Broadcast is the transmission of video and/or audio signals.
Broadcast is a term that is not part of the dictionary of the Royal Spanish Academy ( RAE ). The concept is used with reference to the transmission of video and/or audio signals .
It can be said that broadcast consists of the emission of waves in different formats, aimed at a certain audience. The process can be carried out through a radio or television antenna, a satellite or the Internet, to name a few possibilities.
Types of broadcast
Radio communication is a type of broadcast. It consists of transmitting waves through radio space. The properties of these waves depend on the frequency band used. Radio and television transmissions fall into this class of broadcast.
In the field of computing , we speak of broadcast with reference to wide or broad diffusion . In this case, information is transmitted simultaneously from a sender node to multiple receiver nodes.
Internet broadcasting is known as streaming.
The streaming
Broadcasting known as streaming is common on the Internet : a transmission of digital content that develops continuously. The user, in this way, accesses the data in parallel to its download.
This means that, as streaming broadcasting develops, the person can view and listen to the information. That is, you do not need to download all the content first, as was the case a few decades ago when the Internet was just seeing the light of day.
Satellite broadcasting
A service capable of distributing video, data or audio signals in a large previously determined area is known as direct broadcast satellite or DBS , through the use of systems specially designed for this purpose. Small diameter terminals should be used to receive the DBS signal.
Since DBS satellites are very well positioned in space, they are ideal for broadcasting information directly to users through an instant connection. On the other hand, this technology can also achieve considerable bandwidths .
Satellite broadcasting has its origins in the United States, during the 1980s. At first, the service was not very successful because the satellites used at that time were more suitable for fixed services. Currently, DBS broadcasting is used especially where cable television networks (CATV) have not been implemented on a mass level.
Broadcast Domain
A broadcast domain , which in our language is known as a broadcast domain , is the logical area of a computer network in which any node can transmit to another directly without the need for a routing device . The reason is that all devices connected to the network share the gateway address and subnet, and are on the same LAN (local area network).
In other words, the broadcast domain is an area of a computer network made up of all the computers and devices that can be reached by sending a frame to the broadcast address of the data link layer (a layer that is responsible for transferring information through a transmission circuit).
Within a subnet, the broadcast domain works with its last IP address. For segmentation, it is necessary to use routers (also called routers or routers). When a switch receives a broadcast frame , it sends it to all ports except the one through which the frame entered.
Broadcast band
Broadcast , finally, is the name of an English electronic music band founded in 1995 in Birmingham .
In 2011 , their singer Trish Keenan died as a result of complications from pneumonia. After this event, only one member of the original line-up ( James Cargill ) continued to drive the group .
