Today's KTV on-demand systems are based on computers or computer motherboards. Video on demand (VOD) actually needs to process huge amounts of data, so it requires high hardware configuration. However, due to cost reasons, most computer VODs use relatively low hardware configurations. The outstanding problems are: the system is easy to crash, the after-sales service is heavy, the after-sales service costs are high, and most of the money earned in the early stage. They all went into the after-sales service, and the opinions of customers were also great.

Embedded systems are specialized systems developed for a specific electrical function. All hardware and software are designed around this particular feature and are not universal. Just like the control system of a special rocket, the control system of a machine tool, etc., because it is a special solution, the mature embedded system itself has high reliability.
The hardware and software system of the embedded jukebox is completely developed according to the actual needs of KTV, shielding the cumbersome and useless part of the computer, abandoning the PC motherboard, using hardware decoding and playback, and overcoming the problem of crashing in principle, and realizing the real problem. High reliability. The computer itself is not specifically used for VOD. The computer VOD uses software decoding. The system needs to have excellent hardware configuration, including motherboard, CPU, memory, etc. If the hardware configuration is not ideal, the crash is a natural thing. The embedded jukebox is hardware-decoded, and there is no problem of system resource conflicts. Of course, it is very reliable. If VOD is like off-road, the ordinary computer VOD is like a van. It can run at high speed or run a mountain road. The embedded jukebox is like a professional off-road vehicle. It is specially used to run mountain roads.
The latest is the embedded jukebox solution based on ARM architecture.
The ARM-based embedded jukebox has the advantages of low cost, small size, easy maintenance, stable performance, and low heat generation. The current CPU architecture of the ARM architecture is getting higher and higher, and the performance is getting stronger and stronger. Compared with the X86, there is basically no big gap, but both in terms of cost and volume and design difficulty, X86 Compared to both have a very big advantage.
The ARM-based jukebox solution is as simple to install as a regular DVD, does not require professional installation and debugging, does not require wiring, and is plug-and-play.
The biggest advantage of the ARM-based embedded jukebox is that it completely eliminates the phenomenon of crashes and is cost-effective. The ARM-based embedded jukebox is 60% cheaper than the similar computer version of VOD, and the system stability is increased by several times.
The ARM-based embedded jukebox supports dual-screen display:
The embedded jukebox solution of Shanghai Chenhan Electronic ARM architecture adopts the CPU of Freescale i.mx6 series, the CPU of Freescale i.mx6 series as the high performance controller of ARM Cortex-A9 architecture, the frequency has reached 1.2G, and there are multiple choices for single core, dual core, and quad core. Freescale i.mx6 can support split screen display of different content, so it can meet the requirements of KTV songs and large screen display, up to 1080P HD video playback. Implementing an embedded jukebox dual-screen vision solution on an ARM-based processor requires a very high level of technology accumulation. It requires sufficient experience in multi-channel display interfaces, chip and system design of different display devices. At the same time, the chip layer, the hardware layer, the kernel layer, the display framework layer, and the operating system framework layer need to have a clear understanding and research. If multi-channel asynchronous audio is combined, the multi-channel asynchronous video input is more complicated. In this technology, Chen Han Electronics has developed a patented bottom-up dual-screen vision framework based on the in-depth study of i.mx6 series processor display features and Android display unit framework, providing standard for application developers. Dual screen vision development interface, the main screen and the secondary screen can be switched at will, any android application can be implemented on the main screen. The display of multi-layer content can be realized on the secondary screen, and the display information such as text, picture, video, etc. can be superimposed, the display area can be divided, and the alpha transparency can be mixed between different layers, which fully satisfies the requirements of the entertainment application, and greatly reduces the realization. The technical threshold for the above entertainment applications.
An important feature of this technology is that it provides a seamless interface between the software interface provided by the dual-screen vision application developer and the native Android application development interface. The application developer can use the original class and API in the Android SDK on the secondary screen. Output display content, and like ordinary Android application development, you can use Java language to develop a dual-screen vision application, developers can use it in a short time, and development is very convenient.
With the development of top-notch multimedia technology experts and repeated experiments in various environments, we have finally made this highly reliable embedded jukebox solution popular in the market. Suitable for home theater, medium and small karaoke rooms, hotels, bars, clubs, sing-song karaoke rooms, factory entertainment halls, school recreation halls, etc.
With the continuous development of society and the demand for jukeboxes, the design based on X86 architecture will definitely be eliminated. Especially for home karaoke machines, portable and easy operation becomes the most basic requirement. The main high-performance and low-power advantages are bound to become the first choice of brand owners.
Which is the most welcome kid laptop for entertainment and online learning? 10.1 inch laptop is the best choice.
