ATSC: Advanced Television Systems Committee.
ASI-IP-GTW User's Manual format. Three versions exist. IGMPv2 is common today but IGMPv3 is the next step. Meta-data: Meta-data is descriptive data that is "tagged" to a movie or audio clip. Meta-data is essential for the broadcaster. MPEG2: Moving Picture Experts Group 2. The compression standard used today on most satellite and cable TV digital broadcasts. MPLS: Multi-protocol Label Switching.
ASI-IP-GTW User's Manual SDP: Session Description Protocol. A protocol to signal multicasts in a network. SDP is used as a mechanism to describe an ongoing multicast; for example the type of compression used, IP addresses etc. SDTI: Serial Data Transport Interface. A mechanism that allows transmission of various types of data over an SDI signal. This may be one or more compressed video signals or other proprietary data types.
ASI-IP-GTW User's Manual Unicast: Point-to-point connection, i.e. the "opposite" of multicast which is one to many (or many to many). In this mode, a transmit unit sends video data direct to a unique destination address. VLAN: Virtual LAN, a network of units that behave as if they are connected to the same wire even though they may actually be physically located on different segments of a LAN.

ASI-IP-GTW User's Manual 10 Appendix D: Upgrade of Features The ASI-IP-GTW ASI to IP Video Gateway encompasses software licensing of functionality. This appendix describes how to upgrade the product features with the software feature system. Customers who purchase "base" software licenses may wish to increase their software functionality or feature set at some point. A feature license conveys the right to use a feature, but cannot add a feature to a software release that does not support it.
ASI-IP-GTW User's Manual Figure 38 shows the feature upgrade page. Please paste in the license key in the "Activate feature key" field and press the button "Activate feature key" to load a new feature key for the unit. Figure 38. Feature upgrade page Note: Remember to include the dashed line before and after the encrypted contents. The dialogue shown in Figure 39 will appear when a valid license key is downloaded to the unit.
ASI-IP-GTW User's Manual Figure 39. Feature upgrade dialogue Note: Please observe that you have to switch off and on the unit to active the new keys. In addition to the feature upgrade field, the Upgrade-page contains information about the unit and currently enabled features. The license files already entered to the unit are listed under current license files. A license key can contain license to one or more features.
ASI-IP-GTW User's Manual 11 Appendix E: Upgrading Software SW loading can be performed from the bottom of the /upgrade page, as shown in Figure 40. This option is available on SW versions 1.3.0 and above. To load SW on older SW versions, please refer to documentation on how to load SW by FTP. Press the ‘Browse’ button and select the file to load to the device. The file must have the filename extension ‘.out’. Then press the ‘Upload Software’ button to start the SW loading.
ASI-IP-GTW User's Manual Figure 41 SW load progress When the file is transferred, a status message is printed in the main browser window. If the loading was successful, the device is automatically rebooted to start the new SW. Figure 42 SW load status Please remember to verify the new SW version on the ‘Device Info’ page after the device has re-booted.
ASI-IP-GTW User's Manual 12 Appendix F: Quality of service – Setting Packet priority Normal IP routing is by best effort. This does not work well for broadcast television as the video and audio components needs to be transport as a continuous flow of packets without inference caused by other traffic over the internet. There are different techniques to secure a high quality of service. The main ones are: o MPLS (Multi Protocol Label Switching) o Layer 3 routing priority o Layer 2 routing priority 12.
ASI-IP-GTW User's Manual 1.1.1.37 ASI-IP-GTW Configuration The number entered into the Type of service (TOS) field on ASI-IP-GTW IP TX configuration menu defines all 8 bits. The value used should be in accordance with traffic engineering policy of network and should be in the range from 0 to 255. 12.3 Layer 2 priority Prioritisation can also be supported at layer 2 for the case when VLAN tags. The 802.1q VLAN tag has 3 bits for setting the Class of Service (COS). The operation is further defined in 802.
