2. Video networking packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
| DA | SA | Reserved | Payload | CRC |
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
| DA | SA | Reserved | label (R) | Payload | CRC |
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
Based on the above characteristics of the video networking, one of the core concepts of the embodiments of the present invention is provided, in which, following a protocol of the video networking, the recording and playing management platform receives video control information sent by the first terminal, and pushes the video resource in the recording and playing management platform to the second terminal according to a terminal identifier of the second terminal in the video control information, and then the second terminal controls the video resource to be played according to a playing control command sent by the first terminal, so that the first terminal can push the video resource on the recording and playing management platform to the second terminal and control the playing of the video resource, and the control of the video playing in the video networking is more flexible and convenient.
Referring to fig. 5, a flowchart of a video playing control method according to an embodiment of the present invention is shown.
When video playing control is performed, the first terminal can send video control information to the recording and playing management platform by using a video networking protocol. The video control information includes a play control command, a terminal identifier of the second terminal, and a resource identifier of the video resource. The playback control command is a command for controlling playback, such as playback, pause, stop, or fixed-point playback. The terminal identification of the second terminal is a unique identification for identifying the second terminal, and the recording and broadcasting management platform can be accurately connected to the second terminal through the terminal identification of the second terminal. The resource identifier of the video resource is an identifier for distinguishing each video resource, and the video resource which needs to be played and controlled can be determined through the resource identifier.
Specifically, in order to enable the recording and playing management platform to receive the video control information sent by the first terminal, the first terminal needs to be first networked. In the video network, each terminal including the first terminal needs to access the network to realize communication. Each terminal allowed to access the network must be registered in the node server, and terminals which are not registered cannot access the network. The process of accessing the network by the terminal comprises the following steps:
s1, the node server sends a query packet to each port, and the terminal sends a response packet after receiving the query packet, wherein the response packet comprises the registration information of the terminal;
s2, after receiving the response packet sent by the terminal, the node server knows which terminal (set-top box, coding board or memory) is connected to which port, then finds the information of the terminal in the registration information table in the node server, sends the network access command (telling the access network address of the terminal) to the terminal, and the terminal accesses the network after receiving the network access command and sends the network access command response to the node server;
s3, the node server receives the response of the network access command from the terminal to know that the terminal has accessed the network, and then sends a state inquiry packet to the port at regular time to check whether the terminal is working normally. And if the terminal works normally, the terminal sends a state query response to the node server after receiving the state query packet. When the node server does not receive the state inquiry response within a period of time, the node server considers that the terminal is moved out of the network, does not send the state inquiry packet any more, and continues to send the inquiry packet to the port.
In practical application, after a first terminal accesses a network, the recording and broadcasting management platform may receive a connection request sent by the first terminal in the video network, where the connection request includes a data request based on a websocket protocol. After the recorded broadcast management platform receives the connection request, the recorded broadcast management platform can respond to the connection request to establish a full-duplex communication link between the recorded broadcast management platform and the first terminal. The full duplex communication means that data can be simultaneously transmitted in two directions, that is, data can be received while data is transmitted, and both can be performed synchronously. Therefore, the recording and broadcasting management platform can actively send information to the second terminal through the full-duplex communication link established between the recording and broadcasting management platform and the first terminal. When the video resources managed by the recording and broadcasting management platform are updated, the video resources can be reflected in the first terminal in time, so that the first terminal can accurately play and control the video resources through the recording and broadcasting management platform.
And 502, the recording and playing management platform pushes the video resource and the playing control command corresponding to the resource identifier to the second terminal according to the terminal identifier of the second terminal.
After the recording and playing management platform receives the video control information sent by the first terminal, it can determine that the first terminal needs to control the video playing of the second terminal according to the terminal identifier of the second terminal in the video control information. After the target needing to be controlled is determined, the video resource and the playing control command corresponding to the resource identifier in the video control information can be pushed to the second terminal, so that the second terminal can know the video resource needing to be controlled and how to control the video resource. Specifically, in order to enable the recording and playing management platform to push the video resource and the playing control command to the second terminal, the second terminal needs to be first networked, and the process of networking the terminal is as described in step 501.
In practical applications, a full-duplex communication link may be established between the recording and playing management platform and the second terminal before the video resource and the playing control command are pushed to the second terminal. Specifically, the recording and broadcasting management platform may send a connection request to a second terminal in the video network, and receive a response from the second terminal to the connection request, so as to establish a full-duplex communication link between the recording and broadcasting management platform and the second terminal. Wherein the connection request comprises a data request based on a websocket protocol.
And step 503, the second terminal controls the video resource to play according to the play control command.
After the second terminal receives the video resource and the play control command corresponding to the resource identifier, that is, after the second terminal knows the video resource to be controlled and how to control the play control command of the video resource, the video resource can be controlled to be played according to the play control command. For example, if the video resource received by the second terminal is a link address pointing to the video a, and the play control command received by the second terminal is play, the second terminal acquires the video a from the server by using the link address of the video a and plays the video a. And if the playing control command received by the second terminal is pause, the second terminal pauses the playing progress of the video A according to the playing control command. Thereby realizing the control of the video resource playing.
In summary, in the embodiments of the present invention, the recording and playing management platform receives the video control information sent by the first terminal, and pushes the video resource and the playing control command corresponding to the resource identifier to the second terminal according to the terminal identifier of the second terminal. Therefore, the second terminal can control the video resource to be played according to the playing control command sent by the first terminal. And further, the control on video playing in the video network is more flexible and convenient.
