High-Definition Multimedia Interface (HDMI)

HDMI
HDMI is a one-cable way to connect high-definition AV components and is currently the most common connection method used on Blu-ray players, AV receivers, cable/satellite set-top boxes, gaming consoles, and video displays such as plasma/LCD TVs and front projectors. HDMI can pass high-definition video and high-resolution, multichannel audio (including the DTS Master Audio and Dolby True HD soundtracks found on many Blu-ray discs) over a single cable, providing an easy, uncluttered way to connect your devices.
HDMI has been through many upgrades in its lifetime. You can read about previous versions through the HDMI Wikipedia page or at HDMI.org. The current spec, released in September 2013, is HDMI 2.0, which increases bandwidth up to 18 Gbps and supports the passage of a 4K/Ultra HD resolution at up to 60 frames per second. Other enhancements in the 2.0 spec include support for the 21:9 video aspect ratio, support for up to 32 audio channels and up to a 1536-kHz audio sample frequency, simultaneous delivery of dual video streams on the same screen, and simultaneous delivery of multi-stream audio to up to four users. HDMI 2.0 is now appearing on the new crop of Ultra HD TVs and projectors and will likely be the connection format of choice for any upcoming Ultra HD disc format. (Another connector you might find on a new Ultra HD component is DisplayPort. The HDMI 2.0 spec is backwards compatible with previous HDMI versions and does not require the use of new cables.
Speaking of cables, HDMI Licensing, LLC has defined five different types of HDMI cables; officially licensed HDMI cables should clearly identify their type on the packaging to help you select the kind you need:
Standard HDMI Cable: tested to reliably transmit a 1080i or 720p video resolution. This type of HDMI cable is fine for connecting a cable/satellite box or upconverting DVD player to an HDTV.
Standard HDMI Cable with Ethernet: offers the same baseline performance as the Standard HDMI Cable with an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking.
Standard Automotive HDMI Cable: supports up to 720p/1080i. Since an automotive system may be wired with one or more internal relays that can affect signal strength, the Standard Automotive HDMI Cable needs to send a stronger signal than other cables types, so it is tested to higher performance standards.
High Speed HDMI Cable: tested to handle video resolutions of 1080p and beyond, including 4K, 3D, and Deep Color. This type of cable is recommended for use with a 1080p Blu-ray player or gaming console, as well as new Ultra HD gear.
High Speed HDMI Cable with Ethernet: offers the same baseline performance as the High Speed HDMI Cable with an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking.
While HDMI is a very convenient way to connect devices, the technology is not problem-free. HDMI employs HDCP copy protection to protect the digital information transferred between devices; the connected devices must establish HDCP authentication in order to transmit the signal, which is sometimes called the HDCP handshake. If the handshake is unsuccessful, you may see a blue or otherwise discolored image, or you may just see snow on the screen. Handshake issues are less common than they were in the early days of HDMI, but they still occur. To re-establish the HDCP handshake between two devices, you can try disconnecting and reconnecting the HDMI cable at each end and/or powering down the components and restarting.
HDMI can also be less reliable over long runs. If your AV gear sits only a few feet away from your TV, then a basic, inexpensive HDMI cable will likely do the job just fine. However, if you need to run HDMI across the room to a projector or through walls to an equipment room, then you'll probably need to step up to a well-built active HDMI cable that boosts the signal to extend the range, up to about 100 feet. RedMere is one chipset used in some active HDMI cables. For even longer runs, consider an HDMI Extender Kit from a company like Gefen, Atlona, or WireWorld that can send the signal over CAT5/6, coaxial, or fiberoptic cable.

Phone memory card can not be formatted I do?

Many of my friends have encountered mobile phone memory card can not be formatted fault, but because of the knowledge of the phone's memory card can not be formatted know much, so that the memory card is damaged and discarded. In fact, mobile phone memory card can not be formatted to solve the fault is not complicated, let's learn together what is the phone memory cards and mobile phone memory card can not be formatted workaround it.


 Our phone itself has a certain amount of storage capacity, but in order to meet the needs of mobile phone users to personalize the phone's memory, many phones are set up external memory, which is what we usually refer to the phone's memory card. It can be used to store songs, movies, books, games, software and other data. Now available in common memory card into mmc, sd, minisd, memory stick, sm several.

  Card circuit is very simple, four data transmitted by a clock signal, the main role is to read the store, when the phone is switched on in a state we insert a memory card (a card control signal high to low) phone screen display SD card is inserted or removed and other tips, the actual maintenance often found not recognize the memory card, a lot of the fault lies in the deck, there are a variety of card holder, is most likely a bad seat enclosed card.

  To understand the phone memory card, we look at the memory card can not be formatted following specific solutions:

  Phone memory card can not be formatted in one: a new partition table.
  1, the memory card is connected to the computer, right-click My Computer - Manage - Computer Management.
  2 Click Disk Management under Storage on the left to determine disk information displayed memory card, such as disk 1, etc.
  3. Right-click the disk 1-- create a new partition, choose fat32, you will be prompted to create a success
  4, the final format of the memory card can be

  Phone memory card can not be formatted Method two: system file shredding.
  By anti-virus software tools: 360 security guards file shredding tool (of course other documents may also be pulverized) to mmc following system together shattered. Then you can normally complete the formatting.

  Phone memory card can not be formatted Method three: Delete system files.
  By deleting system files. There must be a strange file can not be deleted. Select the file, rename (the first is to change the extension txt, rar, mp3 these can) to remove this strange document, and then try to format.

  Phone memory card can not be formatted four: auto delete files.
  Plug in the memory card, double-click My Computer, and then press alt + t choose Folder Options - View -! Found (Show hidden files and folders) and select then find (hidden protected operating system files) front √ remove and then apply, and then point to determine at this time the right to open the memory card;!! find auto delete all the files, you can, and then safely remove the memory card and then plug in you can double-click.

Microsoft "forced" to upgrade Windows 10 operating system allows many users are tired, then there is no effective way to shut down Windows 10 upgrade remind it?


On Microsoft's official "notification and how to manage Windows 10 upgrade options," support page, Microsoft said, by editing the registry, you can easily prevent the system from Windows 10 upgrade notification bar pops up a reminder .

Specific steps are as follows:

  1. Open the Registry Editor

  2, navigate to HKLM \ SOFTWARE \ Policies \ Microsoft \ Windows \ WindowsUpdate

  3. Find a Dword called DisableOSUpgrade

  4, the value is set to 1 Dword

  5, if Dword does not exist, create the Dword, and the value is set to 1.

  It is worth mentioning that this feature is not just developed, back in July when it released Windows 10 can be used, but now it was discovered.

DC-DC Converter Basics

ABSTRACT


                      A DC to  DC converter is a device that accepts a DC input voltage and produces a DC
output voltage. Typically the output produced is at a different voltage level than the input. In
addition, DC to DC
converters are used to provide noise isolation , power bus
regulation , etc. This is a summary of some of the popular DC to DC
converter topolopgies

1. BUCK CONVERTER STEP DOWN CONVERTER

1.1 Transition between continuous and discontinuous
1.2 Voltage Ratio  of Buck Converter (Discontinuous Mode)


2. BOOST CONVERTER STEP UP CONVERTER

3. BUCK BOOST CONVERTER

4. CONVERTER COMPARISON

6. Isolated  DC DC Converters
