  • Page 22: Mixing Facilities

    INTRODUCTION ORBAN MODEL 1010 Mixing Facilities: In addition to sound card and audio processing functionality, Optimod-PC is also a capable mixer, having one stereo analog input, two AES3 / SPDIF digital inputs (which can accept any sample rate from 32 to 96 kHz), and one WAVE input (to ac- cept Windows sound sources), all of which can be mixed.

  • Page 23: About Perceptual Coders

    OPTICODEC-PC INTRODUCTION About Perceptual Coders CD-quality audio (16-bit words at 44.1 kHz sample rate) requires 705,600 bits per second per channel, which is far too high for economical streaming. Perceptual cod- ing reduces the number of bits per second necessary to transmit a high-quality audio signal.

    1-10 INTRODUCTION ORBAN MODEL 1010 distortion, or like warbling, comb filtering, or gurgling—an “underwa- ter” sound. Coding Efficiency Different sounds will vary greatly in the efficiency with which a perceptual coding system can encode them. Therefore, for a constant transmission bitrate, the mask- to-noise ratio will constantly change.

    1-11 OPTICODEC-PC INTRODUCTION AAC does not stand for Apple Audio Codec, although Apple was one of the first to implement this technology with the introduction of Apple iTunes and QuickTime 6. The Coding Technologies “Spectral Band Replication” (SBR) process can be added to almost any codec.

    1-13 OPTICODEC-PC INTRODUCTION A low-bandwidth signal in the compressed bit stream provides “hints” to modulate these created high frequencies so that they will match the original high frequencies as closely as possible. Adding SBR to the basic AAC codec creates aacPlus, which of- fers the best subjective quality currently available at bitrates below 128 kbps.

  • Page 28: Cascading Codecs

    1-14 INTRODUCTION ORBAN MODEL 1010 Cascading Codecs There are two general applications for codecs in broadcasting — “contribution” and “transmission.” A contribution-class codec is used in production. Accordingly, it must have high enough “mask to noise ratio” (that is, the headroom between the actual...

  • Page 29: Networking

    1-15 OPTICODEC-PC INTRODUCTION Networking Opticodec-PC supports both unicast and multicast streams. Each method has its own advantages and your streaming application will determine which one to use. To connect to the Internet using unicast, a server is required. This receives the out- put of the encoder and creates the streams to which your listeners connect.

  • Page 30: Bandwidth Requirements

    E-3 or T-3 lines, or even higher capacity to serve. Large streams may even require more than one server to handle the necessary network throughput. However, since Orban Opticodec-PC is bandwidth efficient, you are able to serve a larger audience at a lower cost of operation with higher audio qual- ity than with inferior older generation codecs.

  • Page 31: Streaming Architecture

    Live events, such as radio broadcasts, concerts, speeches, lectures, and sporting events are commonly streamed over the Internet as they happen with the assistance of broadcasting encoding software such as Orban Opticodec-PC Streaming Encoder. The broadcasting software encodes a live source, such as studio originated audio, in real time, and delivers the resulting stream to the server.

  • Page 32: Overview Of Streaming Architecture

    1-18 INTRODUCTION ORBAN MODEL 1010 Overview of Streaming Architecture There are several ways to stream content over a network. This can be confusing at first, because some of these ways are only slightly different from others. The termi- nology associated with them and the names that commonly refer to them can be equally confusing.

  • Page 33: Streaming Server Advantages

    1-19 OPTICODEC-PC INTRODUCTION network transports and protocols used with their associated servers. Streaming Server Advantages Streaming servers open a dialog with the media player. There are two sides to this dialog — one for passing control messages between the media player client and the server and one for transferring the media content.

  • Page 34: Rtsp/Rtp - Streaming Servers

    1-20 INTRODUCTION ORBAN MODEL 1010 • No special server software is required. Your web server software can deliver media content. • Files downloaded to the user’s computer can be used later without additional network connectivity. • Media content downloads to the user’s computer as fast as the network con- nection will allow.

