Media streaming involves delivering multimedia content constantly to an end-user through streaming. There are two types: on-demand streaming and live streaming. On-demand streaming uses progressive streaming or downloading to allow users to watch content at any time, while live streaming uses true streaming to broadcast live events worldwide. Media streaming protocols include MMS, RTP, RTSP, and HTTP adaptive protocols for delivering large multimedia files, and compression techniques help reduce the bandwidth needed for streaming high quality audio and video content to viewers.

large
volume.

12. Streaming Media Storage
Calculation (for a single user and file)
● Storage size (in megabytes) =
length (in seconds) × bitrate (in bit/s) / (8 × 1024 × 1024)
● One hour of video encoded at 300 kbit/s (this is a typical
broadband video as of 2005 and it is usually encoded in a
320 × 240 pixels window size) will be:
(3,600 s × 300,000 bit/s) / (8×1024×1024) requires around 128
MB of storage.

13. Media Streaming
Compression
● Audio Compression Codec:MP3, Vorbis or AAC
● Video Compression Codec:H.264 or VP8
● Bit-Stream Containers:MP4, FLV, WebM, ASF or ISMA.
