The following is a list of HDMI-CEC commands:
One touch play:Allows devices to switch the TV to use it as the active source when playback starts
System standbyEnables users to switch multiple devices to standby mode with the press of one button

Design pattern, is the crystallization of the wisdom of software design, but also every developer should learn.Adapter mode: The interface of one class is converted into another interface that the customer wants, so that those classes that cannot work together because of incompatible interfaces can work together.The adapter pattern can be divided into class adaptation and object adaptation. In terms of the actual situation in the development, the object adaptation mode is relatively more, the fo

2. how DirectShow supports hardware
As you know, the Windows operating system isolates hardware operations to improve system stability. Applications generally cannot directly access the hardware. DirectShow filter works in user mode (the operating system privilege level is ring 3), while the hardware works in kernel mode (the operating system privilege le

Android 7.0 has added a new API to support quick operations and replies for third-party application notifications. For example, incoming calls may appear at the top of the screen as banners, and two buttons are provided for receiving and hanging up; information/social networking application notifications can also be directly opened on the keyboard

• System standby-enables the user to switch all devices to standby with one button press.
• Preset transfer-enables any tuner device to download the same set of presets as the TV.
It is used to auto configure a devices presets so no manual setup is required.

In the use of computers, we often have to use the printer, but in the specific use of many users will find Win7 flagship printer shows the overall look is not clear, very vague. So what are the causes of such problems? How to solve it? Let's look at the Win7 system printer fonts can not see the solution.
