Problems solved by technology

[0005] 1. The current multimedia system mainly adopts an all-in-one machine architecture. If it is necessary to perform conference recording and broadcasting functions in multiple meeting rooms in practice, it is necessary to deploy an all-in-one machine architecture in each meeting room separately, which has the disadvantage of high equipment cost, and Not convenient for centralized management;
[0006] 2. The current multimedia systems all use Windows-based operating systems and control platforms, which are easily attacked by virus hackers during use, have poor stability, and are not easy to maintain;
[0007] 3. The current multimedia system can only record video signals and audio signals, but cannot record VGA signals synchronously. Therefore, the application of the current multimedia conference system cannot completely record conference information and cannot meet the current needs;
[0008] 4. The current multimedia information can only be distributed through one-way streaming media, without interactivity

Embodiment 1

[0044] figure 1 It is a schematic flowchart of a multimedia communication method provided in this embodiment. Referring to the diagram, the method mainly includes the following steps:

[0045] Step 101: The signal acquisition module synchronously acquires display drawing array signals and video and audio signals, and obtains corresponding acquisition and encoding data respectively.

[0046] During video conferencing, video equipment, such as video recorders, cameras, microphones, etc., are provided in video conference rooms. There may be multiple video devices and imaging devices in each video conference room, and multiple video signal sources.

[0047] In this embodiment, each video scene is respectively provided with a signal acquisition module, and each signal acquisition module collects the audio signal, video signal, and display drawing array (Video Graphics Array, referred to as AGA) signal of the scene, and obtains each signal source respectively. The collected coded...

Embodiment 2

[0068] figure 2 For a schematic flowchart of another multimedia communication method provided in this embodiment, see figure 2 As shown, this process is relative to figure 1 The process shown differs in that:

[0069] After step 105, also include the following:

[0070] Step 201: Any client sends text information to the signal processing module.

[0071] During the process of the video conference, any client can key in text information for interactive communication on the client, and send the text information to the signal processing module in another segment of the Internet through the Internet.

[0072] Step 202: The signal processing module sends the text information to each client, and displays the text information on each client to realize interaction.

[0073] After receiving the interactive text information, the signal processing module sends the text information to corresponding clients according to a predetermined transmission path, thereby realizing information...

Embodiment 3

[0081] image 3 It is a schematic structural diagram of a multimedia communication system provided by this embodiment. see image 3 As shown, the system mainly includes: a signal acquisition module 301, a signal processing module 302, and the two modules are connected to the Internet. Its working principle is mainly as follows:

[0082] The signal collection module 301 collects the display drawing array signal and the video and audio signal at the end of the signal collection module 301, and obtains corresponding collection and coding data respectively. The signal processing module 302 receives the collected and coded data from the network, combines at least two arbitrary collected and coded data to obtain combined audio and video data, and then sends the obtained combined audio and video data to each client 303 on the Internet through the Internet.

[0083] For the detailed working principle, refer to the record in Embodiment 1, which will not be repeated here.

Abstract

The invention relates to the multimedia communication field, and discloses a multi-information combined multimedia communication method and a multi-information combined multimedia communication system. The method comprises the following steps: synchronously acquiring and displaying a graphics array signal and a video-audio signal by a signal acquiring module, as well as acquiring related acquiring coding data respectively; transmitting each acquiring coding data to a signal processing module by the signal acquiring data through the internet; receiving each acquiring coding data by the signal processing module, and randomly combining at least two acquiring coding data to obtain combined video-audio data; and then transmitting the combined video-audio data to each client by the signal processing module through the internet.

Description

technical field [0001] The present invention relates to the field of multimedia communication, in particular to a multi-information combined multimedia communication method and system. Background technique [0002] With the development of information and electronic technology, the application of multimedia equipment (projectors, video booths) is becoming more and more extensive, and the display methods in conferences, training, teaching and other scenes are becoming more and more abundant. [0003] For most enterprises, important meetings usually need to be video archived, while some traditional recording methods, such as video recorders, DV and other equipment, can only record a single video and audio signal, and cannot simultaneously record meetings displayed on-site through projectors and other equipment , Teaching content, unable to meet the needs of comprehensive recording of visual information in meetings, training, and teaching scenes, and these contents are often the...
