Most conceptions that are wedding-related are born nine months later.

But the baby that came from Will Smith and Barb Katora-Jarosinski's Dec. 2007 wedding was conceived by her nephew, Spike Katora, and was born in April, 15 months later.

The baby was Vivo, a new company that allows people to broadcast their events live over the Internet.

The problem that needed to be solved for the wedding was that Mr. Smith's parents, who were celebrating their 65th wedding anniversary at their home in Winnsboro, La., were elderly and unable to be on hand for the nuptials in Pittsburgh. Even though they couldn't be here, they wanted to witness the ceremony.

At the same time, no one wanted a Web site where anyone could just stumble across it and watch the wedding.

Being computer savvy, Mr. Katora, 29, who studied at Carnegie Mellon University and lives on the South Side, came up with a solution.

"I put together a tool kit in a couple of months that had a chat component," he said. What that means to the rest of us is that he created a system by which the couple could send video across the Internet live, and the groom's parents could even send back comments while watching.

And it wasn't just the parents of the groom who watched. Mr. Smith's sister, Nancy, witnessed the Oakmont wedding from her home in Miami, and a cousin in New Orleans also was in virtual attendance.

Mr. Katora's system had two cameras so the viewers could toggle back and forth between close-ups and a wider view of the whole church and reception. Kind of like C-Span without the editor to pick the camera shots.

Mr. Katora sat down with Paul Fireman, 45, of Squirrel Hill, and they talked about the uses for the system.

At first Mr. Fireman, who owns Fireman Creative, a marketing and advertising firm in the South Side, thought it would be perfect for Harper Collins for authors to put their book tours on the Web, but then they thought it could be bigger.

That's when Chris Szymansky, 23, of Oakland, got involved and the three of them put together a whole new concept, using a Web site as the portal for the Webcasting system.

As of April 25, consumers can go to Best Buy and for $99 buy an adapter that will allow any video camera, cable or analog, to link into a computer to stream a telecast over the Internet live. Consumers need a camera, a computer and a broadband Internet connection for the system to work.

Vivo also has joined Alpha Lab, an incubator for startup companies, to help develop their idea and move the company forward.

The way the Vivo system works, in nontech speak, is: You plug the video camera into the Vivo device that plugs into a computer. Then, Vivo guides you through how to set up the Webcast. On the viewers' end, they can tune in and watch, and even make comments to the person running the Webcast. That means if it's a question and answer session, people can ask questions. The cable contraption, which is being manufactured in Oakmont, comes with an activation card, and the company charges by the amount of usage; so if three people watch a Webcast, it is cheaper than if 3,000 people watch.

Generally, Mr. Fireman said, a wedding would cost less than $10 to Webcast. "The beauty of this whole application is it connects a lot of technologies together," he said.

"The whole entire team is Pittsburgh-based. It's not something we outsourced," said Mr. Szymansky, who did most of the Web site programming.

The fledgling company has submitted a proposal to Webcast Pittsburgh City Council meetings.

In an upcoming version, the company is working on creating a wireless adapter that will attach to the camera so it no longer has to be attached to a computer.

While the men were able to create the hardware and the software, one of the tougher aspects of the business was to name it.

The first version of the name was X-Stream, but they were at an electronics show in Las Vegas and saw everything was named X-something, even a product from the U.S. Postal Service.

As Mr. Fireman said, if the post office has grabbed a concept, it is overused.

Then they came up with Vivo, which can mean video-in video-out or "alive" in Spanish.

So they had a name, a product, and now they even have customers.

Joe Manich's daughter, Paulee, had her Bat Mitzvah in Squirrel Hill on May 23, and Mr. Manich wanted his relatives in Puerto Rico to be able to watch.

Mr. Manich, the president of the men's group at Temple Sinai, knew Mr. Fireman, and the two men decided to use Vivo to make that possible.

"It was good," Mr. Manich, of Mt. Lebanon, said. "We also had friends in Florida who were able to see it."

Mr. Manich also wants to use Vivo to broadcast the services at Temple Sinai this fall during the high holidays so members of the congregation who can't be there can still take part, even typing in the names of their deceased love ones for the prayers for the dead.

"It's a great concept," he said. "And it's fairly simple."
