Canon 5D Mark III firmware update, Fix improved AF, HDMI output

Canon 5D Mark III firmware update

If your camera arsenal includes a 5D Mark III, prepare to get your download on. Earlier today, Canon released a major firmware update for the hit DSLR — version 1.2.1 enables clean, uncompressed HDMI output with simultaneous LCD display and recording to CF or SD cards, along with cross-type autofocus for apertures as small as f/8, bringing that aspect of AF capability in line with the EOS-1D X. You’ll be able to take advantage of improved autofocus performance even when using an f/5.6 lens with a 1.4x extender, or an f/4 lens with a 2x extender. On the video front, version 1.2.1 will let you boot an uncompressed YCbCr 4:2:2 feed to an external recorder, enabling your pick of codecs and frame rates, while also eliminating arbitrary limits on record time. The free download, available for recent versions of Mac OS and Windows, Canon 5D Mark III firmware

Nikon D7000, Playback

There are a couple of options for reviewing your video once you have finished recording. The first, and probably the easiest, is to press the Image Review button to bring up the recorded image on the rear LCD, and then use the OK button to start playing the video. The Multi-selector acts as the video controller and allows you to rewind and fast-forward as well as stop the video altogether

If you would like to get a larger look at things, you will need to either watch the video on your TV or move the video files to your computer. To watch low-res video on your TV, you can use the video cable that came with your camera and plug it into the small port on the side of the camera body (Figure 10.3). To get the full effect from your HD video, you will need to buy an HDMI cable (your TV needs to support at least 720HD and have an HDMI port to use this option). Once you have the cable hooked up, simply use the same camera controls that you use for watching the video on the rear LCD.

If you want to watch a video on your computer, you will need to download it using Nikon software or an SD card reader attached to the computer. The video file will have the extension .avi at the end of the filename. These files should play on either a Mac or a PC using software that came with your operating system (QuickTime for Mac and Windows Media Player for PC).

Canon PowerShot G12, Watching Your Videos

There are a couple of different options for you to review your video once you have finished recording. The first is probably the easiest: Press the Playback button to bring up the recorded image on the LCD screen, and then use the Set button to start playing the video. The Left/Right buttons act as the video controller and allow you to rewind and fast-forward as well as stop the video altogether.

If you would like to get a larger look at things, you will need to either watch the video on your TV or move the video files to your computer. To watch on your TV, connect an HDMI cable to the HDMI Out port, or connect the video cable that came with the camera to the A/V Out/Digital port (Figure 11.4).

Once you’ve connected to your TV, simply use the same camera controls that you used for watching the video on the LCD screen.

If you want to watch or use the videos on your computer, you need to download the images using the Canon software or by using an SD card reader attached to your computer. The video files will have the extension “.mov” at the end of the file name. These files should play on either a Mac or a PC using software that came with your operating system or that can be downloaded for free (Apple’s QuickTime for Mac and Windows is available at www.apple.com/quicktime/download/).

HDMI Licensing, LLC

HDMI Licensing, LLC, of Sunnyvale, California, promulgates the HDMI specifications. In 2009, they published the new HDMI 1.4 that was discussed in Appendix A5. HDMI cabling is typically used between the STB or BD player and the TV display. This upgrade has been viewed as one of the key developments to enable 3DTV. Of all the new HDMI 1.4 features, 3D is reportedly getting the most interest from the broadcasters.

The HDMI 1.4 work grew out of interactions between the HDMI Licensing group and a related working group in the CEA that owns CEA 861. There are improvements expected with new silicon interface chips as these support higher transfer rates on the interface, but the short-term goal is also to have existing equipment be as functional as possible because without HDMI support, one cannot readily deploy 3DTV. The HDMI Licensing group is also relaxing its specifications so that many existing STBs and TVs do not have to handle a variety of previously mandatory formats, often beyond their processing capabilities or needs. Instead, they can handle stereo 3D broadcasts in the top/bottom format with a firmware upgrade.

Consumer Electronics Association (CEA)

The CEA is the preeminent trade association promoting growth in the $172 billion US consumer electronics industry. More than 2000 companies are members of the CEA, including legislative advocacy, market research, technical training and education, industry promotion, and the fostering of business and strategic relationships.

