1 | |acceleratorkey| | |accelerator keys| | |<P>A key or combination of keys that when pressed will quickly perform an action within an application that would normally require several user actions | such as menu selections.| |
2 | |analog| | |analog| | |<P>The traditional format in which audio and video are transmitted using a wave or analog signal. | |
3 | |anchorwindow| | |anchor window| | |<P>A small window that is displayed in the lower-right corner of the screen when Windows Media Player is in compact mode. See also compact mode.| |
4 | |band| | |band| | |<P>The transmission method used by the radio station (AM | FM | or Internet). Internet radio stations usually play a preset | taped list of songs and commercials. | |
5 | |Bandwidth| | |bandwidth| | |<P>The data transfer capacity of a digital communications system | such as the Internet or a local area network (LAN). Bandwidth is usually expressed in the number of bits that a system is capable of transferring in a second: bits per second (bps). High bandwidth or broadband refers to a network capable of a fast data transfer rate.| |
6 | |Bitrate| | |bit rate| | |<P>The speed at which digital audio and video content streams from a source | such as a file | to be rendered properly by a player | or the speed at which binary content in general is streamed on a network. Bit rate is usually measured in kilobits per second (Kbps) | for example | 28.8 Kbps. The bit rate of a Windows Media file or live stream is determined during the encoding process | when the streaming content is created. Bandwidth is the total bit-rate capacity of a network. For audio and video content to render properly when streaming over a network | the bandwidth of the network must be high enough to accommodate the bit rates of all the different content that is being streamed concurrently.| |
7 | |broadband| | |broadband| | |<P>A high-speed transmission. The term is commonly used to refer to communications lines or services at T1 rates (1.544 Mbps) or cable modem rates and above.| |
8 | |Bufferandbuffering| | |buffer| | |<P>A small amount of RAM that Windows Media Player uses as a loading area for information before playing it. When you play a file or stream | Windows Media Player fills up the buffer before it begins playing so that you won't notice minor problems with traffic on the Internet or the local network. | |
9 | |callsign| | |call sign| | |<P>The identifying code letters or numbers of a radio or television transmitting station | assigned by a regulatory body.| |
10 | |captions| | |captions| | |<P>Text that describes the audio or video you are playing | similar to closed-captioning.| |

13 | |codec| | |codec| | |<P>Short for compressor/decompressor. Codecs are various types of computer algorithms that are applied to audio | video | and image files to compress the size of the files. The benefit of this is the files do not use as much disk space when stored or as much network bandwidth when streamed. To open a compressed file | the same codec must be used to decompress the file. If your computer does not have the correct codec to decompress a file | Windows Media Player will attempt to download the codec for you. | |

You can customize this Windows Media Player mode by applying a different skin. To make sure you are in compact mode | press CTRL+2. | |
16 | |compression| | |compression| | |<P>The coding of data to reduce file size or the bit rate of a stream. Content that has been compressed is decompressed for playback.| |
17 | |compressionquality| | |compression quality| | |<P>Determines the quality of the digital audio as the data is copied to your computer or portable device | or the quality of music as it is streamed to Windows Media Player. The better the compression quality used | the more disk space a copied file uses.| |
18 | |connectionspeed| | |connection speed| | |<P>The speed at which your computer connects to the Internet or a network.| |
19 | |digitalcopying| | |digital copying| | |<P>A method of copying media items using a digital format.| |
20 | |digitalplayback| | |digital playback| | |<P>The process of playing a media item using a digital format. Computers use digital format | so data must be converted to this format | and then encoded to be played on a computer. Data that is digital has been converted to ones and zeros.| |
21 | |download| | |download| | |<P>A method of delivering content over a network in which the content is copied to a client computer and then played locally. This method is different from streaming because the source media is copied from the server to the client computer. See also streaming | |
22 | |encode| | |encode| | |<P>The process of compressing and separating a file into packets of information for delivery over a network. Windows Media Player can play a file that has been encoded into a Windows Media file (the file created when you copy a CD track) or stream (what your computer receives when you listen to a live radio station delivered over the Internet).| |
23 | |encrypt| | |encrypt| | |<P>The process of packaging media items with a key. Once a media item has been encrypted | it cannot be played without the key. | |

35 | |Licensedfiles| | |licensed files| | |<P>Windows Media files that have an associated license restricting the copying of that file. The restrictions stated in the license will vary depending on the license creator.

37 | |mediainformation| | |media information| | |<P>Information | such as the album cover | label | artist name | and length | gathered from the Internet about a CD. An Internet connection is required to access this information.| |
38 | |MovingPictureExpertsGroup| | |Moving Picture Experts Group (MPEG)| | |<P>A set of standards for audio and video compression established by the Joint ISO/IEC Technical Committee on Information Technology. The MPEG standard has different types that have been designed to work in different situations.| |
39 | |MP30| | |MP3 (MPEG Audio Layer 3)| | |<P>A computer file format that compresses audio files far smaller than previously required for CD-quality recordings. A minute of music | or several minutes of spoken words | encoded in MP3 require only about one megabyte of disc space | about one-tenth of what the older .wav format required. MP3 has made quick transfer of CD-quality music over the Internet practical. | |
40 | |multicast| | |multicast| | |<P>A one-to-many client/server connection in which multiple clients receive the same stream from a server. To receive a multicast | a client listens to a specific IP address on a multicast-enabled network | like tuning a television to a specific channel. In contrast | a unicast is a one-to-one connection in which each client receives a separate stream from a server.| |
41 | |Multiplebitrates| | |multiple bit rates| | |<P>A term used to identify streams that can be delivered at several speeds. Typically a stream has only one speed or bit rate. However | some streams are created so that if network traffic hinders the delivery of the stream | the stream will switch to a lower bit rate in an attempt to make the flow of information consistent. If the flow of information slows down | youÆll notice breaks in the audio and/or video or the stream will stop.| |
42 | |MusicalinstrumentdigitalinterfaceMIDI| | |musical instrument digital interface (MIDI)| | |<P>An agreed-upon structure for representing musical sounds | such as from a synthesizer | in a form that a computer can interpret. | |

Streaming data enables Windows Media Player to begin rendering the data immediately instead of waiting for the entire file to be downloaded.| |
52 | |tracks| | |tracks| | |<P>The individual songs from a CD.| |
53 | |TCP| | |Transmission Control Protocol (TCP)| | |<P>The protocol within TCP/IP that governs the breakup of data messages into packets to be sent via IP | and the reassembly and verification of the complete messages from packets received by IP.| |
54 | |UDP| | |User Datagram Protocol (UDP)| | |<P>The connectionless protocol within TCP/IP that corresponds to the transport layer in the ISO/OSI model. UDP converts data messages generated by an application into packets to be sent via IP but does not verify that messages have been delivered correctly.| |
