Multistandard TV Data Encoding Platform

The TES3 is a highly flexible platform which carries out encoding, insertion, reception, bridging and multiplexing of digital data in the vertical blanking interval (VBI) of any television signal. It can operate in any countries' television and AC power standards, and encode and insert data in any VBI format, making this the first world-capable VBI platform. The TES3 combines the four components necessary for VBI data transmission into one unit: communications, processing, encoding and insertion. Software modules are loaded in the factory, or remotely via the built-in modem to enable the various modes.


Communications: Multiple data ports and VBI data decoders for data input and output.
Processing: The heart of the TES3 is an Intel based computer with FLASH disk. The various modes and features of the TES3 platform are enabled by loading Norpak software modules into the TES3.
Encoding: Any VBI data format (NABTS, WST, AMOL, VITC, Line 21 Captioning, proprietary) can be encoded by the TES3, with up to eight done simultaneously.
Insertion: The TES3 will insert the encoded data formats on any combination of lines 10-25 (7-22 in 625 line systems) in any video format (NTSC, PAL, SECAM, 525 & 625 Line).
The TES3 Platform features are enabled by software modules that are loaded at the factory and changed or upgraded via the built-in modem (external modem in case of LAN units) by Norpak. The standard modules are outlined below. Non-standard modules can be created by Norpak to meet specific customer requirements.


High Speed Data Broadcast: The TES3 with the Data Broadcast module is fully compliant with the established standards for VBI data transmission including NABTS, WST and the Japanese standards, and is designed to work best with Norpak's PC card and external receivers. Features include data rates up to 230 Kbs, flexible data formats, broad addressing capability, and built-in forward error correction for data broadcasting applications. Up to four separate data streams can be multiplexed into the VBI of one TV channel.
Test Encoder: This module for manufacturers and researchers allows the TES3 to be used as a reference encoder/inserter in assembly line, test facility and development applications. A single TES3 Test Encoder can simultaneously source several different signal formats in any video format.
VBI Standards Conversion: With a conversion module installed the TES3 can, simultaneously with video standards conversion, take VBI data from one video standard and re-insert on the VBI of a different video standard.
Data Bridge: The data bridge module enables the TES3 to take selected VBI data from one channel and insert it on selected VBI lines of another channel.
Closed Captioning / ATVEF:The TES3 will encode and insert EIA608B Closed Captioning, XDS data, VChip content,ATVEF 'triggers' / URLs / WebTV, and TSID on any line in any video format.
Universal: Provides complete user control over the bit format placed in the VBI. The module allows the use of any existing waveform (EIA516 NABTS, WST, EIA608). It is ideal for testing VBI receivers or the creation of custom VBI data formats.

Data ports: Three RS232 serial ports and built-in modem or 10 base T LAN interface allow data to be accepted from several sources for encoding. Alternatively, they can serve as outputs for data received through the VBI decoders. A general-purpose bi-directional 8-bit parallel port can be used for controlling external equipment or sensing external signals. The modem is also used to remotely configure the unit in the field.
EIA608/NABTS data reception: Two EIA608B (Closed Captioning) data decoders, connected to the Program and Auxiliary video inputs, and an NABTS EIA-516 data decoder connected to the auxiliary video input allow reception of Captioning data and high speed NABTS data. With appropriate software this data can be bridged to another video output, re-inserted in another data format or re-directed to a data port / LAN.

World-standard: The TES3 is fully compatible with all country television transmission standards (NTSC, PAL, SECAM, 525 line, 625 line) and AC power standards.
Individually selectable VBI lines: Lines 10-25 for 525 line systems or lines 7-22 for 625 line systems are individually selected for insertion. Additional TES3 units can be added to encode and insert on additional lines with each TES3 using a block of 16 lines.
Master inserter: Selected VBI lines of a synchronous video signal connected to the auxiliary input can be keyed into the program video output, allowing signals such as VITS or GCR produced by other generators to be inserted by the TES3. This also allows multiple TES3 encoders to be connected in parallel to insert data into the video signal. Each encoder can encode and insert onto 16 lines of the video signal.
Video bypass: Automatic video bypass goes into effect on power failure or on detection of certain faults. Manual control is also possible using the front-panel switch. The remote control connector can also be used to switch the unit into bypass.

Multi-rate data encoding: Up to eight VBI formats can be encoded and inserted simultaneously. Encoding formats are all software controlled and are enabled with Norpak software modules. Formats supported include NABTS EIA516, WST, Line 21 Closed Captioning EIA608 and AMOL. Software modules for non-standard/proprietary formats are available.
Data is received either through RS232 serial port, modem port, LAN port or video input. The encoder is compatible with existing NABTS and Captioning software packages on the market.


386 processor: An Intel CPU provides the power and familiar operation of an IBM/PC compatible computer. It runs a ROM version of DOS 6. The ISA bus is available internally on a standard PC-type edge connector as well as on a PC104 header, allowing for future addition of other interfaces.
4 Mbytes of RAM, 1 Mbyte of FLASH memory: RAM is upgradeable to 8 or 16 Mbytes and the FLASH acts as a disk. TES3 software can be changed or upgraded by downloading software through a data port. The TES3 can be dynamically reconfigured in the field.

Additional Detailed Information:



Since its incorporation in 1972, Norpak Corporation has specialized in the development of television-based data transmission systems and interactive on-line information systems. Past interactive achievements include development of screen-phones, smart terminals and on-line systems. For data transmission using the television signal, Norpak co-developed the North American Basic Teletext Specification (NABTS), the open standard for transmission of data over the television vertical blanking interval (VBI), and built the first NABTS delivery and reception system in 1978. NABTS is now an established standard for television data transmission, and is in use by broadcasters and systems integrators in North America, Europe, South America and the Far East. Norpak also manufactures equipment that implements the well-known WST (European) and Japanese standards. Norpak is the only manufacturer in the world that offers equipment meeting all data transmission formats - both the international standards mentioned and proprietary standards such as Gemstar and Nielsen. Norpak equipment functions in any TV system in the world: DTV, HD-DTV, NTSC, PAL, SECAM, 525 line and 625 line.

We are supporters of the Advanced TV Enhancement Forum (ATVEF). Norpak encoders are ATVEF compliant and by far the most popular choice for ATVEF applications. Norpak protocols and our advanced Forward Error Correction code (FEC) form the basis of the new 'IP over VBI' Internet specification.

Since 1978, Norpak has established itself as the world leader in TV data broadcasting. Norpak has now shipped over 3,600 data transmission systems worldwide, more than all other manufacturers combined. Every major US television network now uses Norpak encoding/insertion equipment, receivers, monitoring and content control systems for their TV data transmission requirements, as do broadcasters in 42 countries. Typical applications include Internet delivery, Interactive TV, network communications, news and stock quote delivery, electronic publishing, weather radar image systems, metadata encoding and Closed Captioning.

Norpak has drawn on its twenty years of interactive and TV data broadcast experience to develop a system that combines the power of broadcast television with the huge demand for remote delivery of content. Called VBinet, the system allows for the gathering, scheduling and delivery of existing  content via the television signal directly to personal computers. The VBinet family of applications packages includes an "IP Multicast Bridge" which supports advanced multicast applications such as audio and video streaming. File Transfer and Subscription Management are also part of the VBinet family.

Norpak Corporation is a privately held company based in Kanata, Ontario, outside Ottawa.
