Summary: | To provide a technique for more preferably transmitting or receiving an advanced digital broadcasting service.SOLUTION: A digital broadcast receiver includes a first receiving unit that receives a digital broadcasting broadcast wave in which a 2K broadcast program and an extended broadcast program transmitted by modulated waves of different layers of the same broadcast wave are transmitted by simultaneous broadcasting from a broadcasting station, and a second receiving unit that receives the broadcast wave of the digital broadcast. In the broadcast wave, a 2K broadcast service that transmits the 2K broadcast program is transmitted by a modulated wave in an upper layer of the broadcast wave, and a 2K broadcast service that transmits the extended broadcast program is transmitted by the modulated wave of the lower layer of the broadcast wave.SELECTED DRAWING: Figure 2A
【課題】高度デジタル放送サービスをより好適に送信または受信する技術を提供する。【解決手段】同一の放送波の異なる階層の変調波で伝送される2K放送番組と拡張放送番組とが、放送局側からサイマル放送で伝送されるデジタル放送の放送波を受信する第1の受信部と、前記デジタル放送の前記放送波を受信する第2の受信部とを備え、前記放送波において、前記2K放送番組を伝送する2K放送サービスは、前記放送波の上側階層の変調波で伝送され、前記拡張放送番組を伝送する2K放送サービスは、前記放送波の下側階層の変調波で伝送される、デジタル放送受信装置、を用いる。【選択図】図2A |
