First, the song ordering system
First of all, we must determine what kind of song ordering system to choose. Different choices determine the demand and investment cost of different equipment. At present, there are two options for the home song ordering system, one is the song ordering system installed on the computer, and the other is the song ordering system installed in the set-top box (similar to the set-top box of digital TV).
1. computer song ordering system;
Equipment: computer+song ordering software+audio and video output card
Computers can be modified with personal computers, and the configuration of general home computers can basically meet the requirements. Add a large-capacity hard disk, an audio and video input card, and install a set of song ordering software on the computer, and you can order songs.
There are two points to note here:
1). The size of hard disk capacity: the capacity of hard disk is related to the number of songs and the storage method of songs.
2). There are two kinds of video input cards: one is the video output function, which can output the video to the video card of the TV (with this card, the audio is output through the sound card of the computer itself); The other is a DVD decompression card, which outputs audio and video.
This personal computer modified home song ordering system has low cost, but it is inconvenient to install and debug.
2. Set-top box song ordering system:
Equipment: set-top box song ordering machine (embedded song ordering system+hard disk with songs)+song ordering screen (or mobile phone or tablet computer)
Second, the sound system
The equipment of home audio system includes power amplifier, speaker (subwoofer), microphone (microphone) and audio.
