How to Evaluate Video Format Converter Options

For those who are not familiar with what a video format converter is, it allows you to convert a video from one format to another. Have you ever tried to open an email with a video, or watch one online and gotten a message that says you can’t watch that format? That’s when a video format converter would come in handy.

There are many schools of thought on what video converters are best. The truth is that it depends on your needs, first and foremost. The first thing to look for is what types the video or videos you have are, and what type you want to change them to. Most converters have a wide range of types that they can accept, but can often be more restrictive in the types that they will output as. There are also converters that are specific to mobile device videos if you need that.

There are quite a few free online video converters, some that even have added features such as file merging, batch conversion, and cropping frames. For the most part the free converters are simple, easy to use, but are limited on options and can take a while to upload.

If you search, you can find sites that have side-by-side comparisons of conversion software with price listings, as well as comparisons for various online free converters. The best of these sites also list every type of video input and output possibilities, as well as extra features and options.

If you need more than video conversion, there are also sites that can do the same conversion format to format for images, audio, documents, and eBooks. The key it to know what you have, and what your end goal is as far as conversion to a certain format and anything extra you might need. Pick the converter that works on all the levels you need!

How Do RF Direction Finders Work?

To understand how RF direction finders work, it helps to understand how radio works. At its most basic fundamental element, electricity has to do with currents. AC (alternating current) and DC (direct current) currents that flow back and forth, measured in cycles per second, or more commonly known as Hz. Radio waves are measured in kHz, MHz and GHz. What radio is essentially is when the back and forth goes so fast that it jumps off the wire. The lower the frequency of the current, the longer the radio wave is, and inversely, the higher the frequency the shorter the wave. When the radio waves leave the wire, certain antennas can mold how they leave. Similarly, receiving antennas are custom made to receive certain frequencies and interpret them.

An RF direction finder is made to receive radio transmissions and determine the direction of the transmitter from data received by the antennae. These can be modified to many different radio frequency bandwidths and is applicable in land, sea and air situations. This can be incorporated for homeland security, aeronautical and marine navigation, the military, RF tagging systems such as animal tracking, and as beacon homing devices for search and rescue operations, and other emergency services. Some of the older RF direction finders date back to WWII, and were used primarily to locate enemies.

RF direction finding works in two processes: 1) Receiving and characterizing the signal, by determining the signal strength (closer is going to be stronger), the direction the signal came from, and the time of arrival. 2) Processing the data, and based on the information received, calculate the location of the signal

There do exist radio direction finding (RDF) networks, which as you can imagine, make signal finding much easier and more accurate than having just one finder. There are many benefits to having system-level locating abilities and centralized processing, and having all of the networks processing together from multiple receiving sites. An example of this is the Coast Guard Rescue network (the upgraded National Response and Distress System), which monitors the emergency channels for the marines, and locates distress calls so that response teams can locate the distress site.

What is Telemetry?

Telemetry. Sound like Greek to you? As it happens, it is! Telemetry is a word derived from the Greek tele (remote) and metron (measure). It is the technology and science of transmission and measurement of data, automatically, by radio, by wire, or by other means of remote sources. For a word you may have never heard before, it’s actually got a whole boatload of uses, and dates back as far as the 1800’s!

One of the first recorded uses of telemetry goes back to 1845, and was a circuit between the Palace of the Tsar and the army headquarters. A few years later, engineers in France built weather sensors from Mont Blanc that sent real-time information to Paris. Modern-day uses cover a pretty wide range of industries. They are used to track animals in the wild that have been tagged with radio transmitters attached to them, and even to send data transmitted to weather stations from weather balloons.

The most “glamorous” use for telemetry may be the communication from Earth to outer space! Communicating with space probes, satellites, or even in spaceflight is made possible by telemetry technology. There are other more down-to-earth examples, such as motor racing; it is used to monitor data collected from a test race to be able to tune the car for maximum performance. Formula One racing has taken telemetry to the level that they can have advanced enough information to estimate lap time potentiality of a certain car, so that the driver has a goal to meet.

If you want to get even more “down to earth”, telemetry is essential to the oil and gas industry, for being able to transmit information for drilling mechanics real-time as a hole is being dug for optimization of the drilling.

Telemetry is all around us!
