1280x1080 versus 1920x1080.... what's the difference??

If I export to HDCam tape as a 1280x1080 sequence, would it look any different than if I exported 1920x1080?
When I export to tape at 1280, it fills the entire frame, just like 1920... aspect ratios are correct.. Im baffled.

Is one anamorphic and the other not? Which deck? Any chance it is centering the footage and chopping the sides?
Odd.

Exposure versus Brightness: What's the Difference?

What's the difference in what is controlled by Exposure and Brightness?
(v. 1.4 if it makes a difference)

The easiest explanation is if you know the Photoshop Levels dialog box. The LR Exposure setting is the rightmost of the three sliders that sets the white-point - any tones above it are pure white. The LR Brightness setting is the middle slider that affects the gamma i.e. the curve that boosts/lowers the midtones. Note that adjusting the brightness setting will never force any tones past the white-point and blow them out. The latter is purely controlled by the Exposure/white-point control.

Skype versus facetime. what's the difference?

trying to assess features between iphone 3 versus 4. Facetime sounds like it works inly w iphone 4. But couldn't you use skype on iphone 3 with same results?

Something that is similar to Facetime but works over 3G and Edge is a App call Tango.
I have used to place video calls and it worked ok ( in my case better than Skype),
You do not need the app running in the background to to receive a call, so it will not drain your battery.
if you want, It can work audio only like a normal phone.
Have Video conference (not as good as Facetime but it was better than Skype).
It supports cross platform (phones only)
The only thing is that will not work in a Mac or PC computer, just phones.
You can find it at the App store.

Copy versus Super Copy-what's the difference?

Hello,
Can someone explain what is the difference between "copy" and "super copy" functions in CUCM? What additional parameters will the super copy replicate over what a "copy" will do?
Thanks in advance,
Adil

Hi Adil,
In addition to the good info from my friend Nadeem (+5)
From the CUCM docs;
•To copy an existing phone, locate the appropriate phone as described in "Finding a Phone" section, click the Copy button next to the phone that you want to copy, and continue with Step 5.
•To copy an existing phone and copy the directory numbers, speed dials, busy lamp field/speed dials, and service URLs that are associated with the phone, locate the appropriate phone as described in "Finding a Phone" section, click the Super Copy button next to the phone that you want to copy, and continue with Step 5.
Note The lines that get copied become shared lines between the original phone and the new phone.

X-tended dynamic range versus x-tended dynamic range pro: what's the difference?

What is the difference between X-tended dynamic range, Sony's version of HDR, and X-tended dyanmic range pro?

Hello,
The PCI-4472 would be best suited for vibration measurments. It has 24-bit resolution, Simultaneous Sampling, Hardware Time-to-Frequency Domain Conversion, 110 dB Dynamic Range, and hardware filtering. See the following Link for more details on the 4472: http://sine.ni.com/apps/we/nioc.vp?cid=10572〈=US
The 6289 was not built with vibration analysis in mind, the the dynamic range is not spec'd.
Let me know if you have any further questions.

What is the difference between HUI emulation and MMC?

This may help clear up my issues with dm24 & LE. I am trying to have channels 1-24 of the Tascam dm 24
control volume and pan..etc for tracks 1-24 of LE (AUDIO, Midi and or softsyths, inst), without having to use the mouse to select the LE tracks directly. In other words I need to use the dm24 as a control surface. What is the difference in using mmc to do this versus Control surface. I cannot locate the proper compatible driver or whatever it needs to get this to work in LE.. I even tried using the dm24 macro environment found on tascams site .. all it does is allow me to see the faders move in the environment( bidirectionaly) , but I cannot interact with the actual LE audio, midi and softsyth tracks , unless I actually select the tracks with the mouse, I do not need the dm24 do do this , as this was possible with my KX controller using the volume slider. It appears as if I may have a total lack of understanding of the dm 24 functions regarding using it as a control surface for LE 7.2.3

Like previously stated, refurbished can mean many things. Someone may buy a camera and when they get it have buyers remorse and return it unused, but, once Canon gets it back they have to completely check it out to make sure it meets specs and then they sell it as refurbished. You might get a camera with 0 shutter actuations but you might get one with 1000 or more shutter actuations. Either way Canon completely rechecks each camera before they sell it. I have bought 2 refurbished DSLRs from Canon and they have both been great cameras. You couldn't tell if they had ever been used or not. Recently Canon started offering a 1 year warranty on refurbished DSLRs but I am not sure if that applies to other models or not.

What is the difference between jsp :include and server side include

what is the difference between jsp :include and server side include(request dispatcher include method)????
i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
do suggest if u hav ny other diff in this context...

The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

What is the difference between Aspect Ratios?

Hello. I couldn't find any specific documentation regarding this.
I am working on an iPhoto 09 slideshow project using the scrapbook theme. I am planning to export the slideshow as a movie (it looks like the default export is mpeg 4 but I could also export as a quicktime .mov) and then move to iDVD to burn on a DVD. Ultimately, I need to show it on a projector using a DVD player. I'm not sure what the projector's resolution is but I assume 16:9 will be the best aspect ratio for the highest quality.
In the slideshow settings, there are 4 different aspect ratios:
1) This Screen (16:9)
2) HDTV (16:9)
3) TV (4:3)
4) iPhone (3:2)
What is the difference between This Screen (1) and HDTV (1)? Does it matter? Any other suggestions?
Thanks.

