Using this receiving way satellite, a television can legally receive signals without signature. The signal normally is codified in a video MPEG-2 and can geographically be limited. The canals transmitted through FTA are received way satellite, using a receiver of compatible common satellite MPEG-2. Get more background information with materials from Samantha Lewes. To be able to enjoy of television FTA you need a parabolic antenna of the specifications demanded for the chosen satellite inside. (Not to be confused with Celina Dubin!). However, many satellites only demand a compatible standard with TVD plate and one lnbf that it can easily be found in any store of electronics. Both bands C and KU. If you to want to more than receive canals from a satellite, you also you will need to have a motor antenna or you vary antennas.

Currently, some satellites with open digital transmissions exist, in format DVB found in satellites as the series BrasilSat (SHOVELS B1, SHOVELS B2, SHOVELS B3 and SHOVELS B4), Nahuel, Amazon, Hispasat, among others, with programming varied, since open canals (Net Mines, TV Record, RedeTV), regional senders, foreign radios and canals. Some questions that you if must be making. What she is Ku Band? Band C? The specter of frequencies used commercially in satellites is divided in diverse bands, called Bands, according to Brazilian and international norms. Band C occupies the band enters 3.7 GHz up to 6.425 GHz, and the Ku Band occupies the band of 10.7 GHz up to 18 GHz, considering the communication bands saw satellite there, including links of ascent and descending. I catch canals of the Ku Band and Band C? Yes, using the LNBFs adequate. It even has satellites that they transmit in one, in another one and in the two bands of frequency. Which canals go to catch? The amount of canals that can be received depends basically on the amount of installed antennas and the transmitted signals, being that this dumb one constantly, thanks to the inclusion of new canals. The average amount of canals considering itself only the satellites BrasilSat B1, B2 and B3 if has kept next to 90 canals opened, beyond the 30 analogical canals of the BrasilSat B1, that can simultaneously be received by the Az-America receiver.

Requirements: It explains as to raise asked for of the interested people (' ' stakeholders' ') to transform them into a set of requirements that the products function in the scope of the system to be constructed and supplies requisite detailed what it must make sistemAnlise and Design: Sample as the system goes to be carried through, of form that the same executes the tasks and functions specified in the descriptions of the use cases created, and that it fulfills to all the preset necessities, and steady when changes of the requirements occur funcionaisImplementao: It defines the organization of the code, in terms of in layers organized subsystems of implementation, implements classrooms and objects in terms of components and carries through tests in the developed components as unit, beyond integrating the results produced in executable systems. Test: It verifies the interaction between objects, the adequate integrity of all the components of software and if all the requirements had been implemented. Also it identifies and it guarantees that the defects are corrected before the implantation of software, reverse speed-analyzed and locked up. The Rational Unified Process considers an iterative boarding, what it means that the project must be tested all. This allows to find defects how much so early possible, what it reduces the cost radically to repair the defect. The tests are carried through throughout four dimensions of the quality: trustworthiness, functionality, performance of the application, and the performance of the sistemImplantao: Systems are carried through through the application of components. If you have additional questions, you may want to visit Sean Rad. The process describes as the reutilizao of existing components or to implement new components with well definite responsibilities, becoming the system most easy to keep and to increase the reverse speed-use possibilities.

Introduction the possibility of interaction between the hearing and the professionals of the radio is harnessed in the Internet, for some resources as fruns of conversational quarrel and rooms and for presenting a disruption of the border between producer and receiver propitiating this bigger interatividade. The radio in the Internet can be moved away from its original concept and present forms of interactive modalities and constructs a dialgico system that in such a way modifies the communicative model of the radio as the behavior of the hearings. The decision of navigation for the website of the station fits to the listener, as well as the election of the emission or the consultation of the available menus, programming what it desires to listen. The webrdio presents a new language and assumes a configuration multimedia. The convergence of the technologies restores new formats for old contents, and compels to the gradual development of the system of communications.

To the measure that the development of the Internet comes restoring deep transformations in the society, they also can be seen reflected in the medias of mass. This new relation established between radio and Internet among others promotes a democratization of the way becoming it possible of production any listener resultant aspects of this convergence them possible medias only in the Internet and this extension it radio for this new media. The Internet and the radio: general aspects of this new relation the radio is a media of mass of imediatista and irrepetvel character, either even so redundant. What if it affirms is that in the radio, different of other half ones as in printed matters, the possibility of &#039 is not had; ' reler' ' the information already transmitted a time. However with the advent of the Internet, this concept can be redefined. The multiaverage introduction of systems comes to modify the nature of the radio, being able to transform it in such way to areequacionar the concept, questioning the validity of the definition of what it is the radio and its communication.