At recent CEA Industry Forums (2009), the focus has been on consumer electronics retail trends (e.g., changes in channel dynamics), 3DTV technology, green technology, and social media. CEA takes the (tentative) position that the 3DTV technology is demonstrating clear success at movie theaters and will gradually evolve into other facets of consumers’ viewing habits. But the guidance is that the industry needs to have reasonable expectations for 3DTV. 3DTV is gaining momentum, as covered in this text, but may not completely reach critical mass for several years. CEA recently observed that the top trends and technologies likely to prominently feature at upcoming international CES events are as follows: interactive TV topped the list as a trend to watch with a variety of partnerships, widgets, menus, and new ways to manage content across screens likely to generate “buzz” at upcoming CES trade shows; and 3DTV also will be a big trend, with the question of whether 3D glasses or an alternative solution will emerge as the most viable option. E-books and Netbooks were also highlighted as top 2010-and-beyond CES trends [17].

CEA is developing standards for the interface for an uncompressed digital interface between (say) the STB (called source) and the 3D display (called sink); these standards will need to include signaling details, 3D format support, and other interoperability requirements between sources and sinks. In 2008 CEA started standards work aimed at enabling home systems to play stereoscopic 3DTV. The group’s first step was to upgrade the interconnect standard used in the High-Definition Multimedia Interface (HDMI) to enable the cable/interface to carry stereo 3D data. Specifically this entailed an upgrade of the CEA 861 standard (A DTV Profile for Uncompressed High-Speed Digital Interfaces, March 2008) that defines an uncompressed video interconnect for HDMI. The standard defines video timing requirements, discovery structures, and a data transfer structure (InfoPacket) that is used for building uncompressed, baseband, digital
interfaces on DTVs or DTV monitors. A single physical interface is not specified, but any interface implemented must use Video Electronics Standards Association Enhanced Extended Display Identification Data (VESA E-EDID) for format discovery. CEA-861-E establishes protocols, requirements, and recommendations for the utilization of uncompressed digital interfaces by consumer electronics devices such as DTVs, digital cable, satellite or terrestrial STBs, and related peripheral devices including, but not limited to DVD players/recorders, and other related sources or sinks. CEA-861-E is applicable to a variety of standard DTVrelated high-speed digital physical interfaces such as Digital Visual Interface
(DVI) 1.0, Open Low Voltage Differential Signaling Display Interface (LDI), and HDMI specifications. Protocols, requirements, and recommendations that are defined include video formats and waveforms; colorimetry and quantization; transport of compressed and uncompressed, as well as Linear Pulse Code Modulation (LPCM), audio; carriage of auxiliary data; and implementations of the VESA E-EDID, that is used by sinks to declare display capabilities and characteristics.

At press time, CEA was also working on creating standards for 3DTV active and passive eyeglasses, metadata, on-screen displays, and user controls. A CEA group set up in 2009 was working on a standard for infrared signals used to control active shutter glasses; the group developed a requirements document and published a broad call for proposals in early 2010. The CEA also has a task group studying how to place captions in 3D space; the group was expected to issue a call for proposals in early 2010.

Home Theater Cable Guide

The past decade has been an amazing time for home theater enthusiasts. Improved manufacturing techniques and global
market competition has brought high-end A/V equipment into the mainstream. Competition among flat panel TV manufacturers has been particularly fierce. However, to keep costs down to a minimum, many of these products are shipped with near useless user manuals and throwaway A/V cables.

Home Theater Cable Guide

A quick glance at the back of a typical HDTV can be quite intimidating.  There will often be 10 or more types of  connections, many of which appear redundant. So what type of connection yields the best picture or sound quality?
What kind of cable is required? We created the Amphenol Cables on Demand Home Theater Cable Guide to answer these A/V questions.

Cable Guide

HDTV

HDMI

HDMI

The HDMI or High Definition Multimedia Interface is the A/V connection of choice on the latest generation of home theater equipment. HDMI supports high resolution digital video with resolutions up to 1920×1080 (1080p) as well as multichannel digital surround sound over a single low-profile cable. Since HDMI is a digital interface, interference problems such as ghosting, snow, and hum are eliminated entirely. If you have HDMI inputs on your HDTV, you must use an HDMI compatible signal source to take advantage of them. All new HDTV compatible cable and satellite set-top-boxes come standard with HDMI; as do the new HD-DVD and Blu-ray Disc Players.

