Abstract

Disclosed is a technique for realizing efficient transmission of a plurality of contents under the condition that a minimum required QoS is ensured. According to the technique, two or more contents are set as main content, and the remaining content is set as fallback content. In addition, one of the two or more main contents is set as the broadcast content to be actually broadcast, and the remaining main contents are set as conversion contents. The data transmission device transmits the two main contents to the data receiving device through a high-quality line (main content line), and transmits the remaining backup content to the data receiving device through a low-quality line (proxy data transmission line) whose quality is lower than that of the main content line. Data receiving device. In addition, the conversion of the content is carried out by switching between the content for broadcasting and the content for conversion, and switching between the content for conversion and the content for backup.

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 (broadcasting 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 using Microwave's FPU (Field Pickup Unit; Field Pickup Unit) capable of rebroadcast transmission performs wireless transmission, and transmits 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 between the mob...
