Harmonic Introduces New HD Multi-Codec Encoder

Harmonic introduced its new DiviCom MV 3500 encoding platform, a multi-format high definition (HD) encoder supporting either MPEG-4 AVC (H.264), SMPTE VC-1 or MPEG-2. The full-featured DiviCom 3500 encoding platform, which builds on Harmonic's existing lines of multi-codec standard definition encoders, provides the performance, video quality and interoperability -- from the headend to the subscriber premises -- that operators need to offer a rich HD experience at low bit-rates.

The MV 3500 supports constant bit-rate (CBR) and variable bit-rate (VBR) encoding, and can deliver digital content in a variety of formats -- including 1080i and 720p -- and resolutions. It incorporates compression technology pioneered by Harmonic -- such as "MotionTrack" which provides full-field motion estimation, multi-pass "LookAhead" analysis and advanced video filtering -- to yield superior quality HD video at the lowest possible bit-rate. The MV 3500 is also the industry's first HD encoder to feature advanced pre-processing functions such as Motion Compensated Temporal Filtering (MCTF), which removes noise without introducing motion blur artifacts.

To ensure viewers receive the full HD experience, Harmonic's new HD platform supports multiple audio encoding formats such as MPEG Layer II, AC-3, AAC, aacPlus, and AC-3 5.1 pass-through. The system's flexible software architecture and substantial processing power make it possible for operators to benefit from new compression and video quality enhancements, features and codecs, delivering better value for the operator over the long-term.

Harmonic said that by using the MV 3500 in CBR mode, DSL operators will be able to viably introduce competitive HDTV, voice and data services. Satellite distribution and direct-to-home service providers deploying the VBR version of the new encoder can greatly increase the HD channel carrying capacity of their existing transports.
