Description

Video system and video playing method

Technical field

The present invention relates to the field of communications, and more particularly to video surveillance and network streaming technologies in the field of communications. Background technique

Multimedia technology is a technology that integrates multiple media such as text, sound, and images. The development of mobile communication has made the combination of multimedia technology and mobile communication more and more close. With the commercialization of 3G (The Third Generation), the world's commercialization, and the rehearsal of 2.5th generation mobile communication in China, It is increasingly recognized that multimedia services featuring audio and video will become the core applications of mobile communications in the future. Multimedia, mobile multimedia, combined with mobile communications, has brought about a new form of communication, with user terminals moving from mere communication tools to a new medium that delivers content and services anytime, anywhere.

Mobile multimedia services can be divided into three categories: streaming media, multimedia messaging, and video communications. Among them, streaming media technology is a multimedia application technology developed from the Internet. The so-called streaming technology is that data is transmitted from the server to the client in an uninterrupted stream, and plays when the first packet arrives. Streaming media technology does not require the download of multimedia files, so users do not need to wait for a long time. The traditional way to do this is to download the multimedia file to the user terminal before playing it. Streaming media is a new technology that integrates communication, the Internet, etc., and can play multimedia content such as audio and video through streaming media services, and can also be on-demand, interactive, such as streaming media based on mobile video services. Mobile streaming video services implemented by technology. The flexibility of mobile streaming services and the very short latency of streaming media playback allow users to instantly watch and listen to mobile video and audio. Therefore, streaming media will become the basic form of communication on the NGN (Next Generation Network).

As a basic form of multimedia communication, streaming media has spawned many forms of multimedia communication services: conference TV/videophone, network streaming media such as Internet TV, VOD (Video On Demand, video on demand), instant messaging and more. On the other hand, video surveillance has extremely wide applications in terms of national security, social security, corporate security, residential security, and home disaster prevention and burglary. It also has great economic value. The basic working principle of the current video surveillance system is shown in Figure 1. There are multiple monitoring information collection devices distributed in different locations (such as an office building or a residential community). There are currently two types of monitoring information collection devices:

A. A device that outputs a compressed encoded video stream. In this case, the device is composed of a video input device (such as a camera) and a video compression encoder.

B. A collection device that outputs an uncompressed encoded video stream. In this case, the device is actually a video input device (such as a camera). This monitoring mode is more common in some early monitoring systems, and many of them are still in use today. The benefit is low cost, but the lack of compression affects large-scale deployment, system scale, and late data processing are difficult. In order to solve this problem, a central video compression coder is introduced in the new monitoring system, and the video stream without compression coding is uniformly compressed and encoded. The archive system archives historical monitoring data. The human monitor can browse the current surveillance video by means of the monitoring display system, or access the historical archive monitoring data through the video surveillance control and management system.

However, the inventors of the present invention have found that video surveillance is not currently a telecommunication service and has no direct relationship with telecommunication operators. At most, the telecommunication operator's network is used to carry the transmission of monitoring data. That is to say, video surveillance, as a stand-alone system, has not yet been integrated into telecom services and has become a telecom value-added service. Network streaming media also cannot provide additional services with video surveillance capabilities, gaining more users and expanding into larger markets. Summary of the invention

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be The invention is further described in detail with reference to the drawings.

In the video system of each embodiment of the present invention, a user terminal, a server that provides a media stream of network streaming media, and a server that provides monitoring of the media stream are included. The user terminal is connected to the server that provides the media stream of the network streaming media, and the server that provides the monitoring media stream is connected by a physical network, and the server that provides the media stream of the network streaming media and the server that provides the monitoring media stream support At least one of the media stream formats can be played by the user terminal.

Specifically, the video system provided by the embodiment of the present invention includes a network streaming media system and a video monitoring system. The network streaming system and the video monitoring system are collectively referred to as a media stream providing system. The network streaming media system includes a server that provides a media stream of network streaming media, and the server provides a media stream of the network streaming media system to the user terminal through a physical network connected to the user terminal; the video monitoring system includes providing monitoring media A streaming server that provides a media stream of the video surveillance system to the user terminal through a physical network connected to the user terminal. The video monitoring system may be a local video monitoring system, or a public information video monitoring system or a third party service provider video monitoring system.