Terence Devlin wrote:
Aspect ratio is the ratio of the width to the height of the image - in other words it's about shape. So both the 'This Screen' and the 'HDTV' settings will be the same Aspect Ratio.
The Aspect Ratio has no bearing on the quality, only the shape of the final images.
TD is absolutely correct here. The aspect ratio is only the shape of the image, not the quality. Basically, you need to decide if you are designing the show for viewing on a HD tv (16:9 or widescreen) or a SD tv (4:3 or squarish). A couple of years ago this choice was easy since most tv's out there were still 4:3, but today, the opposite is true. The popular choice now would be 16:9.
The biggest problem you will have with the quality of your slideshow is the
fact that you're burning it to DVD.
Your slideshow will be heavily compressed to fit the DVD spec of 640 x 480
pixels and this can lead to soft images or even blurry ones.
I think we're getting "compression" and "resolution" confused here a bit, or at the very least, we're using the wrong terminology.
For everyone's benefit, let me try to explain...
If you show an image that is native 640x480 on a screen that is native 640x480 (standard def tv screen), the image will look just fine. This is resolution and will not effect quality as long as you don't try to view at a higher resolution than the image actually is.
(If you try to view a 640x480 slide show in full screen mode on your computer monitor which is running at 1280x1024, the image will look horrible.)
Trying to view a higher rez image (ie: 3200x2400) on a lower resolution (ie 640x480 or SD tv) screen will reap NO benefit in quality. Remember that a SD TV will only show 640x480 (or 720x480) and no higher, so there is no benefit in trying to cram more pixels into an image than the screen can actually show.
Of course this all changes if you're going to view it on today's HiDef tvs, but even on them, the resolution tops at at 1920x1080. Once again, using a very high def image (ie: 3840x2160) will reap NO benefit since the resolution of the screen it's being viewed on tops out at 1920x1080. The aspect ratio on this type of tv is now 16:9 so the images shape will be wider than a normal tv (4:3).
Compression is the scheme used to compress an image to reduce it's file size, thus reducing it's quality. JPEG is a common form of image compression, and the amount of compression can be adjusted..the more compression, the more degradation of quality. This has nothing to do with resolution.
Depending on how you're going to process (iPhoto, iMovie, iDVD), the program will reduce the resolution of the original image to the resolution of you output. In other words, don't worry about doing any kind of resolution change prior to creating the dvd, as the program you choose to use will simply lower the resolution (this is not compression) to fit the output you choose.

What's the difference between jsp and jsf?

who can tell me what's the difference between jsp and jsf?
I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

Hi,
Find the difference between JSP and JSF
1. A developer has more control with JSP, but (should) get easier development with JSF
2. Event handling is done differently in JSP (HTTP) and JSF (Java)
3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
4. The end product should also be defined differently - JSP page versus a JSF application.
Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
If you are in this vacuum here are some key points promoting JSF:
1. Fundamental unit is the Component
2. Built in event and state management
3. Component sets can be provided by any vendor
4. Closer to ASP.Net or Swing development
5. Choice of UI technology
6. Scale up (rich clients)
7. Scale down (mobile devices)
8. Built into J2EE containers in J2EE 5.0 (tentative)

What's the Difference Between OLAP and OLTP?

HI,
What's the difference between OLAP and OLTP ? and which one is Best?
-Arun.M.D

Hi,
The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
Building the Data Warehouse, 2nd Edition by W. H. Inmon
With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

What is the difference between J2EE Engine vs WAS in SAP

Hello All,
What are the differences between J2EE engine included with BW 3.0B and the WAS 6.20 ? what are the limitations of J2EE engine in terms of functionality.
Thanks in advance
Ravi

Hello Nitzan,
Thanks for the response. Just to clarify my question, There is a J2EE engine as part of BW 3.0B. What is the difference in terms of functionality of J2EE engine which comes bundled with BW 3.0B versus say WAS 6.20.
1. The J2EE engine which comes bundled with BW 3.0B, is it a run time or a full product where a java app can be developed and deployed to integrate with BW or do you need WAS for that purpose.
Thanks & regards

What is the difference between DSo and Infocube

Hello,
Kindly tell me what is the difference between DSO and Infocube?
And please tell me how to take the desicion that in whichi case we can use DSO and in which case we can use Infocube..

Hi ,
DataStore object serves as a storage location for consolidated and cleansed transaction data or master data on a document (atomic) level.
This data can be evaluated using a BEx query.
A DataStore object contains key fields (for example, document number/item) and data fields that can also contain character fields (for example, order status, customer) as key figures. The data from a DataStore object can be updated with a delta update into InfoCubes and/or other DataStore objects or master data tables (attributes or texts) in the same system or across different systems.
Unlike multidimensional data storage using InfoCubes, the data in DataStore objects is stored in transparent, flat database tables. The system does not create fact tables or dimension tables.
Use
The cumulative update of key figures is supported for DataStore objects, just as it is with InfoCubes, but with DataStore objects it is also possible to overwrite data fields. This is particularly important with document-related structures. If documents are changed in the source system, these changes include both numeric fields, such as the order quantity, and non-numeric fields, such as the ship-to party, status and delivery date. To reproduce these changes in the DataStore objects in the BI system, you have to overwrite the relevant fields in the DataStore objects and set them to the current value. Furthermore, you can use an overwrite and the existing change log to render a source delta enabled. This means that the delta that is further updated to the InfoCubes, for example, is calculated from two successive after-images.
An InfoCube describes (from an analysis point of view) a self-contained dataset, for example, for a business-orientated area. You analyze this dataset in a BEx query.
An InfoCube is a set of relational tables arranged according to the star schema: A large fact table in the middle surrounded by several dimension tables.
Use
InfoCubes are filled with data from one or more InfoSources or other InfoProviders. They are available as InfoProviders for analysis and reporting purposes.
Structure
The data is stored physically in an InfoCube. It consists of a number of InfoObjects that are filled with data from staging. It has the structure of a star schema.
The real-time characteristic can be assigned to an InfoCube. Real-time InfoCubes are used differently to standard InfoCubes.
