Grupo Televisa said it has selected Envivio's standard definition encoders and decoders for the company's digital satellite news gathering (DSNG) operations. By deploying the MPEG-4 compression and decompression systems in news vans, and fixed and flyaway configurations, Televisa said it is looking to enhance image quality while requiring less than one half of the previous bit rate used for each transmission stream.
Televisa recently used the Envivio encoders to broadcast the 2006 presidential election in Mexico and the FIFA World Cup in Germany, the company said.
Televisa is the largest media company in the Spanish-speaking world with three national television networks - Channels 2, 5 and 9 - that are comprised of 225 stations nationwide, and reach 99 percent of Mexico's television households with 74 percent of the television audience share.
Maintaining picture quality while lowering bit rates were key goals for Televisa when selecting MPEG-4 systems for news contribution feeds. With the Envivio systems, Televisa is now encoding at 2 Mbps, providing considerable bandwidth savings over its previous MPEG-2 solution which was operating at 5 Mbps. At present, Televisa has deployed 40 of the Envivio Broadcast Series standard definition 4Caster B3 encoders and 10 4View D1 professional decoders.
