How to connect a computer to a HDTV and have the audio go through the TV speakers?

How do I connect my computer to my HDTV so that the sound comes through the tv speakers. I bought a HDMI cable (my computer has HDMI out) but when I connected this cable I got picture, but no audio. My PS3 is connected with a HDMI cable also and I do have audio with it. I don't know what I'm missing.

Antenna issues- loss of signal with a DIY antenna Answered

Recently, I have made an HDTV antenna using a video from youtube (http://www.youtube.com/watch?v=EWQhlmJTMzw) and some inspiration from Instructables that I have read. The issue i'm having is that I am slowly losing my signal. I noticed the rust build-up on the end of the fins of it and I have cleaned them up, but it didn't help. Another issue is that I can't seem to pick up a local channel, yet on clear nights I pick up channels from 100 miles away. ( I live in Winchester, Ky and I pick up Cincinatti channels) Anyone have any ideas? Maybe re-work the metal parts with a different type of metal? Maybe a few ideas on different designs?

iMac to Toshiba HDTV wireless problem. Answered

How do I manage to get Netflix, Hulu, etc from my iMac to my Toshiba HDTV wirelessly. I have a Trendent TEW-647GA adapter which brings my wifi signal to where my TV is sitting. But it doesn't have a connection so as to enable me to hook it to the TV.? The adapter would have been very useful if it had a HDMI connection capability but it doesn't. I am using ATT's 2 Wire modem which is connected to my computer with Ethernet and it also is a wireless modem. I am a newbie at this so any help at all is very much appreciated.

Picture in picture is faster than TV screen?

I was just watching the Blackhawks win the Stanley Cup (woo), and my dad turned on picture in picture so we could see what another channel was broadcasting, but as a default it started on the same channel. The weird thing was the picture in picture was a full 1-2 seconds ahead (the audio was synched correctly with the main picture). It's an HDTV connected to a cable box. This is pretty much the least important question ever, but I found it weird and wondered if anyone had any ideas.

Help me pick a laptop?

Ok, so I'm getting a laptop and I'm not sure if one exists with what I want but if it doesn't fine I'll wait for it to exist.  The laptop must have a core i7 processor, blu-ray writer, 1920x1080 resolution, an HDTV tuner, and a backlit keyboard.  Here's what I've been looking at: Acer Aspire 8940g, HP dv8t and dv7t, Dell XPS 16.  So I'm just wondering if you can actually buy such a laptop I know Acer has said that they offer all these options but I can't find such a laptop anywhere on the internet.  Thanks for the help! And P.S. I don't want an Alienware laptop.

How can I get from HDTV optical digital to analog volume controlled earphones??

My Toshiba HDTV has only one audio output, Digital Optical. I am hard of hearing and need to use earphones with volume control to listen while others are in the room. I believe a small, single purpose audio amp with digital, optical input and maximum volume analog output would do the job. No one builds such a device. The ones available have multiple options and resulting high price. I know how to read, BUT NOT DESIGN, circuits. I would prefer a design that would work off of a standard available "wall wart"/ Can anyone provide such schematic?

i need help picking out a TV?

i want to buy a 29-37 (preferably 32) inch TV that has Internet Apps; (maybe 3D); at LEAST an 80,000:1 contrast ratio, (maybe 120 Hz or more, but I'm not very picky as long as there is no flicker on the image); and 1080p full HD. i found many models rounding at about $900 (without 3D, of course), little pricey huh?   my QUESTIONS: 1) picture-wise, what is the difference between "back-lit LED", and "edge lit LED" and is there any other technology i have not heard of yet (NOT including back projection of a projector)? 2) which would be the best choice LED, LCD, or Plasma, (of if cheap, small and light enough,      back projection DLP)?         (i don't really care about efficacy, but i do want one with a good lifespan; really bright colors     (like led or plasma) and good contrast, and has deep "black" blacks; hopefully 1080p, but     ill settle for 720p, less than 8 ms response time; has a great viewing angle; and last and     certainly not last, one that is under the $1600.00 price tag!) 3) whats the difference in the picture quality with edge-lit-LED and back lite-LED? (i know the led      placement in each corresponds with the type of led tv it is.) ____________________________________________________________________________ right now, i have a 19 inch CRT 4:3 aspect ratio (i am guessing 480p res) the TV itself is a "CurtisMathes-Tronics" brand (i never heard of it) (model # "CM 19022S"). its OK. it works, but its getting too small for me, and after i bumped into some money last summer ($700) at the peek and i am thinking saving for a "state of the art" HDTV! next year, with my summer job, i should have $1500 to spend.

how can I build a Wireless Display/Transmitter that don't need a receiver?

