Media transmission method and system between high and low density networks

Abstract

The embodiment of the invention discloses a media transmission method and system between high and low density networks. The method comprises the following steps: a low density network center obtains amedia push request; the low density network center controls a media push module to push to-be-pushed media data and media association information indicated in a low density network media push requestto a high density network under the control of a security isolator; and the high density network receives the media data and the media association information sent by the security isolator, and controls to play or stop playing the media data according to a media playing control instruction initiated by a user through the media association information. By adoption of the technical scheme of the embodiment of the invention, the limitation of media stream transmission between the high and low density networks can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to network data transmission technology, and in particular to a method and system for media transmission between high-density and low-density networks. Background technique [0002] High-density network (Height Secret Network, HSN) and low-density network (Low Secret Network, LSN) have many application scenarios in the existing technology, such as IPTV network and Internet, internal monitoring network and external network, etc. A high-density network is a network with a higher level of security, while a low-density network is a network with a relatively lower level of security and more openness. [0003] In view of the difference in the level of network security, the data transmission between the high-density network and the low-density network is not equal. In the prior art, the high-density network can only passively accept data information sent from the low-density network, while the high-density netw...

Problems solved by technology

The disadvantage of this technical solution is that the high and low density networks are connected by audio and video lines, and there is a certain transmission risk; due to the limitation of the number of audio and video lines for transmission, the number of codecs is fixed. The number of video transmissions needs to increase the encoder equipment and the corresponding number of decoder equipment
