Complete ATSC Packages

VTI provides complete, redundant ATSC systems for multi-channel HD & SD transmissions.

These systems typically include encoders, multiplexers, switching, monitoring, EAS, patching and even UPS's.

We also build very cost effective single channel systems.

We configure and commission what we sell.  This is a great cost savings as you will not have to bring technicians from several companies to commission their part of the package.  Compliance is verified with our Triveni StreamScope.

Large or small, we will make sure that your system is expandable, cost effective and FCC compliant.

Call VTI for a free consultation to configure a system that fits your needs and your budget.

Dynamic PSIP

We have extensive experience deploying systems on all common encoder platforms including Tandberg, Haromnic, Harris, AgileVision and General Instruments.  Your stations program information can be automatically downloaded to the GuideBuilder PSIP generator.  We can also connect to your traffic system or manually enter the information.  We also can connect to your automation system for automatic updates up to the second changes.

There are several ways to deploy your PSIP data:

In its simplest form, you have the PSIP generator output an ASI stream and combine with the local ATSC encoder.  If you are Centralcasting, you can have several ASI outputs, one for each stations transport stream.  There also is the ability to output the PSIP via IP.  This can be done locally, but it also opens up an opportunity to centralize your PSIP generator and feed several locations via a network connection from the one system.

One station group contracted with VTI to develop and deploy a system to generate PSIP for 21 stations from their corporate office using their corporate WAN.  Another group generates PSIP for seven station and delivers the data using standard phone lines.

VTI is a authorized distributor for Triveni Digital. NEW LOWER PRICES STARTING AT $10,500 FOR GUIDEBUILDER PRO.  Triveni is by far the leading manufacturer of PSIP generators. With dozens of systems installed, VTI is your source for all your PSIP needs.  Call VTI for a free consultation.

Digital PRO Channel Receivers

Many television stations currently send IFB to talent in the field during ENG situations via the PRO audio channel in their NTSC TV signal. Some stations have switched to wireless/cell phones or 2-way radio but those operations that rely on the use of the PRO channel for cueing will face a problem after the analog cut-off because there will be no more NTSC and hence no more PRO channel. Modulation Sciences, Inc. has developed technology that allows stations to send IFB via the ATSC Transport Stream (TS) in their DTV signal.

This technology places MPEG-1 encoded audio into the TS which must be assigned its own PID. The number of IFB channels available is limited only by the bandwidth the station is able to allocate for this purpose. Each MPEG-1, layer 2 data stream requires 96 kbps. Each audio channel takes 48 kbps but they must be assigned in pairs.

Once the IFB audio is in the station's TS, a receiver located in the ENG vehicle is tuned to the DTV channel, the MPEG-1 data stream is extracted and IFB or cue audio is output to the talent. This operates much like a digital version of analog PRO receivers in use today. The receiver includes LG Electronics' 6th generation DTV receiver chip set which provides significantly improved ATSC over-the-air reception.

Encoders for Digital PROceiver's

VTI can pre-configure encoders to add as many PROceiver audio channels as needed.  The audio encoding will work with your existing ATSC transport stream.  Minimal audio delay's of between 150-350ms have been measured in actual deployments of the encoders & Digital PROceivers.

EAS

Easily generate EAS alerts for all your sub-channels and automate compliance logging. The FCC now requires that all DTV broadcasters transmit National EAS messages by December 31, 2006.  This includes all channels of a multicast.  VTI has the products and knowledge to put the right package together for you. 

We work with Sage, TFT and Triilithic, so we can add to your existing system or provide new next-generation CAP ready equipment.  We have the graphic display system for both SD and HD as well as any digital conversion or audio deembedders/embedders required to complete the job.

Let us work with you to configure the components required to make sure your EAS system is in compliance with FCC regulations.  Call VTI for a free consultation.

DTV and Satellite Receivers

VTI carries a full compliment of DTV receivers from Tandberg, Videotek and Sencore.  With configurable input and output options, these receivers can work for monitoring, retransmission or satellite reception.

Typical inputs available are ASI, SMPTE-310, 8VSB, QPSK, IP & DS3.  Outputs can be decoded analog or digital video and audio, ASI or SMPTE-310.

Want to use a single digital microwave for both your digital and analog transmitters?  We can configure a unit to take ASI, IP or DS3 in, give you ASI and decoded video and audio of the service feeding your analog transmitter.

Want to create a land based STL.  We can provide the equipment necessary to send the transport stream as ASI, DS-3 or IP and decode it at the transmitter location.

VTI has many systems deployed being used as above and many other applications.  Give us a call for a free consultation and let us come up with the solution that best fits your needs.
