Embodiment 1

[0028] like figure 1 Shown is a schematic structural diagram of Embodiment 1 of the distributed digital processing system of the present invention.

[0029] As shown in the figure, the distributed processing system of the present invention includes a control unit connected to a signal source (not shown in the figure), a computing unit connected to the control unit, and two computing units connected to the signal source and the computing unit respectively. One or more than two processing units, and at least two switching units, any switching unit is correspondingly connected to one of the display units in the high-resolution display environment, wherein the control unit, computing unit, and processing unit execute The specific functions can be as described in the distributed digital processing system with the application number 200810028534.X, and will not be repeated here.

[0030] Wherein, in this embodiment, any processing unit includes two output terminals, and one of them...

Embodiment 2

[0041] like figure 2 Shown is a schematic structural diagram of Embodiment 2 of the distributed digital processing system of the present invention. In this embodiment, the difference from the above-mentioned Embodiment 1 is that this embodiment also includes switching units connected to each switching unit. A control unit, each switching unit controls the connection between the first output end and the second output end of the processing unit in the processing unit group and the backup processing unit and the switching unit according to the control signal of the switching control unit.

[0042] In the distributed digital processing system of this embodiment, in the normal processing state, the specific processing operation process can be the same as that in the first embodiment above. The switching unit sends a control signal, and the switching unit performs switching according to the control signal of the switching control unit. The specific switching method can be the same ...

Embodiment 3

[0046] like image 3 As shown, it is a schematic structural diagram of the third embodiment of the distributed digital processing system of the present invention. In this embodiment, the difference from the above-mentioned embodiment two is that the switching control unit in this embodiment is also related to the control unit is connected.

[0047] In the distributed digital processing system of this embodiment, the specific processing operation mode in the normal processing state and the switching mode in the case of a failure of the processing unit may be the same as that in the second embodiment above, or may be Use other methods.

[0048] Taking a processing unit group of the distributed digital processing system in this embodiment as an example, in one of the processing methods, the specific processing operation flow may also be:

[0049] In the normal processing state, the processing unit in the processing unit group only processes the corresponding signal of the displ...

Abstract

The invention discloses a distributing-type digit processing system comprising a control unit, a calculation unit, at least one processing unit group and at least one switching unit, wherein, the control unit and the calculation unit are connected with a signal source in order, the processing unit group is connected with the calculation unit, and any one switching unit is connected with at least one processing unit; each processing unit group comprises at least one processing unit and at least one back-up processing unit; each switching unit is respectively connected with at least one display unit in high resolution display environment so as to switch the connection relation of the processing unit, the back-up processing unit and the display unit in the corresponding processing unit group. The invention adds at least one switching unit and adds at least one back-up processing unit for the processing unit in the processing unit group; when the processing unit goes wrong, the back-up processing unit processes the content processed by the faulted processing unit and outputs to the display unit by the switching unit, thus not affecting the normal work of the distributing-type processing system but improving the reliability of the distributing-type processing system.

Description

technical field [0001] The invention relates to the technology of distributed processing signal, in particular to a distributed digital processing system. Background technique [0002] In the existing ultra-high-resolution display environment using multiple display output channels, when processing digital signals, one processing device is usually connected to multiple display devices, and the information processed by the processing device is sent to When the display device performs display and the processing device performs processing, one way is to decode through software decoding, that is, to use the CPU to complete the decoding work. However, for a single processing device, it can only process limited digital signals, such as 8 In this case, for a high-resolution display environment that can display dozens of channels, only processing 8 channels of digital video is far from meeting the needs of users. Another way is to use Dedicated hardware boards are used for decoding ...
