HDD
Hard Disk Drive is a storage device found in computers and PVR devices. Data is recorded on magnetic disks that spin at around 7200rpm. They are now capable of storing Terabytes of data.
HDMI
HDMI stands for High-Definition Multimedia Interface and offers an easy and convenient way of interconnecting digital audio-video components. With HDMI, digital signals are not compressed – transmission is direct. Because the signal stays in the digital format, it is free from the degradation and noise that occurs with analogue signal transmission.
HDTV
HDTV stands for High-Definition Television. This highest-resolution subset of Digital Television offers film-like picture quality with impressive surround sound. HDTV has a widescreen aspect ratio of 16:9 and Dolby Digital sound.
HD ready
HD ready is a labelling scheme introduced by the TV manufacturers’ organisation, the European Industry Association for Information Systems (EICTA). The label means the TV has the minimum screen resolution (at least 1280×720) and digital sockets (HDMI or DVI) to receive and display an HD picture.
HEPA (High Efficiency Particulate Air)
This filter removes most allergens, irritants and pollutants like pollen, spores, dust mites and bacteria. It offers perfect protection for allergy and asthma sufferers.
HighMAT
Panasonic DVD players equipped with HighMAT (High-performance Media Access Technology – a joint development with Microsoft) can handle discs with a mixture of data (such as different types of picture and sound files) more quickly, smoothly and easily. HighMAT benefits include quicker disc start-up, rapid data access, and easier track navigation thanks to playlist menus.
Hub
A device for connecting multiple Ethernet devices together to join a single network. Fairly unsophisticated as they do not manage network traffic, unlike a network switch.
