Service Innovation Technology (Service Innovation Technology)

The unified video platform integrates services and transmission, and is not only automatically connected once whether a single user, a private network user or a network aggregate.

The unified video platform adopts a menu type configuration table mode to replace the traditional complex application programming, can realize complex application by using very few codes, and realizes infinite new service innovation.

Networking of the video network is as follows:

the video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the network.

As shown in fig. 1, the video network is divided into an access network and a metropolitan network.

The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch or directly connected with the node server.

Therefore, the whole video network is a network structure with layered centralized control, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star and ring.

The access network part can form a unified video platform (the part in the dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform may be interconnected via metropolitan area and wide area video networking.

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 SAReserved Label 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.

Referring to fig. 5, a flowchart illustrating steps of a data processing method according to an embodiment of the present invention is shown, which may specifically include the following steps:

step 501: receiving a browsing request aiming at a non-audio/video file sent by a video networking terminal;

the terminal of the video network may include a physical terminal such as a set-top box (SetTopBox, STB), which may be called a set-top box or set-top box, and is a device for connecting a television set and an external signal source, and converting a compressed digital signal into television content and displaying the television content on the television set. Generally, the set-top box may be connected to a camera and a microphone for collecting multimedia data such as video data and audio data, and may also be connected to a television for playing multimedia data such as video data and audio data.

And the non-audio and video files can refer to office format files of non-audio and video types. Such as text files, word files, excel files, pdf files, etc.

In practical application, the video network terminal can provide a video-on-demand channel of a non-audio/video file, when a user needs to directly check the non-audio/video file in the video network, the non-audio/video file can be requested in the video network through the video-on-demand function of the video network terminal, and then the video network storage gateway can receive a browsing request aiming at the non-audio/video file, which is generated and sent by the video network terminal adopted by the user, and extract the non-audio/video file. It should be noted that the browsing request may be transmitted in an encrypted or unencrypted manner, and the internet of view storage gateway may receive the browsing request in a wireless or wired manner, such as bluetooth, a wireless cellular network, a wireless local area network, an optical fiber, a coaxial cable, etc., which is not limited in this disclosure.

In specific implementation, the browsing request for the non-audio/video file may include a case name, a classification tag, page number information, an address of a terminal of the video network, and the like of the non-audio/video file, which are used to identify information of a browsing object and the request terminal, so that the storage gateway of the video network may flexibly select the non-audio/video file according to the browsing request, and flexibly select the content specifically referred to in the non-audio/video file.

Step 502: generating one or more slice picture data corresponding to the non-audio/video file;

the one or more slice picture data may be data intercepted by the video network storage gateway for the non-audio/video file and adopting a picture type, and the intercepted one or more slice picture data may record substantial content in the non-audio/video file.

In practical application, after receiving a browsing request sent by a video network terminal, a video network storage gateway can analyze the browsing request, so as to determine a non-audio/video file which the video network terminal actually needs to request to look up. The video network storage gateway can also open the non-audio and video file through software corresponding to the non-audio and video file, and then call a screenshot tool to intercept the non-audio and video file which is required to be consulted by the video network terminal to generate one or more slice picture data. The screenshot specifications adopted by the screenshot tool can be the same, namely, between one or more pieces of slice picture data intercepted by the screenshot tool, the length pixels intercepted from each other can be the same, and the width pixels intercepted from each other can also be the same, so that the splicing operation of the slice picture data can be better carried out according to the same screenshot specifications.

It should be noted that one or more slice picture data may be in a conventional picture data format, for example, the picture data format may be a bitmap format, a jpeg format, or the like. The present invention is not particularly limited in this regard.

Step 503: determining target slice picture data from the one or more slice picture data;

in practical application, when a non-audio and video file is requested through a video network terminal, a user often needs to carefully look up and analyze a specific part of content in the non-audio and video file, and after a video network storage gateway receives a browsing request of the video network terminal for a certain non-audio and video file, target slice picture data containing the specific part of content which the user needs to look up can be selected from one or more slice picture data generated aiming at the non-audio and video file.

In specific implementation, after target slice picture data is selected for one or more slice picture data generated by a non-audio/video file, the remaining one or more slice picture data is not required to be deleted, but can be continuously stored in the video network storage gateway.

Step 504: and generating video frame data according to the target slice picture data, and sending the video frame data to the video network terminal.

The video frame data may be data in a video format that is formed by combining one frame of picture data and can be played at a certain frame rate.

In practical application, the video network storage gateway may synthesize the determined target slice picture data to obtain video frame data that can be played by the video network terminal, and then the video network storage gateway may transmit the video frame data obtained by synthesizing the target slice picture data to the video network terminal that has sent the browsing request for the non-audio/video file through the video network. Therefore, the video networking terminal is used as embedded video equipment, the video frame data can be directly played, and the requirement of a user for looking up the non-audio and video files is met.

As an example, the target slice picture data may be a bitmap, and in the process of generating video frame data, the video network storage gateway may synthesize and convert the target slice picture into a YUV420 frame format, perform encoding and compression on the YUV420 format according to an H264 mode, then push the H264 video frame according to a preset frame rate to form a video stream output, and send the video stream output to the video network terminal that requests the non-audio/video file.

