Abstract

A live broadcasting method and its system for SNG webcasting studio is an easy tool for producing teaching material and online live broadcasting. The system comprises SNG audio/video special effect equipment, a webeasting encoder, a synchronization control program for streaming audio/video, presentation files and digital whiteboard and a streaming server. Through the SNG webcasting studio, multimedia content is easily integrated. Teaching material is produced immediately and output for online broadcasting. Further, the system allows the integration of the broadcasted content from camcorder or VCR and PowerPoint files. Through Intranet or Internet, the teaching or training program is broadcasted online. The viewer only needs to logon Internet to watch the teaching or training program.

Claims

1. A live broadcasting method for SNG webcasting studio, comprising the following steps:

Step 1;

an audio/video input device for SNG special effect equipment receives audio/video signals;

Step 2;

audio/video signals received by said special effect equipment are processed and integrated to become data files through video receiving device, audio receiving device and digital special effect;

Step 3;

said SNG special effect equipment transmits completed data files to Internet broadcasting encoder through an output device;

Step 4;

said Internet broadcasting encoder is Media Producer software to process said received data files through a control program for an automated process;

Step 5;

said control program for an automated process integrates said data files by a synchronization control program for streaming audio/video, presentation files and a digital whiteboard;

Step 6;

said synchronization control program for streaming audio/video, presentation files and said digital whiteboard uses PPT, Word, HTML or digital whiteboard to integrate data files;

Step 7;

said control program for said automated process transforms said completed data files into digital media files in WMV&

WMA or MPEG4 format through compression program and transmit them to streaming server;

Step 8;

said streaming server broadcasts lively programs with the received data files to said receiving terminals;

Step 9;

said streaming server first integrates said broadcasted data files with a Script command program and Marker program at user end during live broadcasting and notes on synchronization requirement, then saves said files and automatically transforms said files into VOD (Video On Demand) digital files; and

Step 10;

at receiving end, access to Internet is available for selecting files outputted from streaming server.

2. The live broadcasting method for SNG webeasting studio of claim 1, wherein in Step 9, said streaming server integrates said broadcasted files with commands and notes at user end during live broadcasting and automatically transforms said files into VOD digital files, said commands use Script program.

3. The live broadcasting method for SNG webcasting studio of claim 1, wherein in step 9, said audio/video server integrates said broadcasted files with commands and notes at user end during live broadcasting and automatically transforms the said into VOD digital files, said commands use Marker program.

4. A SNG webcasting studio system comprising:

a SNG special effect equipment to conduct mixing and special effect on image and voice, a Media Producer software to receive media files from SNG special effect equipment and automatically transform digitized media files into WMV&

WMA digital media format through an automated process control program;

a synchronization control program for streaming audio/video, presentation files and digital whiteboard, comprising a PowerPoint Application, a digital whiteboard Application and computer monitor output interface, under a process of an automated process control program combining PPT, WORD, HTML or digital whiteboard to complete file integration; and

an streaming server, comprising a Web Server and a Media Server, receiving said synchronization control program from streaming audio/video, presentation files and digital whiteboard and providing online live broadcasting and VOD digital file saving and file management.

5. The SNG webcasting studio system of claim 4, wherein said webcasting encoder receives media data from SNG special effect equipment and transforms digitized media data into MPEG4 through an automated process control program.

6. The SNG webcasting studio system of claim 4, wherein said synchronization control program for streaming audio/video, presentation files and digital whiteboard is switchable between WORD/PPT application interfaces during real-time broadcasting and helps display hint.

7. The SNG webcasting studio system of claim 4, wherein VOD files of said synchronization control program for said streaming audio/video, presentation files and digital whiteboard are saved files for all data, on-site operation commands and notes during real-time broadcasting.

8. The SNG webcasting studio system of claim 4, wherein said SNG audio/video special effect equipment comprises:

an audio/video input device comprising an image input device and a voice input device;

a SNG special effect equipment comprising a video receiving mechanism, an audio receiving mechanism digital special effect and switch control, and receiving data from audio/video input device and integrating images and voices into digital media data; and

an output device receiving said processed data from said SNG special effect equipment and transmitting said data through an output device to webcasting encoder or saving said files.

9. The SNG audio/video special effect equipment of claim 8, wherein said audio/video input device is composed of two sets of Composite terminals and two sets of S terminals.

10. The SNG audio/video special effect equipment of claim 8, wherein said audio input device is composed of three sets of voice input terminals (Source, AUX and MIC).

11. The SNG audio/video special effect equipment of claim 8, wherein said input device is IEEEE1394 specification device.

12. The SNG audio/video special effect equipment of claim 8, wherein said output device is AV terminal and media files are saved in videotapes.

13. The SNG audio/video special effect equipment of claim 8, wherein said output device is USB interface and said media files are output to save in computer.

14. The SNG audio/video special effect equipment of claim 8, wherein said output device is IEEE1394 device and said media files are output to save in computer.
