Problems solved by technology

These methods can be used to achieve a certain degree of fast coding, but the shortcomings of these methods are: due to the limitations of the platform, the computing resources are limited and expensive, and the practicability is not very good. In terms of speed and speed, it is not very good for real-time or even super real-time encoding

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] With reference to as shown in Figure 1, with MPEG2 audio and video file (DVD) as the audio and video source of input, realize encoding cluster as an embodiment through fully decomposing and fully compiling, a kind of dynamic configurable encoding cluster method based on network, comprises the steps:

[0026] 1) Designate the cluster server, analyze the network resources, and set up the cluster environment of the scattered machines; the "analyze the network resources, establish the cluster environment of the scattered machines" in this step 1) is carried out through the following steps:

[0027] (1) The cluster server searches the entire network, checks the CPU occupancy rate of each computer in the network, and generates a cluster queue of scattered machines according to the CPU occupancy rate;

[0028] (2) For computers whose CPU usage r...

Abstract

The method includes steps: (1) building cluster environment for scattering devices; (2) building configurable distributed encoding model; (3) building and locking cluster to be encoded, and based on the cluster to be encoded, dividing up audio and video sources, and building task processes; (4) building task links to all computers in cluster to be encoded respectively, and sending task flow and task instructions to build whole dispatching and controlling environment for cluster to be encoded, and to arrange and monitor all computer to implement appointed encoding task; (5) taking back encoded results, and after completing collection of the said encoded results, server connects results of divided encoded pieces in sequence based on frame number of first frame in divided pieces; then carrying out audio encoding and multiplexing operation to accomplish whole encoding procedure. Advantages are: simple and configurable platform, high level of resources utilization, quick encoding speed.

Description

technical field [0001] The invention relates to a fast coding method related to digital audio and video codec standards used in the field of information technology, in particular to a network-based dynamically configurable coding cluster. Background technique [0002] The digital audio and video codec standard is the common basic standard of the digital audio and video industry, and has huge industrial demand. In the next five to ten years, my country's (high-definition) digital TV industry, high-density optical disk industry, broadband multimedia application and third-generation mobile communication industry will develop rapidly on a large scale and become an important industry group that affects the national economy. The 2008 Beijing Olympic Games will be a milestone in high-definition television broadcasting and mobile multimedia applications. [0003] AVS (Audio Video coding Standard), the digital audio and video codec technology standard formulated by my country, repre...
