I thought JMF 1.0 only supports playback of media from a network source. But then i came through this power point which says that, it supports RTP but receive only. I am confused, what does this mean ? does this mean that a JMF 1.0 client player does support receiving and playing of real time media. However, it does not support transmitting RTP data. I did search a lot about this topic and did not found a whole lot. I have read the JMF 2.0 spec but did not found any answer related to this topic. I haven't found JMF 1.0 spec yet and would really appreciate if some could explain this topic.
