Overview:

Dialogic PowerMedia HMP for Linux (HMP Linux) is scalable, feature-rich multimedia processing software for building innovative and cost-effective voice and video solutions suitable for enterprise or service provider deployment. HMP Linux can enable basic SIP or hybrid connectivity, audio and video play/record, multimedia streaming, transcoding, fax, automated interactive audio and video solutions (IVR and IVVR), and complex live interactions, such as contact centers and audio and video conferencing or video portals. With HMP Linux, Dialogic brings decades of media processing and signaling development experience to a pure software media engine, allowing developers to transition many existing Dialogic hardware-based applications to software-based IP-enabled solutions, or create completely new mobile interactivity and other multimedia applications.

HMP Linux includes H.264 and VP8 video support up to HD720p resolution, continuous presence video conferencing, HD Voice with G.722, AMR Wideband (G.722.2), and OPUS codecs, media server virtualization, and scales up to 5000 SIP connections and 2000 conference parties. HMP Linux also contains patented and patent-pending software that enhances video quality through improved bit-rate control and dynamic feedback algorithms. HMP Linux runs on general-purpose servers without the need for specialized hardware. Along with virtualization support, this reduces total cost of ownership and provides greater efficiency and deployment flexibility. Adding Dialogic HMP Interface Boards (DNI Boards) allows PSTN connectivity in a “single box” solution with gateway functionality. Programming interfaces for HMP Linux include Dialogic R4 and Global Call APIs for low-level media and signaling control.

How PowerMedia HMP Linux Works

HMP Linux performs media processing tasks on general-purpose processors running on common server architecture without requiring specialized hardware. HMP Linux provides media services and functionality for building flexible, scalable, and cost-effective converged telephony applications, next-generation multimedia servers and gateway solutions for TDM, IP, 3G/4G wireless and IMS networks. HMP Linux is complimented by support for other Dialogic products and technologies, including:

  • Dialogic Global Call and R4 APIs — enables existing applications written for other Dialogic products (for example, board products) to move easily from TDM to IP and to HMP Linux.
  • Dialogic HMP Interface Boards (DNI Boards) — enables PSTN (T1/E1) connectivity in a variety of densities
  • Dialogic DSI SS7 Boards, Dialogic DSI Signaling Servers, and Dialogic DSI Protocol Stacks
    – provides TDM or IP SS7 interfaces using Global Call API for SS7 Signaling
    – supports single-server solutions, such as for pre-paid wireless and CRBT

Security Features

HMP Linux includes security features using Secure RTP (SRTP), DTLS-SRTP and SIP Transport Layer Security (TLS) to encrypt media and signaling information and keep media transactions secure. Because SRTP and DTLS-SRTP provides encryption, message authentication and integrity, and replay protection for RTP data, conversations are secure and cannot be stolen for later playback. TLS prevents the theft of dialing information on outbound calls because it secures SIP signaling information.

Multimedia Features

HMP Linux supports video transcoding and video transrating for building applications such as continuous presence video conferencing, video portals, and video streaming servers of different densities. Video codecs supported include H.264 and VP8 (up to HD720p resolution at 2Mbps) as well as MPEG-4 and H.263 (up to CIF resolution, 30fps and 384kbps). IP video endpoints can be inter-connected with transcoding between a supported codec or in a pass-through (native) mode using the same video codec. HMP Linux also supports video streaming, video transcoding, and audio transcoding (AMR-NB and AMR-WB) capabilities for 3GPP wireless applications and can deliver only the audio portion of a video call to an audio-only endpoint for gateway functionality between multimedia endpoints.

In addition, HMP Linux supports:

  • Initiation and termination of a multimedia (audio/video) call, which includes SIP-based call control
  • Synchronization of voice and video streams for playback on IP video phones, video-enabled soft clients, and connections to 3G/4G network endpoints
  • Enhanced DVR controls such as pause, resume, and fast forward during video playback operations

Easy Migration to Hybrid TDM-IP and Pure IP Solutions

HMP Linux uses the Ethernet Network Interface Card (NIC) typically present in host server platforms to enable IP connectivity, and supports the IETF RFC 3261 SIP standard for voice and video call session establishment.

When combined with Dialogic HMP Interface Boards (DNI Boards) for PSTN connectivity, HMP Linux provides a cost-effective platform for building TDM solutions, and then later migrating them easily to hybrid platforms, and ultimately to pure IP deployments. The DNI Boards are software-selectable T1 and E1 trunks supporting a range of PSTN protocols, including ISDN and CAS. Hybrid platforms can be deployed as IP media gateways, enhanced service platforms, or converged PBX solutions.

To help customers accelerate their time-to-market and migrate existing applications to IP, HMP Linux supports two direct APIs: the Dialogic® R4 API for media processing and the Dialogic Global Call API for call control. Because these APIs are consistent with the APIs for Dialogic boards with DM3 architecture, Dialogic customers can facilitate quick application development and easy migration from a board-based platform to a platform based on HMP Linux.

Interoperability

To provide interoperability for high-quality media streaming with a wide variety of IP gateways and endpoints that comply with IETF and ITU standards, HMP Linux supports RTP/RTCP protocols for streaming over IP using G.711, G.726, G.723.1, G.729, iLBC, GSM-FR, GSM-EFR, AMR-NB, AMR-WB (G.722.2), G.722 and OPUS.

To further provide high voice quality and low latency, HMP Linux supports:

  • Threshold alarms
  • Packet loss reduction/concealment
  • RTP and RTCP timeouts
  • Type Of Service (TOS) byte setting
  • Detection and reporting of timeouts in RTP and RTCP sessions to applications

To enable advanced network QoS monitoring and analysis, HMP Linux supports High Resolution RTCP (RTCP-HR) reports for applications that require extended data assessments of VoIP delivery within the network.

Conferencing

Conferencing features in HMP Linux facilitate the development of advanced multimedia conferencing applications. These features include:

  • Coaching and Whisper Conferencing

Configurations:

Applications developed on HMP Linux often serve as a voice or video IP Media Server, a network entity that terminates IP signaling and media connections in a network, which can be deployed differently in service provider and enterprise environments. Configurations for IP media servers that can be developed with HMP Linux include video transcoding gateway, video transcoding media server, video portal, network announcement, IVR, voice mail, and conferencing server.

Service Provider Configuration

Figure 1 illustrates how an IP media server based on HMP Linux can be deployed in a typical service provider environment to deliver messaging, IVR, announcements, voice mail, speech, or conferencing applications.

HMP Linux also enables video versions of many of these applications. An IP-PSTN gateway terminates PSTN connections, and a softswitch manages all aspects of call establishment and teardown over IP. Once the call is established, an RTP connection is created between the IP media server and an endpoint. The softswitch tells the media server, IP endpoints, and IP-PSTN gateway when to establish or drop connections.
