DIGITAL BROADCAST TRANSMISSION DEVICE AND DIGITAL BROADCAST RECEPTION DEVICE

摘要

A digital broadcast transmission device generates channel connection information as information for correlating a plurality of physical channels. A bit stream containing program-associated information having the channel connection information is divided into a plurality of bit streams which are transmitted by the respective physical channels. According to the channel connection information, the digital broadcast reception device selects a plurality of physical channels by using a plurality of front end units and demodulates the broadcast waves received by the respective physical channels. The bit streams demodulated are connected and outputted. Moreover, a light-weight bit stream having a smaller information amount than the aforementioned bit stream is transmitted in parallel by a different single physical channel.