The following is a detailed description of the first embodiment of the present invention. The present embodiment relates to a video system. In this embodiment, the video monitoring system is a local video monitoring system based on a local network, and the local network may be a residential area or an office building. Local area network. The server that provides the media stream of the network stream and the server that provides the monitor media stream are physically two separate servers.

Specifically, as shown in FIG. 2, the network streaming media system includes a network streaming media content source and a network streaming media wide area network, wherein the network streaming media content source includes a server that provides a media stream of the network streaming media, and provides the network flow. And a server for media streaming of the media, configured to provide, by the local network where the network streaming media wide area network and the local video monitoring system are located, the media stream of the network streaming media selected by the user terminal to the user terminal on the local network.

The local video surveillance system includes a server that provides monitoring of media streams, a monitoring data archiving system, a video surveillance control and management system. Among them, the video surveillance control and management system, Used to control and manage the local video surveillance system. A monitoring data archiving system for archiving local video surveillance data. A server for monitoring media streams is provided for generating a monitoring media stream that is available to the user terminal based on the video monitoring data obtained from the monitoring data archiving system. Specifically, the historical data of the video surveillance is saved and cataloged by the video surveillance data archiving system. The server providing the monitoring media stream is responsible for transmitting the monitored current real-time monitoring data to the user terminal on the local network, or providing the VOD service for the user terminal on the local network, and the on-demand video monitoring data is the historically archived video monitoring data.

The user terminal in this embodiment may access network streaming media related information and video monitoring related information through a unified portal webpage, or may pass an EPG (Electronic Program Guide) including network streaming media related information and video monitoring related information. Obtain.

Specifically, although the network streaming system itself has a portal web page and an EPG system (located in the network streaming media content source), the user terminal can obtain information about the channel or available on-demand content by accessing the web streaming portal web page or receiving the EPG. However, since the webpage and EPG information of the network streaming media do not contain any information about the local video surveillance data, if the user terminal passes the portal webpage of the network streaming system itself or the EPG system, the media of the required network streaming media is selected. Streams, such as movies, TV shows, etc., and which simultaneously receive the monitored media stream of the local video surveillance system, have to access the two portal web pages or receive two EPG messages for the user terminal. Therefore, the present embodiment needs to provide a local portal webpage system or a local EPG system, so that the user terminal can obtain all information about the network streaming media and the video monitoring content by accessing the unified local portal webpage or receiving the local EPG stream.

As shown in Figure 2, the video system also includes a local portal web system or a local EPG system. a local portal webpage system, configured to generate a local portal webpage including network streaming media related information and local video monitoring related information, and the user terminal selects a media stream of the network streaming media to be received by accessing the webpage, or a monitoring media of the local video monitoring system. flow. The local EPG system is configured to generate an EGP stream including network streaming media related information and local video monitoring related information, and the user terminal selects the network to be received by receiving the EPG stream. The media stream of the streaming media, or the monitoring media stream of the local video surveillance system. Of course, the video system can include both a local portal web system and a local EPG system.

The following is a description of the unified local portal page. As shown in Figure 2, the portal page can be divided into two parts:

(1) Information related to network streaming media (top half);

(2) Information related to video surveillance (lower part).

For the sake of brief illustration, the network streaming related information is only listed in two categories:

A. Channel information;

B. On-demand program information.

Similarly, for video surveillance information, there are two main categories:

A. Channel information;

B. On-demand program information.

The information related to network streaming media comes from the web streaming portal webpage. The local portal web system can generate a local portal web page containing information about the network streaming media in one of the following ways:

A. Local portal webpage refers to providing connection information to a web streaming portal webpage;

B. The local portal web page contains a copy of the web streaming portal web page.

Of course, in fact, as a complete web streaming portal page, it should contain a lot of other information, such as text news, integrated multimedia information, games and so on. The local portal web page system can also generate local portal web pages containing information related to network streaming media through other implementation means. Regardless of the channel or on-demand service, the local portal page provides a connection URL (Uniform Resource Location) to the server that provides the media stream. Based on this URL, the user terminal can request a specific media stream from the server providing the media stream.

