Bi-directional Satellite solutions

SKYBLASTERTM Interactive Satellite communication system is one of the most technologically advanced VSAT systems in the world, and it has the ability to provide broadband video and data information directly to LAN or desktop office systems. Its biggest feature is that the remote station is a microcomputer as a function of receiving and launching is installed on the computer motherboard on the receiving card and the launch card completed. Combining digital Video Broadcasting with Gilat Company's unique return access method, users can enjoy the advantages of interactive communication within the intranet or desktop computer by using a computer. SKYBLASTERTM provides a superior, ip-based solution for broadband communications, including business television, corporate training, data push and Internet access, and complete independence from terrestrial communications systems.
Skyblastertm with the installation of DVB transmitter and receiver card of the computer composed of remote station together constitute a perfect combination of IP network, but also the ideal choice for IP network. Skyblastertm's main station is usually located at the user's headquarters or service provider, providing 2Mbps to 40Mbps upgradeable data pipelines, while the satellite back channel provides 38.4Kbps to 153.6Kbps information rates. Skyblastertm represents a full range of DVB solutions and provides strong support through strong network management capabilities.
The Skyblastertm feature is an open IP platform.
• Company Training
• Interactive Business TV
• Data push
• Reliable Multicast for IP
• Broadband Intranet/internet Access
First, the application
• Company Internal Training
Based on the Gilat COM Trainnettm application, SKYBLASTERTM provides a package solution for the in-house training system. Trainnettm system is equipped with broadband video decoding software and has the ability of multicast, can directly on LAN and PC for hundreds of employees online training, and also provides teachers with a complete teaching interface for real-time, online and internal interactive Training. Video, audio, and other learning materials can also be saved in an enterprise server to be accessible to employees who need it.
• Interactive Business TV
Gilat provides ip-based multicast and intranet technology to provide interactive business TV with MPEG-2 decoding quality. On a PC or TV monitor, video data streams are integrated with interactive data channels, adding new ways to communicate within the company, and can respond online to a variety of applications. This open Internet architecture guarantees the ability to support a variety of real-time audio, video, and data applications, both now and in the future. Gillaite offers a package of solutions, from the user's video signal source to the video coding server (including the IP Multicast Data layer), up to the video decoder card or software.
• Data push
SKYBLASTERTM provides an integrated end-to-end data-push solution that optimizes satellite transmission and IP multicast. Using high-end push technology with bulletin technology, you can release enterprise internal messages from various information sources and issue notices to employees and managers. Push technology can accelerate the release of information and emergency decision making. Timely unloading of sales kits can provide urgent information to the sales force, including competitive changes, new product information, price list, demo, customer information, sales incentives and success stories, and more. It has become a reality to use SKYBLASTERTM and push technology to send and configure software updates within the corporate network. Users receive several megabytes of software, enjoying automatic installation and updates. (☆ Introduction to Programming Network ☆)
• Reliable Multicast for IP
SKYBLASTERTM provides a package solution for reliable IP multicast. This scheme converts the unacknowledged protocol of IP multicast to reliable data multicast. Now, sending emergency business applications from a central point to many other locations can arrive reliably without overloading the network. For example, software updates from the server, multimedia query data and video data updates, the publication of large image files, and price information sent to the point of sale. Compared with other network structures, the satellite's inherent broadcasting capability also greatly simplifies the multicast of IP. Current Internet applications are still using inefficient point-to-point TCP/IP protocols, even when it comes to "one-to-many" communications. IP multicast solves this problem by allowing copies of individual data to be sent to all designated destinations, effectively improving the performance and efficiency of the network.
• Broadband Intranet/internet Access
By using satellite technology improved by Gillaite IP "address spoofing" technology, enterprise users can enjoy a data rate greater than 400Kbps when accessing a corporate Web server or an Internet site. LAN users can also access the global Internet via Skyblastertm gateways without having to install SKYBLAS-TERTM on the PC.
The main station provides 2mbps-40mbps high-speed exit rate, the main station is equipped with a variety of servers, including quality of service monitoring, video distribution, mass data download, Internet access and with data statistics function; The remote station is composed of a microcomputer running NT operating system, and a special board card is inserted on the microcomputer. In addition, the transmit and receive card can increase the video hard decompression as well as the conditional receiving parts. Routing and re-broadcasting is performed by a remote VSAT PC, and special customer applications can be integrated and treated with special care.
Second, the system description
The SKYBLASTERTM system is a communication network designed for two-way IP transmission, video and data multicast, which can be used for interactive internet/intranet access, mass data downloading, video broadcasting, interactive distance learning and many pc-based applications.
Skyblastertm's star-shaped network structure is ideal for communication between the corporate headquarters or the information Center and hundreds of branch offices. The SKYBLASTERTM system combines the most advanced DVB standards to ensure that complex networks are simultaneously controlled by central network management.
The SKYBLASTERTM system is composed of the following parts:
· Master Station and control equipment
· A large number of VSAT station
· Satellite channel (for link between main station and station)
· Application software
