1. 1 Net-HD  Future  LIVE HD TV over the web, HD movies online streaming  NGN technologies  What do we have at present?  YouTube - Videos in HD quality  Few another sites with more or less same technology  No streaming online  Problems?  Internet bandwidth doesn’t suit the needs  720p HD live video stream needs ~2.5Mbit/sec  Average connection speed is about ~2.0Mbit/sec  Time - we don’t want to waste it in eternal waiting  Online movies in HD quality?

2. Net-HD  Global Goal of the project  HD Streaming over the web w/o changing bandwidth  Secondary Goals  Development of prototype of software for experimental purposes  Server/Client based application  Manager application for multiple Clients  Half-Real Time VOD streaming experiments

3. Basic structure of application: Net-HD Manager Client/s creates Server request 1. Manager starts 2. Manager creates instances of Clients 3. Clients send a movie requests with specified parameters 4. Server finds requested references 5. Server returns demanded movie stream Global Networking communication

4. Net-HD Tutorial:  Introduction  To run this project requires NetBeans and VS IDE’s  It also requires a dom4j.jar as external library  Basic entities are:  Client – Java implemented  Server – C# implemented  Client Manager – Java implemented  This presentation explains uses and implementation of Client and Client Manager  This presentation uses screenshots of NetBeans IDE

5. Tutorial:  Client  Main form Net-HD  URL – link to movie  Control options  Log for Data Transfer Observation  Hides this form (means it is still working when hidden)  frame from which movie will be played(represents time)  Edit option for this instance of client  Address of server  Port of the server for client to connect

6. Net-HD Tutorial:  Manager  Main Form  General Form  URL – link to movie checkbox  Random URL option from created earlier list – checkbox  Select randomly specified number of Clients  Choose a command from the drop list for all of the selected Clients  Execute chosen command for selected Clients  Load and run XML file with scenario  Opens Form of selected Client  Log Textbox and Show/Clear options for current session log

7. Net-HD Tutorial:  Manager  Main Form  Editing server settings  Set server IP address  Set port through which Clients connect to server

8. Net-HD Tutorial:  Manager  Main Form  Editing server settings  Open a list of URL’s from text file  Save existing URL list to text file

9. 2) Enter number of Clients 3) Choose one of the options : b)Delete existing Client & add new one 4) To view list of created Clients : Press drop list 1) Press EDIT then NetHD CLIENT a)Add new Client Net-HD Tutorial:  Manager  Main Form  Creation of multiple Clients

10. 1)Press “Edit” then “URLs list” 2)In next form add a link of URL 3)In the “logs” window possible to use that the URL added successfully 4)To see the added URLs press dropped list. Net-HD Tutorial:  Manager  Main Form  Editing URL list

11.  Cengine – class that contains all logical functions  Cgui – class that responsible for graphical interface  Cmain – Start point for GUI  Cnetwork – class that is responsible for networking components  Cscreen – represents log box with data shown during transmission  Cvideo – class that responsible converting data to video file  RandomGUID – class that generates a unique ID for Client instance  SetingsGUI – Graphical form for setting “Host” and “Port” Net-HD Packages explanation - basics  Client

12. Net-HD Packages explanation - basics  Log  Main  LogHD– data structure that remembers all events with application  MainFrame – basic start point for the project, brings up a screen

13.  EditNetHDClientsWindow – Graphic window that responsible of creating new Client  EditURLslistWindow – Graphic windows for adding URLs links  FileManager – Graphic window for file chooser  Mengine - class that contains all logical functions of manager  Mgui – Graphic window of manager  Mmain - Start point for GUI  NetHDServerSetingsWindow - Graphical form for setting “Host” and “Port” of server. Net-HD Packages explanation - basics  Manager

14. Net-HD Code explanation - basics  Client  Main functions Play pressed : Cgui.Class called  Methods invoked in order of appearance 1.Cengine.setFrame(frame)  Sets current Client offset frame from which movie will starts 2.Cengine.Play(URL)  Cnetwork.connect() - Connects to server  Cnetwork.setMessage(msg) – Prepares a message for a server  Cnetwork.GetVideoStream() - Gets video from server for this instance of Client

15. Net-HD Code explanation - basics  Client  Main functions Pause pressed : Cgui.Class called  Methods invoked in order of appearance 1.Cengine.pauseSave()  Sets flag request to status REPEATED  Cengine.pauseTime() – saves time when movie stopped  Cengine.getLastPackage() – saves last package to restore point

16. Net-HD Code explanation - basics  Client  Main functions Stop pressed : Cgui.Class called  Methods invoked in order of appearance 1.Cengine.Stop()  If Client was receiving data then  Cnetwork.sendMessage(stop) – message with “stop” sent to server  Cnetwork.disconnect() – kills connection with the server

17. Net-HD Code explanation - basics  Manager  Main functions Scenario Execute pressed : Mgui.Class called  Methods invoked in order of appearance 1.Mengine.scenarioExecute()  Function trys to read from XML file  If successfully then program executes scenario

18. Net-HD  Manager Main function : This Manager created for manage Clients. Execute button pressed : _engine.setURL(); - take urls links Checking one of two options : 1)_engine.selectFirstsClients(Take “All” clients); or 2) _engine.selectFirstsClients(Take num of client); LogHD.addLog(); - add information to “Information vector - LogHD”. this.setLog(); – print all changes on screen log.

19. Net-HD  Manager Main function : This Manager created for manage Clients. _engine.executeSelected(take info from Comand ComboBox) {  this function have Switch for 3 options : PLAY, STOP,PAUSE.  checking on of two options : Random or No  Creat new Client ;  client.SetNetHDserver(_host, _port); - set host & port data for client whos took from Server Settings  client.start(); - start new Thread/ Client with all describe data. }
