Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the disclosure and are not intended to limit the disclosure.
It should be noted that the terms "first," "second," and the like in the description and claims herein and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments herein described are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.
In this document, the term "and/or" is only one kind of association relationship describing the associated object, meaning that three kinds of relationships may exist. For example, a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
As described in the background, differences in the parameters of the hierarchical or physical channels can cause round-trip delays that make it unnecessarily difficult for a video source to transmit video data for different channels. Take the transmission of signaling as an example. When the round trip delay exists, the time for the signaling sent by the video source to reach the node and/or the video terminal is different. Meanwhile, the time for the nodes and/or the video terminals to feed back the signaling results is also different, so that the time for the fed-back signaling results to reach the video source is also different. For video data, the amount of video data is usually larger than that of signaling data, and therefore, the round trip delay has a larger influence on the transmission of the video data. When the video data are different, different nodes and/or video terminals cannot acquire correct video data on resources (time slots) through a predetermined pixel clock when transmitting and receiving the video data, and further, the nodes and/or the video terminals cannot normally display the video data.
Wherein, a level refers to the number of nodes and/or video terminals through which different nodes and/or video terminals in each transmission link reach the video source, for example, if a node and/or video terminal is directly connected to the video source, then starting from the video source, this node and/or video terminal is at level 2; and so on.

The transmission node in some embodiments of the disclosure may comprise a node and/or a video terminal.
In one embodiment, as shown in fig. 2, a multi-channel resource allocation method is provided, which is exemplified by applying the method to the video image processing system in fig. 1, and it is understood that the method can also be applied to other video image processing systems, and a video source in the video image processing system is used for allocating resources of each transmission node. The method comprises the following steps:
and S202, sending test data to each transmission node, wherein the test data is used for indicating each transmission node to feed back the time delay calculation data.
The test data may be data for calculating round trip delay between the video source and each transmission node. The test data may be a sequence, a signaling or other data, etc. The delay calculation data may be data fed back to the video source from the test data received by each transmission node, and may be some invalid data for measuring the round trip delay, which is only used for calculating the round trip delay of the video source. Round trip delay may generally be the delay between a video source sending data (e.g., video data or other signaling) to various transport nodes.
Specifically, the video source sends test data to each transmission node. And after receiving the test data, each transmission node feeds back corresponding time delay calculation data to the video source. And the video source calculates the round-trip delay between the video source and each transmission node according to the delay calculation data obtained by feedback.
And S204, determining a first transmission node with the same round-trip delay and a second transmission node without the same round-trip delay according to the delay calculation data.
Wherein the first transport node may typically be a transport node having the same round trip delay as the video source. I.e. the round trip delay between each first transport node and the video source is the same. The first transport node may comprise multiple classes. I.e. the round trip delay between the first transport node and the video source is the same for each class. For example, the first transport node includes both a and B classes. The round trip delay between the first transport node in class a and the video source is the same. The round trip delay between the first transport node in class B and the video source is the same. The round trip delay between the first transmission node in category a and the video source is typically not the same as the round trip delay between the first transmission node in category B and the video source. The second transport nodes may typically be all transport nodes except the first transport node, and typically the round trip delay between each second transport node and the video source is different.
Specifically, after calculating the round trip delay between each transmission node and each transmission node according to the delay calculation data, the transmission nodes corresponding to the same round trip delay may be grouped into one group, the transmission node of the group may be the first transmission node, and the remaining transmission nodes may be the second transmission nodes.
S206, determining a first resource allocation table according to the first round-trip delay of the first transmission node and the second round-trip delay of the second transmission node, where the first resource allocation table is used to indicate the resources of the video data sent by the video source to the first transmission node and the second transmission node, and the resources of the video data received by the first transmission node and the second transmission node.
Wherein the first resource allocation table is a table for negotiating resources required for transmitting data between the video source and the first and second transmission nodes when there is no new data transmission. After negotiation, the video source sends video data to the first transmission node and the second transmission node according to the negotiated resource allocation table (the first resource allocation table).
