Over the past six or so months I’ve spent an increasingly large portion of my day talking about how to backhaul video across the public Internet. Before diving in let’s clarify what I mean by backhaul. In situations where you are shooting a game, parade, or other event in the field you have to transmit that video back to the station or whatever demarcation can get you back into your broadcast system. Traditional methods such as Satellite uplink and Microwave transmission have an extensive amount of testing, research, and development behind them; however there are two main downsides: cost and ease of use. Sat transmission prices start around $5/minute and require a trained engineer to setup and maintain. Microwave requires either an FCC license (for reliable transmissions) or unlicensed transmitter/receiver (more susceptible to interference); not to mention that you need line-of-sight or multiple hops in order to establish a connection.
Enter the Internet – prolific, speedy, and cheap. Sounds great, doesn’t it? And in many cases the Internet can prove to be an important part of a remote backhaul solution where traditional means are not available or affordable. However the Internet does not come without its own set of challenges for video transmission. In this blog post I hope to address some of the issues and strengths with using the Internet as a live video backhaul solution, as well as some of the products that I’ve tested recently and my findings from those tests.
Let’s begin with a bit of information about the Internet itself.

One of the best-attended workshops at the recent ACM-NE conference was entitled “My Network’s A Mess…Help!“ – featuring TelVue’s Chris Perry, Director of Systems Engineering.
As we push further and further into truly non-linear, tapeless workflows, networking has become increasingly important. This workshop was about proper network design and construction, products available on the market, and some basic network troubleshooting tools. Chris Perry is pretty well-known among TelVue clientele, having helped a number of stations transition to all-digital, HD, tapeless systems.
Luckily for those who couldn’t make the workshop, we have recorded it. Chris’ handout is also available here.

Google Analytics tracks video vews as “Events”

Go to the CloudCast User Manual for more detailed instructions on how to integrate a Universal Analytics account.

Chris Perry, TelVue’s Director of Systems Engineering, gets a lot of questions in the course of his work with many stations across the country. In an attempt to address some of the more frequently-asked questions, here is his Tip of the Day, on understanding SDI:
Although most of my day is spent dealing with IP video, SDI and analog video transport still plays a very important role in both control rooms and airpath distributions at many facilities. There are however a few misconceptions when it comes to terminology.
SDI is an acronym for “Serial Digital Interface.” But saying something is “SDI” doesn’t mean much more than that. There are actually subsets of standards that fall under SDI, that are standardized by SMPTE (Society of Motion Picture and Television Engineers).
Misconception #1: All “SDI” means Standard Definition, “HD-SDI” means High Definition.

The following CloudCast tip comes from Dan Silvia at ChelmsfordTV. Thanks, Dan!:
I just wanted to let you know how Chelmsford has started using our CloudCast player. We have been running into an issue of how to help our producers promote their shows without creating a ton of extra work for our staff. The solution, we realized one day, was staring us in the face with the equipment and services we already had!

When you want to broadcast a message, don’t underestimate the versatility of slide shows, especially for community bulletin boards and announcements. The most recent versions of PowerPoint and Keynote offer two very quick and user-friendly ways to convert a slide deck, with narration or sound, into a video.
