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), and is defined to be 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 characteristics of the video networking, one of the core concepts of the embodiments of the present invention is provided, and the obtained mark information is pushed to the video decoding IE plugin through the signaling gateway, and the video decoding IE plugin displays the mark corresponding to the identification information in the video window in which the video data is displayed, so as to realize the dynamic adjustment of the mark in the video window.

Referring to fig. 5, a flowchart of steps of an embodiment of a mark displaying method according to the present invention is shown, where the embodiment of the present invention may be applied to a signaling gateway in a video transmission system of a video network, the signaling gateway is connected to a user terminal, and the user terminal is provided with a video decoding internet browser IE plug-in;

the signaling gateway can be a video networking signaling gateway meeting GB/T28181, and the video decoding IE plug-in is a multi-channel decoding IE plug-in which can decode and play a plurality of video data simultaneously. The user terminal may be installed with an IE plug-in for decoding the video data, then displaying a corresponding video window, and playing the decoded video data in the video window.

The embodiment of the invention specifically comprises the following steps:

step 501, obtaining mark information; the mark information comprises mark graphic information and mark configuration information;

the logo graphic information is used for determining the appearance style, picture content, character content and the like of the logo, and the logo configuration information is used for determining the display rule (display posture) of the logo in the video window.

The logo image information may include that the logo graphic information includes a logo image, and/or, a logo character. The marker image may be a still image or a moving image. The logo characters may be textual information that matches the logo image, such as: the flag character may be a name, an explanation, etc. of the flag image.

The flag configuration information may include: the azimuth position matched with the edge of the video window, the azimuth offset, the transparency and the mark size.

In an embodiment of the present invention, the signaling gateway is connected to a management terminal; the management terminal is used for acquiring the mark information, storing the mark information into a preset database and generating a mark change notice. The management terminal includes but is not limited to a mobile phone, a tablet, a personal computer, etc., and the management terminal may be adapted for video networking or internet networking.

Step 501 may include: a substep S11 of receiving the flag change notification;

the management terminal stores the flag information in the database, generates a flag change notification, and transmits the change notification to the signaling gateway.

And the signaling gateway determines that the information with the mark needs to be pushed to the video decoding IE plug-in by receiving the mark change notice.

And a substep S12 of acquiring the flag information corresponding to the flag change notification from the preset database.

The signaling gateway and the management terminal are connected with the same preset database (or database cluster), and after the sign change notice is obtained, the sign information corresponding to the change notice is obtained from the preset database.

By storing the mark information into the preset database, the signaling gateway acquires the corresponding mark information from the preset database according to the received mark change notice instead of directly sending the mark information to the signaling gateway through the management terminal, thereby reducing the communication cost between the signaling gateway and the management terminal and facilitating the management (inquiry, deletion, modification and the like) of the historical mark information.

In an embodiment of the present invention, the management terminal is configured to generate generation time information corresponding to the flag information, and store the generation time information in the preset database; the sub-step S12 may include:

a substep S121 of extracting target generation time information from the flag change notification;

and the management terminal acquires the timestamp corresponding to the current moment while acquiring the mark information, and generates time information corresponding to the mark information by adopting the timestamp. Based on the generation time information, a corresponding flag change notification is generated. The signaling gateway may extract generation time information in the flag change notification by analyzing the flag change notification, and generate the generation time information as target generation time information.

As one example, the timestamp may include year, month, day, hour, minute, second, etc. information. The management terminal acquires the flag information and uses a timestamp corresponding to the time before the point as the generation time information corresponding to the flag information.

And a substep S122 of acquiring, in the preset database, flag information corresponding to the target generation time information.

When the management terminal stores the flag information in the preset database, the management terminal stores the generation time information corresponding to the flag information in the preset database.

The signaling gateway inquires generation time information consistent with the target generation time information in a preset database, and acquires mark information corresponding to the generation time information, thereby acquiring mark information matched with the target generation time information.

In an embodiment of the present invention, the management terminal includes: a WEB front end and a WEB back end;

the WEB back end is used for generating a sign change notice corresponding to the sign information and storing the sign information into the preset database.

The management terminal can be deployed with a management platform as a WEB front end, and the management platform can collect the mark information set by a manager and send the mark information to the WEB rear end. Specifically, the management platform may be provided with a flag information setting window corresponding to the video window, and the administrator may upload flag graphic information in the configuration information window and set flag configuration information.

The manager uploads the sign graphic information to a sign information setting window, and determines the azimuth position and the azimuth offset by changing the position of the sign graphic information; determining the size of the mark by changing the size of the mark graph; the transparency is determined by changing the perspective of the logo graphic.