In particular, because there is a round trip delay between the video source and the first and second transport nodes. Therefore, if the video data is transmitted by allocating resources according to the resource allocation table set when the round trip delay does not exist, it may happen that the transmission node cannot correctly receive the video data, and the video data cannot be normally displayed. Therefore, the previously set resource allocation table needs to be adjusted according to the first round trip delay of the first transmission node and the second round trip delay of the second transmission node, so as to determine the first resource allocation table.
S208, allocating the resources of the first transmission node and the second transmission node according to the first resource allocation table.
In particular, since the first resource allocation table is determined by the first round trip delay and the second round trip delay. The resources of the first and second transmission nodes may thus be allocated according to the first resource allocation table. Subsequently, when the video source transmits video data to the first transmission node or the second transmission node, the video source may also transmit the video data according to the first resource allocation table. The first transport node and the second transport node may also receive video data according to the first resource allocation table. The first transmission node receives video data according to the same resource allocated in the first resource allocation table, so as to realize resource multiplexing.
It will be appreciated that in some embodiments of the present disclosure, references to resources (timeslots) in some embodiments of the present disclosure generally refer to video data as well as some timing parameters such as resolution and refresh rate. The resources may generally refer to resources in a frame structure.
In some exemplary embodiments, the video source may allocate resources according to the table 1 isochronous multiplexing allocation table.
Table 1 synchronous multiplex allocation table
In the multi-channel resource allocation method, the time delay calculation data of each transmission node can be obtained through the test data, and the round-trip time delay between the video source and each transmission node can be determined through the time delay calculation data. And determining a first resource allocation table according to the round trip delay. There is usually a delay gap between the video source and each of the transmission nodes. Therefore, the actual physical channel situation can be considered, and the effectiveness of resource allocation is obviously improved. And determining a first resource allocation table according to the first round trip delay of the first transmission node and the second round trip delay of the second transmission node. The first transmission nodes with the same round-trip delay are classified into one class, so that resources can be multiplexed, and the resource utilization rate is greatly improved. By re-determining the resource allocation table according to the round-trip delay sequence, the pixel clock of the node and/or the video terminal and the received video data can be ensured to be synchronous, correct video data reception is completed, and the video data can be normally displayed.
In one embodiment, as shown in fig. 3, in case that the remaining allocated resources satisfy the resources required to be occupied by each of the transmission nodes, the method further includes:
and S302, determining the round-trip delay of each transmission node according to the delay calculation data.
S304, determining a second resource allocation table for allocating resources of each transmission node according to the round trip delay of each transmission node, where the second resource allocation table is used to indicate resources of video data sent by the video source to each transmission node and resources of video data received by each transmission node.
S306, allocating resources of each transmission node according to the second resource allocation table.
Specifically, the video source has received the delay data fed back by each transmission node. When the video source determines that there are remaining resources after the allocated resources, which are enough for all the transmission nodes to use different resources for transmitting or receiving video data, the video source may not need to group the transmission nodes with the same round trip delay. And directly determining the round-trip delay corresponding to each transmission node. And adjusting the resource allocation table according to the round-trip delay corresponding to each transmission node, and determining a second resource allocation table for allocating the resources of each transmission node after adjustment. And the video source allocates the resources of each transmission node according to the second resource allocation table.
In some exemplary embodiments, the video source may also allocate resources of each transport node in the manner of a latency allocation table in the manner of table 2.
TABLE 2 delay Allocation Table
In this embodiment, when the remaining allocation resources satisfy the resources occupied by each transmission node, the scheme mentioned in this embodiment may be used to allocate the same resources according to the transmission node with the medium round-trip delay of each transmission node, which may result in a low complexity of implementation. And each transmission node can also be ensured to normally receive and display the video data under the condition of round-trip delay.
In an embodiment, after allocating the resources of each transmission node or allocating the resources of the first transmission node and the second transmission node, the video source may send video data to each transmission node, and each transmission node may normally display the video data.
In one embodiment, before sending the test data to each of the transmission nodes, the method further includes:
and determining a resource allocation table according to the resources occupied by each transmission node.
