7 terms

uhd technical

"Offering up to eight HD channels or two UHD channels per server"

Ultra High Definition (UHD) describes a video or display resolution that has roughly four times the pixels of standard high definition, producing noticeably sharper, more detailed images—think of moving from a newspaper photo to a fine-print magazine image. Investors care because UHD drives demand for higher-end TVs, monitors, streaming services and content production, which can shift sales, pricing power and manufacturing costs across consumer electronics and media companies.

hdr technical

"support for UHD workflows such as 3D LUT-based HDR conversions"

High-dose-rate (HDR) refers to a form of localized radiation therapy that delivers a strong, concentrated beam of radiation to a targeted spot for a short time, often using a temporary implant placed close to a tumor. Investors care because HDR treatments can offer faster procedures, shorter hospital stays and potentially better targeting than traditional options, which can affect adoption of related devices, treatment volumes, reimbursement and therefore a healthcare company's revenue prospects.

dolby atmos technical

"immersive audio formats such as Dolby Atmos and MPEG-H"

Dolby Atmos is a branded audio technology that creates three-dimensional, moving sound by placing audio “objects” around and above the listener instead of just left/right channels. For investors it matters because widespread use of this technology can raise the value of devices, streaming content and venues that support it, drive licensing and hardware sales, and become a competitive feature that helps companies charge higher prices or attract more users—like upgrading from a flat painting to a surround sculpture for sound.

mpeg-h technical

"immersive audio formats such as Dolby Atmos and MPEG-H"

MPEG‑H is a family of international standards for next‑generation audio and video coding used in broadcasting and streaming; it covers efficient video compression (including what is commonly called HEVC) and an advanced, object‑based audio system that lets sound be mixed and personalized for listeners. Investors care because adoption of these standards affects demand for chips, software licenses, content delivery and consumer devices—similar to how a new highway design changes which transport companies and vehicle makers prosper.

smpte st 2110 technical

"enhances performance for SMPTE ST 2110 environments, supporting SDI and SMPTE ST 2110 IP I/O"

SMPTE ST 2110 is an industry standard that defines how live video, audio and related data are sent over regular IP networks instead of traditional broadcast cables, keeping each type of media separate so systems can mix and match components. Think of it as replacing many proprietary roads with a common highway system that lets broadcasters use off‑the‑shelf networking gear, increase flexibility and scale more cheaply. For investors, adoption affects spending on upgrades, vendor competition, and the speed at which new services and efficiencies can be rolled out.

gpu acceleration technical

"software-driven architecture also enables GPU acceleration and deployment of AI-based capabilities"

GPU acceleration means using graphics processors—chips designed to run many small tasks at the same time—to speed up heavy computations like machine learning, data analysis, or video rendering. Investors care because faster processing can lower costs, enable new products or services, and give companies a competitive edge much like hiring a team of specialists instead of one person doing every job slowly.

channel-in-a-box technical

"supports multi-channel ingest, studio and news production, channel-in-a-box and integrated playout workflows"

A channel-in-a-box is a single, compact hardware or software system that handles all the tasks needed to run a TV or streaming channel — playing programs and ads, inserting graphics, managing schedules and switching between feeds. For investors, it matters because it can sharply reduce setup and operating costs, speed up deployment and simplify upgrades compared with many separate devices, making broadcasters and streaming services more efficient and scalable, like replacing a full kitchen of appliances with one multi-function machine.

Advanced Media Server Delivers Double the Channel Density at Half the Cost per Channel of Previous Generations

SAN JOSE, Calif., March 12, 2026 /PRNewswire/ -- Harmonic (NASDAQ: HLIT) today announced Spectrum™ X Plus, the newest generation of its Spectrum X media server, offering double the channel density of previous generations. Spectrum X Plus dramatically simplifies video ingest and playout functions for broadcasters and content owners, significantly lowering the total cost per channel for broadcast delivery. Spectrum X Plus strengthens Harmonic's leadership in playout-to-delivery solutions by enabling broadcasters to deploy high performance playout infrastructure on premises, in the cloud with Harmonic's VOS^®360 Media SaaS, and in hybrid environments.

"As broadcasters face growing cost pressures and increasingly complex workflows, Spectrum X Plus provides the flexibility, performance and future-ready architecture they need to modernize ingest, production and playout operations." said Stephane Cloirec, vice president, video appliance and software product management at Harmonic. "With Spectrum X Plus, we're responding to customer demand for higher channel density and lower cost per channel without compromising the outstanding quality and reliability that Harmonic solutions are known for. The next-generation media server also paves the way for future integration of AI-based applications such as Harmonic's AI orchestration service."

Efficiency Gains with Lower Cost Per Channel
Offering up to eight HD channels or two UHD channels per server, Spectrum X Plus significantly reduces rack space, power consumption and operating costs for broadcasters and content owners.  The high-performance baseband video server supports multi-channel ingest, studio and news production, channel-in-a-box and integrated playout workflows.

Advanced Capabilities for Enhanced Video Playout
Spectrum X Plus streamlines video playout with integrated onboard graphics, audio loudness control, MCR switching and subtitle insertion. The media server also provides innovative capabilities for next-generation production including support for UHD workflows such as 3D LUT-based HDR conversions, immersive audio formats such as Dolby Atmos and MPEG-H as well as multiple resolutions, frame rates and codec formats.

Seamless Transition to IP
Built on a flexible, software-based architecture, Spectrum X Plus eliminates the constraints of traditional hardware-centric systems. The next-generation media server enhances performance for SMPTE ST 2110 environments, supporting SDI and SMPTE ST 2110 IP I/O, or hybrid configurations. This advanced feature enables broadcasters to transition seamlessly from traditional SDI to fully IP-based workflows.

Streamlined Expansion to Cloud Playout
Spectrum X Plus shares the same file and graphics formats with VOS360 Media and can be controlled by the same automation and traffic systems. This enables broadcasters to easily expand any Spectrum X system with cloud playout resources. The transition is seamless for broadcasters, allowing hybrid playout infrastructures to support service continuity and the rapid launch of pop-up channels in the cloud through fluid operations.

AI-Ready Architecture with GPU Acceleration
The media server's software-driven architecture also enables GPU acceleration and deployment of AI-based capabilities such as automated captioning, translation and other value-added workflows, helping broadcasters further streamline operations and reduce costs.

Harmonic will demonstrate its new Spectrum X Plus media server at the 2026 NAB Show, April 19-22, in Las Vegas in stand W2831.