When the user terminal attempts to access the web page of the web streaming system, it will be forced to redirection to the local portal web page. This kind of redirection has many specific implementation techniques, such as:

A. Perform the corresponding configuration in the browser built into the user terminal;

B. Through some kind of equipment as an access gateway, for example, home gateway, ADSL (Asymmetric Digital Subscriber Line, Asymmetric Digital Subscriber Line), router or BRAS (Broadband Remote Access Server).

It can be seen that after such forced redirection, the user terminal can only access the local portal webpage. The local portal web page provides a user interface that allows users to query and retrieve historical monitoring data and then recall it, which is of course a VOD service.

In addition to selecting the required local video surveillance data information and network streaming media content through the portal webpage, the EGP stream generated by the local EPG system including network streaming media related information and local video monitoring related information may be selected to be locally required. Video surveillance data information and network streaming content. Specifically, the local EPG system passes the EPG stream from the network streaming system through the local EPG system through forced redirection, and the local EPG system generates EPG information about the video monitoring data, inserts it into the EPG stream, and sends it to the user terminal, so that The EPG stream received by the user terminal contains EPG information about the video surveillance data.

The video system in this embodiment further includes a local subtitle insertion system for inserting text information of the local video surveillance system into the media stream transmitted to the user terminal. That is to say, the monitoring information can be released to the user terminal through real-time text (scrolling subtitles, etc.). For example, a surveillance video input device with a public event space or parking space is damaged. In order to let residents know the occupancy of the event site in real time, they can be notified by text.

There are many technical means to achieve the insertion of subtitles. The main three are:

A. Insert directly into the video data portion of the media stream; this implementation requires (partial) decompression of the video data and then implementation of the insertion. There are two different approaches here:

A1. Fully decompress the inserted subtitles and recompress the encoding; this way the information loss is large and the processing complexity is high; but the versatility is strong, and the video stream can be processed regardless of the compression encoding format.

A2. Partially decompressing, specifically, for compressed video, as long as partial decompression extracts DCT (Discrete Cosine Transform) coefficients, and then directly processes the coefficients, it is possible to carry out letters at arbitrary positions of the image. Insert, then partially recompress the code. The disadvantage is poor versatility and lack of a common approach to various compression coding formats.

B. Inserted into the subtitle information part carried in the media stream; usually the media stream carries text information, which can be inserted or replaced directly in the text information area.

C. Send the text information (text string, font size, color, scrolling frequency period, etc.) to the user terminal, and insert it by the user terminal. The user terminal internally converts the text into an image and superimposes it on the decoded video image for display.

It should be noted that, in the case of A and B, the media stream from the network streaming content source is forced to pass through the caption insertion system through redirection. For the C case, you don't need to do this.

It is not difficult to find that the implementation of the network streaming media service and the video surveillance is integrated, the attraction of the network streaming media service is increased, the user group of the network streaming media is further expanded, and more revenue is generated for the operator. The integration has further promoted the development of NGN and turned video surveillance into a telecommunication service, thus opening up new profit space for operators.

A second embodiment of the present invention relates to a video system. The present embodiment is substantially the same as the first embodiment except that the present embodiment adds a conversion node for the user terminal from the user terminal. The instructions are converted to instructions recognizable by the local video surveillance system for controlling the motion of the monitored video input device and controlling the motion of the monitored video input device based on the converted commands.

For example, the user terminal wants to monitor the field of view that is not the view corresponding to the current monitoring video input device. Therefore, the user terminal can send an instruction for controlling the motion of the monitoring video input device, such as rotating the monitoring video input device by 45 degrees. The conversion node converts the instructions from the user terminal into instructions recognizable by the local video surveillance system, and rotates the surveillance video input device by a 45 degree angle. The user terminal is required to obtain the required monitoring field to further meet the needs of the user.

In addition, it is worth mentioning that, because the permissions of each user terminal may be different, such as the length of the building, the security committee can view the data of all monitoring points in the community, while the ordinary residents can only view the public access space, the relevant monitoring points of the door. Happening. Therefore, you need to provide hierarchical permissions. Management and certification mechanisms. This feature can be done by a local rights management system.

