how can i request the actual time code of digital video recorder, i am using RS232 interface for asking actual time code of digital video recording

If you have an RS-232 interface to the digital video recorder, it may be that you can send a command to the video recorder in order to get the time code sent back to your application - you would then read this as a string and then incorporate this data into your program.
The best source of help will be any documentation you have relating to the serial (RS-232) interface with the digital video recorder. This documentation should have commands that you can send to the recorder and expected response strings that you should get back from the device. This task should be straightforward but can often be frustrating without documentation about the video recorder. This will not be something that you can "guess" - past experience in writing serial communication ap
plications has shown that a good manual is your best friend.
Failing this if you have any source code for example programs that have already been written to communicate with the recorder, you might be able to extract the relevant ASCII strings and use them within your application. This is true whether you are using LabVIEW or a text-based language.

  • "How can i control the instrument with SCPI command by Borland C++ v3.1 using RS232 port"

    "hi....
    I've ever controlled some instrument by GPIB interface using Labview 6.0...it's really easy to implement .....but the problem is that i hvae to control those instrument under the pure DOS environment now ..so i have to abandon the using of GPIB interface and Labview ....then i choose the RS232 interface with programing the Borland C++ v3.1 and sending the SCPI command by bioscom()....but it got no response at all......so i am wonder if i can control those instrument by using RS232 interface and Borland C++ v3.1 to implement a pure Dos program????if yse,how can i do and is there any sample can be refer to ????
    thank you for you help"

    Hello Alvin-
    We do not have any sample code for programming RS 232 in C on our website. However, you may want to looks at these links for general troubleshooting tips for serial:

  • How can I get the XSLT source code?

    How can I get the XSLT source code?

    Actually, I want to parse customer reviews for academic purpose.
    I'm trying to follow the links in the customer reviews zone.
    For example:
    In the following page
    http://www.amazon.com/gp/product/customer-reviews/B000LU8A7E/sr=1-1/qid=1180473311/ref=cm_cr_dp_all_helpful/102-2890495-8864146?ie=UTF8&n=1065836&qid=1180473311&sr=1-1#customerReviews
    in the "customer reviews" section, there is a link "next" that gets the next 10 reviews.
    The thing is that I don't know how to imitate its action using java and actually, I'm not sure if it is possible to do that using software.
    I tried to look at the source code that I got using the previous java code I posted and I see that the next link always has the following href attributes "http://www.amazon.com/gp/product/customer-reviews/B000LU8A7E"
    I tried to see if there is any javascript that tells the page which 10 reviews to get but with no success.
    So if anyone knows how to imitate the next link action using software that will sure help me a lot.
    Thanks in advance

  • How can I get the elapse time for execution of a Query for a session

    Hi ,
    How can I get the elapse time for execution of a Query for a session?
    Example - I have a report based on the procedure ,when the user execute that it takes say 3 min. to return rows.
    Is there any possible way to capture this session info. for this particular execution of query along with it's execution elapse time?
    Thanks in advance.

    Hi
    You can use the dbms_utility.get_time tool (gives binary_integer type value).
    1/ Initialize you time and date of beginning :
    v_beginTime := dbms_utility.get_time ;
    2/ Run you procedure...
    3/ Get end-time with :
    v_endTime := dbms_utility.get_time ;
    4/ Thus, calculate elapsed time by difference :
    v_elapsTime := v_endTime - v_beginTime ;
    This will give you time elapsed in of 100th of seconds...
    Then you can format you result to give correct print time.
    Hope it will help you.

  • On imac 10.6.8 using current version of Aperture.  How can I access the Aperture Library  on my external hard drive that I use with time machine for backup?  I can only access the application but not the library..

    On imac 10.6.8 using current version of Aperture.  How can I access the Aperture Library  on my external hard drive that I use with time machine for backup?  I can only access the application but not the library..

    Go into Time Machine (the program not the bundle on the extrnal disk) and using Time Machine's browser go to the Folder where the library lives. You could look in the library bundle in Time Machine but that won't really tell you much,
    If you want to make sure it truely has backed up your library you will need to restore it and open the restored library with Aperture.
    If all this still has you confused you need to read up on Time Machine in order to get a feel for how it works, for what it is doing and for how to restore files from it.

  • How can i find the value category code in CJVC

    Hi Gurus
    how can i find the value category code in CJVC and which tables its stored.can any one tell me.please please

    Read TPIK3 in an internal table, then search COEP-KSTAR in this table, with KSTAR between TPIK3-KSTRF and TPIK3-KSTRT, and other keys like Controlling Area and application/component (eg "PS" in project-system as in CJVC or "PM" in Maintenance as in IW33, multiple application use this table). You can also use a FM like PS_FIND_ACPOS_FOR_KSTAR.

  • How can I calculate the total time in java?

    Hello!
    I need to calculate the total time!
    For example I have start time:
              Format formatter1;
              Date date1 = new Date();
              formatter1 = new SimpleDateFormat("hh:mm:ss");
              String startTime = formatter1.format(date1);
              //startTime = "14:20:40";
    And I have finish time:
              Format formatter2;
              Date date2 = new Date();
              formatter2 = new SimpleDateFormat("hh:mm:ss");
              String finishTime = formatter2.format(date2);
              //finishTime = "08:30:55";
    So, after manually calculating, I get total time: "18:10:15"
    How can I calculate the total time in java? (Using formatter1 and formatter2 I suppose)
    What I need is to print "total 18:10:15"
    Thanks!

    I did the following but, I think something is wrong here:
    I defined before: Date date1 = new Date(); Date date2 = new Date();
    And it should be exactly 5 seconds between them.
    I found delta between date1 and date2:
    Format formatter = new SimpleDateFormat("HH:mm:ss");
              long timeInMilliFromStart = date1.getTime() - date2.getTime() ;
              Date date3 = new Date(timeInMilliFromStart);
              String timeInSecFromStart = formatter.format(date3);
    and I get always
    //timeInSecFromStart = 02:00:05
    But it should be exactly 00:00:05.
    What can be a problem?Because, like I said, a Date measure an instant in time, not a duration. So when you have 5000 ms, and you turn that into a Date, that means 5 sec. after the epoch, which works out to 1/1/1970 00:00:05.000 GMT.
    As I mentioned, if you're not currently in GMT, then you have to set the TZ of the DateFormat to GMT. Right now, it's showing you the time in your TZ. If you included the date in your SimpleDateFormat, you'd see either 1/1/1970 or 12/31/1969, depending on which TZ you're in.
    Bottom line: You're trying to use these classes in a way they're not meant for, and while you can get the results you want for a limited set of inputs if you understand what these classes do and how to work with that, it's a brittle approach and comes with all kinds of caveats.
