[0002] For a digital video recorder (DVR) product, a video signal collected by an analog camera is converted by a video decoding chip into an analog-digital converter (ADC) and is decoded to color-coded YUV data, which is transmitted to a central processing unit (CPU) through a BT656 / BT1120 interface, so as to realize real-time preview, storage and forwarding of the video.

[0031] In the embodiments of the present application, a video signal transmission method is provided, Figure 2 is a flowchart of the video signal transmission method according to the embodiments of the present application, as shown in Figure 2 The flowchart includes the following steps:

[0032] In step S202, the system determines the standard of the camera device accessed by the camera device, wherein the camera device is used to acquire a video signal.

[0033] In this embodiment, for example, the specification of the camera device includes: 4KP30, 4KP15, 1080P30, 720P30, and the like.

[0034] In step S204, the output mode of the target transmission interface is determined based on the specification of the camera device.

[0035] For example, when the specification of the camera device accessed by the camera device is 4KP30, the BT1120 output mode is adopted; when the specification of the camera device accessed by the camera device is 4KP15, 1080P30, or 720P30, the BT656 output mode is switched to by a self-adaptive method through the VO port, so as to reduce the power consumption of the product.

[0036] In step S206, the video signal is transmitted to the central processing unit according to the output specification of the target transmission interface, wherein the central processing unit is configured to process the video signal.

[0037] For example, the CPU performs real-time preview, storage, and forwarding processing on the video signal.

[0038] The execution subject of the above steps can be a terminal, but is not limited thereto.

[0039] Through the above steps, the specification of the camera device accessed by the camera device is determined, wherein the camera device is configured to acquire the video signal; the output mode of the target transmission interface is determined based on the specification of the camera device; and the video signal is transmitted to the central processing unit according to the output mode of the target transmission interface, wherein the central processing unit is configured to process the video signal. The purpose of switching the transmission interface based on the specification of the camera device is achieved. The power consumption of the product is reduced. Therefore, the problem of high data processing power consumption in the related art can be solved, and the effect of reducing the power consumption of data processing is achieved.

[0040] In one example embodiment, the output mode of the target transmission interface is determined based on the specification of the camera device, including one of the following:

[0041] In S11, in a case where the specification of the camera device accessed by the camera device includes a first specification, the output mode of a first transmission interface corresponding to the first specification is determined as the transmission mode of the target transmission interface.

[0042] In S12, in a case where the specification of the camera device accessed by the camera device includes a second specification, the output mode of a second transmission interface corresponding to the second specification is determined as the transmission mode of the target transmission interface.

[0043] In this embodiment, the first specification includes but is not limited to 4KP30. The second specification includes but is not limited to 4KP15, 1080P30, and 720P30.

[0044] For example, when the accessed camera is a 4K P30, a BT1120 output mode is adopted; when the accessed camera is a 4K P15, a 1080P30 or a 720P30 standard, a BT656 output mode is switched to by a self-adaptive method through a VO port, so as to reduce product power consumption.

[0045] In one example embodiment, transmitting the video signal to the central processor according to the output mode of the target transmission interface comprises:

[0046] S21, in a case where the standard of the camera device accessed by the camera equipment includes a second standard, decoding the video signal to obtain a decoded video signal;

[0047] S22, transmitting the decoded video signal to the central processor according to low eight bits in four transmission channels in an output mode of a second transmission interface, wherein high eight bits of the four transmission channels in the output mode of the second transmission interface are closed.

[0048] In the embodiment, the four transmission channels include but are not limited to output interfaces outputting video data, for example, VO1, VO2, VO3 and VO4 as shown in Figure 3 .

[0049] In one example embodiment, transmitting the video signal to the central processor according to the output mode of the target transmission interface comprises:

[0050] S31, in a case where the standard of the camera device accessed by the camera equipment includes a second standard, decoding the video signal to obtain a decoded video signal;

[0051] S32, transmitting the decoded video signal to the central processor through low eight bits in a first transmission channel and a second transmission channel in an output mode of a second transmission interface, wherein high eight bits of the first transmission channel and the second transmission channel in the output mode of the second transmission interface are closed, and third transmission channel and fourth transmission channel in the output mode of the second transmission interface are closed.

[0052] For example, when the accessed analog camera is a 4K P15, four groups of transmission channels are configured in a BT656 mode, low eight bits of the BT656 signal are outputted, and high eight bits which are not used are closed for output. The configuration is a BT656 1x mode.

[0053] For example, as shown in Figure 4 , low eight bits in the first transmission channel VO1 and the second transmission channel VO2 transmit the decoded video signal to the CPU. The third transmission channel VO3 and the fourth transmission channel VO4 are closed.

[0054] In one example embodiment, transmitting the video signal to the central processor according to the output mode of the target transmission interface comprises:

[0055] S41, in the case where the format of the camera device accessed by the camera equipment includes the first format, decoding the video signal to obtain a decoded video signal;

[0056] S42, in the case where the low eight bits of the transmission channel in the output mode of the first transmission interface are abnormal, closing the low eight bits of the transmission channel in the output mode of the first transmission interface;

[0057] S43, transmitting the decoded video signal to the central processor by using the high eight bits of the transmission channel in the transmission mode of the first transmission interface.

