Amarillo, Texas-based PBS member station KACV has chosen Leitch's AgileVision system to upgrade its digital broadcasting infrastructure.
KACV is the ninth PBS station to choose AgileVision for its digital transition. "Leitch's AgileVision was a good choice for us because the system handles EAS better than any other product," said Dan Ford, director of engineering for KACV. Furthermore the AgileVision system eliminates the need to decode and then re-encode the PBS network's compressed satellite system, and all manipulation is performed in a single unit."
The AgileVision system uses an MPEG-2-based method for implementing EAS (Emergency Alert System) into a DTV broadcast. EAS decoders can interface with the AgileVision, and the EAS text and audio are overlaid on all on-air DTV channels. At this time, the number and type of channels that are on air at are abstracted and the system routes the EAS text and audio to the proper channels.
In the compressed domain, features of the AgileVision include HD and SD splicing, logo overlays and rate control. It has integrated MPEG-2 real-time encoders, high-capacity storage, PSIP generation, datacasting services multiplexing and automation/control features.
