What disc type system does this product support. DVD and Blu-Ray are common standards.

Dolby TrueHD: Dolby® TrueHD is the only audio format that delivers true high-definition sound, providing up to 7.1 channels of pristine, lossless audio 100 percent of the time. Dolby TrueHD will be found on HD DVD and Blu-ray Disc players and software, as well as in future A/V receivers and downloadable media.Dolby Digital: Dolby Digital brings the cinema experience home, delivering up to 5.1 channels of surround sound audio. Dolby Digital is the multichannel audio standard for DVD-Video, HDTV, digital cable, and direct broadcast satellite (DBS) systems.Dolby Digital Plus Dolby Digital Plus is the next-generation audio format that delivers "better-than-DVD" sound in high-definition packaged media because it requires less compression and provides more channels (up to 7.1). Dolby Digital Plus also provides new coding efficiencies for future broadcasting and streaming of multichannel audio.Dolby Digital EX: Dolby Digital EX creates a more intense surround sound experience by adding a sixth channel (Center Back) for enhanced localization of surround effects. It's optimized for Dolby Digital Surround EX™ content.Dolby Pro Logic: Dolby Pro Logic decodes Dolby Surround movie content into four playback channels of surround sound: Left, Center, Right, and Surround.Dolby Pro Logic II Dolby Pro Logic II transforms any stereo signal into five-channel, full-range surround sound. It’s found in the Apple® iPod®, in MP3 and CD playback, in VHS movies, in laser discs, and in stereo broadcasts.Dolby Pro Logic IIx Dolby Pro Logic IIx transforms any stereo or 5.1-channel signal into six- or seven-channel, full-range surround sound. This technology is featured in iPods, MP3 and CD playback, DVD-Video, VHS movies, laser discs, and stereo and surround broadcasts.

Progressive scan (also known as known as 480p, 525p, 575p, 720p) is one of two methods used for "painting" an image on a television screen (the other being interlaced scan), where the lines are drawn in one at a time in sequential order. The entire single frame image is painted every 1/60th of a second, allowing for twice the detail to be sent in the same amount of time used in interlaced systems. Progressive scan is a method used in today's CRTs, computer monitors and high-end television displays. Progressive scanning results in a more detailed image on the screen and is also less susceptible to the flicker commonly associated with interlaced scanning.Most television displays that are capable of progressive scanning can also perform deinterlacing, which enables interlaced video to be viewed on progressive scan sets. Progressive scan is now the standard of choice for both DVD video and DTV. To use and view progressive scanning technology the source (DVD player, High-definition cable or satellite for example) and the display must both be progressive scan compatible.

AM: AM radio is radio broadcasting using amplitude modulation. This was the dominant system of radio in the first two thirds of the 20th century, and it remains important into the 21st.Because of the inferior sound quality of AM broadcasting, the medium lends itself particularly to talk radio, while music radio has in recent decades tended to be broadcast using FM.AM radio technology is simpler than other types of radio, such as FM radio and DAB. An AM receiver detects the power of the radio wave and amplifies changes in the power measurement to drive a speaker or earphones. The earliest crystal radio receivers used this principle. FM: FM radio is a broadcast technology invented by Edwin Howard Armstrong that uses frequency modulation to provide high-fidelity broadcast radio sound.DAB Digital Audio Broadcast or DAB is a standard for digital radio broadcast developed by EUREKA as a research project for the European Union. (Project number EU147.) The technology was mainly developed in the 1980s, although the project started in the year 1987 and ended in 2000. Over 285 million people around the world can receive more than 550 different DAB services. The United Kingdom was the first country to receive a wide range of radio stations via DAB, with over 50 commercial and BBC services available in London in 2001.The DAB Forum represents more than 30 countries. The United States is not among them and uses IBOC to deliver digital radio.DAB uses the Eureka 147 protocol based on orthogonal frequency division modulation for transmitting digital data over a lossy radio channel.DAB broadcasts use the MP2 audio coding technique, a close relative of the popular MP3 format, which was also created as part of the EU147 project.DAB has the advantage that stations do not have be re-tuned as you move from area to area, such as in a car. Also, you can receive "radiotext" (in DAB terminology, Dynamic Label Segment, or DLS) from the station giving information such as song titles or traffic updates.Problems with the name Digital occurred with radios, as "digital" can be associated with a digital method of tuning, which is commonly found on analogue radios with LCD displays, rather than a digital signal. RDS: Radio Data System, or RDS, is a standard for sending small amounts of digital information using conventional FM radio broadcasts. The RDS system standardizes several types of information transmitted, including time and station identification. RDS is widely used in Europe, but less so in North America.Radio Broadcast Data System is the official name used for the U.S. version of RDS, though the "RDS" name seems to be at least as common in usage. The two standards are nearly identical, with only slight differences, mainly in which numbers are assigned to each of 31 musical and other program formats the RBDS system can identify. RBDS was approved by the NRSC, RDS by the EBU.

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.

(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.
