[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a method for repairing a zero bitstream anomaly according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0027] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for repairing zero code stream anomalies in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0028] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0029] In this embodiment, a method for repairing zero bitstream anomaly running on the above mobile terminal is provided. Figure 2 is a flowchart of a method for repairing a zero bitstream anomaly according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0030] Step S202, when a zero bitstream exception occurs in a target device, determining the exception type of the zero bitstream exception according to whether the target application can obtain a target bitstream from the target device;

[0031] The target device may be a video recorder (DVR). Figure 3 The system architecture diagram shown in Figure 2 is shown in Figure 2.

[0032] The front-end analog camera is connected to the DVR device through the coaxial cable. The video data is collected by the analog camera and transmitted to the AD chip (target chip) of the DVR device through the coaxial cable. The AD chip performs digital-to-analog conversion and protocol analysis, and then converts the analog signal into BT656, BT1120 or MIPI signal, and finally transmits the converted signal to the main control end. After the main control end receives the signal, the DVR previews the video data and encodes and saves it to disk.

[0033] Zero bitstream anomalies can be divided into the following three types:

[0034] The first abnormal type is that the target application obtains the target code stream from the master control terminal, and the target code stream is not stored in the hard disk;

[0035] The second abnormality type is that the target application cannot obtain the target code stream from the master terminal, and the display screen of the target device shows an abnormal picture of the target code stream, such as distortion;

[0036] The third abnormal type is that the target application cannot obtain the target code stream from the main control end, and the display screen of the target device normally displays the screen of the target code stream.

[0037] As an optional implementation, the type of the zero bitstream exception may be determined in the following manner:

[0038] In the case that the target application cannot obtain the target code stream from the main control terminal of the target device, determining the exception type of the zero code stream exception according to the display screen of the target device;

[0039] Specifically, when the target application obtains the target code stream from the main control end and the target code stream is not stored in the hard disk, the zero code stream exception is determined as the first exception type.

[0040] When the target application cannot obtain the target code stream from the master control end, and the display screen of the target device displays the target code stream abnormally, the zero code stream abnormality is determined as the second abnormality type.

[0041] When the target application cannot obtain the target code stream from the master control end, and the display screen of the target device normally displays the screen of the target code stream, the zero code stream exception is determined as a third exception type.

[0042] In the above embodiment, the target application can detect the type of zero bitstream anomaly of the target device, actively trigger the self-detection program of the target device, and complete the zero bitstream self-repair process. Compared with the manual investigation of the cause of the zero bitstream anomaly of the target device in the prior art, this embodiment can achieve the technical effect of reducing time consumption and improving efficiency.

[0043] Step S204, determining the reason why the zero bitstream exception occurs in the target device according to the exception type;

[0044] like Figure 4 The figure is a schematic diagram of the overall process according to an embodiment of the present invention, which includes:

[0045] In the case of the first abnormality type, it is determined that the cause of the zero bitstream abnormality is the hard disk abnormality; after excluding the abnormalities of the AD chip and the main control end, a prompt message can be output, such as a pop-up prompt on the interface, to prompt the user that the hard disk is abnormal and it is recommended to replace the hard disk. After replacing the hard disk, check whether the target bitstream is stored in the replaced hard disk to confirm whether the zero bitstream abnormality is resolved.

[0046] In the case of the second abnormality type, determining that the cause of the zero code stream abnormality is that the target chip is abnormal, or the main control terminal is abnormal, or the target analog camera is abnormal, or the coaxial cable between the target analog camera and the target device is abnormal;

[0047] Specifically, in the case of the second abnormal type, a reset operation is performed on a target acquisition channel and a target output channel of the target chip, wherein the target chip includes a plurality of acquisition channels and a plurality of output channels, the acquisition channels and the output channels allow free binding, the target acquisition channel is used to obtain target video data from the target analog camera, the target chip is used to perform digital-to-analog conversion on the target video data, the target output channel is used to transmit the target video data after the digital-to-analog conversion to the main control end, and the target encoding module of the main control end is used to encode the target video data after the digital-to-analog conversion to obtain the target code stream;

[0048] like Figure 5 The system block diagram of the main control end is shown, including: video input end VI, video processing unit VPSS, video encoding unit VENC, video output end VO. VENC can perform main stream encoding, auxiliary stream encoding, JPEG encoding, and VO can preview and display.

[0049] After performing a reset operation on the target acquisition channel and the target output channel of the target chip, if the target application still cannot obtain the target code stream from the main control end, it is determined that the cause of the zero code stream abnormality is that the target chip is abnormal, or the main control end is abnormal, or the target analog camera is abnormal, or the coaxial cable between the target analog camera and the target device is abnormal.

[0050] Determine whether the code streams of other output channels of the target chip are all abnormal, and if so, determine that the cause of the zero code stream abnormality is that the target chip is abnormal;

[0051] If not, determining a normal output channel among the multiple output channels included in the target chip as the first output channel;

[0052] After the target acquisition channel is bound to the first output channel, if the target application obtains the target code stream from the master control end, it is determined that the cause of the zero code stream abnormality is that the target analog camera is abnormal, or the coaxial cable between the target analog camera and the target device is abnormal;

[0053] If the target application still cannot obtain the target code stream from the main control end of the target device, it is determined that the cause of the zero code stream abnormality is that the main control end is abnormal.

[0054] When it is determined that the cause of the zero code stream abnormality is the abnormality of the master control end, a reset operation is performed on the target encoding module.

[0055] In the case of the third abnormality type, it is determined that the cause of the zero code stream abnormality is the abnormality of the master control end. In the case of determining that the cause of the zero code stream abnormality is the abnormality of the master control end, a target encoding module is reset.

[0056] Optionally, the executor of the above steps may be a background processor, or other devices with similar processing capabilities, or a machine that integrates at least an image acquisition device and a data processing device, wherein the image acquisition device may include a graphics acquisition module such as a camera, and the data processing device may include a computer, a mobile phone or other terminal, but is not limited thereto.
