Television diffusion is an unknown field for most of the TV viewers. Most of them do not know the origin of the signal and which are the involved devices on the distribution chain, affecting the production, broadcast or customer level. Only a reduced number of TV users comprehend the meaning of the main technical specifications of each product, for example, what means a 1080p60 video resolution. Apart from that features there are also more important characteristics such as the power consumption of a device. The election of a device, in the user case a television, with an ecological consumption can save to the user an important quantity of money, for instance in the user case, on the electricity bill. In this thesis is going to be studied the video transition to high definition, analysing which devices differ from the previous transmissions, which requirements do they need and how many energy consume, discovering the variables that directly affect to the power consumption of each device of the distribution chain, from when the video is done and needs to be compressed through a standard format, until the visualisation of that video in the households. |
