Multimedia Features
PowerMedia HMP 4.1 supports H.264, MPEG-4, and H.263 video transcoding and video transrating for building applications such
as continuous presence video conferencing, video portals, and video streaming servers of different densities. PowerMedia HMP 4.1
also supports 3G-324M and video streaming, video transcoding, and audio transcoding (AMR-NB) capabilities for 3G applications.

also supports 3G-324M and video streaming, video transcoding, and audio transcoding (AMR-NB) capabilities for 3G applications.
In addition, PowerMedia HMP 4.1 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 network endpoints
3G network endpoints
•
Enhanced DVR controls such as pause, resume, and fast forward during the video playback operations
PowerMedia HMP 4.1 can also deliver only the audio portion of a video call to an audio-only endpoint for 3G/2G gateway
functionality.
functionality.
Security Features
PowerMedia HMP 4.1 includes security features using Secure RTP (SRTP) and SIP Transport Layer Security (TLS) to encrypt
media and signaling information and keep media transactions secure. Because 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.

Easy Migration to Hybrid TDM-IP and Pure IP Solutions
PowerMedia HMP 4.1 uses the host server’s built-in Network Interface Card (NIC) to enable IP connectivity, and supports the IETF
RFC 3261 SIP standard for voice and video call session establishment. When combined with DNI Boards for PSTN connectivity,
HMP 4.1 provides a cost-effective platform for building TDM solutions, and then later migrating them easily to hybrid platforms,
and finally to pure IP deployments. Hybrid platforms can be deployed as IP media gateways, enhanced service platforms, or
converged PBX solutions.

Interoperability
To provide the interoperability needed for high-quality media streaming with a wide variety of industry-standard IP gateways and
endpoints, PowerMedia HMP 4.1 supports RTP and RTCP protocols for streaming over IP using G.711 (frame size of 10 ms, 20
ms, or 30 ms), G.726, G.723.1, G.729ab, AMR-NB, and AMR-WB (G.722.2) and G.722.
