How to decode audio data from dvi/rtp to PCM linear

Hi all,
I am getting audio data as DVI/RTP 4 bit mono as input stream but not able to create player for this can any one send me any decoding function so that i can change this data to PCM linear 16 bit format

S+S, ahh an academic.
This is actually a forest-trees issue here.
What your doing is appending the files, which would result in a size of 2S. What you want is somthing of size S. To do this you would need a Normilized merge. I say normalized merge because thats going to give you the best result while still avoiding out of range values.
This is easy enough to by hand if both streams S1 and S2 are of the same frequency. If they are not the same frequency, the result will be size of the larger file when convereted to whatever uniformfrequency.

How to mix audio data from multiple streams without increasing in size?

For example, two clients use JMF to capture audio in linear format (content type is raw)and both send the captured data to a third client where it performs mixing to generate one data stream. Suppose each source data size is S, the mixed stream (using JMF "merge") size is S+S which is not what I want. Is there any function to generte mixed stream with size S? I don't need to the capability to reverse mixed stream back to two individual source streams.
Thanks.

Decoder from DVI/RTP 4 bit mono to PCM linear 16 bit

I guess, one topic is more than enough... http://forum.java.sun.com/thread.jspa?threadID=5213182&tstart=0
Just get the specs of the data format and do the decoding yourself.

Acquire/manipulate audio data from internet stream

I want to acquire the audio data from an audio stream (i.e. pandora, youtube, etc.) from the internet. If I can get this data and be able to play it/graph it/etc in Labview, I will be pleased. However, I'm not sure if this is even possible not knowing the details behind how packets are built and transmitted over the internet.
The closest I've come is using the acquire_sound.vi and taking the data from the sound card; albeit, it's very noisy.
For fun though, I'd like to do something directly from the audio stream itself (perhaps building a dll?) to gain a better understanding and experience.
Any advice is greatly appreciated!

Dnor -
As far as I am aware there is a specific data time for audio streaming online, and it's something specific you would likely need to know on a low level to communicate/copy to. Although it wouldn't be real-time, you can run a Windows audio recording program like TotalRecorder which should save and convert the audio output to .wav. Then run a LabVIEW vi to read the wave file, which you could graph. There is a KnowledgeBase on setting up the read from .wav file here if you'd like to go that route: http://digital.ni.com/public.nsf/allkb/1BE60DBBFA22ACC186256DFB000B8464.

How can I Move data from one column to another in my access table?

I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
I understand how to drop a column or add a column, how do I transfer data from one column to another.
Here is my trial code:
<cfquery name="qQueryChangeColumnName" datasource="#dsn#">
ALTER TABLE leaderboard
UPDATE leaderboard SET points2 = points3
</cfquery>
Unfortunately, I get the following error:
Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
How can I transfer my data with the alter table method?

I looked up the Access SQL reference (which is probably a
good place to start when having issues with Access SQL), and
it suggests you probably need a WHERE clause in there.
I agree the documentation is a good place to start. But you should not need a WHERE clause here.
Too few parameters. Expected 1.
If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..

How do i transfer data from one internal tabe to another.

Hi All,
         How do i transfer data from one internal tabe to another.
         Can i do it ebven if he tables are different in structure.
Please Advice.
Thanks in advance.

Hi Saket Tiwari,
I hope the earlier post by kashyap is good enough an answer. anywas in addition to it let me give a detailed
explanation of how you can populate an internal table.
1) Append data line by line.
     Syntax : APPEND [<wa> TO / INITIAL LINE TO] <itab>.
this appends new line to internal table <itab>.
2) Using COLLECT statement.
             COLLECT is another form of statement used for populating the internal tables. Generally COLLECT is used while inserting lines into an internal table with unique standard key. The syntax for COLLECT statement is as shown
     Syntax : COLLECT [<wa> INTO] <itab>.
3) Using INSERT statement
     Syntax INSERT [<wa> INTO / INITIAL LINE INTO] <itab> [index <idx>].
INSERT statement adds a line/work area to the internal table. You can specify the position at which the new line is to be added by using the INDEX clause with the INSERT statement.
Now coming to your request..
To append part or all of an internal table
     Syntax
              APPEND LINES OF <itab1> [FROM <n1>] [TO <n2>] TO <itab2>.
*     Note:
Without the FROM and TO options, this statement appends the entire table <itab1> to <itab2>.*
b) To insert part or all of an internal table into another internal table
     Syntax
          INSERT LINES OF <itab1> [FROM <n1>] [TO <n2>]
          INTO <itab2> [INDEX <idx>].
c) Using Move statement.
To copy entire contents of one table into another in one execution
     Syntax MOVE <itab1> To <itab2>.
               OR
          <itab1> = <itab2>.
but u hav to be careful because he contents of itab2 will eb overwritten on the execution of this statement.
These copy the contents of ITAB1 to ITAB2. Incase of internal tables with header line we have to use [] inorder to distinguish from work area. So, to copy contents of internal tables with header line the syntax becomes,
ITAB1[] = ITAB2[].
Coming to the letter part of your question, Yes, we can copy values between tables having different structures.
for this we use
                            MOVE-CORRESPONDING <itab1> TO <itab2>
    this executes the statement for their header lines. Searches for the sub-fields which occur both in itab1 and itab2 and then generates, for all relevant field pairs which correspond to the
        sub-fields ni , statements of the form MOVE itab1-ni TO itab2-ni. The other fields remain unchanged.
I hope the information provided has been of your help.
Reward if useful.

Jose

How to pass the data from a input table to RFC data service?

Hi,
I am doing a prototype with VC, I'm wondering how VC pass the data from a table view to a backend data service? For example, I have one RFC in the backend system with a tabel type importing parameter, now I want to pass all the data from an input table view to the RFC, I guess it's possible but I don't know how to do it.
I try to create some events between the input table and data service, but seems there is no a system event can export the whole table to the backend data service.
Thanks for your answer.

Thanks for your answer, I tried the solution 2, I create "Submit" button, and ser the mapping scope to be "All data rows", it only works when I select at least one row, otherwise the data would not be passed.
Another question is I have serveral imported table parameter, for each table I have one "submit" event, I want these tables to be submitted at the same time, but if I click the submit button in one table toolbar, I can only submit the table data which has a submit button clicked, for other tables, the data is not passed, how can I achieve it?
Thanks.

Hi Rammohan,
You cannot use OPEN DATASET to transfer data from application server to presentation server.
You can do the following :
<b>Do 1st point in BACKGROUND</b>
1. Read the data file from application server into an internal table using OPEN DATASET
<b>Do 2nd point in Foreground</b>
2. Once you get the data into an internal table, then use FM GUI_DOWNLOAD to download it on presentation server
You cannot use the above 2 point together in Background because its not possible. Hence you need program it partially in background and partially in foreground.
Best regards,
Prashant
