What is the .HRZ File Extension?


.HRZ File Extension Description:

The file extension HRZ is used as an SSTV file, or a Slow Scan TV file. As its name implies, Slow Scan TV is a method of transmitting pictures using low frequency. The low frequency transmission coincides with the transmission of signal over a narrow bandwidth, around 2.5 kHz - 3 kHz wide. To be able to fit into this narrow bandwidth, it is required that a low frequency horizontal and vertical scanning be used, ideally at 16.6Hz. Because of these requirements, only still pictures can be transmitted often within eight seconds up to two minutes.

Transmission signals are sent over voice frequencies. With the advancement of technology, digital transmission has been incorporated. Using digital techniques and recent computer systems, the scanning frequency can be increased up to 128 lines. Because of this, the transmission of still pictures is not restricted to monochrome colors; colored pictures can now be transmitted.

Files having the HRZ file extension as used by Slow Scan TV are recent additions in the advancement of this technology. SSTV uses analog frequency modulation. A binary code is usually added at the start of the analog wave, to provide a set of instructions to the demodulator. The use of computers comes in when demodulation of the received signals is done through software, with, or without the accompaniment of hardware. The HRZ file extension is often involved in the demodulation process. Since the SSTV are transmitted over voice frequency, the received signals are audio sound which when unprocessed, resembles a series of high pitched continuous clicking.

Today, personal computers are equipped with both receiving, and transmitting capabilities of the SSTV signal. These unique transceivers are especially beneficial first, because of its large memory for receiving and transmitting signals, and may employ the HRZ file extension in its file use. Secondly, it is because of the display facilities used by personal computers, which make it easy in displaying colored and still images from modulated signals.