Because the mark information setting window corresponds to the video window, the display effect of the mark information on the mark information setting window corresponds to the display effect of the mark information on the video window, and a manager can intuitively preview the display effect of the mark information on the video window, so that the mark information can be more intuitively adjusted.

The following describes the flow of collecting the flag information by the management terminal by using an example:

referring to fig. 6, a schematic diagram of sign information acquisition in the sign display method embodiment of the present invention is shown.

And (3) taking the logo image uploaded by a manager and/or the logo characters as logo graphic information.

"LEFT", "RIGHT", "TOP", and "BOTTOM" are four azimuth positions preset in the flag information setting window, where "LEFT" denotes a position located at the center on the LEFT side of the window, "RIGHT" denotes a position located at the center on the RIGHT side of the window, "TOP" denotes a position located at the center on the upper side of the window, and "BOTTOM" denotes a position located at the center on the lower side of the window. And uploading the mark graphic information to one of the four azimuth positions by a manager, and determining the corresponding azimuth position as the azimuth position in the mark configuration information.

"-X" is shifted X pixels to the left, "+ X" is shifted X pixels to the right, "+ Y" is shifted Y pixels down, "-Y" is shifted Y pixels up. After uploading the marker graphic information, the manager shifts the marker graphic information in any one direction of up, down, left and right. The offset direction and the offset pixel number of the marker pattern information are determined as the amount of offset in the marker arrangement information.

And determining the transparency in the marker configuration information by changing the perspective rate of the uploaded marker graphic information through a manager. Therein, a default transparency of 0, i.e. no perspective effect, may be set.

And determining the size of the mark in the mark configuration information by changing the size of the uploaded mark graphic information by a manager.

Step 502, sending the flag information to the video decoding IE plug-in; and the video decoding IE plug-in is used for displaying the mark graphic information in a video window according to the mark configuration information when video data is played.

And the video decoding IE plug-in receives the mark information of the signaling gateway and displays the mark graphic information according to the mark configuration information when the video data is played so as to realize the mark displayed in the video window in real time.

Further, the video decoding IE displays the historical updated logo graphic information before receiving the new logo information. And after receiving the new mark information, the video decoding IE stops displaying the previous mark graphic information and displays the mark graphic information according to the new mark information so as to update the mark displayed in the video window in real time.

When the video decoding IE plug-in is a multi-path decoding IE plug-in, the video decoding IE plug-in can simultaneously display a plurality of video windows and play a plurality of video data. At this time, the video decoding IE shows the flag graphic information in each video window according to the flag configuration information, so as to change the flags in multiple video windows at the same time.

In one example, the management terminal may generate a time policy in which a plurality of historically generated flag change notifications are recorded, the flag change notifications in the time policy being provided with the ranking information. The management terminal sends the mark change notice in the time strategy to the signaling gateway according to the sequencing information at a certain time interval, so that the signaling gateway can also sequentially acquire mark information corresponding to the mark change notice in the time strategy at a certain time interval and push the mark information to the user terminal, so that the user terminal can dynamically display the corresponding mark according to the time strategy.

In the embodiment of the invention, after the mark information is obtained through the signaling gateway, the mark information containing the mark graphic information and the mark configuration information is sent to the user terminal, and after the video decoding IE plug-in the user terminal receives the mark information, the mark graphic information is displayed in the video window in real time according to the mark configuration information while the video data is played, so that the mark in the video window is updated under the condition that the video decoding IE is not stopped.

Referring to fig. 7, a flow chart of a logo displaying method of the present invention is shown, and the logo displaying method of the present invention may include the following steps:

OP1, the manager uploads LOGO picture (graphic sign information) to the designated position through WEB front end, and reports the storage position and LOGO display area size, display direction, position offset and LOGO transparency information to WEB rear end, so as to achieve the purpose of setting LOGO information (sign configuration information).

OP2, the WEB back end stores the received LOGO information (mark information) into DB (Database).

OP3, whenever WEB back end receives new LOGO information, it sends LOGO change notice (sign change notice) to signaling gateway to notify MSERVER (signaling gateway) that LOGO module has changed.

OP4, when MSERVER receives the message that LOGO is changed, it will get the latest LOGO information from database.

And OP5, MSERVER pushes the LOGO picture and the LOGO information to an IE plug-in (video decoding IE plug-in).

And the IE plug-in displays the LOGO picture in all video windows in the IE plug-in a specified posture according to the received LOGO information.
