Blu-ray and HD-DVD are the next generation of disc types allowing for high definition movies in 1080p. HD-DVD and Blu-Ray are not compatible with each other, but both types support normal DVDs.

Is the player a stationary player for home use without a screen, or is it a portable with a screen operated by batteries.

Indicates the types of discs the recorder can record on. Most recorders record on DVD but products with Blu-Ray and HD-DVD recording are on the horizon. Some products record both on discs and on an internal hard drive.

BD Live offer a variety of Web-enabled features, from downloadable trailers to chat and instant-messaging functions.

Upscaling is a process that mathematically matches the pixel count of the output of the DVD signal to the physical pixel count on an HDTV, which is typically 1280x720 (720p) or 1920x1080 (1080i).

Indicates that the DVD player is capable of processing and outputting progressive scan images via the progressive scan component video output. Progressive scan images look more film-like and is less subject to certain motion artifacts as common with "conventional" interlaced scanning. This type of video signal is useful only if you have a digital TV(or HDTV). If you don't have a progressive scan capable TV, you can still use interlaced video output to drive your current TV. To fully reduce motion artifacts, its recommended to use a progressive scan DVD player that performs 3:2 pulldown.

Indicates the physical disc formats supported by the player. This does not include any file formats which might be supported.

A SCART connector is a physical and electrical interconnection between two pieces of audio-visual equipment, such as a television set and a video cassette recorder (VCR). Each device has a female 21-pin connector interface. A cable with a male plug at each end is used to connect the devices. (The 21st pin is actually not a pin but a ground shield contact.) Stereo audio, composite video, and control signals are provided in both directions. RGB video signals are input only. The interface is an industry standard originated by the French company, Peritel. Today, most new television sets and VCRs in the European market and other countries that use the PAL video standard come equipped with a SCART connector. SCART stands for Syndicat francais des Constructeurs d'Appareils Radio et Television. The connector is also known as a Euro-connector.

HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface. By delivering crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable. HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new lossless digital audio formats Dolby TrueHD and DTS-HD with bandwidth to spare to accommodate future enhancements and requirements.

A digital coaxial connection refers to a wired connection that is used for transferring digital audio signals (such as PCM, Dolby Digital, and DTS) from a source device, such as CD or DVD player and an AV receiver or Surround Sound Preamp/Processor. Digital Coaxial Connections use RCA-style connection plugs.Also Known As: Digital Audio Connection, Digital Audio Coaxial Connection.

(Universal Serial Bus) A widely used hardware interface for attaching peripheral devices. USB ports began to appear on PCs in 1997, and Windows 98 was the first Windows to support it natively. Within a few years, USB became popular for connecting nearly every external peripheral device. Replacing the serial and parallel ports on a PC, at least four USB ports are standard on every computer.Hot SwappableUSB devices can be connected to without turning the computer off, enabling removable devices to be plugged and unplugged as needed. This feature, combined with easy-reach ports on the front of the computer case, gave rise to the ubiquitous USB drive.USB 1.0 and USB 2.0USB has a maximum bandwidth of 12 Mbps for USB 1.0 and 1.1 and 480 Mbps for Hi-Speed USB 2.0. Up to 127 peripheral devices can be attached to the bus, and USB 1.1 devices can plug into USB 2.0 ports. Fast devices can use the full bandwidth, while low-speed ones can use a 1.5 Mbps sub channel.USB HubsA USB hub provides additional ports for the user. Like any other USB device, the hub plugs into a USB port on the computer and provides four or more USB ports for peripherals. The peripherals themselves may also contain hubs. For example, a monitor may have a built-in USB hub in order to provide a convenient desktop location for plugging in other devices.Type A and B, Mini-A and BThe USB ports on computers and hubs have a rectangular Type A socket, and peripheral devices have a cable with a Type A plug. Peripherals that do not have an attached cable have a square Type B socket on the device and a separate cable with a Type A and Type B plug.The Mini-A and Mini-B connectors are used on small portable devices such as PDAs, music players, digital cameras and cell phones. Hubs may use Mini-B instead of Type B for the computer connection.
