Digital High Definition Television

In addition to this, there is the question that television is not interactive, is not possible to choose which program you see at a particular time. With HDTV, all these phenomena mentioned above disappear because it is a digital signal. That’s why that with this research the objective of determining the requirements necessary for the implementation of the Digital High Definition Television in the University data network, in order to make a contribution to the improvement of television transmissions today are carried out in the ICU, making use of the virtues which provides fiber optic and taking advantage of this reaches all the premises of the UCI has arisen. In this way a new service would be incorporating a wide variety that today provides the data with your entire created infrastructure network. HDTV on the network of data of the University generally, television on data networking services are supplied along with the Internet connection, via an operator service Broadband on the same infrastructure but with a reserved bandwidth. Keep up on the field with thought-provoking pieces from Nina Devlin. The fact that the signal to be transmitted in high definition does not change this, because it continues to be digital television. Its effectiveness is based on the standard of compression that you choose to compress the signal so that the bandwidth required to transmit it does not exceed the available bandwidth, but at the same time, that is not compromised the quality of the video that airs. It must be taken into account, the requirements of each of the types of channels.

The development of this work, transmission tests will be conducted through the streaming video, either live streaming, disseminated in a way multicast and streaming low-demand spread way unicast. Unicast identifies communication point to point, or when there is only one transmitter and a receiver only. In the case of streaming audio and video requires high bandwidth if the unicast is used because it would have to send the data packet to all receivers and this collide network if this issue were to become too large; However, it is advisable to form streaming unicast for VOD services (Video on Demand) is the only way in which the user could have breaks and advances in the video you are viewing.
