Appendix C Optimizing y our Netw or k Introduction In order for rich media to be an effective tool for your business you must first provision your network to support streaming. Below are some rules of thumb to ensure that video streaming will enhance your company’s performance without hurting your network performance.
Appendix C • Optimizing your Network not adversely affect other segments. In this case, clusters of people will have access to resources from the same common device that connects them to the backbone. Exploit new Technologies for your Backbone Your backbone should be larger than the pipes that connect to it.
Appendix C • Optimizing your Network Network Configurations that are friendly to Streaming 100BaseT Switched Networks More bandwidth is always better than less bandwidth. 100BaseT appliances have more features and more capabilities than 10BaseT appliances.
Appendix C • Optimizing your Network 124 (Metropolitan Area Network). LAN Emulation (LANE) is used in these types of networks to give an Ethernet feel to the network. This emulation is easier to implement than IP emulation over ATM and is much more popular.
Appendix D Glossar y of T er ms Access time – The time between issuing a command to read or write a specific location until reading or writing actually starts at that location (in mass storage devices). Algorithm – A detailed description of a method.
Appendix D • Glossary of Terms The letterbox method produces a black band at the top and bottom of the screen, wasting the television's vertical resolution. AVI – Refers to Audio Video Interleaved, the original term for Microsoft’s Video For Windows.
Appendix D • Glossary of Terms applications, buffers store vide o or audio data until there is enough information for the stream to be com posed. Bus Topology – A LAN network in which all nodes connect to the same cable. Data transmit across this one cable.
Appendix D • Glossary of Terms Color Noise – Random interference in the color portion of a composite video system. Because of reduced color bandwidth or color subsampling, color noise appears as relatively long streaks of incorrect color in the image.
Appendix D • Glossary of Terms outside the subnet and serves as connection between the current subnet and the outside world. DHCP – Refers to the Dynamic Host Configuration Protocol used by a host to obtain all necessary configuration information including IP addresses.
Appendix D • Glossary of Terms Driver – A software entity that provides a software interface to a specific piece of hardware. For example, the MPEG-5000 video driver provides software access to the video board hardware.
Appendix D • Glossary of Terms Frame – Refers to a single picture being part of a series. When the series is viewed at speed, a “moving picture” is created. Frame rate – The frame rate of a video sequence refers to how many frames are viewed per second.
Appendix D • Glossary of Terms I Frames – Intra Frames, which are key reference frames in the MPEG compression algorithm. I-frames contain all the data needed to represent an entire frame, IGMP .
Appendix D • Glossary of Terms KBps – Kilobytes per second. A date flow rate indicating exactly 2 10 bytes per second. Kiosk – A stand-alone unit being used for delivering information. Laser Disc – An analog storage device that can read video and sound.
Appendix D • Glossary of Terms Motion Compensation – A video compression technique that makes use of the redundancy between adjacent frames of motion video.
Appendix D • Glossary of Terms displayed at a rate of 25 frames per second. PAL is based on a 625/50-line/field system. The bandwidth for PAL is 5.5 MHz for luminance and 1.
Appendix D • Glossary of Terms SCSI (Small Computer System Interf ace) – Interface that allows up to 7 or 15 devices to be connected to a single SCSI port in series (daisy-chain). SDI – Refers to Serial Digital Interface, the standard based on a 270 Mbps transfer rate.
Appendix D • Glossary of Terms pixels and a refresh rate of 30 frames per second. Note that MPEG-1 allows resolutions up to 4095 x 4095 active pixels; however, there is a "constrained subset" of parameters defined as SIF.
Appendix D • Glossary of Terms remote timesharing system at another site as if the user’s keyboard and display connected directly to the remote machine. Threshold – In a digital circuit, a dividing line between circuit- signal levels representing different digital values.
Appendix D • Glossary of Terms a checkbox for AUTO SET UDP BLOCK SIZE. Leave this box checked unless there are many buffer overrun errors on the transmitter. If this is the case, deselect this option and increase the number displayed by about 10%. MPEG ComMotion PRO does not provide any AUTO SET for the UDP Block size.
Appendix D • Glossary of Terms 140 the association of host names and locations with IP addresses without an administrator having to be involved in each configuration change.