On my school's cafeteria there are 3 big HDTVs. What I wanna do is, at lunch time that everybody in in there, hijack the 3 tvs' signals and replace them with a funny video. (Also, later on I can use it on my own house) I don't know if you've heard about those headphones that you put on and they catch the signal from the nearest TV so, at night when everyone else is sleeping you can listen to it without disturbing people. I was thinking about using something like that! Of course, doing the opposite. I don't know what's the 'official' name. Some people call it a 'low power transmitter' and other people call it 'Wireless Display (WiDi)'. Hopefully you'll know and if you do, please let me know. I just want SOMETHING like the iTrip, you know? That the radio station IS the receiver so I won't have to build the actual receiver. I want to build/buy a transmitter that will adapt to my laptop or my iPhone so when I click play on a video, it will show on the nearest TV or TVs without the necessity of them having a receiver. That the actual TV, tv's signal, channel, whatever IS the receiver so I can carry it around without the necessity of putting something on the other end whenever I wanna watch something on a different TV. I'm really hoping I made myself crystal clear and didn't confuse you. I'm also hoping you could give me your advice, or if you have a better method.

DB8 Antenna page won't let me log in

Hello, I enjoy Instructables.com and set up a username/password quite some time ago so I could view 'ibles on a single page. This morning, I followed a link from Lifehacker.com to https://www.instructables.com/id/Build-a-Large-DB8-HDTV-Antenna-Big-Bertha/.  Usually, when I do that, the upper right corner says "You INBOX(0) CUSTOMIZE..." -- that tells me I'm logged in. When I hit that page, I just get the "Login" button.  If I click "Login", my username and password show up (Firefox remembers them), I click "Login" again, and it goes back to the "Login".

Gaming is Changing

I used to like console gaming because systems rarely/never costed more than $300, it was simple, and everybody had the same stuff. There were no expensive HDTVs, broadband-requiring/expensive online play, the fanciest peripheral was the rumble pack, and your console didn't do anything except light up a power light if there was no game in it.I'm not rich, my parents have never owned a house, and with all the fancy crap that consoles require and do today, I can't afford even a Wii (not that I'd want one, the novelty has worn off). I'm not saying all these improvements in gaming are bad, but for someone like me, I just don't have the money for a shiny new 360, or even high-speed internet (I live on an acerage and there's no cable in the country) for online muiltiplayer/communication.For now, I'll just have to fondly remember having home tournaments playing Star Wars Episode 1 Pod-Racer on N64 with my friends.What do YOU think about gaming today?

What Version of HDCP Does the Xbox 360 Require? Other HD Questions...NERD ALERT!

I might get an Xbox 360 some day (say I win the lottery). My HD TV has support for version one of HDCP (High Definition Content Protection, supposed to protect against copying, yeah right). Is version one sufficient to use an Xbox 360 with my TV? Also I only have one DVI port on my TV, no HDMI (it's two years old, my dad kinda jumped into it). We have our HDTV Star Choice satellite receiver hooked up to that, so I don't wanna have to swap out the satellite for the 360 everytime I wanna play in HD (I have a CRT TV in my room which I usually play games on). Can I get a Y shaped switcher thingy for my TV? I know DVI, unlike HDMI, doesn't support all in one audio and video in one tiny HDMI cable. Does the 360 have a seperate output for audio, too?

