9. 40 Combo Mode The Combo Mode gives you access to playback features in addition to Play commands Specifically this mode allows you to play up to 15 different videos or playlists It also allows you to Still Resume Stop or Loop those videos As a matter of fact if you ve worked with any of the predecessors of the DVMHD 8500 you ll realize that this mode is identical to the mode that those products i e DVMHD 7400 DVM2 PK 8001 etc use Playing files in this mode is very similar to the Encoded Play except that you have 4 bits to specify the clip number instead of 8 bits This allows you to play any clip from 1 0001 in binary to 15 1111 in binary The inputs are change sensitive that is when a change is detected the new file will be played It is therefore important that the four bits change at the same time 50ms from each other to be exact If a file is triggered during playback the DVMHD will normally interrupt playback and begin playing the triggered clip The only exception to this rule is when a playlist is currently running and is in an Uninterruptible state In this situation the file input will be completely ignored see the Playlist Control section for more information The 4 remaining inputs provide direct access to Resume Still Stop and Loop the clip This functionality is covered in more detail in the following table which describes how each input behaves in the Combo Mode Input Function Description N

16. below ON refers to the DIP switch being in the DOWN position while OFF means the UP position 1 Sync Input Type C Sync Blackburst 2 16 There are two common types of video sync sources Composite Sync C Sync and Blackburst A typical C Sync signal operates at a peak to peak voltage of 4V However Blackburst sync signals are typically much lower at less than 1V peak to peak This DIP switch settings allows the DVMHD to reliably support both types despite this drastic difference in signal amplitude Switch 1 is used to select between the two sync types By default the DVMHD ships with this switch in the OFF position which configures the sync input for Blackburst If you want to connect a C Sync generator to the DVMHD you ll need to set this switch to the ON position for C Sync operation Blackburst 750 Video Sync Termination When distributing video sync it s standard practice to terminate every dedicated video sync line with 75O An ideal system design would provide a dedicated sync line for each DVMHD from the video sync generator However there are circumstances where you may need to split a single sync line typically done using BNC T connectors so that it can be shared with multiple DVMHD s In this situation having termination enabled on every DVMHD in the chain could easily over terminate the line degrade the signal and result in the DVMHD s being unable to lock to the sync input When video sync i

18. frame synchronization between DVMHD s two requirements must be fulfilled First all DVMHD s must be locked to the same video sync source This is the only way to guarantee that they will display each frame at exactly the same moment It is also the only way to keep the machines from drifting which results from them playing at slightly different speeds The second requirement is that all DVMHD s must be told to play at exactly the right moment and at exactly the same time To be more specific this moment is just after a new video frame is encountered Telling the DVMHD s to play at this precise moment ensures that they all have time to process the Play command and make preparations to begin playback when the next video frame is encountered If the Play command is issued too close to the end of a frame this will likely result in the players starting at slightly different times This is because some players might process the Play command in time for the next video frame while others might still be processing the Play command forcing them to wait until the next frame The result of this is that each video has the potential to be out of sync by 1 video frame For many synchronized applications that is an unacceptable margin of error The following sections contain information on how to meet these requirements and achieve perfect frame synchronization between multiple DVMHD s Sharing Video Sync Between DVMHD s The first st

23. reasons that are beyond the scope of this manual broadcasters typically require all of their video equipment to be slaved to an external sync source Configuring the External Sync In order to lock several DVMHD s together with External Sync you will need a Video Sync Generator If you require advice or product recommendations please contact your Alcorn McBride representative The yellow LED located next to the sync connector only illuminates when a sync signal is detected This indicates that the DVMHD is using that sync signal to generate video 64 Sync Mode The DVMHD is designed to accept either of the two most widely used types of sync Composite sync and Blackburst sync Once you determine what type of sync source you intend to use you must set the Sync Mode DIP Switch to the corresponding type If you are using Composite sync typically referred to as C Sync the Sync Mode DIP switch must be in the ON position Therefore setting the DIP switch to the UP position would configure the DVMHD for Blackburst sync Setting this switch is necessary for the DVMHD to interpret the sync signal reliably 750 Termination It is always good practice to terminate every active sync line with 750 This means that the 750 DIP switch should always be ON whenever the DVMHD is receiving sync directly from a sync generator or video distribution amplifier The only occasion where you would want to disconnect the 7
24. the desired result whatever that may be since the DVMHD is forced to prioritize which file type it should play in that circumstance A playlist file is nothing more than a list of DVMHD commands in a text file These commands which are listed in the Command Protocol section are the same commands that are used by all of the DVMHD s control interfaces Although any of the supported commands can be used playlists usually contain Play commands which cause the DVMHD to play video clips from the Compact Flash card When a playlist is being used the commands are processed in the order in which they appear in the list The playlist is an ASCII text file and be made using any ASCII text editor like notepad or using the Playlist Builder program available from http www alcorn com support software html A playlist can be triggered by Serial or Ethernet commands as well as Inputs on the Input Output Control connector As a matter of fact triggering a playlist is exactly like triggering a video file to play For example let s say you send the DVMHD the following serial command 2PL lt CR gt This command will cause the playlist file PLYOOO02 LST to start playing Using Input Output Control to play file 2 will also start PLYOO002 LST It is a very common requirement in applications for the DVMHD to power up and launch a playlist on its own This can easily be done by naming the playlist file PLY00000 LST This assigns the playl

Your computer will prevent you from copying a file any larger than this to the Compact Flash card If your application requires a longer playback time than a 4GB limitation will allow the best solution is split your file into several segments using a file splitting program One suggestion is a software package called File Splitter which can be downloaded at http www filesplitter org Using this method a large file can be separated into several segments which the DVMHD can treat as a single coherent video file Here s how it works Let s say that you have encoded a 10GB Transport Stream file that you want to play in the DVMHD First you will need to use a utility like File Splitter to divide this file into several chunks smaller than 4GB To be safe you could divide the file into 2GB chunks When the splitting process is complete you should have 5 files Rename those files like this Feature_00001 MPG Feature_00001 001 Feature_00001 002 Feature_00001 003 Feature_00001 004 Keep in mind that 00001 is the first segment Feature 00001 001 is the second segment and so on When you are finished renaming the files copy them to the DVMHD s Compact Flash card At this point all you have to do is treat Feature 00001 MPG as you normally would For example if you send a command to Play File 1 the DVMHD will automatically play through all of the file chunks without you having to do anything special You can
