Wanting to stream?
First consider these questions
– Do you want to stream audio or video?
– What content needs to be streamed? Pre-recorded archived content, live audio content or a combination of both?
– If the content to be broadcast is live, where and how can the live content be encoded?
– What is the duration of the Internet broadcast? 24/7 or specific to certain times of the day/night?
– Any indication of the stream quality expected? Will the audio content be voice or music-based?
– Do you have appropriate the rights to the distribution of the audio content?
– Any ideas of the target audience size?
– Any ideas of the ratio split of local vs international?