Specifically, in a general current situation, a conventional resource allocation manner is to allocate resources occupied by video data transmission of each transmission node. And updating the corresponding resource allocation table after allocating the resources. Each transmission node transmits or receives video data according to the resource allocation table. However, this approach does not take into account the presence of round trip delays. Therefore, the resource allocation table needs to be adjusted according to the round trip delay determination.
Determining a first resource allocation table, comprising:
adding a first round-trip delay to a resource occupied by a first transmission node in a resource allocation table, and adding a second round-trip delay to a resource occupied by a second transmission node to obtain an added resource allocation table;
and determining a first resource allocation table according to the increased resource allocation table.
In particular, a first round trip delay may be added to the resource occupied by the first transport node in the resource allocation table. After the first round-trip delay is increased, when the corresponding first transmission node receives the video data, the first round-trip delay needs to be received first. And after the first round-trip delay is received, receiving the video data through the resource. When the resources occupied by each first transmission node are different, the video data can be transmitted by using the delayed resources increased by the first transmission node occupying the most resources in general. To ensure that each first transmission node has sufficient resources to transmit the video data. And increasing a second round trip delay on the resource occupied by the second transmission node in the resource allocation table. After the second round-trip delay is increased, when the corresponding second transmission node receives the video data, the second round-trip delay needs to be received first. And after the second round-trip delay receiving is finished, receiving the video data through the resources occupied by the second transmission node.
The determining a second resource allocation table for allocating resources of each of the transmission nodes includes:
and increasing the round-trip delay corresponding to each transmission node on the resources occupied by each transmission node in the resource allocation table, and determining a second resource allocation table for allocating the resources of each transmission node.
In particular, the resource occupied by each transport node is indicated in the resource allocation table, since there is a corresponding round trip delay for each transport node. Thus, a corresponding round trip delay may be added to the resources occupied by each transport node. After the corresponding round-trip delay is increased, when each corresponding transmission node receives video data, the corresponding round-trip delay needs to be received first. And after the corresponding round-trip delay is received, receiving the video data through the corresponding occupied resource.
In some exemplary embodiments, the manner of increasing the round trip delay may be to increase a round trip delay sequence on the corresponding occupied resource. The round trip delay sequence is used to mark the round trip delay, which is actually a series of symbols, and since the video source transmits each symbol according to the clock, each symbol represents a certain time, and thus the series of symbols represents the time required to transmit the symbols, when the video data is received by each transmission node, the round trip delay sequence symbols represent a specific time required to receive the symbols, that is, after a specific time delay, the valid video data is received by the corresponding resource. It should be noted that, here, the round trip delay is only increased by the round trip delay sequence, and those skilled in the art may select different ways to increase the round trip delay according to actual situations, and the embodiment of the present disclosure is not limited to a specific way.
In some embodiments, for example, there are also round trip delay sequences in the original resource allocation table, the round trip delay sequences being 1ms and 2ms round trip delay sequences. And the round-trip delay of a corresponding transmission node is 3ms, the video source will add a round-trip delay sequence of 3ms to the resource corresponding to the transmission node in the original resource allocation table.
In this embodiment, by adding a corresponding round-trip delay to a resource occupied by each transmission node (including a first transmission node and a second transmission node) in the resource allocation table, when each transmission node receives video data, the round-trip delay is received first to ensure that a pixel clock of each transmission node and the received video data are synchronized, so as to complete correct video data reception and display.
In one embodiment, the method further comprises: and distributing the resources of each transmission node through a pre-constructed resource distribution frame structure.
The resource allocation frame structure is improved on the standard frame structure, and is used for distributing resources of each transmission node (including a first transmission node and a second transmission node) by a video source.
As shown in fig. 4, the allocating the resources of each transmission node through the pre-constructed resource allocation frame structure includes:
s402, confirming the round-trip delay of each transmission node through the round-trip delay confirmation time slot in the resource allocation frame structure.
S404, adjusting the resource multiplexing time slot in the resource allocation frame structure according to the round trip delay of each transmission node, and allocating the resources of each transmission node through the resource multiplexing time slot.
