  • Digital HD Transition

    - by Bill Evjen
    The HD Experience Roughly 53% of the viewing public has HD capable devices in their home 24% think they are watching HD while they have no subscription to any HD content Today’s HD Considerations Choices abound: format resolution – 720p, 1080i/p frame rates compression and wrapping audio compression and delivery metadata packaging, delivery, and usage content delivery protocols Metadata is going to be a part of the overall experience With emerging technologies: Super Hi-Vision (SHV, UHDTV 4320p), 3D HEVC/H.265, WEBM/VP8 HDBaseT, P2PTV Dolby Pulse/HE-AAC Industry standardization Metadata registration, packaging, and delivery standards Improved picture and sound quality is a logical next step but we need to also think about the end to end viewing experience including; 3D video and audio content Mixed-mode viewing to bring interactive and immersive experiences Content Transportability both on-to and off-of the aircraft High Definition Standardization Analog switch off around the world DTV transition completed: 17 countries DTV transition in progress: 45 countries The EU has mandated the end of 2012 as the final date for Analog Switch Off D-Cinema was standardized by SMPTE in 2006 Airlines are installing HD displays today Passengers are bringing their own devices now HD TV on airlines are getting bigger and bigger – bigger than SD was – now up to 23” Gray scale data input for color – 6 to 8 bit Contrast – 400 to 700 Backlit – LED Encryption – can it be the same for HD?

  • QML: Overriding a signal handler from other element

    - by user3490458
    Is it possible to override an elements action (eg onTriggered() of a Timer) from within the onClick() of a button? Something like so- Button { id: centerBtn objectName: "button" onClicked: { delaytimer.running = true; delayTimer.onTriggered {}; // override here } Timer { id: delaytimer interval: 1000 running: false repeat: false onTriggered: //something implemented here } }

  • HDMI signal interrputs after 10 minutes plugged in a TV

    - by desert_unbound
    Ubuntu 11.10, Dell Inspiron N4050, VLC, Jupiter I'm trying to watch movies through HDMI output on a TV, with VLC, with the notebook unplugged from AC (but with enough battery for 2-3 hours of use), just with TV display (the notebook display stays off) And from 10 to 10 minutes, the TV turns black, and according to the TV, the HDMI cable is unplugged. But using the touchpad makes the screen appear again. In "screen" options, on system settings, i've set the screen to never turn off, and never reduce brightness using battery. In "power" settings, i've set to not suspend when using battery. In Jupiter, i've set (while trying to watch the movie) to work in maximum performance. I'm pretty sure it's not VLC, because i've set it to override power options and screensaver options (and also im not using xscreensaver). Also the movie continues, when the screen is black Maybe there's something that i'm missing? When i plug the HDMI in the notebook, i use jupiter to change the display (using the option "external display only")... maybe is that ?

  • Western Digital HDD now freezes my BIOS when loading the video card!

    - by Vercas
    After I have successively and successfully installed 3 Windows XP's on the same partition (Don't ask why...), I restarted my computer again and the BIOS just froze when it loaded the video card. Together with my uncle, we tracked down the problem and found out it's the HDD's fault. We tried booting without the HDD and it worked! (No other HDD (I have only one) but with a Ubuntu Live CD in.) We tried the HDD with a different data bus (It was from an identical computer) but that one didn't let my BIOS recognize the HDD. We also put the HDD in another computer as the second HDD and it DID recognize it but Windows XP kept saying it cannot install a driver and that it installed successfully. Happily, I have managed to backup some of my most important files in that other computer. The following is a list of tests that we have run. With the HDD Original data bus Original computer Result: BIOS freezes WITHOUT the HDD Original data bus Original computer Result: Everything works just fine! With the HDD ANOTHER data bus Original computer Result: Cannot see the HDD With the HDD Original data bus ANOTHER computer Result: It worked! With the HDD ANOTHER data bus ANOTHER computer Result: It worked! During the tests, we had only two data buses and two computers. (each data bus from it's own computer) Strange thing is that the second data bus cannot let the BIOS see the HDD in my computer but works just fine with the other computer. I beg you to help me! I have my most important data on that HDD and I really cannot afford to buy another decent IDE HDD now!

  • Best way to make a safe deal when delivering websites and other digital material [closed]

    - by AntonNiklasson
    I have a small business where I create websites. Lately I have been trying to evaluate the way I handle everything besides writing code and picking nice colors etc. I am trying to come up with a decent contract which keeps me safe and makes sure I get paid and so on. I would like to hear from more experienced people how they handle clients. How do you agree on what is supposed to be delivered? Is it a good idea to make sure you get paid say 30% before doing any work at all? Any other helpful tips or routines you can think of are of course gratefully appreciated.

