Full Streaming Flash Compatibility Real-Time Messaging Protocol (RTMP) Wowza Media Server Pro implements RTMP to achieve real-time interaction between Wowza Media Server Pro and the Flash client. It supports the five variants of RTMP – RTMP, RTMPE (encrypted RTMP), RTMPT, RTMPTE (encrypted RTMPT) and RTMPS (RTMPT over SSL). RTMP is the base protocol and is the most efficient and fastest of the five variants. RTMPT is a tunneling variant of the RTMP protocol that can be used to tunnel through firewalls that employ stateful packet inspection. RTMPE and RTMPTE are encrypted variants of the RTMP and RTMPT protocols that secure the data being transmitted between the Flash player and Wowza Pro. Real-Time Streaming/Transport Protocols (RTSP/RTP) Wowza Media Server Pro supports the Real-Time Streaming Protocol (RTSP) and Real-time Transport Protocol (RTP) for incoming streaming of H.264/HE-AAC content. This enables the use of non-RTMP based live media encoders with Wowza Pro. These streams are then translated as needed for delivery to the Flash player client over RTMP. For the most up to date listings and instructions for supported RTSP/RTP encoders visit Wowza Media Server Forums: Live Encoders.

MPEG Transport Stream (MPEG-TS) The Wowza Media Server Pro Unlimited with MPEG-TS edition additionally supports MPEG Transport Streams (ISO 13818-1, H.222.0, MPEG-TS) for incoming streaming of H.264/HE-AAC content. This enables the use of MPEG-TS live media encoders commonly deployed in broadcasting, cable, satellite, IPTV and other infrastructures . These streams are then translated as needed for delivery to the Flash player client. For details on MPEG-TS encoders support visit Wowza Media Server Forums: Live Encoders. Remote Shared Objects (RSO) Wowza Media Server Pro implements the server component of Remote Shared Objects. Remote Shared Objects are an extension of ActionScript objects that allows the sharing of object data between Flash movies on the same or different client machines, or for persistent maintenance of data across client sessions. Flash Players and Codecs Wowza Media Server Pro is compatible with standard Flash players 7, 8 & 9 and supports the same method as FMS for making client to server calls. It works with all traditional Flash codec variants including Sorenson Spark and On2 VP6, including On2 Flix® Live, Flix Publisher Live, and hardware accelerated implementations of VP6 from a number of vendors. In addition, Wowza Media Server Pro supports H.264 video and HE-AAC audio streaming to the Flash player 9 (9,0,124 or later). For live H.264/HE-AAC streaming, Wowza Pro supports a broad range of standards-based RTSP/RTP and MPEG-TS encoders. For details on supported encoders visit Wowza Media Server Forums: Live Encoders. Supported Video and Audio File Formats Wowza Media Server Pro can stream video and audio content in Flash video format (.flv), H.264/ HEAAC media format (.f4v, .mp4, .m4a, .mov, .mp4v, .3gp, and .3g2) and MP3 format (.mp3). The server supports the streaming of all variants of video, audio and metadata that can be stored in a Flash video file as well as the MP3 ID3 tags stored in an MP3 audio file. Additionally, Wowza Pro fully supports AAC metadata.

Expanded Functionality H.264/HE-AAC Streaming with Non-Flash Encoders (RTSP/RTP & MPEG-TS) One of the exclusive features of Wowza Media Server Pro is the capability to support the Real-Time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP) and MPEG Transport Streams (MPEG-TS) for incoming streaming of H.264/ HE-AAC content. This enables the use of live encoders such as Vara Software Wirecast, Apple QuickTime Broadcaster, HaiVision, Scopus and many others. This capability eliminates the need for live H.264 encoders to support a proprietary RTMP protocol, makes it easy to repurpose exiting encoders for streaming H.264/HE-AAC content to Flash, and protects exiting investment in the H.264 encoding infrastructure. TCP, UDP and multicast from RTSP/RTP and MPEG-TS encoders is supported. Wowza Pro also works with H.264 encoders that use RTMP.

MP3/HE-AAC SHOUTcast/Icecast content re-streaming to Flash Streaming Security One of the main advantages that streaming media has over progressive download is content protection and security. However, simply streaming your content to the Flash client does not always provide sufficient security against content intrusion, unauthorized diversion of streams and stream ripping. Wowza Pro provides several levels of protection to help guard your content against these threats through content URL protection, trusted domains and link encryption (RTMPS, RTMPE, RTMPTE). In addition, a SecureToken example that ships with Wowza Pro offers a high level of content protection August 2008

against spoofing threats like those posed by the Replay Media Catcher and similar streaming media interceptors. Fast Forward, Fast Rewind and Slow Play This unique TiVo®-like feature of Wowza Media Server Pro provides viewers of pre-recorded Flash (.flv) video with the familiar experience of using a DVR. A user can fast forward or rewind the video at different pre-set speeds, for example at 4X, 15X, or 60X. This features significantly improve user experience in e-learning and on-line training applications, or when viewing the long format movies. A slow play (slow motion) option is also available. This is a useful feature in applications such as football game reviews by caching staff. A Flash player example with Fast Forward and Rewind features is included with Wowza Media Server Pro download. Live Stream Recording Wowza Media Server Pro allows you to instantly record live video/audio content into an .flv file from a video device, such as webcam video captured by the Flash player. This feature is particularly useful for applications requiring content archiving or later replay. For example, live stream recording can be used in an educational environment to record live lectures and make them instantly available as on-demand e-learning content. Wowza Media Server Pro records live streams in their original encoded format (i.e., On2 VP6 or Sorenson Spark). Customizable Media Reader/Writer Wowza Media Server Pro expands the range of readable/writable media types beyond the traditionally supported flv and MP3 formats in Flash to H.264 and HE-AAC, and features a unique media reader/writer that can be configured for custom extensions for any media type. Future Extensibility Wowza Media Server Pro features a flexible custom module interface (API) which can be used to create custom stream types and extend server functionality with custom modules directly callable by the Flash player client. Custom modules are a replacement for the FMIS server-side scripting capabilities. Embedding Potential Wowza Media Server Pro is implemented to be tight, small and embeddable. Its compact size offers an opportunity to expand the applications for the Wowza Media Server Pro technology beyond the data center. The Wowza Media Server Pro technology can be embedded with other software products and in various devices, such as set-top boxes, network appliances, TelePresence systems, mobile and consumer devices to enable a variety of new rich media streaming applications.