The round-trip delay confirmation time slot is used for sending test data to each transmission node, calculating data according to the delay fed back by each transmission node, and determining the round-trip delay of each transmission node; the resource multiplexing time slot is obtained by adjusting the pixel data time slot in the standard frame structure and is used for reallocating the resources of each transmission node according to the round-trip delay.
The standard frame structure may be as shown in fig. 5, where fig. 5 shows a schematic diagram of a standard data frame structure, and the standard frame structure may include: BS (Blanking Start), VB-ID (Vertical Blanking Identifier), mvid (timer value of Video data), naud (timer value of audio data), dummy Video (for Dummy data padding), BE (Blanking End), pixel data (for transmission of Video data), FS (Fill Start, padding Start), fill Video (padding data, for padding when there is insufficient data), and FE (Fill End).
While the resource allocation frame structure involved in some embodiments of the present disclosure may be an improvement over the standard frame structure. As shown in fig. 6, fig. 6 shows a schematic diagram of a resource allocation frame structure involved in some embodiments of the present disclosure. The resource allocation frame is a data frame structure obtained by adding a round-trip delay determination time slot on the basis of a standard frame structure and adjusting pixel data in the original standard frame structure into a resource multiplexing time slot.
Specifically, the video source may determine a time slot through round trip delay in the resource allocation frame structure, and send specified test data to enable the video source to determine round trip delay on different transmission nodes on different channels and different levels in the existing link topology structure. After determining the round-trip delay, the video source may allocate the resources of each transmission node according to the round-trip delay of each transmission node and through the resource multiplexing slot in the resource allocation frame structure. It is understood that the resource multiplexing time slot may allocate the resource of each transmission node in the manner of the resource allocation table described above. The resources of the transmitting node may also be allocated in other allocation manners. The resources may be allocated to the first transmission node and the second transmission node mentioned above, or may be allocated to each transmission node. For how to allocate resources by using the resource allocation table, reference may be made to the foregoing embodiments, and repeated description is not repeated here.
In an embodiment, after the resources of each transmission node are allocated or the resources of the first transmission node and the second transmission node are allocated, the video source may send the video data to each transmission node through a standard frame structure, and each transmission node may normally display the video data.
In the present embodiment, since the resource allocation frame is modified from the standard frame structure, it is compatible with the standard frame structure, and the transmission display of the video data in each transmission node is completed by occupying a small amount of resources (time slots) in the standard frame structure.
In one embodiment, the test data includes at least: video data and a preset feature sequence.
Specifically, when the test data is normal video data, the video source may not terminate video data transmission on multiple channels in the normal topology, complete round-trip delay detection, and complete seamlessly, but may cause abnormality to occur when each transmission node receives the video data, resulting in a display error. When a preset special sequence is adopted, normal video data transmission needs to be stopped, and the round-trip delay measurement is independently completed by the special sequence, at the moment, the measurement effect can be completed by designing the special sequence according to requirements so as to achieve specific precision, but cannot be completed seamlessly; the video source can flexibly select the type of the test data according to specific practical situations. Wherein, the seamless completion means that the seamless normal video data transmission and the round trip delay measurement can be performed simultaneously.
In one embodiment, the method further comprises: communicating with each transmission node through multiplexed signaling;
the multiplexing signaling includes at least:
an enable field for confirming whether to use the resource allocation method;

a test data indication field for determining test data used for calculating round trip delay;
and the feedback field is used for feeding back the time delay calculation data of each transmission node.

If not, a standard frame structure is used.

The resource allocation indication field is a synchronization and resource multiplexing state which is specifically completed when the resource allocation method is used, and is related to synchronization and resource multiplexing strategies which are actually used, generally, each strategy corresponds to one state, so that a video source can accurately position the synchronization and resource multiplexing conditions of each transmission node, and if the synchronization and resource multiplexing requirements are met, the video source can stop or start a synchronization and resource multiplexing procedure in any state at any time, so as to improve the flexibility as much as possible. For example, resources are currently allocated to each transmission node according to the steps as S302 to S306, but some transmission nodes are suddenly added or changes occur in transmission links, resulting in insufficient remaining resources. The allocation of resources may be performed at this time in steps such as S202 to S206.
