined image information to be displayed.