In the embodiment of the invention, a browsing request aiming at a non-audio/video file sent by a video network terminal is received; generating one or more slice picture data corresponding to the non-audio/video file; determining target slice picture data from the one or more slice picture data; according to the target slice picture data, video frame data are generated and sent to the video network terminal, the video network terminal can directly look up non-audio and video files on the video network storage gateway, special transformation aiming at the video network terminal is not needed, the speed of looking up the non-audio and video files by a user is greatly improved, the use requirement of the user is met, and the use experience of the user on video network equipment is improved.

Referring to fig. 6, a flowchart illustrating steps of another data processing method according to an embodiment of the present invention is shown, which may specifically include the following steps:

step 601: receiving a browsing request aiming at a non-audio/video file sent by a video networking terminal;

in practical application, the storage gateway of the video network can receive a browsing request sent by the video network terminal aiming at various non-audio and video files, the storage gateway of the video network can analyze the non-audio and video file objects requested by the video network terminal through the browsing request, and can determine the specific file format adopted by the non-audio and video files.

Step 602: opening the non-audio/video file in a preset virtual window;

in practical application, after receiving a browsing request sent by a video network terminal, a video network storage gateway can call application software corresponding to a specific file format adopted by the non-audio/video file, and then the video network storage gateway can open the non-audio/video file requested by the video network terminal in a virtual window through the application software.

The content in the virtual window is not on the screen, but is generated into a buffer area in the memory by an API interface provided by an operating system on the video network storage gateway, and the buffer area is used for storing application software which can start various non-audio and video files. From a program perspective, a virtual window appears as a desktop, but its contents are not displayed on the screen, but rather "displayed" in a particular memory area.

Step 603: intercepting the picture displayed by the virtual window to obtain screenshot picture data;

in practical application, the video network storage gateway can call a preset screenshot tool, and screenshot is carried out on the non-audio and video file started by the application software in the virtual window until all the essential contents in the non-audio and video file are intercepted. Moreover, the video network storage gateway can obtain the position of the application software for showing the non-audio and video files through a Graphical User Interface (GUI) provided by the operating system.

In the specific implementation, when screenshot is performed, screenshot can be performed on a non-audio/video file displayed by application software according to a preset width and a preset height, a virtual keyboard instruction page down can be called to turn pages, and the screenshot can be buffered and stored, so that when a video is played, the screenshot can be spliced according to height pixels of a screen and converted into a video format, and the video format is output to a video networking terminal.

Step 604: slicing the screen capture picture data to obtain one or more sliced picture data;

in practical applications, after the screenshot picture data is obtained by capturing the picture displayed by the virtual window, the screenshot content may be further sliced according to a specific pixel height, where the specific pixel height may be an integer fraction of the resolution of the video on demand, for example: when the standard definition resolution is 1280 × 720, the pixel width of the video or image is 1280 pixels, the pixel height is fixed to 720 pixels, and the pixel height of the slice can be set to 240 pixels, which is one third of 720. Therefore, after the slice pictures are spliced and converted, the screen of the video network terminal can be covered completely.

In an embodiment of the present application, the one or more slice picture data have numbering information.

The obtaining of the one or more slice picture data may be sequentially generating one or more slice picture format files, and numbering the one or more slice picture format files, so that the video network storage gateway may select slice pictures according to the ordered numbering, for example, a series of jpeg format files, which may be numbered 0001-. It should be noted that the specific numbers are merely examples for explanation, and the numbers and the numbering method may be adjusted according to actual situations, and the present invention is not limited to this.

Step 605: acquiring screen resolution, and determining the number of slice pictures according to the screen resolution;

in practical application, after obtaining one or more slice picture data, the video network storage gateway can obtain the screen resolution of the video network terminal through a browsing request sent by the video network terminal, and then calculate the maximum number of slices that can be displayed by the video network terminal under the condition of keeping the requested video resolution unchanged according to the screen resolution of the video network terminal and the pixel height of the slices.

It should be noted that the resolution of the video on demand can adopt two resolution modes that are conventional to video networks, namely a high definition mode: 1920 × 1080p, and standard definition mode: 1280 × 720p, and most of the video network terminals in the video network can compatibly display the two conventional resolution modes, that is, when the resolution of the video on demand is the conventional resolution mode of the video network, the screen resolution of various video network terminals does not need to be detected, and 1920 pixels are directly adopted as the pixel height of the screen of the video network terminal.

Step 606: determining target slice picture data satisfying the slice picture number from the one or more slice picture data;

in practical application, after the number of slice pictures is determined according to the screen resolution, target slice picture data meeting the number of slice pictures, which is actually required to be referred by the terminal of the video network, can be selected from one or more slice picture data.