HDMI cables must be built to extremely tight tolerances in order to support the bandwidth requirements of today’s video sources. We use our 70+ years of interconnect manufacturing experience to ensure these strict tolerances are met. Amphenol HDMI cables are designed to the latest specification: HDMI 1.3. For those running 1080p, we recommend our Premium 1080p Certified HDMI cable series.

SVGA

SVGA

Now that the personal computer has become the centerpiece for storing movies, music, and pictures, it’s no surprise that the SVGA connection has migrated over to the average HDTV. Now, with a simple cable, you can play PC based video games or browse the web on the big screen. Amphenol SVGA cables feature precision-terminated HD15 connectors and double-shielded coax; perfect for high-bandwidth 1080p HDTV signals. We recommend SVGA cables with Ferrites for commercial installations.

Component Video

Component Video

The Y’PbPr analog component video connection made its major debut with the release of the DVD player in the mid 90s. Shortly thereafter, component video became standard equipment on nearly every HDTV and home theater projector.
Although component video does not quite meet the performance level offered by HDMI, it still reliably supports 1080p true high definition video content. We recommend component video cables for use with DVD players whenever possible to support the Progressive Scan feature. RCA audio cables are not suitable for component video use. Proper component video cables are color coded in red, blue, and green.

S-Video

The S-Video or “separate video” connection splits the analog video signal into a color component and a brightness component. S-Video is the preferred connection method for use with standard definition (480i) content. S-Video connections were often considered a premium on older tube TV’s, as they delivered a sharper picture from sources like S-VHS VCR’s, cable boxes, and satellite receivers. S-Video has the distinction of eliminating the problem of dot crawl, which consists of animated checkerboard patterns that appear along vertical color transitions. All Amphenol S-Video
cables are fully molded and shielded for exemplary performance and reliability. Premium Gold version available.

Composite Video

Composite Video

Composite video is perhaps the most widely used analog video interface found on consumer electronic equipment. A composite video connector can easily be located by its yellow color. It is called composite video because the color, sync, and brightness information is all combined into a single signal. Composite video is convenient and easy to work with since it demands minimal bandwidth and can be used over common 75 ohm coaxial cable. Composite video is always recommended for use with laser disc players, but is generally a lesser choice for other equipment if an S-Video,
component, or HDMI connection is available.

RF Audio / Video

RF Audio / Video

An RF signal combines both video and audio and modulates it onto a TV channel. If you have to turn the TV to channel 3 or 4 in order to watch your cable box or VCR, you are likely using an RF connection. We do not recommend using the RF connection on new A/V equipment unless absolutely necessary. If you simply need to hook up a VCR to a spare TV, this connection will work fine. Our special thin-line RF cables feature low-profile F connectors for maximum installation flexibility.

TOSLINK

TOSLINK

The TOSLINK interface was initially developed by Toshiba as a low cost method of digitally linking CD players and stereo receivers. As digital surround sound entered the home market, TOSLINK was adapted to handle the new format. TOSLINK ports were soon added to cable/satellite boxes, DVD players, and game consoles. The audio delivered via TOSLINK offers superior fidelity and is completely immune to interference due to its fiber optic design. We recommend using a digital connection like TOSLINK whenever possible. TOSLINK ports are easily recognized by their distinctive
red glow.

Stereo RCA

Stereo RCA

Analog Stereo RCA audio connections are widely implemented. Nearly every piece of home theater equipment on the market is equipped with one or more sets of Stereo RCA jacks. Stereo RCA connections are an ideal choice for use with devices that do not support digital surround sound such as CD players and VCR’s. To fully capture the multi-track digital surround sound embedded on most DVD’s and HDTV shows, a digital connection such as TOSLINK is required. Amphenol Stereo RCA cables are properly impedance matched for flawless audio reproduction.

3.5mm Mini-Stereo

3.5mm Mini-Stereo

The 3.5mm Mini-Stereo connection, often called the headphone jack, is commonly installed on portable electronic devices such as MP3 players and handheld games. Many home and car stereos now come equipped with a 3.5mm Mini-Stereo auxiliary input jack. Our 3.5mm male / male cable is perfect for connecting your portable device to this input jack. If you need to extend a pair of headphones or another cable, use our 3.5mm male / female cable.