[0058] For example, when the accessed analog camera is 1080P30, the 3rd and 4th channel video outputs are closed, the 1st and 2nd channel outputs are configured in the BT656 mode, the low 8-bit BT656 signal is output, and the unused high 8-bit is closed. The configuration is in the BT656 2x mode.

[0059] For example, when the accessed camera is 4KP30, but the low 8-bit signal line of the BT1120 signal of VO4 is abnormal, the low 8-bit output of VO4 can be closed, the high 8-bit BT656 signal is output, and the configuration is adjusted to the BT656 1x mode. At this time, the system adjusts the camera to the 4KP15 mode through the reverse control function, and simultaneously alarms. Thus, the camera is always in the monitoring state, and the phenomenon of video loss due to hardware link abnormality is avoided.

[0060] In one example embodiment, after transmitting the decoded video signal to the central processor by using the high eight bits of the transmission channel in the transmission mode of the first transmission interface, the method further comprises:

[0061] S61, adjusting the format of the camera device accessed by the camera equipment to the second format;

[0062] S62, issuing a first prompt information, wherein the first prompt information is used to prompt that the camera device of the first format is abnormal.

[0063] For example, the camera device is adjusted to the 4KP15 mode, and simultaneously alarms.

[0064] In one example embodiment, transmitting the video signal to the central processor according to the output mode of the target transmission interface comprises:

[0065] S71, in the case where the format of the camera device accessed by the camera equipment includes the second format, decoding the video signal to obtain a decoded video signal;

[0066] S72, if the lower eight bits of the transmission channel in the output mode of the second transmission interface are abnormal, disable the output of the lower eight bits of the transmission channel in the output mode of the second transmission interface.

[0067] S73 uses the high eight bits of the transmission channel in the output mode of the second transmission interface to transmit the decoded video signal to the central processing unit.

[0068] For example, when the connected camera is a 4KP15, it is configured in BT656 1x mode. If a signal line of the lower 8 bits of the BT656 signal of VO1 malfunctions, the lower 8 bits of VO1 can be turned off and the higher 8 bits can be turned on, and VO1 will still use BT656 1x mode.

[0069] In one exemplary embodiment, after transmitting the decoded video signal to the central processing unit using the high eight bits of the transmission channel in the output mode of the second transmission interface, the method further includes:

[0070] S81, issue a second prompt message, which is used to indicate that the camera device using the second standard is malfunctioning.

[0071] For example, the system can use a reverse control function to adjust the camera to 4KP15 mode and simultaneously trigger an alarm.

[0072] The present invention will now be described in conjunction with specific embodiments:

[0073] This embodiment achieves the goal of reducing product power consumption and enhancing system reliability through the VO port adaptive method.

[0074] like Figure 3 As shown, when the connected analog camera is a 4KP30, the BT1120 1x mode is used to decode the video signal. When the connected analog camera is a 4KP15, the four outputs are configured in BT656 mode, using the lower 8 bits to output the BT656 signal, and the unused higher 8 bits are disabled. The configuration is BT656 1x mode.

[0075] like Figure 4 As shown, when the connected analog camera is 1080P30, video output channels 3 and 4 are disabled, and output channels 1 and 2 are configured in BT656 mode, using the lower 8 bits to output the BT656 signal, while the unused higher 8 bits are disabled. This is configured as BT656 2x mode.

[0076] like Figure 5As shown, when the connected camera is a 4KP30, but one of the lower 8 signal lines of the BT1120 signal on the VO4 is abnormal, the lower 8 bits of the VO4 output can be turned off, and the higher 8 bits can be output as the BT656 signal, adjusting it to BT656 1x mode. At this time, the system will use the reverse control function to adjust the camera to 4KP15 mode and simultaneously trigger an alarm.

[0077] like Figure 6 As shown, when the connected camera is a 4KP15, it is adaptively configured to BT656 1x mode according to our solution. When an anomaly occurs in one of the lower 8 signal lines of the BT656 signal of VO1, the lower 8 bit output of VO1 can be turned off, while the higher 8 bit output can be turned on. VO1 will still use BT656 1x mode. In this case, although an anomaly occurs, it has no actual impact, and an alarm will be triggered simultaneously.

[0078] In summary, this embodiment, for DVRs requiring 4KP30 cameras, uses the BT1120 output mode when the connected camera is a 4KP30; when the connected camera is a 4KP15, 1080P30, or 720P30 camera, it switches to the BT656 output mode via VO port adaptive method to reduce power consumption. If any signal line of the BT1120 malfunctions, the BT656 output mode is switched via VO port adaptive method to reduce camera resolution, thereby ensuring the camera remains in monitoring mode and preventing video loss due to hardware link failures.
