As we are entering broadband convergence network, business customers¡¯ demands for video service over IP are dramatically growing beyond IP based voice and data communication. AddPac introduces the most technologically advanced IP based remote video lecture system that fully integrates video, audio and data applications over the internet and broadband networks. AddPac VLPP(Video Lecture Provision Platform) next generation remote video lecture solution for distance education features centralized high performance video broadcasting server, audio MCU(Multipoint Conferencing Unit) and video monitoring system, which can be connected to various video broadcasting terminals for lecturers and students at multiple remote sites to conduct interactive video lecture.
Totally Integrated Remote Lecture Solution Achieved by High Performance Hardware Platform
The components of AddPac AP-VLPP(Video Lecture Provision Platform) remote lecture solution consists of AP5850, AP5840 video broadcasting server and AP-VG700 video gateway along with optional components such as AP-VR1000 video service router and AP-VP300 video phone terminal. AddPac IP video lecture solution has capabilities to deliver high quality video stream to multiple remote sites in real-time by leveraging high performance DSP hardware codec, real-time OS(APOS) combined with embedded hardwares.
Real-Time Live Video Lecture System for Distance Education
AP-VLPP is an ideal solution for the real-time live video lecture service over IP based network, providing outstanding performance and stability for high quality video from remote locations. AP5850, AP-VG700, AP-MC1000 MCU(loaded with voice MCU module) are designed on the foundation of the hardware codecs and the high performance RISC CPU embedded system which is well-suited to real-time high quality video transmission. The latest codecs such as MPEG-4, H.263, H.264 which are used for video compressing ensures vivid video quality even in converged network by utilizing AddPac¡¯s advanced QoS algorithm and error concealment technology. This system supports maximum 30 fps based on the MPEG-4 and it is capable of controlling frame rate and bit rate according to network availability.
A Cutting-Edge Solution : Broadcasting from Terminals
In the same manner of AddPac's IP voice broadcasting solution's prominent feature of broadcasting from a remote terminal, AddPac's AP-VLPP solution enables audio and video signals to be broadcasted from terminal to terminal as well as from server to terminal at the same time. It's because the terminal equipment support not only decoding function but also high performance encoding function. This essential feature enables educators to conduct lectures wherever terminals are located beyond the limitation of available locations.
Audio MCU and Real-Time Monitoring of Remote Listener Site
The systems for remote lectures and meetings should be fully interactive in real-time. Q&A between the lecturer and the students also has to be audible concurrently by all participants at multiple locations. With AddPac VLPP solution, this functionality is realized by AP-MC1000 which offers multipoint audio MCU features. Moreover, a teacher can have the visual of students at remote sites while conducting lectures. In addition, AP-VG700(type A) video gateway provides the encoder feature and has the external camera interface. AP-VR2000 offers the video displayer function which visualizes multiple video streams from the remote locations.
Multicasting and Advanced QoS
AddPac's AP5850, AP5840 broadcasting server not only provides services such as IGMP multicast protocol, advanced QoS(Quality of Service) and error concealment for the IP broadcasting environment but also offers advanced features such as VRRP(Virtual Router Redundancy Protocol) for load balancing and system failure prevent. It is well prepared for various situations occurring in unstable network quality.
AP-MC1000 is a next generation MCU(Multipoint Conferencing Unit) which is a
hardware type, state-of-the-art equipment for multipoint video conferencing
and real-time collaborative IP communications over any IP network. It is a
central processing solution which provides a wide variety of features such