  • Is segfault signal always sent to application

    - by noonex
    My application usually crashes and prints stack to log if received segfault signal. But in some environment the 'dmesg' shows segfault messages related to my application, but application uptime is much older. Can segfault be suppressed and application doesn't receive signal? Or what errors from dmesg can mean ?

  • White Paper on Parallel Processing

    - by Andrew Kelly
      I just ran across what I think is a newly published white paper on parallel  processing in SQL Server 2008 R2. The date is October 2010 but this is the first time I have seen it so I am not 100% sure how new it really is. Maybe you have seen it already but if not I recommend taking a look. So far I haven’t had time to read it extensively but from a cursory look it appears to be quite informative and this is one of the areas least understood by a lot of dba’s. It was authored by Don Pinto...(read more)

  • Benchmarking CPU processing power

    - by Federico Zancan
    Provided that many tools for computers benchmarking are available already, I'd like to write my own, starting with processing power measurement. I'd like to write it in C under Linux, but other language alternatives are welcome. I thought starting from floating point operations per second, but it is just a hint. I also thought it'd be correct to keep track of CPU number of cores, RAM amount and the like, to more consistently associate results with CPU architecture. How would you proceed to the task of measuring CPU computing power? And on top of that: I would worry about a properly minimum workload induced by concurrently running services; is it correct to run benchmarking as a standalone (and possibly avulsed from the OS environment) process?

  • Persisting natural language processing parsed data

    - by tjb1982
    I've recently started experimenting with natural language processing (NLP) using Stanford's CoreNLP, and I'm wondering what are some of the standard ways to store NLP parsed data for something like a text mining application? One way I thought might be interesting is to store the children as an adjacency list and make good use of recursive queries (Postgres supports this and I've found it works really well). But I assume there are probably many standard ways to do this depending on what kind of analysis is being done that have been adopted by people working in the field over the years. So what are the standard persistence strategies for NLP parsed data and how are they used?

  • Silverlight 3.0 and ADO.NET data service framework(An error occurred while processing this request)

    - by ybbest
    Today , I try to write a Silverlight app that talks to SharePoint 2010 using the REST API.However after deploy the silverlight app and run the code , I got the following error.In order to fix this I need to make the target framework of your caller application to 4.0,in this case I need to use Silverlight 4.0 instead 3.0.After I have done that and redeploy the solution to the SharePoint.It works like a charm.   Exceptions details: System.Data.Services.Client.DataServiceQueryException: An error occurred while processing this request. Request version ’1.0′ is too low for the response. The lowest supported version is ’2.0′. However , if you got the error like this: Could not load type ‘System.Data.Services.Providers.IDataServiceUpdateProvider’ from assembly ‘System.Data.Services, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′,then you need to install ADO.NET Data Services Update for .NET Framework 3.5 SP1 ,you can download here (for windowns 7 and server 2008 r2 ) or here (for windows vista of server 2008).

  • Ideas to automate customer order processing? [on hold]

    - by user2753657
    i am looking for a way to automate the order processing in my webshop. Normally, a user buys a product in my webshop, then, i receive an order confirmation email with order details, address etc. After receiving the order email, I login to my suppliers website and input the order details manually. My supplier then ships the item to the address specified by me. I am looking for ideas how to automate this process, especially in the case if i receive for example 4-5 order emails at one time (and not one by one with several hours between)... I was looking at the program Winautomation, but i am not sure if this fits my needs. Any ideas are appreciated. thanks!

  • Initiating processing in a RESTful manner

    - by tom
    Let's say you have a resource that you can do normal PUT/POST/GET operations on. It represents a BLOB of data and the methods retrieve representations of the data, be they metadata about the BLOB or the BLOB itself. The resource is something that can be processed by the server on request. In this instance a file that can be parsed multiple times. How do I initiate that processing? It's a bit RPC like. Is there best practice around this? (First time on programmers. This is the right place for this sort of question, right?)

  • Scaling a video processing application on EC2?