Referring to fig. 6, a flowchart of another video playback control method according to an embodiment of the present invention is shown.
Specifically, when the first terminal receives the first operation, the pop-up window displayed by the first terminal may include a first input area, a second input area, a play instruction control, and a play progress control. The first input area is used for inputting a terminal identifier of a second terminal, the second input area is used for inputting a resource identifier of a video resource, the play instruction control can be used for realizing control operations such as playing, pausing or stopping of a video, and the play progress control can be used for selecting the play progress, so that fixed-point play is realized, namely video content at a specific time point is played. For example, if the browser of the first terminal can log in the recording and playing management platform, when the recording and playing management platform is logged in the browser of the first terminal, a video resource list as shown in fig. 7 may be displayed on an interface of the browser, where each video resource corresponds to one push key. After a push key corresponding to a certain video resource is triggered, a popup can be displayed in the first terminal, wherein the triggering of the push key is a first operation received by the first terminal. In practical applications, the first operation is not limited to triggering the push key. The popup displayed by the first terminal may be the popup shown in fig. 8, and when the first operation has specified the video resource to be controlled, the popup may determine the resource identifier of the video resource included in the video control information without setting the second input area. If the first operation does not specify a specific video resource, the resource identifier of the video resource needs to be acquired through the second input area to determine the video resource which needs to be played and controlled. In practical application, various controls can be additionally arranged in the pop-up window to enrich the control function of video playing.
After the first terminal obtains the playing control command, the terminal identifier of the second terminal and the resource identifier of the video resource through various input areas and/or various controls displayed in the popup window, the video control information can be generated according to the playing control command, the terminal identifier of the second terminal and the resource identifier of the video resource.
In practical application, after the terminal identifier of the second terminal and the resource identifier of the video resource are acquired from the popup window once, which terminal in the video network needs to be controlled by the first terminal to play the video can be determined, and which video needs to be controlled specifically. Therefore, after the second terminal and the video resource corresponding to the resource identifier are determined, when the second terminal is controlled to play the video, only the play control command obtained from the popup window can be changed, and the terminal identifier of the second terminal and the resource identifier of the video resource are not repeatedly obtained until the play control of the video resource is terminated.
Specifically, when the first terminal receives the second operation, in order to send the video control information generated in the first terminal to the recording and broadcasting management platform, the first terminal may first establish a full-duplex communication link with the recording and broadcasting management platform. The second operation includes triggering a play instruction control or triggering a play progress control, for example, if the user clicks the play instruction control after completing the input of the related information in the input area to send the video control information, the second operation is the click play control instruction control. In order to enable the first terminal to send the video control information to the recording and broadcasting management platform, a full-duplex communication link between the first terminal and the recording and broadcasting management platform may be established first. Specifically, the recording and broadcasting management platform may receive a connection request sent by a first terminal in the video network, where the connection request includes a data request based on a websocket protocol. After the recorded broadcast management platform receives the connection request, the recorded broadcast management platform can respond to the connection request to establish a full-duplex communication link between the recorded broadcast management platform and the first terminal, so that the recorded broadcast management platform can receive video control information sent by the first terminal through the full-duplex communication link.
After a full-duplex communication link is established between the recording and broadcasting management platform and the first terminal, the recording and broadcasting management platform can receive the video control information sent by the first terminal through the full-duplex communication link.
Specifically, the recording and broadcasting management platform may determine the pushing target according to the terminal identifier of the second terminal. And determining the content pushed to the second terminal according to the resource identifier, wherein the pushed target is the second terminal in the video network, and the pushed content is the video resource corresponding to the resource identifier.
In practical application, before the recording and playing management platform pushes the video resource and the playing control command corresponding to the resource identifier to the second terminal according to the terminal identifier of the second terminal, a full-duplex communication link between the recording and playing management platform and the second terminal may be established. Specifically, the recording and broadcasting management platform may send a connection request to a second terminal in the video network, and receive a response from the second terminal to the connection request, so as to establish a full-duplex communication link between the recording and broadcasting management platform and the second terminal, where the connection request includes a data request based on a websocket protocol.
And 606, the second terminal controls the video resource to be played according to the playing control command.
When the second terminal receives the video resource sent by the recording and playing management platform for the first time and is required to play the video resource, if the video resource is a link address pointing to a certain video, the second terminal can first acquire the video corresponding to the link address from the server by using the link address and then play the video. After the second terminal has acquired the corresponding video, the playing of the video can be directly controlled according to the subsequently received playing control command. For example, when the second terminal receives a pause instruction sent by the first terminal through the recording and playing management platform, the second terminal may pause the video to realize the playing control of the first terminal to the second terminal. Since the first terminal and the second terminal can be located at different geographical positions, the first terminal can remotely control the second terminal through the method. In addition, when the second terminal is a set-top box, the computer can be used as the first terminal to replace the remote controller to perform play control on the second terminal under the condition of missing the remote controller.
In summary, in the embodiment of the present invention, the first terminal may display the popup window when receiving the first operation, and generate the video control information according to the play control command acquired from the popup window, the terminal identifier of the second terminal, and the resource identifier of the video resource. Therefore, after the recording and playing management platform analyzes the video control information, the video resource and the playing control command are pushed to the second terminal, so that the second terminal can timely and accurately carry out corresponding playing control on the video specified by the first terminal. Moreover, since the first terminal and the second terminal can be located at different geographical locations, the first terminal can remotely control the second terminal through the method.
