Digital Television Transition in Chile
The shift from analog to digital terrestrial television (DTTV) represents a significant technological leap for broadcasting in Chile. This transition involves updating the legal frameworks and technical standards used to transmit television signals, ensuring higher picture quality and more efficient use of the radio frequency spectrum.
The Path to a National Standard
The formal process began in late October 2008, when the President submitted a bill to Congress to establish the legal framework for DTTV broadcasting. While this bill laid the groundwork for the transition, it did not initially specify which technical standard the country would adopt.
After a period of deliberation, Chile announced its decision on September 14, 2009, to adopt the ISDB-T International standard. This Japanese/Brazilian system, utilizing MPEG-4 (a high-efficiency video compression standard), aligned Chile with other regional neighbors including Brazil, Argentina, and Peru.
Implementation and Timelines
The transition to digital broadcasting has seen several adjustments in its timeline. Originally, the analog switchoff—the process of shutting down old analog signals in favor of digital ones—was scheduled for 2019. However, as of 2021, a revised schedule has been established, pushing the target date to 2024.
Before the national standard was finalized, several broadcasters conducted independent tests. TVN, the state-owned channel, began digital terrestrial television broadcast tests as early as 1999. Canal 13 followed in 2007, conducting tests specifically in Santiago using three different formats: ATSC, DVB, and ISDB.
Further regional efforts occurred in Valparaíso, where UCV TV planned to launch demonstrative ISDB-Tb broadcasting for the Valparaíso/Viña del Mar area in June 2010, utilizing an 800-watt transmitter.
High-Definition Content and Availability
While the terrestrial transition progressed, HDTV-ready television sets became widely available for purchase across the country. High-definition content has also been delivered via cable and satellite providers.
VTR, the largest cable TV provider in Chile, offers a limited selection of HD content to its subscribers. This includes 27 HD channels, consisting of 2 national-free channels, 4 premium channels, and 21 basic channels.
