C—H

channel: A defined location from which a NetShow Player can receive streams. A NetShow channel is analogous to a television channel or a radio frequency: it is defined and, if the client Player is tuned there at appropriate time, it delivers streams to the client. The channel also specifies the types and formats of the data in the stream so that the client can play the stream correctly. Channel information is saved as a file with an .nsc extension. NetShow uses channels with ASF streams only.
codec: (Compressor/Decompressor) An algorithm or scheme used when recording digital video or audio. A codec comes into play, for example, when video is transmitted over the Internet; the video must be compressed on the sending end and decompressed on the receiving end. NetShow provides numerous codecs for NetShow content. Choose a codec based on the audio or image quality and image size that you prefer.
events (Language): An action recognized by an object, such as an ActiveX control, and for which you can write code to respond. Events can occur as a result of a user action or program code, or they can by triggered by the operating system.
events (System): System occurrences, such as user logons, that are logged to a tool designed to monitor such occurrences and to display them in a window or log them to a file. NetShow Server Trace, which is included with the NetShow Administrator, logs NetShow events to a window. NetShow Server Log saves these events in a database. There are also events sent by NetShow services to the Windows NT event log, where they can be viewed with the Windows NT Event Viewer.
File Transfer service (FTS): A component of NetShow that sends files over a network using a multicasting transfer mechanism. A NetShow FTS server transmits files across a network to an ActiveX control on a client computer.
firewall: A system or combination of systems that enforces a boundary between two or more networks and keeps unauthorized users out of private networks.
Hypertext Markup Language (HTML): The language used to format information displayed on corporate intranets and the World Wide Web. HTML is a subset of Standard Generalized Markup Language (SGML), and like SGML, HTML uses tags to identify the format for a particular piece of information.
Hypertext Transfer Protocol (HTTP): A protocol used to access information over intranets and the Internet. Other common protocols are FTP and Gopher.
