    Port Number A port number is combined with the IP address to create an application-specific or process-specific address. The port number can uniquely identify an application or process on a computer and thereby enable the computer to share a single Ethernet connection for multiple requirements.

  • Page 103: Streaming Method Overview

    With Push streams, the stream from the SME 211 becomes active immediately on the network, but the receiver must accept the stream before it can be decoded and displayed. With Pull streams, the SME 211 waits for individual viewing devices to request the stream before beginning transmission on the network.
  • Page 104 Multicast streaming is used for live audio and video applications which require “one-to- many” delivery of content. The SME 211 allows the use of a variety of streaming protocols to send data to multicast groups. This allows many users to view the data simultaneously while using bandwidth efficiently.

  • Page 105: Streaming Playback Methods

    The client computer or media player, such as Extron SMD 101 or SMD 202 products, must be provided with connection details to the SME 211 for active (push) and available (pull) streams and streams must be enabled or requested by the media player to begin decoding and displaying the stream content.

    • Streaming Pull Streaming Method = Unicast RTP Unicast Push Stream Method The SME 211 supports one UDP/RTP push stream and one RTMP push stream per encoder. Available Multicast Streams The SME 211 uses the IGMP multicast protocol to push or pull streams. The IGMP multicast protocol provides increased bandwidth efficiency because network equipment is able to manage the traffic efficiently when correctly configured.

CBR is useful for streaming multimedia content on data communication channels which operate more efficiently or require the bit rate to remain within a tight tolerance.

Ethernet and LAN technology are used for interconnecting computers, printers, workstations, terminals, services, and similar devices, within the same building or campus. Ethernet operates over twisted pair and over coaxial cable at speeds starting at 10 Mbps. For LAN interconnectivity, Ethernet is a physical link and data link protocol reflecting the two lowest layers of the OSI Reference Model.
  • Page 120 Internet Group Management Protocol (IGMP) — A TCP/IP communications protocol used by hosts and adjacent routers on a network to establish multicast group memberships. The IGMP multicast protocol conserves network bandwidth because network equipment can efficiently deliver streams from the SME 211 when requested by the user or decoder. All network switches and routing equipment must be properly configured to support IGMP snooping, IGMP queries, and multicast filtering to avoid flooding all endpoints with unnecessary streaming traffic.
  • Page 121 Multicast — A network technology for the delivery of information to a group of destinations simultaneously. A single stream is sent from the source to a group of devices at the same time in one transmission. Delivery is managed by network switches and routers using various strategies to reduce duplication or redundancy and to effectively manage group membership changes to deliver the messages over each link of the network only once, and creating copies only when the links to the group of destinations split.
