Stream Processing

Stream Processing

Multiplexing, Splicing and Scrambling are basic functions of any television headend. They have been implemented by operators in the broadcast industry for many years. Harmonic's third generation of stream processing solutions features an unparalleled density and capacity to evolve.

Scrambling

Harmonic's ProStream™ 1000 stream processing platform is a versatile, dense (1RU), IP-based solution that offers unequalled capacity for delivering more than 100 video services to any network or device. Equipped with the ProCipher™ IP scrambling technology the ProStream 1000 is designed to multiplex and scramble any format of video, audio and data elementary streams (MPEG-2, MPEG-4 AVC/H.264, AC3, AAC, AACPlus).

This embedded platform supports DVB-CSA with or without smart card as well as AES. It is compatible with third party Conditional Access systems and provides a stable and reliable solution that integrates easily into existing or new Headend architectures. In addition, the ProStream 1000 reduces costs and complexity as it eliminates the need for multiple devices or software-based IP scrambling solutions in distributed telecom networks.

Splicing

Harmonic's ProStream 2000 is the industry’s first splicer featuring multi-channel and multi-service capabilities within a compact 1-RU chassis, and supporting multiple SD or HD streams. It features a multi-service HD and SD MPEG-4 AVC (H.264) digital splicer that supports real-time and seamless splicing of multiple compressed video and audio services, primarily for ad insertion applications. Based on open standards, the IP-based ProStream 2000 is fully integrated with Harmonic’s DiviCom Electra encoders, ProStream 1000 stream processing platform, DiviTrackIP distributed statistical multiplexer, NMX Digital Service Manager and ad servers from various leading suppliers.

The ProStream 2000 preserves the video quality, which is not always the case with other splicing solutions. In addition, with its density and versatility, the ProStream 2000 offers a lower cost per channel and allows to build a scalable and distributed architecture. As a result, IPTV operators can more effectively insert national or local ads into their digital stream and better take advantage of incremental revenue opportunities as they launch new HD H.264 services.
