Trend 1: Fusion of software and hardware video conferencing
In order to meet the needs of enterprise users who can access the conference anytime and anywhere, and take into account the high-definition and virtual reality venues, software video conferencing and hardware video conferencing (remote presentation) will merge. The development of a converged conference will go through three phases.
The first phase: realizes the interconnection and intercommunication of hardware video conferencing, software video conferencing, and UC (Unified Communication), and initially realizes ordinary dian, IP phone, UC soft terminal, Web client, mobile terminal, and telepresence conference terminal. Also access the conference. The solution not only preserves the experience of two different types of conferences, but also enables multiple terminals to participate in the conference at the same time.
If the enterprise needs to open a very important formal meeting, the branch office can use the telepresence conference terminal to participate in the conference. The traveling staff can remotely access the software video conferencing system through the PC (UC soft terminal or web client), and then pass the software and hardware. The cascade of video conferences is connected to the telepresence venue.
The second stage: unified site control and conference management from the platform architecture. Realize the unification of H.323/MCU-based hardware video conferencing and SIP/HTTP-based software desktop video conferencing at the signaling control level, and control the access of various terminals through the SIP protocol and the unified AS (application server). Class media resources are managed; unified network management is used to integrate the overall network device management of the conference system, and a unified management portal is provided for service configuration and conference reservation to provide a unified portal and conference management experience......
In the third stage, the integration of various media resource servers is realized, and a unified media integrated aggregation and transcoding center is provided. The media center pushes the code stream of the appropriate coding format to the multimedia terminal according to the capability of the terminal, thereby realizing a multi-screen consistent experience. Through the common platform of multimedia capabilities, audio, video, text and data can be uniformly deployed and shared, and audio and video engines can be shared between various terminals and media centers, and the multiplexing capability can be improved. Finally, the completion of various conference terminals and conference systems can be completed. Fusion.
Trend 2: Low bandwidth and high quality audio and video
With the development of speech codec technology, conference speech will develop to broadband multi-channel: 8KHz mono Ã 22KHz stereo Ã 22KHz multi-channel Ã virtual sound field. At the same time, when the desktop terminal accesses the conference from the public network, it can adopt an intelligent algorithm, and according to the network transmission quality, combined with the network model, a Z-good coding and transmission scheme adapted to the current network is provided, so as to ensure that when the network changes, it can still Provide users with a good business experience. For example, when the network is degraded, the smart uses low-bandwidth voice codec to ensure normal voice calls; when the network improves, the broadband codec is used to enhance the user experience. More importantly, voice quality can be smoothly changed during this change.
Similarly, video media will also evolve from standard definition to high-definition, moving toward higher resolution and better fluency: codec technology upgrades from H.263, H.264 to H.264HP and H.265, capable of upgrading The 1080P video effect is first implemented in the 1M bandwidth case.
Trend 3: Sharing and Collaboration
The continuous development of modern enterprises, the cross-regional virtual team has become the norm, and the conference has shifted from communication-centered to sharing and collaboration. Traditional hardware video conferencing realizes the communication of voice and video information. Software video conferencing introduces the ability of data collaboration based on audio and video, and can provide collaboration functions such as screen sharing, document sharing, electronic whiteboard, text chat, and electronic voting. There is no such thing as the dissemination, classification, search, many-to-many asynchronous sharing and collaboration of conference content, and it is necessary to further expand its collaboration capabilities.
In combination with the information dissemination means of social networks, the "conference space" will be introduced into the conference system to realize the dissemination and sharing of conference content. Before the conference, the conference organizer or the participants can upload the conference materials and send the conference notice to the participants to know in advance. The theme of the conference, based on the permissions, can modify the document, upload a new version, and automatically update the participant with a document update;
In the meeting, the system directly uses the conference materials uploaded in advance to reduce the time for document sharing in the conference, and can record the conference content in real time and upload it to the â€œconference spaceâ€, which can provide live broadcast of the conference for the public conference;
After the meeting, the conference materials, conference videos and meeting minutes can be classified, on-demand and downloaded, and discussion space is provided for discussion and communication. Therefore, the information dissemination is realized on the basis of information communication, and the sharing and collaboration of the enterprise virtual team is realized.
Trend 4: Simple and fast meeting experience
With the application of various new technologies, the conference function becomes more and more powerful, but the conference business experience provided to users should be more convenient and faster. The use of conference services mainly includes conference convening and conference joining two scenarios. In the call meeting, in addition to being able to log in to the portal for meeting reservations, it can also be integrated with UC and other mainstream enterprise application software, and can be initiated by UC soft terminal, Outlook, Notes, Office, enterprise OA or other application software client. The meeting was convened to make the meeting habits consistent with the use of other office software. For example, when the user receives an email and wants to directly convene a conference to discuss the topic, he can directly click the button in the email to initiate the conference. The system automatically uses the email subject as the conference theme and uses the email content as the conference material. The sender and all recipients are appointed as meeting members and make meeting appointments to achieve emotionally aware meeting calls.
In addition, you can create meeting groups and meeting templates to initiate a meeting with the default configuration. After the conference is successfully scheduled, the system automatically creates a â€œconference spaceâ€ and sends a conference notification to the participants, which can be email, SMS or other means. After receiving the notice of the meeting, the participant can click on the link in Outlook to type a meeting, or click on the meeting list in the UC soft terminal to type a meeting. When the user cannot access through the PC, the system can also reply to the message by the system. Outside call ji voice into the meeting.
During the conference, participants can implement one-click forwarding in multiple desktop terminals. For example, there is currently a user who is accessing a remote training through a PC. At this time, the user wants to pour a glass of water in the pantry, and can transfer the sound of the field to his hand by a one-touch transfer function, and then can hold the hand. I went to the tea room and poured water. After returning to the seat, I will transfer the call back to the PC so that no training content will be missed.
For the user, whether it is to convene a meeting or attend a meeting, the user can have a simple meeting experience.
Trend 5: Mobile Terminal Access (BYOD)
With the development of mobile Internet and the popularity of mobile broadband, there are more and more mobile devices (smart phones, tablets) around the employees, and they have formed stable usage habits. They are eager to use their own familiar self. Have the flexibility to participate in meetings at any time and any place.
On the one hand, this can not only improve efficiency and reduce enterprise costs; on the other hand, it can significantly reduce energy consumption of enterprises and improve the overall efficiency of business operations.
Converged conferences will also support the participation of all kinds of mobile terminals. In addition to providing audio and video communication, it can also provide functions such as screen sharing, electronic whiteboard collaboration and message chat, which is convenient for employees in airports, hotels, homes, etc. Join the meeting.
The interconnection of conference systems is a new industry hotspot, which will greatly enhance the use of enterprise conference systems. Collaboration capabilities anytime and anywhere will also inject new vitality into the constantly changing business forms and help enterprises gain broader development space. More agile market competitiveness.
