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 Composite Video Connection is a connection in which both the Color and B/W portions of the video signal are transferred together. The actual physical connection is referred to as an RCA video connection and is usually Yellow at the tips.Also Known As: RCA video connection, Composite Video, Standard Video Connection

Short for Super-Video, a technology for transmitting video signals over a cable by dividing the video information into two separate signals: one for color (chrominance), and the other for brightness (luminance). When sent to a television, this produces sharper images than composite video, where the video information is transmitted as a single signal over one wire. This is because televisions are designed to display separate Luminance (Y) and Chrominance (C) signals. (The terms Y/C video and S-Video are the same.)To use S-Video, the device sending the signals must support S-Video output and the device receiving the signals must have an S-Video input jack.

The three-jack (RCA/Phono) component video connection splits the video signal into three parts (one brightness and two color signals). Component video has increased bandwidth for color information, resulting in a more accurate picture with clearer color reproduction and less bleeding. A growing number of TVs include component video jacks to provide the best possible picture quality (better than S-video or composite video) when connected to a compatible DVD player. Special wide-bandwidth component video connections are capable of carrying wider bandwidth video signals, like progressive-scan DVD and High-Definition digital television. All HDTV-ready TVs include at least one set of wide-bandwidth connections for connecting a separate HDTV tuner (or progressive-scan DVD player). A component video connection can carry high bandwidth signals such as 1080i and 720p.

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.

Ethernet is a network standard of communication using either coaxial or twisted pair cable. The most widely used for of LAN communication, Ethernet typically runs at 10 megabytes per second, though newer systems use 100 Mbps and even 1 gigabit of transfer.Ethernet has the IEEE standard 802.3. It has several different flavors, with the original Ethernet designed with 10base5. The "10" stands for 10 megabytes per second. Base is the baseband communications it uses. The "5" stands for a maximum distance of 500 meters to communicate with. Original Ethernet used coaxial wiring, while newer versions use twisted-pair cabling. There are several flavors of Ethernet, including 10Base2 (10 Mbps, 200 meters), 10BaseT (10 Mbps, 100 meters, twisted-pair), and 100BaseT (100 Mbps, 100 meter, twisted-pair).
