Abstract
The invention provides an exceptional-signal backup display system and the method thereof; the exceptional-signal backup display system includes a transmission unit used for acquiring an image signal, a backup display unit provided with the backup image information, an exception detection unit used for detecting the image signal and outputting a switching signal when the image signal is detected to be exceptional, and a playing unit used for acquiring and playing the image signal from the transmission unit in the normal operating state; when the exception detection unit outputs a switching signal, the playing of the image signal from the transmission unit is stopped; meanwhile, the image signal is played by the backup image information of the backup display unit.
Description
Technical field
What the present invention relates to is a kind of backup display system and method thereof, especially a kind of backup display system and method thereof of playing another image information of switching when former image signal is unusual.
Background technology
Existing display system is when the playing video signal; adopt mostly and directly obtain the broadcast format that image signal then is converted to a broadcast unit and play so that described broadcast unit to be provided; occur as surging and work as the obtained signal of display system; noise; can't understand mess code or signal content when playing signal abnormality such as complete black or complete white picture; only can treat that the people solves above-mentioned signal abnormal problem for realizing the back; yet signal occur to unusually fully solve during; broadcast unit can't normal play; and make the audience feel lofty or uncomfortable visual experience; or there is the artificial mode of utilization that broadcast unit is switched other signal of broadcast; but signal occur to unusually artificial switching during still can't make the broadcast unit can't normal play and make the audience feel lofty or uncomfortable visual experience, so how to solve the big problem that above-mentioned signal negative effect audience's when unusual problem has done one's utmost to overcome for relevant dealer.
Summary of the invention
Fundamental purpose of the present invention is to play signal and occurs when unusual, makes broadcast unit automatically switch and plays default redundant image information to avoid the making audience be subjected to negative effect.
For reaching above-mentioned purpose, the invention provides the unusual backup display system of a kind of signal, include: a transmission unit, it obtains an image signal; One redundant display unit, it has a redundant image information; One abnormity detecting unit, it detects described image signal and output one switching signal when abnormality appears in the described image signal of differentiation; One broadcast unit, described broadcast unit obtains and plays the image signal of described transmission unit when normality, and when exporting described switching signal in described abnormity detecting unit, then stop to play the image signal of described transmission unit, and change by the redundant image information of described redundant display unit and replace broadcast.
In addition, the present invention provides a kind of signal unusual redundant display packing in addition, includes: a normality is play step, and it uses a broadcast unit to play an image signal; One detecting step, whether it detects described image signal unusual to differentiate described image signal; All are changed step suddenly, and it is then replaced described image signal and play described broadcast unit is described with a redundant image information after the described image signal of differentiation is unusual.

Description of reference numerals: 1-transmission unit; 2-redundant display unit; 3-abnormity detecting unit; The 4-broadcast unit.
Embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the present invention is above-mentioned.
See also shown in Figure 1ly, it is the configuration diagram of a preferred embodiment of the present invention.The invention provides the unusual backup display system of a kind of signal, include:
One transmission unit 1, it obtains an image signal;
One redundant display unit 2, it has a redundant image information;
One abnormity detecting unit 3, it detects described image signal and output one switching signal when abnormality appears in the described image signal of differentiation, described abnormity detecting unit 3 can be the waveform detection device, noise detector or image analyzer, described waveform detection device exceeds a preset range at the waveform of detecting described image signal and assert that then abnormality appears in described image signal, described noise detector exceeds a preset range in the noise tolerance value of detecting described image signal and assert that then abnormality appears in described image signal, and described image analyzer assert then that for the mess code that can't understand abnormality appears in described image signal at the contents of the described image signal of detecting;
One broadcast unit 4, described broadcast unit 4 obtains and plays the image signal of described transmission unit 1 when normality, and in described abnormity detecting unit during the described switching signal of 3 outputs, then stop to play the image signal of described transmission unit 1, and change by the redundant image information of described redundant display unit 2 and replace broadcast, wherein said broadcast unit 4 has plural number at same picture and shows block, and selects to be play by described image signal and described redundant image information one in the single display block.
The person of noting, in the present embodiment, described broadcast unit 4 is obtained described image signal and described redundant image information simultaneously and is allowed the one of described image signal and described redundant image information play by shielding mode, in right real the work, described broadcast unit 4 also can use the mode that only obtains described image signal under the normality and play to the described redundant image information of described redundant display unit 2 taking-ups again after receiving described switching signal.
See also shown in Figure 2ly, it is for the schematic flow sheet of another preferred embodiment of the present invention.In addition, the present invention provides a kind of signal unusual redundant display packing in addition, includes:
One normality is play step S1, and it uses above-mentioned broadcast unit 4 to play an image signal;
One detecting step S2, whether it detects described image signal unusual to differentiate described image signal, and whether wherein said detecting step utilization wave form analysis, noise tolerance analysis or image analysing computer be unusual to differentiate described image signal;
All rapid S3 that change step, it is after the described image signal of differentiation is unusual, then described image signal is replaced with a redundant image information described broadcast unit 4 described broadcasts, broadcast unit 4 described in the described switch step can adopt and stop to play described image signal earlier, change the mode of playing described redundant image information again into, or adopt described broadcast unit 4 to accept described redundant image information and described image signal simultaneously, and in described normality broadcast step, shield described redundant image information, in described switch step, then shield described image signal.
In sum, because unusual backup display system and the method thereof of signal of the present invention, differentiating originally after the image signal that broadcast unit 4 is play is unusual, automatically switch immediately and play the redundant image information, so puzzlement of negative effect audience in the time of avoiding existing signal unusual, therefore the present invention has progressive and meets the important document of applying for patent of invention, files an application in accordance with the law.
Below the present invention is described in detail, only the above person only is a preferred embodiment of the present invention, when not limiting scope of the invention process.Be that all equalizations of doing according to the present patent application scope change and modify etc., all should still belong in the patent covering scope of the present invention.