    - by Stpn
    I am approaching the need to scale a video-processign application that runs on EC2. So far the setup is one machine: Backbonejs frontend Rails 3.2 Postgresql Resque + S3 for storage The flow of the app is as follows: 1) Request from frontend. Upload a video. 2) Storing video 3) Quering external APIs. 4) Processing / encoding videos. 5) Post to frontend. I can separate the backend and frontend without any problems, but when it comes to distributing the backend between several servers I am a bit puzzled. I can probably come up with a temporary solution (like just duplicating apps making several instances), but since I don't really have expertise in backend system administration, there can be some fundamental mistakes.. Also I would rather have something that is scalable. I wonder if anyone can give some feedback on the following plan: A) Frontend machine. Just frontend, talks to backend via REST Api of sorts. B) Backend server (BS), main database. Gets request from 1), posts to 2) saves uploads to 3) C) S3 storage. D) Server for quering APIs. Basically just a Resque workers, that post info back to 2) E) Server for video encoding. Processes videos uploaded on 3) and uploads them back. So I will have: A)frontend \ \ B)MAIN_APP/DB ----- C)S3 Storage (Files) / \ / / \ / D)ExternalAPI_queries E)Video_Processing (redundant DB) (redundant DB) All this will supposedly talk to each other via HTTP requests. My reason for this is that Video Processing part is really the most resource-intensive and I would just run barebones application that accepts requests and starts processing them. Questions: 1) In this setup I will have the main database at B) and all other servers will communicate with it via HTTP requests (and store duplicates of databases also I guess..for safety reasons). Is it the right approach or should I have 1 database that everyone connects to (how then?) 2) Is it a good idea to separate API queries from Video Processing part? Logically they are very close (processing is determined by the result of API queries), but resource-wise Video Processing is waaay more intensive. 3) what should I use to distribute calls between backend apps based on load?

  • Broken Creative DTT3500 Digital

    - by djechelon
    Hello, many years ago I bought a Creative DTT3500 Digital surround speakers system. It's been a while since my home theatre started behaving strange. During the past 6 months, I have noticed that the amplifier needed some time before correctly playing digital audio. Until a couple of weeks ago, it needed up to 5 minutes of very noisy "warm up" before playing an "almost" clear audio. Today, I found that even using the analog input (completely disabling digital inputs) the noise persists. Powering off and on the speakers doesn't work. Now, it's reasonable that after almost 10 years, the amplifier got broken. My problem is that I can't simply replace the speakers with another kit from another brand, since 2 speakers in my room are placed in the back wall, with coaxial cables going under the floor but not completely inside a single tube. I mean, I have coaxial extension cables starting from the DTT3500 amplifier, going into the wall, then under the floor in a plastic cable tube, then exiting the tube (still under the floor), connecting to the male coaxial connector of the original cable supplied by Creative, and continuing up to the point close to my bed where the speakers are. I could replace the speakers **only as soon as the new speakers have the same coaxial to bi-polar cables that Creative ships with DTT3500 Another option might be "repairing the amplifier", but I don't know if it's feasible, what should I or a technician look for in the amplifier, and how much would it cost (is it worth to repair or buy a new kit considering the problem above? What do you suggest me to do, basing on the above observation? Thank you.

  • No video signal at boot with custom built computer

    - by Bart Pelle
    After booting my custom built computer, neither the VGA nor the HDMI methods from the video card seem to emit any signal to the display. I have tested both a regular VGA screen and a modern HDMI screen. Both did not receive signal. Below are the specifications from my computer build: Intel Core i5 3350P ASRock B75 Pro 3-M Seagate Barracuda 7200.14 ST1000 DM003 1000GB Corsair Vengeance LP CML 8GX 3M2 A1600 CGB Blue (2 cards) Cooler Master B Series B600 Club 3D Radeon HD7870 XT Jokercard Samsung SH-224 BB Black Sharkoon T28 Case The motherboard does not emit any beeps on startup. The CD tray opens properly and all fans spin. All cables are properly connected. All components are new and no damage was found on any of the components. The fans on the GPU spin aswell. The VGA test we did was by using the onboard graphics from the Intel i5, but this gave no result. The HDMI test was from the GPU which did not emit any signal either. We have not been able to test out the DVI, could this be important to test, even though all the other methods did not work? Thank you for your time and hopefully reply.

  • Two monitors with Mac Mini - one displays black despite receiving a signal

    - by alex
    My Mac Mini outputs to my two new monitors - Dell U2311Hs. The LED on the bezel displays blue when receiving a signal, or yellow otherwise. Both screens are displaying blue. It also seems my Mini can see both of them... However, one of them is black. It just displays black, but appears to be receiving a signal (when I turn the Mac off, it then displays No Signal). To make things weirder, on startup, the boot up (white with Apple logo) appears on the right monitor (the one that now displays black). Occasionally, it flickers up on the black screen for 1 second. I have tried Detect Displays. It appears to do nothing. I'm also running a dual monitor KVM. Video connections are DVI-D. How can I fix this situation? Thanks. Update This is the weirdest thing - I used the DVI-D cable that came with the KVM and it seems to have fixed it - I didn't both because it looks identical to any other DVI cable (in form an pin out). So, I will accept an answer if someone can tell me what may be the difference in these cables?
