The speech was not broadcast directly, but was replayed from a phonograph recording made in the Tokyo Imperial Palace on either August 13 or 14, 1945. Many elements of the Imperial Japanese Army were extremely opposed to the idea that Hirohito was going to end the war, as they believed that this was dishonourable. Consequently, as many as one thousand officers and soldiers raided the Imperial palace on the evening of August 14 to destroy the recording. The rebels were confused by the layout of the Imperial palace and were unable to find the recording, which had been hidden in a pile of documents. The recording was successfully smuggled out of the palace in a laundry basket of women's underwear and broadcast the following day, although another attempt was made to stop it from being played at the radio station.
With a sufficiently sophisticated switch, it is possible to create a network in which the normal notion of a broadcast domain is strictly controlled. One implementation of this concept is termed a "private VLAN". Another implementation is possible with Linux and iptables. One helpful analogy is that by creating multiple VLANs, the number of broadcast domains increases, but the size of each broadcast domain decreases. This is because a virtual LAN (or VLAN) is technically a broadcast domain.
In its simplest form, a broadcast translator is a facility created to receive a terrestrial broadcast over the air on one frequency and rebroadcast the same (or substantially identical) signal on another frequency. These stations are used in television and radio to cover areas (such as valleys or rural villages) which are not adequately covered by a station's main signal. They can also be used to expand market coverage by duplicating programming on another band.
Broadcast audio as a rule must be as free as possible of Gaussian noise, that is to say, it must be as close to the noise floor, as is reasonably possible, considering the storage or transmission medium.
This is achieved by designating one or more "server" or "provider" nodes, either by MAC address or switch port. Broadcast frames are allowed to originate from these sources, and are sent to all other nodes. Broadcast frames from all other sources are directed only to the server/provider nodes. Traffic from other sources not destined to the server/provider nodes ("peer-to-peer" traffic) is blocked.
The result is a network based on a nominally shared transmission system; like Ethernet, but in which "client" nodes cannot communicate with each other, only with the server/provider. A common application is Internet providers. Allowing direct data link layer communication between customer nodes exposes the network to various security attacks, such as ARP spoofing. Controlling the broadcast domain in this fashion provides many of the advantages of a point-to-point network, using commodity broadcast-based hardware.
In a mobile ad hoc network (MANET), route request (RREQ) packets are usually broadcast to discover new routes. These RREQ packets may cause broadcast storms and compete over the channel with data packets. One approach to alleviate the broadcast storm problem is to inhibit some hosts from rebroadcasting to reduce the redundancy, and thus contention and collision.
Citizen broadcast journalism is a new form of technology that has allowed regular civilians to post stories they see through outlets such as Snapchat, Facebook, and Twitter. It has become a new trend that some allegedly fear will take over broadcast journalism as it is known. News companies, like Fox News, are employing citizen journalists, which is a new phenomenon among journalism.
Broadcast engineers in North America usually line up their audio gear to nominal reference level of 0 dB on a VU meter aligned to +4dBu or -20dBFs, in Europe equating to roughly +4 dBm or -18 dBFS. Peak signal levels must not exceed the nominal level by more than +10 dB.
Broadcast audio must have a good signal-to-noise ratio, where speech or music is a bare minimum of 16db above the noise of the recording or transmission system. For audio that has a much poorer signal-to-noise ratio (like cockpit voice recorders), sonic enhancement is recommended.
ESBTs. The algorithm uses pipelining by splitting the broadcast data into
Shaw Broadcast (originally CANCOM Broadcast) distributes both specialty cable channels and regular broadcast network affiliates via one of North America's largest full-service commercial signal distribution networks. It distributes affiliates of all the major Canadian commercial networks, along with several independent services.
, so the startup latency is only one half of the startup latency of the two-tree broadcast. The drawback of the ESBT broadcast is that it does not work for other values of
Broadcast safe standards for 525 lines of Standard Definition (System M, NTSC) video are:
In countries that have selected Cell Broadcast to transmit public warning messages, up to 70-85% of the population older than 12 year receive the public warning message within seconds after the government authorities have submitted the message see as an example Emergency Mobile Alert (New Zealand), Wireless Emergency Alerts (USA) and NL-Alert (Netherlands).
This limitation is since 2012 no longer present. In case a national civil defence organisation is adopting one of the Wireless Emergency Alerts standards, WEA - formerly known as CMAS in North America, EU-Alert in Europe, LAT-Alert in South America, Earthquake Tsunami Warning System in Japan, each subscriber in that country either making use of the home network or is roaming automatically makes use of the embedded Public warning Cell Broadcast feature present in every Android (operating system) and IOS mobile device.
A point of criticism in the past on Cell Broadcast was that there was no uniform user experience on all mobile devices in a country.
Broadcast safe standards for 625 lines of Standard Definition (Inaccurately referred to as PAL, a colour encoding that is usually used with such systems) video are:
== Two Tree Broadcast (23-Broadcast) ==
== Pipelined Binary Tree Broadcast == This algorithm combines Binomial Tree Broadcast and Linear Pipeline Broadcast, which makes the algorithm work well for both short and long messages. The aim is to have as many nodes work as possible while maintaining the ability to send short messages quickly. A good approach is to use Fibonacci trees for splitting up the tree, which are a good choice as a message cannot be send to both children at the same time. This results in a binary tree structure.
