A web browser is a client program that requests services the sending of web pages or files from a web server CMOS Complementary Metal Oxide Semiconductor A CMOS is a widely used type of semiconductor that uses both negative and positive circuits Since only one of the circuit types is on at any given time CMOS chips require less power than chips using just one type of transistor CMOS image sensors also allow processing circuits to be included on the same chip an advantage not possible with CCD sensors which are also much more expensive to produce Coaxial cable Coaxial cable is the standard means of transmitting analog video in a CCTV system Coaxial is also used by cable companies to distribute television in residential buildings Codec In communications engineering a codec is usually a coder decoder Codecs are used in integrated circuits or chips that convert e g analog video and audio signals into a digital format for transmission The codec also converts received digital signals back into analog format A codec uses analog to digital conversion and digital to analog conversion in the same chip Codec can also mean compression decompression in which case it is generally taken to mean an algorithm or computer program for reducing the size of large files and programs Composite video A type of video signal in which the red blue and green signals sometimes audio signals too are mixed together Compression See

AXIS Media Control supports both object types while QuickTime for example requires the Simple object type When using MPEG 4 it is also possible to control the bit rate which in turn allows control of bandwidth usage CBR constant bit rate is used to achieve a specific bit rate by varying the quality of the MPEG 4 stream When using VBR variable bit rate the quality of the video stream is kept as constant as possible at the cost of a varying bit rate Notes e MPEG 4 is licensed technology AXIS 243SA includes one license for the decoder required for viewing in AMC Installing additional unlicensed copies of this decoder is prohibited To purchase more decoder licenses contact your Axis reseller e All clients viewing the MPEG 4 stream must use the same image settings Video and audio streams MPEG 4 protocols and communication methods To deliver live streaming video over IP networks various combinations of transport protocols and broadcast methods are employed RTP Real Time Transport Protocol is a protocol that allows programs to manage the real time transmission of multimedia data via unicast or multicast RTSP Real Time Streaming Protocol serves as a control protocol to negotiate which transport protocol to use for the stream RTSP is thus used by a viewing client to start a unicast session see below UDP User Datagram Protocol is a communications protocol that offers limited service for exchanging data in a netw

38. The Internet Protocol is a method transmitting data over a network Data to be sent is divided into individual and completely independent packets Each computer or host on the Internet has at least one address that uniquely identifies it from all others and each data packet contains both the sender s address and the receiver s address The Internet Protocol ensures that the data packets all arrive at the intended address As IP is a connectionless protocol which means that there is no established connection between the communication end points packets can be sent via different routes and do not need to arrive at the destination in the correct order Once the data packets have arrived at the correct destination another protocol Transmission Control Protocol TCP puts them in the right order See also TCP IP address An IP address is simply an address on an IP network used by a computer device connected to that network IP addresses allow all the connected computers devices to find each other and to pass data back and forth To avoid conflicts each IP address on any given network must be unique An IP address can be assigned as fixed so that it does not change or it can be assigned dynamically and automatically by DHCP An IP address consists of four groups or quads of decimal digits separated by periods e g 130 5 5 25 Different parts of the address represent different things Some part will represent the network
