VHSVHS (short term for Video Home System) is a standard for consumer-level analog video recording on tape cassettes invented in 1976 by the Victor Company of Japan and was the competitor to the ill-fated Sony Betamax system. Magnetic tape video recording was adopted by the television industry in the 1950s in the form of the first commercialized video tape recorders (VTRs), but the devices were expensive and used only in professional environments.
Power over EthernetPower over Ethernet, or PoE, describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power devices such as wireless access points (WAPs), Internet Protocol (IP) cameras and voice over Internet Protocol (VoIP) phones. There are several common techniques for transmitting power over Ethernet cabling.
H.323H.323 is a recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences. It is widely implemented by voice and videoconferencing equipment manufacturers, is used within various Internet real-time applications such as GnuGK and NetMeeting and is widely deployed worldwide by service providers and enterprises for both voice and video services over IP networks.
Work for hireA work made for hire (work for hire or WFH), in copyright law in the United States, is a work that is subject to copyright and is created by employees as part of their job or some limited types of works for which all parties agree in writing to the WFH designation. Work for hire is a statutorily defined term () and so a work for hire is not created merely because parties to an agreement state that the work is a work for hire. It is an exception to the general rule that the person who actually creates a work is the legally-recognized author of that work.