In an embodiment of the present application, step 606 may include the following sub-steps:

In practical application, when a user sends a browsing request through a video network terminal to open the non-audio/video file and the user does not specify the number of pages to be consulted, the video network storage gateway can select target slice picture data meeting the number of slice pictures from the beginning part of the non-audio/video file, namely the target slice picture data including the initial slice picture data; when a user specifies the number of pages of a non-audio/video file to be referred for the first time through a remote control device of the video network terminal, or when playing control operations such as fast forward, fast backward, page up and down turning operations and the like are performed on the opened non-audio/video file, the video network storage gateway can respond to the playing control operations and select target slice picture data corresponding to the playing control operations such as fast forward, fast backward, page up and down turning operations and the like.

The following are examples of several of the described play control operations:

when the number of pages to be consulted is appointed through the remote control device, page number detection can be carried out on a non-audio/video file opened by application software, the content meeting the appointed number of pages to be consulted is intercepted and cut, and target slice picture data meeting the number of slice pictures is selected.

And when the play control operation of page turning is sent by the remote control device, according to the determined number of the slice pictures, selecting the slice pictures backwards according to the number of the slice pictures when the page is turned down each time. For example, when the determined number of the slice pictures is three slice pictures displayed on the current screen, three slice pictures are selected backwards according to the number information of the slice pictures when the page is turned down.

When a fast-forward play control operation is sent through a remote control device, a plurality of slice pictures which are currently displayed and a plurality of slice pictures which are to be displayed can be spliced into a large picture, the picture is captured in the large picture in a downward sliding mode according to the pixel height of a screen, wherein the downward sliding amount of pixels can be set according to the fast-forward degree, namely the higher the fast-forward degree is, the more pixels are slid downward, and then the picture with the pixel height of the screen is captured.

As shown in fig. 7, in a specific example of a data processing method, in a virtual desktop (virtual window) of an internet of view storage gateway, a corresponding word file (non-audio/video file) may be opened through a word (application software), the internet of view storage gateway captures a screenshot of a document content display portion and may automatically page until all contents in the document are captured, and then slices the screenshot, which may be specifically divided into a 0001 slice picture, a 0002 slice picture, and a 0003 slice picture … … nmn slice picture; the video network terminal can display three slice pictures at most. And then 0003 slice pictures-0005 slice pictures can be selected for slice splicing and are output as video stream push after format conversion. When the video network storage gateway receives the page turning-down control of the video network terminal, the 0006 slice picture-0008 slice picture can be selected for slice splicing and conversion output.

Step 607: and generating video frame data according to the target slice picture data, and sending the video frame data to the video network terminal.

In practical application, the video network storage gateway may synthesize the determined target slice picture data to obtain video frame data that can be played by the video network terminal, and then the video network storage gateway may transmit the video frame data obtained by synthesizing the target slice picture data to the video network terminal that has sent the browsing request for the non-audio/video file through the video network.

In an embodiment of the present application, step 607 may include the following sub-steps:

After the target slice image data meeting the slice image number is determined, the target slice image data can be synthesized in a splicing mode, so that spliced image data can be obtained. And then, carrying out format conversion on the spliced picture data, and converting the spliced picture data of the picture type into video frame data which is formed by combining one frame of picture data and can be played at a certain frame rate. For example, a target slice picture format in a bitmap and jpeg format may be converted into a frame format in YUV420, and then encoded and compressed in an H264 manner, and the H264 video frame is pushed according to a preset frame rate to form a video stream output.

In another embodiment of the present application, step 607 may further include the following sub-steps:

and circularly sending the video frame data to the video networking terminal until the next playing control operation is detected or the browsing of the non-audio/video file is stopped.

In practical application, after video frame data is generated, the H264 video frames converted from the picture format can be sent in a circulating manner according to a preset frame rate to form continuous video streams and output to the video network terminal, so as to ensure that a display picture on the video network terminal can be kept unchanged, when the video network terminal sends the video network terminal to the next play control operation or stops browsing the non-audio and video files, the fact that a user does not need to look up the non-audio and video files of a current page is indicated, namely the video network storage gateway stops sending the H264 video frames to the video network terminal in a circulating manner at this time.

It should be noted that although the H264 video frames converted from the picture format are sent in a loop according to the preset frame rate, because the video frame data is the concatenation of the still pictures, the pictures need to be changed only when the pages are turned or stopped, so a very low frame rate can be selected for playing in a loop, for example, 2-3 frames per second, which can effectively reduce the bandwidth required for loading the video stream.

In the embodiment of the invention, by receiving a browsing request aiming at a non-audio and video file sent by a video network terminal, opening the non-audio and video file in a preset virtual window, intercepting a picture displayed by the virtual window to obtain screenshot picture data, slicing the screenshot picture data to obtain one or more slice picture data, obtaining screen resolution, determining the number of slice pictures according to the screen resolution, determining target slice picture data meeting the number of the slice pictures from the one or more slice picture data, generating video frame data according to the target slice picture data, and sending the video frame data to the video network terminal, the video network terminal can directly look up the non-audio and video file on a video network storage gateway, and the video network terminal can send play control operation, the method and the system realize various looking up operations aiming at the non-audio and video files, increase the flexibility of looking up the non-audio and video files through the storage gateway of the video network and improve the use experience of users.
