How to operate RTP of ALTIPHID header in video server

摘要

The present invention relates to a method of operating an RTP of an ALTP header in a video server. In the related art, in the binding process of an RTP session and an SSRC, the RTP session waits until an RTP packet arrives and then binds the RTP. There is a problem in that all Altippi packets that arrive before the packet arrives are lost, and when the Altipi data packets are bound in sequence when two arrive, the Altipi data packets arrive when the two do not arrive sequentially. There is a problem that all of them are lost. Accordingly, the present invention provides a first step in which an arbitrary session is opened when a service request is received from a client in an initial state of the server, and sends an RTCP-APP packet for SSRC binding to the client in the open state. A second step of binding and a play request for a session opened in the second step in which the binding is made, and the media data is loaded into an RTP packet having the SSRC bound in the second step. In order to prevent the loss of media data that is initially lost, the RTCP packet is sent before the RTP packet in the open state before play so that it can be bound to the client's RTP session before the media data is transmitted. Load media data into bound RTP packets to prevent data loss Will.
