Summary:To provide a broadcast receiver capable of executing a function of higher added-value.SOLUTION: A broadcast receiver includes a receiving part for receiving a digital broadcast signal including a first dataflow, a communication unit 121 for acquiring a second dataflow mapped to the first dataflow from a server device via a communication line, a video decoding section 141 capable of generating decoded video data by decoding the video data included in the first dataflow and/or the video data included in the second dataflow, and a digital interface 40125 capable of outputting video to an external apparatus, and capable of acquiring performance information of the external apparatus. The video output control state by the digital interface has an output control state for outputting only the decoded video of the image data of the first dataflow, and a second output control state for outputting the video data of the first and second data flow, according to the performance information of the external apparatus.SELECTED DRAWING: Figure 29A 【課題】より付加価値の高い機能を実行可能な放送受信装置を提供する。【解決手段】第一のデータフローを含むデジタル放送信号を受信する受信部と、通信回線を介してサーバ装置から、第一のデータフローと対応付けられた第二のデータフローを取得する通信部121と、第一のデータフローに含まれる映像データ及び/又は第二のデータフローに含まれる映像データを復号して復号映像データを生成可能な映像復号部141と、外部機器へ映像を出力可能であり、外部機器の性能情報を取得可能なデジタルインタフェース40125と、を備える。デジタルインタフェースによる映像出力制御状態には、外部機器の性能情報に応じて、第一のデータフローの映像データの復号映像のみを出力する出力制御状態と、第一のデータフローの映像データと第二のデータフローの映像データの両者を出力する第二の出力制御状態とを有する。【選択図】図29A
