Problems solved by technology

[0008] The disadvantages of the central video media server distribution method are: the range of video sources is narrow, especially for real-time video, the source data format and content are limited, and the mobility is poor, which cannot meet the mobile terminal's unique data source movement and changing needs; at the same time, The central media server has limited service capabilities and cannot effectively support the access of geographically dispersed and large-scale user groups. Even if a CDN network is used, it cannot provide effective support for real-time video streaming, and the network operation cost is relatively high.
[0009] The disadvantages of the point-to-point real-time video transmission method are: limited by the performance of terminal equipment and network bandwidth, the source mobile terminal is used as a content server, which cannot support large-scale video sharing, cannot perform large-scale real-time broadcast of video, and has a small range of use

Embodiment 1

[0054] This embodiment proposes a method for real-time sharing of mobile terminal video based on a CCN network. The source mobile terminal collects video data frames, and at the same time marks and names the encoded video data frames, encapsulates them into data packets (data packets), and sends them to the CCN node. At the same time, the video attribute information is transmitted to the target mobile terminal through the central signaling server; the target mobile terminal encapsulates the Interest packet (Interest packet) according to the received video attribute information, and sends the Interest packet to the CCN node to obtain the data packet corresponding to the Interest packet. The data packets are decoded and format converted to play locally.

[0055] Such as figure 2 It is a schematic diagram of an application scenario of real-time sharing of mobile terminal video in this embodiment, specifically including:

[0056] The source mobile terminal 200, as the source of ...

Embodiment 2

[0063] This embodiment introduces the implementation process of real-time sharing of mobile terminal video, such as image 3 To implement a flowchart, include:

[0064] Step S201: signaling initialization.

[0065] All mobile terminals establish communication connections with the central signaling server through the client signaling service module.

[0066] Wherein, the central signaling server is deployed on a certain CCN node, and interacts with the mobile terminal through the data interaction mode of the CCN protocol. In this step, the central signaling server has the functions of message and device management, and uses the periodic heartbeat monitoring mechanism to monitor the network status of the mobile terminal.

[0067] Step S202: the source mobile terminal sends a video sharing invitation message to the central signaling server, and the central signaling server forwards the request to other target mobile terminals;

[0068] After receiving the video sharing invitat...

Embodiment 3

[0081] This embodiment introduces a system for realizing real-time video sharing of mobile terminals, such as Figure 4 It is a schematic structural diagram of the system, including a source mobile terminal 1 , a CCN network service 2 and a target mobile terminal 3 . Among them, the source mobile and the target mobile run the same service, that is, a mobile terminal itself can be used as both the source mobile terminal and the target mobile terminal, and the video sharing source and video receiving end can be switched freely.

[0082] The source mobile terminal 1 includes:

[0083] The collection module 11 is used to call the device-side camera to collect the original video data;

[0084] The signaling module 13 is used for session and message transmission, that is, sending the video sharing request message and video attribute information of the source mobile terminal to the target mobile terminal;

[0085] Video engine 14 is mainly used for audio and video codec, audio and ...

Abstract

The invention brings forward a method, a system and a device for realizing mobile terminal video real-time sharing. The method comprises that: a source mobile terminal transmits video attribute information to a target mobile terminal; the video attribute information comprises video sharing identification (Call ID) and an acquisition initial data frame number (Segment No); the source mobile terminal acquires video data frames in real time, and the acquired video data frames every time are packaged into a data packet, wherein the name of the data packet is confirmed by the Call ID and the Segment No; the data packet is transmitted to a CCN node; an interest packet is generated by the target mobile terminal, the name of the interest packet is confirmed by the Call ID and the Segment No, and the interest packet is transmitted to the CCN node; and after the CCN node receives the interest packet from the target mobile terminal, the data packet matching the interest packet is acquired according to the name of the interest packet, and the acquired data packet is transmitted to the target mobile terminal. Real-time sharing of large-scale mobile terminal video data can be flexibly and efficiently supported by the method.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, system and device for realizing real-time video sharing of mobile terminals. Background technique [0002] With the popularity of smart mobile terminals and tablet computers, the wide coverage of 3G networks, and the increase of Wi-Fi hotspots, people's social and communication methods are gradually undergoing new changes. Different from traditional social networks, mobile terminals have natural contact attributes, real-name attributes, and location attributes compared to PCs, which can greatly reduce trust costs, and at the same time have strong convenience, meeting people's needs for socializing all the time and never being offline , coupled with the rapid popularization of smart terminal devices, mobile social networking is more imaginative than Internet social networking in terms of development scale and development prospects. [0003] Nevertheless, th...
