It can be made up of S-VHS, satellite TV and video player. With the current technology development, the video disc player is the most mature one. Video player can be roughly divided into LD, VCD, super VCD, DVD several types. LD has higher picture definition and better audio quality, but in our country, program software is less and has been eliminated. VCD and super VCD of the two products in the strict sense does not have the ability to provide high-quality video for the home theater, the computer industry in the transplant for transition products requires a stage in Chinese market, has completed its mission, will gradually fade out the market. At this stage, the most suitable as a home theater audio source only DVD disk machine, it is Blu ray DVD disk machine and real digital TV before the end of the market products. Large capacity, high definition, perfect sound quality is its main feature.AV power amplifier is the center of audio playback, which is characterized by multi-channel sound reproduction. When it comes to multichannel playback, it's inseparable from surround sound standards. Now popular surround sound standards are: 1, Dolby directional logic (Dolby, Prologic) surround sound. 2, Dolby digital (Dolby Digital) surround sound. 3, DTS surround sound. 4, THX, Surround, EX surround sound (7.1 channel). 5, DTS-ES, Discrete surround sound (6.1 channels).A home AV power amplifier has at least Dolby digital surround sound decoding and playback capabilities.

Home theater equipment is divided into two parts video and audio. The video part is a very important part of the whole system. It is usually held by a large screen color TV or a projector. As the terminal of the home theater, the minimum standard of display equipment must be a color TV of more than 29 inches. The quality of the color TV itself needs not be demanding, but it is best to have a variety of circuits that can improve the picture quality. If the room and economic conditions permit, it is best to select high-quality front projectors (outside) plus on-line letter multiplier, which can greatly improve the visual area and clarity of the picture.
