By the technical scheme, an input code stream to be sent of the relay IPC equipment in the cascade system and an output code stream allowed to be sent by the relay IPC equipment are obtained; according to the size relation between the input code stream and the output code stream, the code streams of the relay IPC equipment and the IPC equipment at the lower level of the relay IPC equipment are adjusted, so that the adjusted input code stream is matched with the output code stream.
In the embodiment of the present invention, adjusting the code stream of the relay IPC device and the IPC device at the lower level of the relay IPC device according to the size relationship between the input code stream and the output code stream includes: under the condition that the size relation indicates that the input code stream is larger than the output code stream, detecting whether the code stream configuration of the target relay IPC equipment and all lower-level IPC equipment reaches the minimum value of the adjustable range of the code stream; if not, acquiring the priority information of the relay IPC equipment and all lower-level IPC equipment; and based on the priority information, sequentially reducing the code stream of the lower IPC equipment in the order of the priority from low to high so as to match the adjusted input code stream with the output code stream.

In the embodiment of the present invention, adjusting the code streams of the relay IPC device and the IPC device at the lower level of the relay IPC device according to the size relationship between the input code stream and the output code stream includes: under the condition that the size relation indicates that the input code stream is less than or equal to the output code stream, detecting whether the code stream configuration of the relay IPC equipment and all lower IPC equipment reaches the maximum value of the code stream adjustable range; if not, acquiring the priority information of the relay IPC equipment and all the lower IPC equipment; and sequentially up-regulating the code stream of the lower-level IPC equipment according to the priority from high to low based on the priority information so as to match the regulated input code stream with the output code stream. By knowing the size relationship between the input code stream and the output code stream of the relay IPC equipment, when the input code stream is smaller than or equal to the output code stream, whether the code stream configuration of the target relay IPC equipment and all lower-level IPC equipment is adjusted to the maximum value of the adjustable range is detected, and the code stream configuration of the lower-level IPC equipment is adjusted up from high to low according to the priority information in the target relay IPC equipment, so that the output code stream is matched with the size of the input code stream.
By the embodiment, when the input code stream in the target relay IPC equipment is less than or equal to the output code stream, the code stream configuration of the relay IPC equipment and all the lower IPC equipment is sequentially adjusted up according to the priority order, so that the whole codes of the equipment in the whole network adapt to network change, and the transmission quality of the priority equipment is ensured.
In the embodiment of the present invention, before the code stream of the lower IPC device is sequentially up-regulated according to the order of priority from high to low so that the regulated input code stream is matched with the output code stream, the method further includes: and determining whether a down-regulation object for down-regulating the code stream of the lower-level IPC equipment is the relay IPC equipment, and if so, sequentially up-regulating the code stream of the lower-level IPC equipment according to the sequence of the priority from high to low so as to match the regulated input code stream with the output code stream. The code stream of the lower IPC equipment is sequentially up-regulated according to the sequence of the priority from high to low, namely before the up-regulation of the code stream of the lower IPC equipment, whether the relay IPC equipment which needs the up-regulation of the code stream of the lower IPC equipment currently and the relay IPC equipment which enables the down-regulation of the code stream of the lower IPC equipment before are the same or not needs to be confirmed, if yes, the code stream configuration of the lower IPC equipment is regulated according to the priority from high to low, and the output code stream is matched with the input code stream in size.
In the embodiment of the present invention, before or after obtaining an input code stream to be sent by a relay IPC device and an output code stream allowed to be sent by the relay IPC device in a cascade system, the method further includes: receiving at least one of the following information uploaded by the lower IPC device of the relay IPC device: the device identification is used for uniquely identifying the IPC device, the code stream configuration is used for indicating the actual code stream size of the current IPC device, the code stream adjustable range is used for indicating the upper limit and the lower limit of the code stream allowed to be adjusted by the current IPC device, the priority information is used for indicating the priority of the current IPC device, the corresponding link is used for indicating the link of the current IPC device, and the down-regulation regulator is used for indicating the IPC device commanding the current IPC device to down-regulate the code stream.
By the embodiment, when the input code stream to be sent of the relay IPC equipment in the cascade system and the output code stream allowed to be sent by the relay IPC equipment are obtained, equipment identification information used by lower-level IPC equipment for identifying the IPC equipment, the code stream configuration size allowed to be adjusted by the IPC equipment, priority information of the IPC equipment, corresponding link information indicating a current IPC equipment link, and indication information sent by a down-regulation regulator for down-regulating the code stream of the IPC equipment can be received. According to the acquired information, the accuracy of IPC equipment code stream configuration is ensured, and the whole code of the equipment in the whole network adapts to the network change condition.
The flow of the code stream adjusting method is explained with reference to an example, but the flow is not limited to the technical solution of the embodiment of the present invention. In order to better understand the technical solutions of the embodiments and the alternative embodiments of the present invention, the following description is made on possible meanings of the terms in the embodiments and the alternative embodiments of the present invention, but is not intended to limit the meanings of the following terms:
terminal IPC (equivalent to lower IPC): the front end IPC in the network topology, no other IPC relays to the IPC;
non-terminal IPC (equivalent to relay IPC): the IPC of the nodes in the network topology has other IPCs relayed to the IPC;
code stream configuration: the actual code stream size of the current IPC;
the code stream can be adjusted in range: the current IPC allows the lower limit and the upper limit of the code stream to be adjusted;
priority: the IPC importance degree of user configuration is reflected;
and the corresponding link: the IPC is obtained through which link, and the IPC passes through a unique link of the IP addresses and the port identifiers of the home terminal and the opposite terminal;
the down-regulation regulator: if some IPC code stream is adjusted downwards, who is the trigger.
