HP-UX Multimedia Streaming Protocols (MSP) Programmer's Guide

• Multicast audio conference
• Audio and video conference
For information on RTP APIs, see “RTP Library” (page 19).
Real-Time Streaming Protocol
RTSP controls the transfer of real-time media data and serves as a network remote
control for multimedia services. The client requests a selected media file from the server
using RTSP. The server, in response, returns information required by the client to
transfer the data. Applications run RTSP on top of TCP.
For information on RTSP APIs, see “RTSP Library” (page 28).
Session Description Protocol
The Session Description Protocol (SDP) describes the general real-time multimedia
sessions. A multimedia client uses SDP to announce a conference session by periodically
multicasting an announcement packet to a familiar multicast address and port using
the Session Announcement Protocol (SAP).
SDP conveys information about media streams in multimedia sessions and allows the
recipients of a session description to participate in the session. SDP is normally used
in an Internetwork but can also be used for multimedia conferences in other network
environments.
For more information on SDP APIs, see “SDP Library” (page 67).
Files Provided with the MSP SDK
MSP is a Software Developer’s Kit (SDK) that contains C header files, C libraries, and
example programs. To install the SDK, you must download the SDK package from the
HP software depot web site at:
http://www.software.hp.com
Unpack the files to the directory of your choice. When you unpack the SDK depot, it
will create several directories and populate them with the various files provided with
the MSP SDK. The directories and files supplied with the SDK are detailed in the
following sections:
• “Include Files Supplied with the SDK for C” (page 16)
• “Libraries Supplied with the SDK for C” (page 17)
Include Files Supplied with the SDK for C
Table 1-1 lists the header files that the MSP SDK for C includes.
