Description

Mobile real-time video and BCC relay system and method thereof {System and Method for real-time relay motion picture and user created content}

The present invention relates to video relay, and more particularly, to a mobile real-time video and user created content (UCC) relay system and method for relaying real-time video using a server system independent from a mobile communication company server and easy to manage and expand. will be.

In the video transmission technology used up to now, the video transmitted from the CCTV is stored in a storage space directly connected to the web server or mobile carrier server. After that, when requested by the user, access the storage space directly connected to the web server or the carrier's server to retrieve the video, or in case of a similar situation through SMS or MMS, the user's mobile phone registered in advance and alert the user's mobile phone. The image of the moment when the situation occurs is transmitted to the storage space connected to the web server or mobile carrier server. At the same time, a text or short video is sent to the registered user's mobile phone.

However, the conventional video relay method has an advantage that it is simple to implement, but it generates a difference between the time when the image is generated and the time when the image is displayed to the user. There is a problem that requires a separate relay system.

Therefore, the first technical problem to be achieved by the present invention is to relay images received from various image sources in real time, and to implement them as a single system, the system is easy to expand, easy and inexpensive maintenance and quick recovery in the event of failure It is to provide possible mobile real-time video and UCC relay system.

The second technical problem to be achieved by the present invention is to provide a mobile real-time video and UCC relay method applied to the mobile real-time video and UCC relay system.

In order to achieve the first technical problem, the present invention collects video information from an image source, and converts the collected video information to a common codec to generate a common video stream server; A video conversion server for adjusting the common video stream converted by the common codec to a screen size of a mobile phone; And a mobile front-end server that transmits the common video stream of the video conversion server to the connected mobile phone via the mobile communication company server when the mobile phone to receive the common video stream is connected, according to the video request of the connected mobile phone. To provide mobile real-time video and UCC relay system.

In order to achieve the second technical problem, the present invention collects image information from the image source, and converts the collected image information into a common codec to generate a common image stream in a video retriever server connected to the image source and the Internet. step; Receiving the common video stream from the video retriever server in a multicast manner by a video conversion server and adjusting the common video stream to a screen size of a mobile phone; And when the mobile phone intending to receive the common video stream is connected to a mobile front-end server, the mobile front-end server receives the common video stream from the video conversion server in a multicast manner, and according to the video request of the connected mobile phone. It provides a mobile real-time video and UCC relay method comprising the step of transmitting the common video stream to the connected mobile phone via a mobile communication company server.

According to the present invention, each of the conventional distributed webcam, CCTV-based security system and VOD-type video service system can be integrated together, and real-time connecting VOD content, TV home shopping video, traffic information CCTV and clients and mobile phones The service can be implemented as a single system, and in the future, it is possible to further integrate and service video contents of different characteristics so that the system can be easily expanded and the web server outside the mobile communication network by separating the storage space connected to the mobile communication server. By establishing a separate storage space in the network, it is possible to build a system that is independent of the mobile communication network, which can be easily and cheaply maintained and can be quickly recovered in the event of a failure.