Based on the above concept, the present invention provides a method for adjusting a code stream, so as to ensure the transmission quality of a high-priority device, and adapt the overall coding of the device in the entire network to the network change. As shown in FIG. 3, in the cascade system, the front-end devices IPC2/IPC3 are connected to the back-end storage device through IPC1 as a relay, and IPC4/IPC5 are connected to the storage device through a relay to IPC3 and then to IPC 1. In an actual use environment, because different front-end devices are deployed at different positions, the requirements of users on the image quality and the clamping condition of different devices are different, and the importance of different front-end devices is also different. The method provided by the embodiment of the invention mainly aims to preferentially ensure the transmission quality of the high-priority equipment in the scene.
For non-terminal front-end devices in the system (having other front-end device relay links, which is equivalent to the relay IPC device in the embodiment of the present invention), the following method is used to ensure the quality and the fluency of the high-priority devices (the topology of fig. 3 is taken as an example for the present embodiment). In this system, it is assumed that the importance of the user to the device is: IPC3> IPC5>1pc2=1pc1> -IPC 4.
Initial state: each front end IPC sends its own coding configuration information, coding adjustable range, equipment priority and link information to upstream nodes, and each passing non-terminal IPC equipment records the equipment information and continues reporting until reaching the storage equipment. The IPC1 in fig. 3 forms the device information table as follows:
Figure BDA0002313872610000101
the IPC3 forms device information as follows:
Figure BDA0002313872610000102
the non-terminal IPC process in the operating state is shown in fig. 4, and includes the following steps:
step 1: each IPC counts the sum of code streams inBit (which can be understood as the sum of data to be transmitted by the relay IPC equipment and data to be transmitted by the lower-level IPC equipment of the relay IPC equipment) relayed to all front-end equipment of the IPC (including the IPC) and counts the sum of code streams outBit (which is equivalent to the capacity of the relay IPC equipment capable of transmitting data) output by the IPC equipment, if inBit is greater than outBit, the step 7 is executed, otherwise, the step 2 is executed;
step 2: if the network sending capacity is higher than or equal to the sum of the code streams of the current equipment, executing code stream up-regulation, and executing the step 3;
and step 3: if the current code stream configuration sum of all the child nodes is the sum of the maximum value of the adjustable range (the current is the upper limit capable of being adjusted), the up-adjustment is abandoned, the step 1 is continuously executed, and if the space can be adjusted, the step 4 is executed;
and 4, step 4: checking an own equipment information table, wherein the own equipment information table and the lower node are not the maximum value absolutely, collecting the equipment (whether the code stream is adjusted by the IPC of the relay or not, and possibly other relays send out an over-and-down instruction) of which the down-regulation adjuster is the own equipment, if not, executing the step 1, otherwise, executing the step 5;
and 5: in the device list with the down-regulation regulator as the self, the priority is from high to low, whether the current configuration of the device is the highest configuration of the code stream or not is checked in sequence, if not, the IPC coding configuration is up-regulated to the highest value of the adjustable range of the code stream;
step 6: when adjusting the code stream, determining which link to send a down-regulation command, finding the link of the corresponding link to search the target IPC, issuing code stream adjustment information, and deleting the adjuster information of the IPC of a down-regulation adjuster;
and 7: if the network sending capability is lower than the sum of the code streams of the current equipment, executing code stream down regulation, and executing the step 8;
and 8: if the current sum of all the child node code stream configurations is the sum of the minimum value of the adjustable range (the current sum is the lower limit capable of being adjusted downwards), giving up the adjustment downwards, and continuing to execute the step 1, otherwise, executing the step 9;
and step 9: checking an own equipment information table, sequentially checking whether the current configuration of the equipment is the lowest configuration of the code stream from low to high in priority, if not, gradually reducing IPC (inter-process control) coding configuration to the lowest value one by one according to the total amount of the code stream required to be reduced, wherein the reduced total amount is from inBit to outBit;
step 10: and searching an IPC link needing to be adjusted downwards, issuing code stream adjustment information and adjuster information, and recording the IPC adjustment person to be adjusted downwards as the IPC adjustment person.
It should be noted that, the steps 1 to 10 are not used to limit the execution steps of the alternative embodiment of the present invention, and the sequence of the steps may be changed if necessary, which is not limited in the embodiment of the present invention.
In addition, for all IPC devices in the cascade system receiving the code stream adjustment request, if the IPC devices need to perform code stream adjustment, the IPC devices perform code stream adjustment, refresh the device information tables of the IPC devices and report the code stream configuration, the adjustable range and the priority of the IPC devices step by step; if the self-execution is not needed, searching a self-equipment information table and informing the self-equipment information table through a corresponding link; the non-terminal IPC receives the report information, refreshes an equipment information table of the non-terminal IPC and reports the report information until the non-terminal IPC stores the information; in the whole network, each node counts the input and the output of the node, and if the input is greater than the output, the node with the lowest priority is found out to be lowered; when the lifting platform rises, only the lifting platform can find out the descending of the lifting platform at the moment, and if the lifting platform does not descend, the lifting platform cannot lift.
Through the embodiment, in the cascade system, the whole cascade full-network linkage is carried out according to the important level of IPC, the IPC code stream with low priority is preferentially reduced, and the transmission quality of high-priority equipment in the whole cascade system is ensured.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
