KTVA Becomes First HD Television Station in Alaska with Video Processing & Server Solutions from Harmonic

Recently, KTVA Alaska, a CBS-affiliate station owned by Denali Media Holdings, built a brand new media center in Anchorage as part of a massive upgrade to enable high-definition broadcast. KTVA wanted a media center with optimized workflows that support maximum flexibility and productivity in managing, sharing, creating and delivering quality content. Ensuring superior video quality was equally important. Since the station was transitioning from SD to HD, it needed a video processing solution that guarantees crystal-clear quality for viewers.

For the project, KTVA chose to deploy a broad array of solutions from Harmonic. The upgrade was engineered, integrated and installed by TI Broadcast Solutions Group (TIBSG), based in Norcross, Ga. The facility is using Harmonic’s Electra 9200 universal multiservice encoders, ProMedia Carbon file-based transcoders, Spectrum ChannelPort integrated channel playout system and Spectrum MediaDeck integrated media servers to enable flexible, efficient centralcasting for three new TV stations, including KTVA.

Harmonic’s Electra 9200 multichannel, multiservice encoder enables KTVA to efficiently encode and stat mux both SD and HD MPEG-2 services, while offering a clear-cut upgrade path to MPEG-4 AVC. The Electra encoder features a compact, energy-efficient 1U chassis that minimizes the station’s capital and operating expenses while ensuring a superior on-air presentation for viewers.

Harmonic’s ProMedia Carbon file-based transcoding solution complements the Electra encoder by facilitating the conversion of media to a massive array of acquisition, editing, broadcast, web and mobile formats. Using ProMedia Carbon, the station can transcode content in virtually any media format to every media standard in use today. The application is continually updated to accommodate new formats, ensuring KTVA is able to meet ever-evolving content production and distribution requirements.

The ChannelPort system provides KTVA with powerful channel-in-a-box capabilities, enabling the keying of multilayer graphics and dynamic text over playback or live video to produce rich on-air looks. Because ChannelPort modules fit seamlessly into new or existing Spectrum media server systems and can be added incrementally, KTVA can easily extend its channel lineup in the future.

Together, these Harmonic solutions allow KTVA to realize high performance in processing media for virtually any outlet or platform. Since deploying flexible, scalable and efficient video infrastructure solutions from Harmonic, the station can cost-effectively deliver SD and HD channels to viewers with an astounding video quality.
