Digital Television Networks

Television networks carrying television signals need to transport video and accompanying audio signals. Historically, analog television networks have played an important role. Transmission characteristics and impairments in these networks are well known. Digital television technology performs quite differently. The impairments are not related to distance as with analog transmission but depend very much on codec technology and interface specifications. Various network technologies find use in the digital television production and transmission of digital television signals. These networks allow better and easier TV production. In this paper we take a look at the digital television networks technologies. The important topics such as: network properties, quality of picture requirements, video interface design, aspects of coding and new transmission formats, will be taken into consideration. The different requirements associated with different network access levels will be defined.
