Apple HD iPad 3 unveiled, coming to Canada March 16

Wednesday, March 7th, 2012

Apple Inc. pulled back the curtains on the third generation of its tablet renaissance-inspiring iPad on Wednesday at a special event in San Francisco.

The new device includes many of the features which have long been rumoured to be in the works, including a high-resolution screen and the ability to connect to advanced 4G cellular networks. All three major Canadian wireless carriers — BCE Inc.’s Bell Canada unit, Rogers Communications Inc. and Telus Corp. — will be offering the new iPad for the same price as the iPad 2 starting March 16.

Voice dictation is also coming to the iPad through a new key on the touchscreen keyboard. However, the feature appears to be scaled down from the voice activated “Siri” digital assistant Apple introduced with the iPhone 4Slast October.

Other new iPad features include an iSight camera capable of recording high-definition (1080p) video and capturing 5-megapixel still images. Apple said the A5X processor used to power the new iPad is “twice as fast” and offers “four times the performance” as the Tegra 3 chip found in the iPad 2.

To help clear iPad 2 inventory, Apple also announced a US$100 discount on iPad 2 models. Canadian iPad 2 pricing now starts at $419 for the WiFi-only 16GB models.

By introducing a third iteration of the iPad while rival products remain at the first-generation stage represents an attempt by Apple to maintain its dominance in the increasingly cutthroat mobile market. Manyexisting iPad owners are expected to buy the new version in addition to first-time tablet buyers.

More than 55 million iPads have been purchased around the world since the device was launched less than two years ago. The popularity of iOS devices, of which Apple has sold 315 million including iPhones and iPods, has already started eating into sales of the company’s core Mac computer line thoughApple is well known as a company unafraid to eat its young.

Apple also announced the latest version of its iOS operating system at the event, which is available immediately as a software update, and a new version of its Apple TV set-top box capable of supporting 1080p-level resolutions.

HDMI Cable Tutorial About HDMI

Wednesday, May 18th, 2011

To follow up my facebook article about HDMI pinouts (http://www.facebook.com/note.php?created&&note_id=211924685506768)

I thought I’d share a great source of information on coming technologies. I’m only including what I think is pertinent, there is a link at the bottom with the whole article if you’re interested!

How do consumers benefit from HDMI?
The new HDMI digital interconnect provides:

  • Superior, uncompressed digital video and audio quality
  • Simple, user-friendly connector that replaces the maze of cabling behind the entertainment center
  • Integrated remote control
  • A popular interface enabling the transmission of high-definition content. HDMI opens the floodgate of digital content from major motion picture producers

What is HDMI 1.3?

  • HDMI 1.3 allows the availability of a new mini connector for devices such as camcorders
  • The availability of HDMI 1.3 depends on your specific equipment.
  • All HDMI cables should be made using the largest gauge (AWG) wire with individually shielded pairs possible with top quality workmanship. This protects your signal from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI).
  • Increases single-link bandwidth to 340 MHz (10.2 Gbit/s)
  • Optionally supports 30-bit, 36-bit, and 48-bit xvYCC with Deep Color or over one billion colors, up from 24-bit sRGB or YCbCr in previous versions.
  • Incorporates automatic audio syncing (Audio video sync) capability.
  • Optionally supports output of Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers.[8] TrueHD and DTS-HD are lossless audio codec formats used on Blu-ray Discs and HD DVDs. If the disc player can decode these streams into uncompressed audio, then HDMI 1.3 is not necessary, as all versions of HDMI can transport uncompressed audio.

What is HDMI 1.4?

  • HDMI 1.4 was released on May 28, 2009, and Silicon Image expects their first HDMI 1.4 products to sample in the second half of 2009.
  • HDMI 1.4 increases the maximum resolution to 4K x 2K (3840x2160p at 24Hz/25Hz/30Hz and 4096x2160p at 24Hz, which is a resolution used with digital theaters);
  • HDMI 1.4 includes an HDMI Ethernet Channel, which allows for a 100 Mb/s Ethernet connection between the two HDMI connected devices;
  • HDMI 1.4 also introduces
    • an Audio Return Channel
    • 3D Over HDMI (HDMI 1.3 devices will only support this for 1080i)
    • a new Micro HDMI Connector, expanded support for color spaces
    • an Automotive Connection System.
  • HDMI 1.4 supports several stereoscopic 3D formats including field alternative (interlaced), frame alternative, frame packing, line alternative, side-by-side half, side-by-side full, 2D + depth, and 2D + depth + graphics + graphics depth, with top/bottom half and full formats to be added in January 2010.
  • HDMI 1.4 requires that 3D displays support the frame packing 3D formats at either 720p50 and 1080p24 or 720p60 and 1080p24.
  • High Speed HDMI 1.3 cables can support all HDMI 1.4 features except for the HDMI Ethernet Channel.

What is the life expectancy of HDMI?
HDTV uses less than 1/2 of HDMI’s available 5 Gbps bandwidth. With capacity to spare, HDMI can incorporate new technology advancements and capabilities long into the foreseeable future.

Does HDMI provide a secure interface?
HDMI, when used in combination with HDCP, provides a secure audio/video interface that meets the security requirements of content providers and systems operators.

What is HDCP?
HDCP stands for High-bandwidth Digital Content Protection. HDCP encrypts the digital signal to prevent it from being recorded. HDCP encryption / decryption takes place within your equipment. Check your equipment documentation to see if it offers HDCP. Cables simply pass the digital signal between the HDCP compliant equipment.

What are the advantages of HDMI over existing analog interfaces such as composite, S-Video and component video?

  • Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.
  • All Digital HDMI ensures an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-to-analog conversions.
  • Low-cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner.
  • Audio HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound.
  • Ease-of-use HDMI combines video and multi-channel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables currently used in A/V systems.
  • Intelligence HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality.

Is HDMI backward-compatible with DVI (Digital Visual Interface)?
Yes, HDMI is fully backward-compatible with DVI using the CEA-861 profile for DTVs. HDMI DTVs will display video received from existing DVI-equipped products, and DVI-equipped TVs will display video from HDMI sources.

Will current HD TVs and set-top boxes using DVI-HDTV be compatible with HDMI devices?
Yes. Currently there are TVs with DVI-HDTV inputs available from a variety of manufacturers. Those devices will be compatible with future HDMI-equipped products.

What types of video does HDMI support?
HDMI has the capacity to support existing high-definition video formats (720p, 1080i, and even 1080p). It also has the flexibility to support enhanced definition formats such as 480p, as well as standard definition formats such as NTSC or PAL.

Does HDMI accommodate long cable lengths?
Yes. HDMI technology has been designed to use standard copper cable construction at long lengths. In order to allow cable manufacturers to improve their products through the use of new technologies, HDMI specifies the required performance of a cable but does not specify a maximum cable length. Cables are expected to be lengths of up to 15 meters. As semiconductor technology improves, even longer stretches can be reached with fiber optic cables, and with active cable technologies such as amplifiers or repeaters.


How much better is 1080p than 720p?
225%! It’s a huge difference. The soundtrack also improvesby 50% with the new totally lossless, bit-for-bit Dolby True HD and DTS Master HD multi-channel audio content.
