You are probably already aware that data broadcasting allows the transmission of large amounts of data to literally thousands of remote locations, and that all locations receive the data simultaneously. You may also know that data broadcasting networks can be implemented through TV stations (including DTV and HDTV), radio stations, and Direct Broadcast Satellites (DBS) and even two-way VSAT networks. Regardless of the method utilized for a data broadcasting network, the reliable, accurate delivery of data is critical to the success of the network. Developing the software for the accurate delivery of data files over data broadcasting networks was once a serious stumbling block for application developers and information providers, but not anymore! It is now easier than ever to implement a data broadcasting network, thanks to a new communications program called SATXTM, which has the capability to transfer binary data files over a data broadcasting network error free! SATXTM can be utilized in applications such as - kiosks updating electronic newspapers software distribution shopping networks multi-media networks trading networks training and education point of sale information financial information networks SATXTM is designed to transfer files from a single PC to numerous remote PCs using a data broadcasting network. SATXTM can potentially be utilized to transmit data over Direct Broadcast Satellites (DBS), TV subcarriers (or VBI), radio using high speed subcarriers (or RDS/RBDS), terrestrial TV cable systems, and even some paging systems. Originally developed for use in demanding satellite communications applications, SATXTM is more robust than FEC (Forward Error Correction) protocols and can recover from multiple errors during a file transfer. SATXTM can be used to broadcast any type of binary file, for example: digital audio or video files multi-media files graphics files compressed files spreadsheet files text files database files software programs The list of applications where SATXTM can be utilized is virtually endless. Whatever your data broadcasting software needs, we can probably help. If you need assistance setting up a data broadcasting application, let us know. We can help you with hardware selection and offer custom software solutions to help you get your data broadcast network started. Why ride the "Information Highway" when you can get on board the "Information Skyway" with SATXTM ! Sincerely, Milestone Technologies Inc. =================================================================== SATXTM Detailed Specifications DATA BROADCASTING FILE TRANSFER SOFTWARE What is SATXTM? SATXTM (pronounced SAT-EX) is a communications program designed to transfer binary files over a data broadcasting network. SATXTM can be used to broadcast data over networks utilizing direct broadcast satellites (DBS) or two-way VSAT networks, radio using RDS/RBDS (Radio Broadcasting Data System) or subcarriers, and TV using subcarriers or VBI. SATXTM is designed to broadcast data files from one IBM or compatible PC to numerous remote PCs. SATXTM utilizes a unique proprietary error detection and correction protocol which analyzes the data available at the receiving PCs for errors. Now software programs, digital audio and video files, database files and of course text files can be transmitted safely over a data broadcasting network ! Summary of Major Features of SATXTM General: Easy setup and installation Be up and running in ten minutes Protocol designed especially for binary file broadcasting Built in support for 16550 UARTS for high speed applications Status screens provide up to date information on file transfer progress Support for DOS, OS/2, Windows 3.1, Windows 95 and even Windows NT File Handling: Batch file capability Transfer even large files many MB in size Data filtering options save only user specified files User specified directory to determine location of files to transmit User specified directory to determine where received files are stored Various options for handling name collisions: overwrite, reject, backup Special features for multi-tasking OS versions to facilitate inter process communications Protocol Design: Support for IP multicasts and broadcasts Serial RS-232 versions OR new IP protocols! Variable block sizes from 128 bytes to 8192 bytes Multi-megabit/sec data rates supported using IP compatible protocols Flexible protocol can be changed depending on severity of conditions SATXTM can be configured to recover from virtually all errors normally encountered Unique ThunderfileTM protocol minimizes the chances of random errors causing data loss Error Detection and Correction: Two layers of error detection 32 bit CRC for first layer error detection Second layer error detection virtually ensures all data saved is error free Logging and Error Tracking Features: Extensive error logging of all real time errors Extensive logs of all files transmitted and received Summary logs tell SATXTM performance history at a glance More than 30 specific error codes assist with troubleshooting User specified log file sizes (save only as much log data as required) Log files designed for import into database or spreadsheet for analysis Other Features: Cable detect feature to let you know if serial cable is not connected Automatic crash recovery modes, attempts saving incoming data even if PC crashes Automatic logging reports sent to host via email (requires email connection to Internet) Design Objectives: SATXTM is designed to provide every opportunity for data to be transmitted safely by having the capability to overcome severe errors and multiple errors per file transferred. SATXTM is even designed to be resistant to the effects of rain fade experienced on Ku band satellites. Equally important, SATXTM is designed to ensure that all files available at the receiving PCs (which were broadcast by SATX Transmit) are error free. SATXTM also contains an abundance of logging and error tracking information so that file management and troubleshooting can be easily performed. Typical Applications: SATXTM can potentially be applied in data broadcasting networks which utilize: Direct Broadcast Satellites (DBS) Radio using high speed subcarriers or RDS/RBDS Two-way VSAT networks MPEG2 as auxiliary data stream TV using VBI or subcarriers Paging systems that utilize eight bit data protocols Terrestrial cable systems DTV or HDTV systems Virtually any broadcast network SATXTM is designed to provide maximum control from the transmitting site, and once installed, requires little or no user intervention at the receiving locations. Limitations:SATXTM is not designed or intended to control external communication devices such as modems. This limitation can be easily overcome by running SATXTM as an external protocol from many popular communications programs. Minimum System Requirements: Serial versions of SATXTM require equipment compatible with RS- 232 serial I/O and eight bit data. IP compatible versions typically require an Ethernet or Fast Ethernet card in a PC. Versions for multi-tasking operating systems require the same minimal hardware as the OS. Please call for additional information on optimum configurations for your application. Coming Soon!Be sure to ask about new products designed to help control and manage data broadcasting networks! Call and talk to us about some of the fantastic new products we are developing, including versions further optimized for use in two-way VSAT networks, the Internet and even LANs. MTI also offers customized solutions, if needed, and consulting in the area of data broadcasting. Please call for information on pricing, licensing, and source code availability.