Creative Advertising that Works

When the first ad for Sony's Bravia came out I loved it. It was set in my city of San Francisco and the sheer beauty of seeing hundreds of thousands of bouncy balls going everywhere was amazing. I forwarded the link to lots of friends and we all talked about it. I still watch my old 20" CRT at home for movies, but I do have a soft spot for Bravia should I ever decide that I really and truly need a big HDTV, which isn't likely any time soon.So when the second ad came out I was thrilled. It had exploding paint and colors, but it lacked the magic. It felt forced and the fact that elements were digitally removed took away the handmade quality that really helped the first one connect.Yesterday, the third one was released online. I think it's a step back in the right direction. I highly encourage you to check out the official link, but here's a youtube version with crappier color.What do you think? If you haven't seen the other ads, check them out first. So here's the order: - bouncy ball ad from 2005 - paint ad from 2006 - bunny ad from 2007

How to use HDMI Receiver/Transmitter IC to create intermediate device ? Answered

Dear ALL, In the beginning Here're 2 links for something similar I found while searching. 1) arduino.cc/forum/index.php/topic,142845.0.html 2) www.overclock.net/t/1347100/diy-rgb-ambilight What I wanted to do is to Create "In Middle Device" between Video source (DVD or gaming console) & Video Receiver (HDTV). All What I want is to override some of the data sent/received between them. Like the required resolution, image width & height, Audio & so on. Here's an example scenario hoping to make things clearer: Assume I have DVD Player & I have 2 "LET TV" screens. Now I want to split the video images sent from the DVD player into 2 for the 2 screens. Got the idea? it's like extending the screen. Besides I want the data sent from the TV in this case I need to define the width & height of the tv as both TVs together! if you get what I want! I found a lot of things online .. here're some links. But I just need some guidance from those who know more about HDMI, video processors! 1) processors.wiki.ti.com/index.php/TI81XX_PSP_HDMI_Driver_User_Guide 2) processors.wiki.ti.com/index.php/Sii9022a_HDMI_transmitter_driver Thanks in advance, Kind regards

DIY DVR (PVR ?)

No, not the mythTV variety, but the real deal. I've been messing with uCLinux on various chip, which led to a vague daydream that I sketched out on the train today. These are my notes on a personal DVR. I say personal because its design for MY needs, and not the typical user. It also happens that no commercial DVR will meet these specs without being mired in lawsuits (see replayTV). Why an embedded solution and not MythTV? I've had mythtv boxes, they can be a lot of fun, and a lot of frustration. Mostly, I don't have room for a second computer, I don't want to use a ton of energy to record a few programs, and no matter where it ends up in my apartment, I will be able to hear it at night. MyDVR: I already watch all my TV on the computer. Either by TV tuner or Xvid. I don't need a Tivo style DVR that will play back content on a TV with a nice menu display. I need a mass storage device that records TV shows. I want Xvid. MPEG2 is huge. Its also kinda ugly. I really really like the look of the XVID codec. It takes a reasonable amount of space for a decent encode (~178 meg per ~20 minutes HDTV). I want multiple tuners...I mean, what if there are two (or five) programs to record simultaneously? Basic design: A motherboard with 32 bit CPU running uClinux (probably a chip from Freescale). These usually have USB and an ethernet MAC (but no PHY). USB 2.0 mass storage device emulation on the USB port. This way the unit can be hooked up to a PC for easy video extraction. This might also have some configuration abilities, but that would require a custom mass storage controller driver - YUCK! Ethernet with HTTP server for show scheduling. IDE interface to a big hard drive. The tuners and encoders would be on add-in cards. The add-in cards would have: 1. A tv tuner. 2. A DSP with xvid encoding. 3. Probably a small uC to control the DSP and tuner. Whats already in my knowledge domain (stuff that I already know about -or- could I really do it?): 1. I've been messing with uClinux for a while. What fun. 2. USB mass storage controller implementations are numerous. check. 3. Embedded HTTP server - check. But I have not routed a PCB using an external PHY. This looks messy. Perhaps a ENC28J60 instead? 4. I've been reading up on some XVID DSP implementations. There are also some commercial MP4 chips, but I bet they're pricey! 5. I picked up a bare PAL tuner at the surplus shop. Time to play. There are a few things that make this project easier than a Tivo clone. There is no video output. No need to do fancy display overlays synced to the incoming/decoding video stream. This is encode only - no need to load, decode, and display the XVID. I'm kinda testing the waters on this project. I'm going to get some DSPs and try to do real-time XVID compression. Also, I need to figure out the tuner card. Any suggestions within the scope of this project would be awesome! Especially if you've worked with uClinux and have a processor recommendation.
