The Digital Video Broadcasting (DVB) is an industry-led consortium integrated by broadcasters, manufactures, network operators, software developers and regulatory bodies, among others. It was created in order to designate technical standards for the global delivery of digital television services. DVB standards for digital television have been adopted in Europe, Middle East, Southern Africa, and Australasia. Moreover, the DVB has been adopted in Colombia and Panama as the terrestrial digital television system (DVB-T/T2). The DVB standard is a set of specifications for integrating multimedia as a unique base for information, education, business, and entertainment development. The standard describes the coding constraints that apply to the use of the MPEG 2/4 specifications in the digital television system including mandatory, main and optional enhanced services. However, launching DVB requires of agreements among broadcasters, network operators and manufacturers on setting parameters, along with government regulations. In this paper, an overview of key elements - in technical specifications - is compiled from DVB-T/T2 documents, along with actions taken in regard to the release of DVB-T/T2 in Colombia