The third embodiment of the present invention relates to a video system. The video monitoring system in this embodiment is a public information video monitoring system or a third party service provider video monitoring system. For convenience of description, in this embodiment, a public information video monitoring system or a third party service provider video monitoring system is collectively referred to as a network video monitoring system. Specifically, as shown in Fig. 3, the server that provides the media stream of the network streaming media and the server that provides the monitoring media stream are physically two separate servers. a server for providing media streaming of the network streaming media, located in the network streaming media system, for providing the user terminal with the media stream of the network streaming media selected by the user terminal; providing a server for monitoring the media stream, located in the network video monitoring system, And configured to provide the user terminal with the monitored media stream selected by the user terminal.

The network video surveillance system includes a server that provides monitoring of media streams, a monitoring data archiving system, a video monitoring control, and a management system. Video surveillance control and management system for controlling and managing network video surveillance systems. A monitoring data archiving system for archiving video surveillance data. A server for monitoring media streams is provided for generating a monitoring media stream provided to the user terminal based on the video monitoring data obtained from the monitoring data archiving system.

The web streaming system also includes a portal web system or an EPG system. The portal webpage system is configured to generate a webpage that includes network streaming media related information and video monitoring related information, and the user terminal selects a media stream of the network streaming media to be received or monitors the media stream by accessing the webpage. The EPG system is configured to generate an EGP stream including network streaming media related information and video monitoring related information, and the user terminal selects the media stream of the network streaming media to be received or monitors the media stream by receiving the EPG stream. The network streaming related information includes: channel information and on-demand program information; the video monitoring related information also includes: channel information and on-demand program information. Of course, the network streaming system can also include a portal page system and an EPG system.

The network streaming system further includes a second information synchronization system, and the network video monitoring system includes a first information synchronization system. The first information synchronization system is configured to send the latest information of the video monitoring information to the network streaming media system, where the second information synchronization system is configured to receive the latest information of the video monitoring information, and implement video monitoring information in the network streaming media. In the system Synchronization. a portal web page generated by a portal web system in a network streaming system, or

The EPG stream generated by the EPG system contains the latest updated video surveillance information. That is to say, through the first information synchronization system and the second information synchronization system, the latest updated video surveillance information can be reflected in the portal webpage or the EPG stream generated by the portal webpage system or the EPG system in the network streaming system. .

As a public information video surveillance system for public information services, such as China Telecom's global eye service, it is generally provided by government departments or telecom operators. Based on the network of telecom operators, network streaming media services are also based on telecom carrier networks. As a third-party service provider video surveillance system provided by a third-party service provider, since the third-party service provider may have its own network, the network of the third-party service provider needs to be connected to the network and the carrier's wide-area network. Unicom, a third-party service provider network video surveillance system has its own video surveillance control and management system, as well as a video surveillance data archiving system.

Similar to the first embodiment, the user terminal can obtain network streaming media related information and video monitoring related information by accessing the portal webpage or receiving the EPG stream, and then providing the monitoring media stream according to the URL information provided by the portal webpage or the EPG stream. The server, or the server that provides the media stream of the network stream, requests the corresponding media stream. There are also hierarchical rights management and rights-based authentication mechanisms for different user terminals. In addition, the present embodiment also includes a caption insertion system for inserting the text information of the network video monitoring system into the media stream provided by each server. The specific implementation method has been introduced in the first embodiment. This will not be repeated here.

Since there is an information synchronization system in the network streaming system, and in the network video monitoring system, there is also an information synchronization system, which synchronizes the latest update of the video monitoring information to the network streaming system through information synchronization. In this way, the portal webpage of the network streaming media system is ensured, and the EPG system and the subtitle insertion system can reflect the latest information changes of the network video monitoring system.

