What interface is hdml?
hdml's full name is High Definition Multimedia Interface, which means High Definition Multimedia Interface in Chinese. It is a fully digital video and sound sending interface that can send uncompressed audio and video signals.
High Definition Multimedia Interface (HDMI) is a fully digital video and sound sending interface that can send uncompressed audio and video signals. HDMI can be used in set-top boxes, DVD players, personal computers, televisions, game consoles, integrated amplifiers, digital audio and televisions and other equipment. HDMI can send audio and video signals at the same time. Since audio and video signals use the same wire, it greatly simplifies the installation of system lines.
HDMI is designed to replace older analog signal audio and video sending interfaces such as SCART or RCA terminals. It supports various TV and computer video formats, including SDTV and HDTV video images, plus multi-channel digital audio. Both HDMI and UDI without the audio transmission function inherit DVI's core technology "Transmission Minimized Differential Signal" TMDS, which is still essentially an extension of DVI.
HDMI also supports uncompressed 8-channel digital audio transmission (sampling rate 192kHz, data length 24bits/sample), as well as any compressed audio stream such as Dolby Digital or DTS, and also supports the 8-channel used by SACD 1bit DSD signal. In the HDMI 1.3 specification, support for ultra-high data volume uncompressed audio streams such as Dolby TrueHD and DTS-HD has been added.
The initiators of the HDMI organization include major consumer electronics manufacturers, such as Hitachi, Panasonic, Quasar, Philips, Sony, Thomson RCA, Toshiba, and Silicon Image. Digital Content Protection, LLC provides anti-copy protection technology related to HDMI interfaces. In addition, HDMI is also supported by major film production companies such as 20th Century Fox, Warner Bros., Disney, major consumer electronics manufacturers including Samsung Electronics, and many cable TV system operators.

What are the internal interfaces of a computer motherboard? Recommended introduction to the internal interfaces of a computer motherboard
Mar 12, 2024 pm 04:34 PM
When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V
Common programming paradigms and design patterns in Go language
Mar 04, 2024 pm 06:06 PM
As a modern and efficient programming language, Go language has rich programming paradigms and design patterns that can help developers write high-quality, maintainable code. This article will introduce common programming paradigms and design patterns in the Go language and provide specific code examples. 1. Object-oriented programming In the Go language, you can use structures and methods to implement object-oriented programming. By defining a structure and binding methods to the structure, the object-oriented features of data encapsulation and behavior binding can be achieved. packagemaini
Introduction to PHP interfaces and how to define them
Mar 23, 2024 am 09:00 AM
Introduction to PHP interface and how it is defined. PHP is an open source scripting language widely used in Web development. It is flexible, simple, and powerful. In PHP, an interface is a tool that defines common methods between multiple classes, achieving polymorphism and making code more flexible and reusable. This article will introduce the concept of PHP interfaces and how to define them, and provide specific code examples to demonstrate their usage. 1. PHP interface concept Interface plays an important role in object-oriented programming, defining the class application
Solution to NotImplementedError()
Mar 01, 2024 pm 03:10 PM
The reason for the error is in python. The reason why NotImplementedError() is thrown in Tornado may be because an abstract method or interface is not implemented. These methods or interfaces are declared in the parent class but not implemented in the child class. Subclasses need to implement these methods or interfaces to work properly. How to solve this problem is to implement the abstract method or interface declared by the parent class in the child class. If you are using a class to inherit from another class and you see this error, you should implement all the abstract methods declared in the parent class in the child class. If you are using an interface and you see this error, you should implement all methods declared in the interface in the class that implements the interface. If you are not sure which
Application of interfaces and abstract classes in design patterns in Java
May 01, 2024 pm 06:33 PM
Interfaces and abstract classes are used in design patterns for decoupling and extensibility. Interfaces define method signatures, abstract classes provide partial implementation, and subclasses must implement unimplemented methods. In the strategy pattern, the interface is used to define the algorithm, and the abstract class or concrete class provides the implementation, allowing dynamic switching of algorithms. In the observer pattern, interfaces are used to define observer behavior, and abstract or concrete classes are used to subscribe and publish notifications. In the adapter pattern, interfaces are used to adapt existing classes. Abstract classes or concrete classes can implement compatible interfaces, allowing interaction with original code.
What is the difference between interfaces and abstract classes in PHP?
Jun 04, 2024 am 09:17 AM
Interfaces and abstract classes are used to create extensible PHP code, and there is the following key difference between them: Interfaces enforce through implementation, while abstract classes enforce through inheritance. Interfaces cannot contain concrete methods, while abstract classes can. A class can implement multiple interfaces, but can only inherit from one abstract class. Interfaces cannot be instantiated, but abstract classes can.
Insight into Hongmeng system: actual function measurement and usage experience
Mar 23, 2024 am 10:45 AM
As a new operating system launched by Huawei, Hongmeng system has caused quite a stir in the industry. As a new attempt by Huawei after the US ban, Hongmeng system has high hopes and expectations. Recently, I was fortunate enough to get a Huawei mobile phone equipped with Hongmeng system. After a period of use and actual testing, I will share some functional testing and usage experience of Hongmeng system. First, let’s take a look at the interface and functions of Hongmeng system. The Hongmeng system adopts Huawei's own design style as a whole, which is simple, clear and smooth in operation. On the desktop, various
Inner class implementation of interfaces and abstract classes in Java
Apr 30, 2024 pm 02:03 PM
Java allows inner classes to be defined within interfaces and abstract classes, providing flexibility for code reuse and modularization. Inner classes in interfaces can implement specific functions, while inner classes in abstract classes can define general functions, and subclasses provide concrete implementations.
