NAB2014 Report

datePosted on 15:11, April 18th, 2014 by Many Ayromlou

DEKTEC: DekTec introduced the DTA-2180 low profile PCIe H.264 encoder. The DTA-2180 is a low latency — 150 to 600 ms — H.264 hardware encoder based on the Magnum chipset. It supports MPEG-2 and H.264 and up to 16 channels of audio. Audio can be encoded as AC-3, AAC or MPEG-1 Layer 2. The DTA-2180 offers a 10 bit 4:2:2 option for contribution encoding.The DTA-2180 has a 3G –SDI and HDMI input and an ASI output. The compressed stream output — TS encapsulated H.264 or mpeg-2 — is also available on the PCIe for real time streaming, processing and recording.1

NIMBUS: The WiMi6400T and WiMi6400R provides high quality Full HD encoding/decoding function with low latency of 40ms for encoding and decoding, each.Read the rest

Hauppauge Broadway: OTA ATSC streaming for iOS devices….

datePosted on 23:27, January 16th, 2011 by Many Ayromlou

Yep, just like the title says, hauppauge has announced the Broadway, a new “set-top” aimed at iPhone, iPad and iPod touch users. The hardware streams live OTA HDTV to an Apple handheld after first compressing the video using H.264. The resulting media can be delivered locally over Wi-Fi, or to a remote place using any Internet connection. Over-The-Air ATSC signals can be captured using a built-in ATSC tuner, while cable is supported through clear QAM. Pricing is a bit steep at $199 and the box is scheduled for February release.

Elgato turbo.264 HD video encoding coprocessor review…….

datePosted on 18:00, January 15th, 2010 by Many Ayromlou

I just picked one of these babies up from the apple store and after testing it a bit for the past hour, I have one word for it: WOW. This little guy is no gimmick, it’s zippy as hell and it does exactly what they say it would. The details for the device are on Elgato’s Website, but this is just a mini review of the tests I ran against a couple of software encoders.

Here is my setup:

- Mac OSX 10.5.8 with latest updates running on a 2.16Ghz Intel Core 2 Duo Black MacBook w/ 2 GB 667Mhz DDR2 SDRAM.
- Test input file was a HD movie I grabbed from vimeo through BT. It’s 12.5 minutes in lenght.… Read the rest

So you think you are getting an HD quality signal……

Hehehe, yeah people used to make fun of me when I mentioned how much I hate Robbers (Rogers) and Compressview (Expressview) services in Canada and that I would refuse to pay for their so called HD premium service because I KNOW what kinda abuse the content goes through before it gets to my TV. I’ve since switched to OTA (Over The Air) HD and yes I don’t get all the Discovery/Food/Bravo channels in HD, but then again what is your definition of HD I ask?

Anyways, for those of you who’re still entrusting Robbers, Compressview and/or others, have a quick peak at this article on Popular Mechanics website.

And now a bit of Engineering brought to you by the letter E

As some of you might know I’ve been setting up my OTA (Over The Air) HDTV gear for the past couple of months and learning all about Antenna design, gain, amplification, directionality and such…..Lots of fun/confusing stuff. Well today I came across this article on digitalhome.ca that describes how a bunch of guys got together and using digital modeling improved the original Gray-Hoverman Antenna design. And if that wasn’t enough, they’ve released their design completely under GPL……Bravo. They’ve truly built the Super Antenna and in true spirit of engineering have shared their results/designs. So go grab some coat hangers, set aside 30 minutes of your life and get off the bandwagon and save some money by grabing your HD over the air for FREE….Like it’s supposed to be.Read the rest

CineForm Direct-to-Disk Recorder

datePosted on 12:10, December 10th, 2007 by Many Ayromlou


I have to admit CineForm is one of my favourite companies out there. I’ve visited them once and they are the nicest bunch of engineers you’ll find on that side of the rockies :-). Aside from their famed CineForm Codec (which btw is awesome), they have just released the specs and conceptual drawings for what will probably be the coolest gadget at next years NAB ;-).

They anticipate developing multiple members in the recorder product family – each targeting different recording needs. This first device targets HDV camcorder users and offers the ability to bypass the highly-compressed MPEG format. The features specification is below. They also imagine a sister device that would support single-link and dual-link HD-SDI recording.