For example, in the network video surveillance system, historical video data that can be on-demand is newly added, which is reflected in the web streaming portal webpage and the EPG stream. Or, if a monitoring point fails and monitoring data cannot be provided temporarily, you need to stream in the network. This change is reflected in the portal webpage and the EPG stream. Similarly, when the monitoring point is unsuccessful and the normal monitoring is resumed, the portal webpage or EPG stream is also updated in time. Or, the network video surveillance system needs to publish the text message through the subtitle, and then sends the text message to be distributed to the network streaming media system through the information synchronization mechanism. The network streaming system commands its subtitle insertion system to complete the corresponding subtitle generation and insertion.

Of course, the embodiment may also include a conversion node for converting an instruction from the user terminal into an instruction recognizable by the network video monitoring system, the instruction for controlling the motion of the monitoring video input device, and based on the converted instruction Controls the motion of the monitored video input device. The user terminal can obtain the required monitoring field of view to further meet the needs of the user, and details are not described herein again.

The fusion system proposed by the present embodiment is applicable to various scenarios in daily life. For example, parents need to know their children's situation in school/kindergarten during the day, and a third-party service provider deploys network video surveillance in these places. The system distributes information to the public through the system of the network streaming service provider. Parents can browse real-time or archived videos of their children's activities by entering their own authentication and authentication information through the portal page of the web streaming media.

A fourth embodiment of the present invention relates to a video system, and the present embodiment is substantially the same as the third embodiment, except that in the third embodiment, a server that provides a media stream of network streaming media, and a monitoring media stream are provided. The server is physically two independent servers, which are respectively located in the network streaming system and the network video monitoring system. In the embodiment, the server for providing the media stream of the network streaming media and the monitoring medium are provided. The streaming server is physically a server located in the network streaming system, which is the media streaming server of the network streaming system. The server provides a monitoring media stream for the user terminal by interconnecting with the network video monitoring system, as shown in FIG.

That is to say, in the network video monitoring system, the server that provides the monitoring media stream is not set, but the real-time media stream of the video monitoring is sent to the media stream server of the network streaming system through the information synchronization mechanism, or the stored monitoring data is uploaded. To the media stream server of the network streaming system, the media stream server of the network streaming system uniformly provides the user terminal with the media stream of the network streaming media and the monitoring media stream. It should be noted that the first embodiment of the present invention provides a fusion scheme between a network streaming media system and a local video surveillance system, and the third embodiment of the present invention provides a fusion scheme of a network streaming media system and a network video surveillance system. However, in actual applications, the specific application scenario may be a mixture of the above two integration schemes, that is, both a local video surveillance system and a network video surveillance system, and details are not described herein.

Or through forced redirection, the EPG stream from the network streaming system is passed through the local video monitoring system, and the generated EPG information about the video monitoring data is inserted into the EPG stream to generate information including network streaming media and local video monitoring. The EGP stream of related information is used for the user terminal to select a media stream of the network streaming media to be played or monitor the media stream.

If the network streaming system is integrated with the public information video monitoring system or the third party service provider video monitoring system, the network streaming system in which the server for providing the media stream of the network streaming media is synchronized by the synchronization mechanism The video monitoring information generates a portal webpage and an EPG stream including network streaming media related information and newly updated video monitoring related information, and the user terminal selects a media stream of the network streaming media to be played or monitors the media stream.

Next, proceeding to step S520, the user terminal selects the media stream of the network streaming media to be played or monitors the media stream by accessing the portal webpage or receiving the EPG stream.

Next, proceeding to step S530, the user terminal connects to the providing network according to the selection result. A server that streams media streams or a server that provides a media stream for monitoring, requesting selection of a media stream to be played.

Next, proceeding to step S540, a server providing a media stream of the network streaming media, or a server providing the monitoring media stream, transmitting a corresponding media stream to the user terminal, and inserting the text information into the corresponding media stream sent to the user terminal. For example, the user terminal connects to the server for providing the monitoring media stream according to the selection result, and requests to play the corresponding monitoring media stream, and the server for providing the monitoring media stream sends the requested monitoring media stream to the user terminal. And by inserting text information related to the video surveillance system into the media stream, the monitoring information is released to the user terminal.

Since the embodiment implements the convergence of the network streaming media service and the video monitoring system, the attraction of the network streaming media service is increased, the user group of the network streaming media is further expanded, and more revenue is generated for the operator, which promotes the NGN. development of.
