CDMA wireless network video
server
1) Application
The bus carrying
120 emergency ambulances, 110 public security patrol vehicle, a long-distance
bus, the long-distance freight transport, railways, stick
Mobile little boat
Passenger ships, yachts, and surface ships in operations, and surface patrols
Environment Monitoring
Water, lakes, dams, forests, islands and so on the local wiring difficulties
2) Products
CDMA network video server (figure) is a built-in CDMA 1X Wireless Internet
Module Digital Camera System, which combines video capture and real-time
compression and wireless network transmission function as one. each with its own
equipment installed local IP address of the network interface module, CDMA
network through dial-up access to dynamic IP addresses for network connectivity
and video data transmission.
CDMA network video server platform based on high-performance DSP, using embedded
system design, can be as high as 120 per second in CIF format image coding, and
support high-resolution D1 image formats, so as to realize the real-time
high-definition video monitor. CDMA network bandwidth of 153Kbps theoretical
value, but the actual use of the 80Kbps modem ~ between the majority. By CDMA
network bandwidth limitations, CIF format video transmission frame rate in 5 ~
15 between, there will be a few seconds of delay.
Features

U tsetal H.264 coding ability, which is now the latest generation of video
coding standard, with high compression Video quality, error-strong, robust,
network transmission, and other desirable characteristics.
CDMA wireless dial-up, dynamic IP Access
U use CDMA 1X wireless module, and support for DHCP PPPOE, access to dynamic IP
address.
Reliable connectivity technology
U ultra-low bit rate, VBR and CBR support, adaptive bandwidth. Unique reliable
connectivity technology, in bad conditions to protect the network video
transmission fluid.
Guarantee security communications network
U troppus classification user rights management, using data stream encryption
technology to ensure communication network security.
Reliable system performance
Using embedded structural design, built-in hardware dog to ensure the system is
stable and reliable.

Typical Applications
120 -- where mobile wireless emergency system
Traditional medical emergency process is often the center received a 120
emergency phone call for help. According where target range of conditions, and
then different configuration of the emergency equipment. But often in the course
of the EAS will encounter many problems, such as cries for help were not very
clear description of the illness Therefore, the command control center in the
deployment of resources, it is not necessarily reasonable. or ambulance
personnel to the scene for emergency patients, it will encounter unexpected
symptoms, and it can make a timely judgment.
120 Mobile Video ambulance system is targeted at such a situation was a very
effective solution. It is through the vehicle of 120 mobile video terminal
equipment, using the latest H.264 algorithm, the use of CDMA1X wireless network
to transmit high-quality images CIF format, including monitor the transmission
of real-time data synchronization. Medical personnel to remote real-time viewing
of the car and ambulance care to save patients of heart rate, pulse, respiration
and other real-time data. Emergency medical personnel will center on the
corresponding monitor data and the actual situation of the car to give guidance
to help redeploy resources.
