Embodiment Construction

[0022] The central idea of ​​the design scheme of the present invention is that the slave control system can work independently from the master control system, expanding the scope and functions of the slave control system. During the initialization process of the master control system, the disc loading device can accept the slave control system. The control works; after the main control system completes the initialization, it can obtain information from the disc loading device and start playing the disc content.

[0023] The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

[0024] like figure 1 As shown, a method for realizing quick opening of a disc player, the steps are as follows:

[0025] (1) In the standby state of the disc player, the operator presses the relevant buttons on the remote control or the panel control pa...

Abstract

The invention discloses a method for realizing rapid disc-opening of a disc player. The disc-opening or disc-closing operations are carried out when a master control system is initialized. The method is realized by means of a rapid disc-opening circuit which comprises a master control system, a slave control system, a disc loading device and a control unit. The master control system is connected with the disc loading device through an SATA, the slave control system is communicated with the master control system through an RS233 serial port and is connected with the disc loading device througha control bus. The master control system completes the decoding and output of audio and video signals. The master control system has the functions of power supply management, remote signal receiving process and key detection. The disc loading device comprises a disc loading rack, a disc loading tray, a laser head for reading discs and a servo disc-reading control system, thus realizing disc loading and disc data reading. The invention saves times, and effectively realizes human-computer interaction at the same time.

Description

technical field [0001] The invention relates to a fast opening circuit, in particular to a circuit for realizing fast opening of a disc player. Background technique: [0002] At present, the disc player circuit on the market generally consists of a master control system, a slave control system, a disc loading device and other control units. The disc loading device is generally connected to the main control system through SATA (full name is Serial Advanced Technology Attachment, a serial hardware drive interface based on industry standards) or other signal buses. The main control system has functions such as codec and format conversion output of audio and video signals, user operation interface display and user operation response. Therefore, the entire software system of the main control system is relatively complicated, and the initialization process is relatively slow, especially for some embedded Linux, Windows Mobile, and Android systems, it generally takes more than ten...
