  • For example, a producer could map a Ford logo onto an actor&apos;s shirt. The actor could be a clickable object within the movie. As you&apos;re watching, you could click the actor, and information about purchasing Ford merchandise would pop up on the screen. Motorola and Mitsubishi both recently displayed prototype cell phones that could play PacketVideo&apos;s content. As these prototypes become real products and the technology improves, you&apos;ll be able to get interactive video wherever you go.

    7. 7. Streaming Media
    8. 8. How does it work? <ul><li>File encoded and compressed to a smaller file </li></ul><ul><li>Break it into small packets </li></ul><ul><li>Send them one after the other </li></ul><ul><li>When the packets reach their destination, they are decompressed and resembled into a form that can be played </li></ul><ul><li>Playing a music or video file as it is downloaded from the internet. </li></ul><ul><li>Copy is never stored on the user’s computer. </li></ul>
    9. 9. How does it work? (Cont) <ul><li>To maintain the seamless play the packets are buffered </li></ul><ul><ul><li>Process by which the media player downloads a few seconds of the media file prior to actual playback. </li></ul></ul><ul><ul><li>Allows for uninterrupted playback as when buffer plays more packets are downloaded and queued for playback </li></ul></ul><ul><li>Streaming can be opened before a download is complete </li></ul><ul><ul><li>Organised to be rendered ASAP </li></ul></ul><ul><ul><li>Play as data is received </li></ul></ul>
    10. 10. Open Connection <ul><li>Streaming media files maintain an open connection </li></ul><ul><li>Media server and media client negotiate connection </li></ul><ul><li>Sent over the connection until the entire file has been received </li></ul><ul><li>Media clients play data over the open connection </li></ul><ul><li>Is buffered to overcome congestion </li></ul>
    11. 11. How do you stream? Encoder Media Server Internet
    12. 12. How Does Streaming Work? 2 2 Web Server returns location of media file 1 User clicks on stream link 1 3 Media player is launched 3 5 5 Media server sends stream to media player 6 Media player decompresses and plays stream Web Server 4 Media player requests media file from media server 4 Media Server
    13. 13. Playback Rates <ul><li>Streams can be encoded and downloaded at different bit rates. </li></ul><ul><li>Measured in kbps (kilobits per second). </li></ul><ul><ul><li>128 kbps is considered to be CD quality when using special codecs. </li></ul></ul><ul><ul><li>1-2Mbps is considered to be DVD / Broadcast quality. </li></ul></ul><ul><li>User’s bandwidth determines that maximum bit rate that can be played. </li></ul><ul><li>Can select the usual connection speed or give various options </li></ul>
    14. 14. Encoding <ul><li>The process of digitizing and compressing a piece of traditional media into a format capable of being broadcast over the internet and played by a computer </li></ul><ul><li>Raw data is typically uncompressed </li></ul><ul><ul><li>Big files - Contains all data essential to proper play </li></ul></ul><ul><li>Raw data is then encoded (compressed) to stream </li></ul><ul><ul><li>Encoders use audio and video codecs to compress data </li></ul></ul><ul><li>Compression is different for audio and video </li></ul>
    15. 15. Codecs <ul><li>Stands for Compression and Decompression </li></ul><ul><li>Compresses multimedia content prior to transmission, and decompresses upon playback. </li></ul><ul><li>This uses less bandwidth and increases playback speed. </li></ul><ul><li>Users must have the proper media player to stream each format. </li></ul>
    16. 16. Sound/Music Codecs <ul><li>MPEG-1 layer 3 (MP3) </li></ul><ul><ul><li>8 to 256kbs </li></ul></ul><ul><li>Qdesign (Quicktime) </li></ul><ul><ul><li>Basic – 8 to 48kbs </li></ul></ul><ul><ul><li>Pro – 4 to 128kbs </li></ul></ul><ul><li>MPEG4 (v1,v2,v3,v7) </li></ul><ul><ul><li>2kbs to 2mbs </li></ul></ul>
    17. 17. Video Codecs <ul><li>Real Video G2 </li></ul><ul><ul><li>Low motion, low bit rate </li></ul></ul><ul><li>MPEG4 </li></ul><ul><ul><li>High quality images, low and high bit rates </li></ul></ul><ul><ul><li>Moving towards MPEG4 based standards </li></ul></ul><ul><li>Apple Video </li></ul><ul><ul><li>Low quality but fast </li></ul></ul>
