Harmonic said its real-time stream processor, The ProStream 9100, now has the ability to perform linear ad splicing.

Service providers and broadcasters can use the system to insert targeted local and regional advertisements into broadcast programming delivered via MPEG-2 and MPEG-4 AVC SD/HD transport streams. The new linear ad splicing capability fully conforms to the SCTE 35 protocol.

The new splicing feature obviates the necessity for a separate ad splicing system, and also eliminates the need to decode a transport stream for insertion into regional advertising. 

In addition to linear ad splicing, Harmonic's ProStream 9100 supports 2 gigabytes of data throughput and up to 500 simultaneous multiplexing/scrambling services.

When paired with Harmonic's ACE transcoding technology, the ProStream 9100 can support 20 HD or 60 SD broadcast transcoding services, 20 HD/SD multiscreen inputs with 80 multiscreen output profiles, and integrated any-to-any audio transcoding with audio leveling capabilities in a single rack unit, the company said.

"Utilizing the high-density ProStream 9100 stream processor, local broadcasters and service providers now have the opportunity to boost their revenue streams by allowing advertisers to reach differentiated viewers with targeted ads," said Krishnan Padmanabhan, senior vice president, video products at Harmonic. "ProStream 9100 supports a variety of complex digital processing applications, including scrambling, multiplexing, transcoding, and now linear ad splicing, from a single rack unit, making it an incredibly versatile solution for advanced broadcast applications."
