Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] figure 1It is a schematic flowchart of a multimedia decoding method according to an embodiment of the present invention. Such as figure 1 , the multimedia decoding method of this embodiment includes the following steps:

[0063] Step 101, the multimedia decoding device obtains the network transmission multimedia code stream;

[0064] Step 102, the multimedia decoding device converts the acquired network transmission multimedia code stream into an original basic code stream;

[0065] Step 103, the multimedia decoding device decodes the original elementary code stream.

[0066] In this example, preferably, the above-mentioned network-transmitted multimedia code stream is transmitted to the multimedia decoding device in the form of network p...

Abstract

The invention provides multimedia decoding method and device as well as video monitoring method and system. The decoding method comprises the following steps of: A, obtaining network transmission multimedia code stream by a multimedia decoding device; B, converting the obtained network transmission multimedia code stream into original basic code stream by the multimedia decoding device; and C, decoding the original basic code stream by the multimedia decoding device. By using the multimedia decoding method, code stream adaptive decoding with a plurality of formats can be realized, and because only ES stream is decoded, the complexity of processing of a decoding module such as a decoding chip is effectively decreased, and the decoding performance of the decoding module is improved.

Description

technical field [0001] The invention relates to the processing of network transmission multimedia code streams, in particular to a multimedia decoding method and device, and a video monitoring method and system. Background technique [0002] With the rapid development of information networking, network-based digital monitoring technology has gradually expanded its application fields due to its technical advantages such as flexible networking, convenient management and ultra-long-distance transmission, and has a tendency to replace traditional monitoring. The continuous development of monitoring technology towards network and digitization has accelerated the wide application of multimedia technology in the monitoring industry. Multimedia includes text, sound, images, graphics, etc., and has the characteristics of large amount of information and strong expressive ability. Therefore, it has become an irresistible trend to replace a single information mode. [0003] Driven by m...
