The northwestern Mexican border city of Tijuana has become the first city in Latin America to convert to digital television broadcasts.
Some glitches were experienced after broadcasters switched off analog signals on Tuesday, officials said.
Federal officials will be asked to delay full implementation to avoid affecting residents who are still waiting for equipment to receive digital broadcasts, Tijuana Mayor Carlos Bustamante said.
Digital converter boxes and antennas were distributed to more than 192,000 low-income households in recent months to launch the program.
Mexico’s Teletec installed the digital equipment being used in Tijuana, which is located near San Diego, California.
The digital television launches in Matamoros, a border city in the northeastern state of Tamaulipas, and Monterrey, the capital of the northern state of Nuevo Leon, are scheduled for November.
Mexico City, Guadalajara and Mexico’s central region are slated to switch to digital television in November 2014, while the rest of the country will make the change in December 2015.
