Embodiment 1

[0029] figure 2It is the working principle diagram of this audio and video on demand computer. In this illustration, such an audio and video on demand method will be explained: after the audio and video on demand computer is turned on, the CPU main module (2) transfers the BIOS and hard disk (3) of the main board (1) ), the operating system file instruction in the graphics card (7) drives the display (8) to enter the operating system, and the CPU main module (2) calls the main thread module instruction in the memory (4) again, and drives the display (8) through the graphics card (7) 8) Expand the man-machine dialogue interface (9) to enter the on-demand waiting state. The user uses the input device (10), sends a request instruction to the main thread module in the memory via the signal communication module through the man-machine dialogue interface (9), and the main thread module, with the cooperation of the CPU main module, manages the module, information through the applica...

Embodiment 2

[0031] image 3 It is a schematic flowchart of the realization of high-definition effects on this computer. In this illustration, such a method for realizing high-definition effects will be explained: through the main thread module, playback module, decoding management module, playback control management module, and database management module in the memory. With the cooperation of memory (4), CPU main module (2), program resource library in hard disk (3), and audio and video decompression card (5), through a series of cooperative actions between program modules and hardware, high-definition image quality The image and sound effects of surround sound quality are displayed and played on the TV and stereo. This method can integrate, play control, manage and serve any existing or future upgraded audio and video decompression card under the MPEG (Moving Picture Experts Group) standard or other standard organizations, and can decode and control the existing MPEG standard All video ...

Embodiment 3

[0033] This audio and video on-demand computer can realize the function of workstation / server all-in-one, Figure 4 It is the working principle diagram of using this audio and video on-demand computer to connect to the local area network. Figure 5 It is a schematic diagram of building a local area network with this audio and video on-demand computer. After the computer is turned on, the CPU main module (2) searches for the network card (6) to establish network connections with other audio and video on-demand computers in the network through the switch, and enters the network communication and interactive service state. The computer schedules and processes resource request instructions through the main thread module with the cooperation of the memory (4) and the CPU main module (2). command to obtain the resource service provided by the same audio and video on demand computer in other places; when the foreign place sends a resource request command to the local through the loc...

Abstract

The invention relates to a computer and a method for playing audio and video files on demand, specifically to a computer and a method capable of independently playing audio and video files on demand, belonging to the field of computers. The computer for playing the audio and video files on demand comprises a main board, a main CPU (central processing unit) module, a hard disk, an unzipping card for the audio and video files, a display card, a display, an input device and a network card; the computer is characterized in that the audio and video files can be independently played on demand, and a storage with a program package is arranged on the main board of the computer for playing the audio and video files on demand. The invention provides an on-demand playing method for managing the work of a single computer, and a user can play the audio and video files on demand through a human-computer interface. The computer and the method for playing audio and video files on demand have the following beneficial effects: the single computer for playing the audio and video files on demand can be moved and placed conveniently, and can be used in any occasion; the computer can be used online, so that the problem that the whole or part of the system cannot be used due to the collapse of a local area network or the damage of a server is solved; and with the program package for centralized control in the storage, multiple independent on-demand playing, service and management functions for the audio and video files can be realized.

Description

technical field [0001] The invention relates to a computer and method for audio and video on demand, in particular to a computer and method capable of independently performing audio and video on demand. belongs to the computer field. Background technique [0002] At present, a kind of known audio and video program on-demand computer adopts the workstation broadcast-server centralized control method; another kind adopts the set-top box on-demand-server centralized control method. Worksite broadcasting—server centralized control method is composed of workstation broadcasting system (on-demand computer, on-demand software and DVD decompression card), network transmission computer (network card, crystal head, network cable, switch), server centralized control system (video server, central broadcasting Control system software, audio and video program resource library server, resource management server), TV and audio and other playback equipment are connected in series. Operate ...
