Abstract

Disclosed is a technique for effectively transmitting a plurality of contents under circumstances where a minimum required QoS has been ensured. According to this technique, with respect to a plurality of contents to be transmitted to a data reception device, two or more contents are set as main contents, and the remaining contents are set as standby contents. One of the two or more main contents is set as broadcasting content which is actually broadcasted, and the remaining main content is set as switching content. The data transmission device transmits the two main contents to the data reception device through a high-quality line (a main content line), and transmits the remaining standby contents to the data reception device through a low-quality line (a proxy data transmission line) of lower quality than the main content line. Content is switched through a change between the broadcasting content and the switching content and through a change between the switching content and the standby content.

Description

technical field [0001] The invention relates to a data transmission technology for transmitting content, in particular to a data transmission device and a data transmission control device in a content transmission system for transmitting multiple contents. Background technique [0002] Currently, in the case of relaying broadcasts from broadcasting destinations (rebroadcasting sites), etc., the video / audio data captured / collected at the broadcasting site is passed through SNG (Satellite News Gathering; Satellite News Gathering) using communication satellites, Or use the FPU (Field Pickup Unit; Field Pickup Unit) capable of rebroadcasting transmission of microwaves to perform wireless transmission, and transmit the video material / sound material for broadcasting to the broadcasting station. In broadcasting using communication satellites or FPUs, generally, a mobile broadcasting station called an broadcasting vehicle is installed at the broadcasting site, and the transmission b...
