Transmitting files over satellite tv

Knapsack Datacasting Technology

Delivering any digital content through common Satellite TV beyond borders

Overcoming Communication Barriers

Overcoming barriers and reaching all corners of the world, NetFreedom Pioneers uses its Knapsack Datacasting Technology brings rich digital content directly to the user. Airing from existing satellite networks and accessed through inexpensive and off-the-shelf Free-to-air satellite receivers, individuals can download entire encoded libraries of media in a variety of formats without regard to natural or man-made obstacles.

Bridging the Digital Divide

The unprecedented access to information brought about by the internet has elevated the individual and provided billions with a better, more connected life. However, untold more are left on the other end of a growing divide, disconnected from all the internet has to offer as a result of poverty, remote geography, or censorship. We envision our Knapsack Datacasting Technology as the bridge across this digital divide. Cheaply, freely, and securely, communities that were previously denied access will now have the available means to reap the benefits from continuously-expanding libraries of digital information.

Global Coverage

Using existing satellite networks, and with the flexibility to use digital terrestrial channels as well, NFP’s Knapsack datacasting technology allows for truly continental coverage. Everyone under the umbrella of these existing ranges can gain access to rich information, even if they would normally be outside the reach of more traditional information and communications infrastructure. 


Public Use, No Footprint

NFP’s patented technology is secure and anonymous, using only one-way communication. The content you decide to view cannot be monitored, and your personal information is never gathered nor shared.

Simple to Deploy, Easy to Use

For the user, no additional hardware is needed beyond a common Free-to-air (FTA) satellite system. The technology is designed to be quick to set up, and exceptionally easy to learn and use. Since the data can be stored offline in common usb drives, this allows for poor and remote communities to share content so long as a single dish and receiver is present.

“I think the idea behind Toosheh (‘Knapsack’) is brilliant. Using this method you can download Tor Browser, our video explaining Tor, and Tails within minutes—something that’s currently impossible with the internet speed in Iran.”

How It Works

Like a backpack on a TV stream

Knapsack technology makes transferring non-video data over TV streams possible. Data is packetized into TS standard packets, uploaded onto a server, broadcasting via existing satellites, and then recorded and decoded at the user end.

Format-agnostic Content

Knapsack datacasting technology is able to transmit information in a variety of forms, not just video. Whether it’s PDF, JPEG, HTML, MP3, or another format, data is collected as users record the broadcast satellite channel. A simple USB drive  connected to the satellite set-top box stores the information, allowing the user to later connect the drive to a smartphone or computer and view the content in its original form using our decoding and file viewer software.