    18. 18. MPEG <ul><li>MPEG ( Moving Picture Experts Group ) , develops standards for digital video and digital audio compression. </li></ul><ul><li>MPEG-1 was designed for coding progressive video at a transmission rate of about 1.5 million bits per second. It was designed specifically for Video-CD and CD-i media. </li></ul><ul><li>MPEG-1 audio layer-3 (MP3) has also evolved from early MPEG work. </li></ul>
    19. 19. MPEG (Cont) <ul><li>MPEG-2 was designed for coding interlaced images at transmission rates above 4 million bits per second. </li></ul><ul><li>MPEG-2 is used for digital TV broadcast and DVD. An MPEG-2 player can handle MPEG-1 data as well. </li></ul><ul><li>A proposed MPEG-3 standard, intended for High Definition TV (HDTV), was merged with the MPEG-2 standard </li></ul>
    20. 20. MPEG4 and beyond…. <ul><li>The standard for multimedia for the web and mobility. </li></ul><ul><li>MPEG-4 is able to throw away a lot more information and to save files 8 to 12 times smaller than those of MPEG-2. </li></ul>
    21. 21. MPEG-4 <ul><li>Real power of MPEG-4 is the interactivity that can built into the video file or stream. </li></ul><ul><li>Multimedia producers and software and game developers can isolate parts of the video for particular special effects. </li></ul><ul><li>Pocket PC devices, and Windows CE already play back MPEG-4 and related codecs. </li></ul><ul><li>PacketVideo has a whole Web site full of short videos you can download wirelessly to your Pocket PC. </li></ul>
    22. 22. Packet Video
    23. 23. Encoding Streaming Video <ul><li>Choice of formats </li></ul><ul><ul><li>Real Video (Helix 10) </li></ul></ul><ul><ul><li>QuickTime </li></ul></ul><ul><ul><li>Windows Media (Version 10) </li></ul></ul><ul><ul><li>Flash Video Streaming (New up and coming) </li></ul></ul>
    24. 24. Choice of delivery speeds <ul><li>What connection are you streaming to? </li></ul><ul><ul><li>Dial up modem (56Kbps) </li></ul></ul><ul><ul><li>ISDN/Dual ISDN (64/128Kbps) </li></ul></ul><ul><ul><li>Cable 128 up to 20 Mb per sec </li></ul></ul><ul><ul><li>ADSL (copper twisted pair up to 2Mbs at least) </li></ul></ul><ul><ul><li>T-1 (1.5Mb’s) T-3 45Mbps’s </li></ul></ul><ul><ul><li>E-1 (more commonly called 2Mbps pipe) </li></ul></ul>
    25. 25. Considerations for streaming <ul><li>Movie size – size affects bandwidth </li></ul><ul><li>Frame rates – broadcast TV is 25fps most webcasts are lower </li></ul><ul><li>Is it audio, video or both </li></ul><ul><li>Encoding the media – which format </li></ul><ul><li>Making a website which is suitable to play a streaming file. </li></ul><ul><li>Serving the media </li></ul>
    26. 26. What computer hardware do you need? <ul><li>A standard web server with the correct software installed </li></ul><ul><li>OR </li></ul><ul><li>A specialised media server </li></ul>
    27. 27. Both have streaming capabilities but why is one better than the other? <ul><li>Live Streaming requires a dedicated media server </li></ul><ul><li>A web server is fine for low usage streaming files but if volume of people wishing to stream from your site is above 10 at a time you need a media server. </li></ul><ul><li>Media Servers give you much more control for your streams and offers many more services for your clients. </li></ul><ul><li>Media Servers enable 2 way communication the client can say rewind your media file (only for unicast). </li></ul>
    28. 28. Web Server V Media Server
    29. 29. Media Servers <ul><li>Servers needed to serve streams. </li></ul><ul><li>In order to stream, a web site must install media servers into it’s network. </li></ul><ul><li>Capacity is typically measured by the maximum number of concurrent streams that the server can serve. </li></ul>
    30. 30. Multiple Stream <ul><li>From a normal web server </li></ul><ul><ul><li>Content has been encoded for one bit rate only </li></ul></ul><ul><ul><li>Not really streaming, just being downloaded </li></ul></ul><ul><ul><li>TCP will resend lost packets and could cause playback pauses </li></ul></ul><ul><li>Dedicated media server </li></ul><ul><ul><li>Content can be encoded at multiple bit rates and the server will choose the right one </li></ul></ul><ul><ul><li>Server uses proprietary protocol to control content – can choose best transport </li></ul></ul><ul><ul><li>Server is tuned to provide optimum performance under heavy use – big beefy machine, multiple CPU’s, high memory and disk drive space. </li></ul></ul>
