Solution Description:
Multimedia Recording & Casting System adopts the distributed
architecture and includes Multimedia Recording & Casting
Server and encoders. The figure above shows the typical networking
mode in the videoconference system. The encoders, located in
the front end of the system, are connected to the videoconference
terminal. The encoders are responsible for collecting video
and audio and VGA (double current) signals in the videoconference
system. The encoders encode the collected signals and send the
encoded signals to the Multimedia Recording & Casting Server
in the background via the IP network. The Multimedia Recording
& Casting Server can perform synchronously integrated recording,
live broadcast and play on demand on the received video and
audio signals and VGA signals.
The encoders may be categorized into the following two types
according to the types of signals that the encoders can process:
(1) Video and audio signal encoder series: including AV Encoder
and High-definition Encoder;
(2)VGA signal encoder series: including VGA Encoder and High-definition
Encoder;
The High-definition Encoder may be used for encoding video and
audio signals or VGA signals. Users may select the combination
of encoders according to the type of videoconference system.
For example, for the recording of a common videoconference system,
user may select AV Encoder + VGA Encoder;
for the recording of high definition videoconference system,
users may select High-definition Encoder
+ VGA Encoder.
Advantages and
Features:
1. Can be used together with videoconference
system or individually！！With extensive use and powerful capabilities
For the users deploying videoconference system, most of routine
conferences are held locally, and the traditional videoconference
systems are used only at the remote videoconference, and thus
the expensive costs on the system only bring about low utilization
ratio, with less user investment effect. Multimedia Recording
& Casting System collects signals from the signal source
directly and can be used together with videoconference system
or for the recording& playing of local conferences, with
more extensive using range and higher utilization ratio.
2. Low coupling design, not occupying
any MCU resource and no disturbances on the operating status
of the videoconference！！Enjoy using it without any worry!
Generally, when performing videoconference system planning,
the overall system consists of core system and peripheral system.
Taking the system stability and security into account, the peripheral
system shall try to reduce the degree of coupling with the core
system, thus insolating the faults. The recording& playing
product belongs to peripheral system of the videoconference
system. Multimedia Recording & Casting System employs the
low coupling design between the videoconference core systems
(MCU and terminal), not occupying any MCU resource, and the
operating status of the videoconference system will not be disturbed
even if the multimedia recording& playing system is faulty.
3. Recording of multiple signals in a
combined manner！！Record comprehensively without loss of any
detail.
It supports recording of AV and VGA signals in any combined
mode, such as AVX1+VGAX1, AVX2+VGAX1, And AVX1+VGAX2, and can
satisfy the requirements of synchronous recording of local images,
remote images and double current contents in the videoconference.
Thus it can record the live situation of videoconference in
an all-round manner.
It supports recording of six AV and VGA signals maximally in
any combined mode, thus meeting the requirements in more applications.
4. High-definition！！Present Every Detail,
and challenge the visual limit.
The system supports recording of high definition signal of 720P/1080i.
In combination with the use of high definition videoconference
system, the system can record the field situation of conferences
and instructions in a more clear and authentic manner, thus
giving audiences wonderful visual effects.
5. Distributed！！Easy-to-deploy and flexible
expansion
The system is designed in a distributed architecture based on
IP network and implements splitting between signal collection
and signal processing, making the system deployment and expansion
more flexible. The encoder used for signal collection in the
foreground can be installed in any one conference room, while
the Multimedia Recording & Casting Server in the background
can be installed in the equipment room. IP network-based communications
are established between the foreground and the background, thus
meeting the needs of recoding of conferences held in any one
conference room.
6. Embedded！Stable, reliable, and free
from virus attack.
The system adopts embedded operating system and private hardware
platform designed in non-PC architecture, featuring stability
and reliability, protection from virus and Hacker attack and
convenient maintenance and management.
7. Powerful VGA signal recording capacity！！Make
the processing of VGA signal freer.
This feature is reflected in the following three aspects:
(1) Flexible recording mode: It supports recording in hardware
mode;
(2) High definition: It supports ordinary mode of 4: 3 and wide
screen mode of 16: 9/16:10, thus satisfying the recording needs
of various resolutions ranging from 640X480 to 1280X1024;
(3) High frame rate: The frame rate ranges between 1 and 30
frames per second, thus satisfying the requirements of recording
and casting of the dynamic video on a computer screen.
8. Support cascading and network storage！！Large
scale and capacity.
The system supports multilevel cascading between Multimedia
Recording & Casting Servers, and recording and live broadcast
can be performed under cascading condition. In the meantime,
it supports network storage under iSCSI protocol. All these
features strongly guarantee the large-scale and large-capacity
applications of the system.
9. Client interaction and online user
management function！！Break the tradition and the stream media
is no long unidirectional, making remote training easier.
Traditional stream media systems are all unidirectional, but
Multimedia Recording & Casting System creatively provides
text interactive functions at the client end so that the user
can chat while watching and propose questions timely. The introduction
of interactive function can better satisfy the needs of instruction,
training and lecturing. Meanwhile, the system provides abundant
online user management functions such as online user statistics,
roll calling and so on. It can easily organize remote training
through Multimedia Recording & Casting System even without
videoconference.
10. Independent R&D and sustainable
improvement capabilities！！Satisfy users¨ individualized requirements.
The Multimedia Recording & Casting System is developed independently
by Shenzhen Reach Software Technology Co., Ltd. The Company
has a lot of software and hardware intellectual property rights
and patents and powerful R&D capability, thus ensuring sustainable
improvement of its products and satisfying users¨ individualized
requirements.
Values of Multimedia Recording & Casting System for videoconference
system users:
