Chapter 4 Configuring Applications Applications Overview Chapter 4 Configuring Applications 4.1 Applications Overview NSG 9000-6G operates in the following applications: VOD Application - The system serves as a highly integrated digital video gateway, capable of multiplexing on-demand content streamed over an IP network. Broadcast Applications- The system serves as a digital video gateway that passes through streams. In addition it can broadcast remuxed services and PIDs. SDV Application - The device streams out SDV sessions provisioned by the NGOD ERM or ISA. M-CMTS Application - NSG 9000-6G supports wideband M-CMTS data PIDs. As part of the M-CMTS system, NSG 9000-6G processes down streams and improves downstream data rates by significantly reducing costs. D2E Application - NSG 9000-6G supports Multicast IP down streams encapsulated as DOCSIS 3.0 with DBC requests (when required) on dedicated frequencies (D2E server frequencies). CAS - This version supports Privacy Mode scrambling only. NOTE: When provisioning static sessions through the web client or MCT, NSG 9000-6G may carry up to 500 sessions only. When dynamic sessions are provisioned through NGOD ERM, ISA SRM or VOD SRM, NSG 9000-6G may carry up to 3,000 dynamic SDV/VOD sessions. 4.2 VOD Application The VOD application includes two tabs: • Settings - allows you to set the following: General parameters - session inactivity time MPEG related parameters Emulation mode • QAMs - a read only page to view QAMs settings 4.2.1 Defining Session Inactivity Time Define the allowed duration for session inactivity before the session is removed from the output. © 2012 Harmonic Inc. 74 NSG 9000-6G, Version 2.7, Rev B
Chapter 4 Configuring Applications VOD Application 1. Select Applications > VOD > Settings tab. Define session inactivity time 2. In Session Inactivity Teardown Threshold (Sec), enter the allowed period of time in seconds for session inactivity. In case the interval is longer than the indicated time, the session is removed from the output port. 3. By default Allow Auto Detection is selected. Verify that this option is selected to allow auto detection, in the input, of the output QAM according to the indicated UDP port. 4.2.2 Defining MPEG Parameters 4.2.2.1 PID Remapping The PID Remapping option allows you to remap according to a specific paradigm or randomly. In either case, the NSG prevents the assignment of conflicting PIDs. • Paradigm - The elementary stream PIDs are determined according to the ATSC A/53 standard, which defines the PID remapping rules that are listed in the table below: Formula Service ID = 0xN PMT PID = LeftShift (N) = 0xN0 PCR=Video=PMT+1= 0xN1 Audio 1&2 = PMT+ 4/5 = 0xN 4,0xN5 ECM=PMT+9= 0xN9 Example Service ID = 0x34 PMT PID = 0x340 Video = 0x341 Audio 1&2= 0x344, 0x345 ECM PID= 0x349 NOTE: The Paradigm mode is not suitable for processing services with service IDs greater than 510. If you are using service ID that are greater than 510 you must use the Random mode. • Random - The NSG remaps incoming PIDs to PID numbers that are randomly selected from a predefined range. Define the range in the PID Range field. The PID range is written in hex-decimal format. Range of acceptable values is 0x21 to 0x1FF0. Changing the PID remapping mode may interrupt the streams currently flowing through the device. It is recommended to change the remapping mode only when no active streams are flowing through the device. In addition, changing the PID remapping may affect the operation of some STB (Set-up Boxes.) Various STBs operate better with a specific mode. If you suspect such a case, call the STB vendor before changing the PID remapping. © 2012 Harmonic Inc. 75 NSG 9000-6G, Version 2.7, Rev B
