Announcement The following information applies to version 1.001 of the Multimedia Streaming Protocols (MSP) software on the HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3 operating systems. The MSP framework for HP-UX multimedia streaming servers comprises libraries required for implementing the MSP protocols and transmitting real-time data.
RTP consists of Real-Time Control Protocol (RTCP), a closely linked protocol, that provides a mechanism for reporting feedback on the transmitted real-time data. • RTSP Real Time Streaming Protocol (RTSP) controls the transfer of real-time media data and serves as a network-remote-control for multimedia services. • SDP Session Description Protocol (SDP) describes the general real-time multimedia sessions. See HP-UX Multimedia Streaming Protocols (MSP) Programmer’s Guide, available at http://www.docs.hp.
Table 1-1 Man Pages (continued) 10 Man Page Description rtp_recv(3n) Describes rtp_recv that receives RTP or RTCP packets from an RTP session. rtp_send(3n) Describes rtp_send that sends an RTP packet. rtsp Provides an introduction to the RTSP library. rtsp_alloc_cache(3n) Describes rtsp_alloc_cache that dynamically allocates memory for the rtsp_cache_t structure and initializes the structure members with application-specified values.
Table 1-1 Man Pages (continued) Man Page Description rtsp_free_session(3n) Describes rtsp_free_session that frees the dynamically allocated memory for the rtsp_session_t structure and its members. rtsp_free_session_flds(3n) Describes rtsp_free_session_flds that frees the dynamically allocated memory for the rtsp_session_t structure and its members. rtsp_free_xport_spec(3n) Describes rtsp_free_xport_spec that frees the dynamically allocated memory for the rtsp_xport_spec_t structure and its members.
Table 1-1 Man Pages (continued) 12 Man Page Description rtsp_init_session(3n) Describes rtsp_init_session that initializes the members of the rtsp_session_t structure with the specified values. rtsp_init_xport_spec(3n) Describes rtsp_init_xport_spec that initializes the members of the rtsp_xport_spec_t structure with the default values. rtsp_is_request_msg(3n) Describes rtsp_is_request_msg and rtsp_is_response_msg that check if an RTSP message is a request message or a response message.
Table 1-1 Man Pages (continued) Man Page Description sdp_get_media_info(3n) Describes APIs that get or set SDP structure members for media descriptions. sdp_init(3n) Describes sdp_init that allocates space and initializes the SDP structures, and sdp_free that frees the space allocated for the SDP structures.
