    About Program Dialing What Defines a Program? A Program configures a Tieline codec to send or receive one or more Audio Streams based upon the particular application the codec is being used for at any given time. Each audio stream within a program can be defined separately and contain a variety of settings relating to the number of connections (e.g.

    Merlin IP Codec User Manual Configuring Dual Mono Programs 14.4 A dual mono program allows a codec to create two simultaneous audio stream connections with different destination codecs. Configuring a program to dial two mono audio stream connections from a codec is very similar to creating a single audio stream connection.

  • Page 64: Configuring Sip Settings

    SIP provides superior interoperability between different brands of codecs due to its standardized protocols for connecting devices and is intended to be used when connecting Tieline codecs to non- Tieline devices. Devices primarily use SIP to dial another device’s SIP address and find its location with a minimum of fuss.
  • Page 65 SIP dialing is only supported over point-to-point connections, not multi-unicast connections. Tieline G3 codecs do not support connections using AAC and will default to MPEG Layer 2 if an incoming call is programmed to use this algorithm.

  • Page 77: Selecting An Algorithm

    Overview of Tieline Algorithms 1. The Tieline Music algorithm is optimized for audio bit rates as low as 19.2kbps with only a 20 millisecond encode delay. It offers 15 kHz mono from 24Kbps to 48Kbps. 2. Tieline MusicPLUS delivers up to 20 kHz mono from 48kbps upwards. It can also deliver up to 20 kHz stereo from 96kbps upwards, offering huge savings on your IP data bills and outstanding audio quality.
  • Page 78 For example, if MP2 algorithms are used, program delays will be much longer than when using Tieline Music or MusicPLUS algorithms. This is due to the additional inherent encoding delays involved when using MP2 algorithms. This can be a major consideration for live applications that integrate remotes into a broadcast.
  • Page 79: Configuring The Jitter Buffer

    Data packets travel independently and arrival times can vary greatly depending on network congestion and the type of network used, i.e. LAN versus wireless networks. The jitter-buffer is encompassed with Tieline's SmartStream IP technology which can: Remove duplicate packets.
  • Page 80 Merlin IP Codec User Manual Tieline codecs can be used to program either a fixed or automatic jitter buffer and the setting you use depends on the IP network you are connecting over. Over LANs, WANs and wireless networks the automatic jitter buffer generally works well. It adapts automatically to the prevailing IP network conditions to provide continuity of audio streaming and minimises delay.
  • Page 81 4. Stage 4 “live” (A): This is where the codec determines it is safe enough to start broadcasting using the auto-jitter buffer level. We recommend running the codec for a few © Tieline Pty. Ltd. 2012...
  • Page 82 FEC is being used. Fixing Jitter Buffer Settings The default jitter-buffer setting in Tieline codecs is 500 milliseconds. This is a very reliable setting that will work for just about all connections. However, this is quite a long delay and we recommend that when you set up an IP connection you test how low you can set the jitter-buffer in your codec.

  • Page 84 FEC according to the available uplink bandwidth at each end for best performance. As an example, if you want 15 kHz mono (using the Tieline Music Algorithm) you will need at least a 24kbps connection for audio. Adding 100% FEC will add another 24kbps making your bit rate 48kbps plus some overhead of around 10kbps is required.
