edastused

Edastus refers to the transmission of signals from a source to receivers, covering radio, television and other forms of content delivery. In Estonian, the plural edastused denotes broadcasts or transmissions carried out by broadcasters, telecommunication operators or content providers, including live and on-demand delivery.

Forms and contexts include traditional over-the-air radio and television, satellite and cable distribution, as well as internet-based streaming. Live edastus happens in real time; on-demand edastus allows listeners or viewers to access pre-recorded content at a later time.

Technologies in broadcasting have transitioned from analog to digital, enabling higher efficiency and new services. Digital terrestrial television (DVB-T/T2), digital radio, satellite, cable, and IP-based delivery are common modalities. Internet streaming uses protocols and content delivery networks, with unicast, multicast or other delivery models; latency and bandwidth are key considerations.

Regulatory framework and rights influence edastused as well. Spectrum management, licensing and public service obligations affect what can be transmitted and to whom. Intellectual property rights apply to transmitted content, and enforcement varies by country.

In media studies and industry discourse, edastus is a central concept in the distribution of audio-visual content and data over heterogeneous networks, shaping audience access, content licensing, and the economics of media delivery.
