5 terms

digital terrestrial television (dtt) technical

"across its digital terrestrial television (DTT) network."

Digital terrestrial television (DTT) is the delivery of TV channels over the air from ground-based broadcast towers to homes using digital signals rather than old analog signals, enabling more channels, clearer pictures and extra features over the same broadcast space. Investors care because DTT affects how audiences are reached and monetized—driving demand for broadcast licenses, advertising, set-top boxes and smart TVs—and often triggers one-time upgrade spending plus ongoing changes in viewership and revenue models.

multiplex bandwidth technical

"within the same multiplex bandwidth that previously carried five HD channels."

Multiplex bandwidth is the total data-carrying capacity of a communication link that combines multiple separate data streams into one transmission. Like a multi-lane highway carrying many cars at once, higher multiplex bandwidth lets a network, service provider, or device deliver more video, voice, or sensor data simultaneously, which influences customer experience, potential revenue, capital investment needs, and competitive position.

hevc technical

"The XOS processor supports HEVC encoding and 1080p source processing"

High Efficiency Video Coding (HEVC), also known as H.265, is a video compression standard that squeezes high-quality video into smaller files so it uses less bandwidth and storage. For investors, HEVC matters because its adoption influences costs and performance for streaming services, device makers, and content distributors—similar to fitting more clothes into the same suitcase, it can reduce delivery expenses and enable higher-resolution video on existing networks.

hdr dolby vision technical

"1080p source processing with HDR Dolby Vision, providing TDF with a future-ready solution"

HDR Dolby Vision is a premium video format that expands the range of brightness and color on screens, making highlights brighter and shadows more detailed—think of it as upgrading from a basic photo to one with richer contrast and truer colors. For investors, its presence signals higher-end hardware, licensing revenue, and demand for compatible content and devices, which can affect sales, margins, and partnerships across media, chipmakers, and consumer electronics.

remote statistical multiplexing technical

"ProStream X stream processor provides remote statistical multiplexing, allowing bandwidth sharing"

Remote statistical multiplexing is a way service providers combine many customers’ data streams onto shared network capacity using software and real‑time traffic patterns, often managed from a central or cloud location. Like a ride‑share that fills cars based on who needs a trip when, it lets firms use less dedicated hardware while handling bursts of demand, affecting service quality, cost structure and how efficiently a company can scale its network services — key factors for investors assessing margins and growth.
