11. You try to play a file that has an .avi extension or a file that you know is an mpeg2 and neither will play. Why?

12. Codecs and Wrappers A Codec is the method with which a file is encoded DIVX XVID Cinepak Intel Indeo Main Concept

13. A Wrapper Defines the File Type .avi .mpeg .mp4 DIVX and XVID are .avi filetypes Main Concept is an .mpeg filetype This can cause many problems for network usage The user device must have the codec installed Even then, problems can arise if the file was encoded with non-standard bit rates

14. Solution I Use standard codecs and bit rates Uncompressed or DV .avi Mainly used as high quality container for captured video that is to be output for DVD or Film. DIVX Now supported by many hardware manufactures Mpeg1 can be good for downloading – decent quality Mpeg2 for output as DVD Quicktime, Windows Media, Realmedia, Flash FLV for streaming Mp4 for downloading and portable devices

15. Solution II Transcoding for Streaming or playing Running the original video (e.g. XVID) through another encoder (e.g. mpeg1) “live”

16. UPnP Servers and Clients

17. UPnP Universal Plug and Play Developed by Intel as a standard architecture for delivering media (Audio, Photos, Video) Client Server Based

18. Servers & Clients Software Servers Twonkyvision Media Server TVersity Media Server Windows Media Connect Nero Software Clients On2Share Cyberlink