  • Page 35: Figure 1-5: Qtss/Dss Server/Client Transports

    1-21 OPTICODEC-PC INTRODUCTION • Optional Reliable UDP, if supported by the client player, can be used for a higher level of retransmission of lost packet control than TCP/IP. • Firewalls and/or routers can stop UDP/IP. • RTP can be interleaved with the RTSP control connection, which uses TCP/IP. This can get through firewalls that block UDP/IP.

  • Page 36: Http/Icy - Streaming Servers

    1-22 INTRODUCTION ORBAN MODEL 1010 • A special HTTP tunneling protocol that wraps RTSP/RTP packets inside HTTP packets, only supported by Apple QuickTime Player, can be used to help cir- cumnavigate firewalls and/or routers by using the same port that web serv- ers/browsers use.

  • Page 37: Http - Web Servers

    1-23 OPTICODEC-PC INTRODUCTION & & Figure 1-7: Icecast2 Server/Client Transports HTTP — Web Servers HTTP on web servers has the following properties: • It is commonly called a fast start or progressive download stream. • HTTP uses TCP/IP protocol to ensure that all streaming packets are delivered, retransmitting if necessary.

  • Page 38: Unicast

    1-24 INTRODUCTION ORBAN MODEL 1010 & Figure 1-8: Web Server/Client Transports Unicast In a unicast, each user or player client initiates its own stream, resulting in several one-to-one connections between client and server, which is less efficient use of bandwidth. Many clients connected via unicast to a stream in a local network can result in heavy network traffic.

  • Page 39: Multicast

    1-25 OPTICODEC-PC INTRODUCTION Multicast In a multicast, a single stream is shared among the player clients. Although this tech- nique reduces network congestion, it requires a network that either has access to the multicast backbone (otherwise called the Mbone) for content generally distrib- uted over the Internet, or is multicast-enabled for content distributed within a con- tained private network.

  • Page 55: Encoder Destination Server Parameters

    OPTICODEC-PC CONFIGURATION — STREAMING ENCODER Any encoder running on a separate computer from QTSS/DSS requires QTSS/DSS au- thentication to connect. Encoder users and access must be configured on the streaming server. Do this by adding QTSS/DSS users and allowing them server write access. If the streaming server has not been configured, refer to the Section 4: Streaming Servers (starting on page 4-1) for more information.

  • Page 56: Multicast - Rtsp/Rtp Darwin Streaming Server

    CONFIGURATION — STREAMING ENCODER ORBAN MODEL 1010 Multicast – RTSP/RTP Darwin Streaming Server A server is not required for multicast operation. Opticodec-PC provides an internal multicast server. Currently, the only multicast compatible client player with Optico- dec-PC is Apple QuickTime. At this time, it only supports AAC, not HE AAC/aacPlus.

  • Page 57: Multicast Relay

    OPTICODEC-PC CONFIGURATION — STREAMING ENCODER Note the case sensitivity in the URL. Multicast Relay Relaying a multicast stream requires a multicast enabled network and an RTSP/RTP server such as QuickTime Streaming Server or Darwin Streaming Server. Configure Opticodec-PC to supply a unicast stream to the streaming server; the streaming server handles the multicast.

  • Page 58: Unicast - Http/Icy Shoutcast

    CONFIGURATION — STREAMING ENCODER ORBAN MODEL 1010 Unicast — HTTP/ICY SHOUTcast Because Nullsoft Winamp, the primary player for Icecast2 streams, supports for HE AAC/aacPlus v2, we recommend using a Channel setting of Stereo v2. This will pro- vide the best codec performance at low bitrates.

  • Page 59: Firewall Considerations

    OPTICODEC-PC CONFIGURATION — STREAMING ENCODER Firewall Considerations Most hardware firewalls and routers will automatically open the necessary out- bound ports. Opticodec-PC Streaming Encoder uses TCP/IP for all server connections, so there should be nothing to configure in the firewall and/or router. In the event that outbound ports are blocked or a software firewall is used, the appropriate ports will require opening.
