放送伝送路および通信伝送路を介して伝送される放送番組のコンポーネントを含むＩＰデータフローを受信可能な放送受信装置で実行する一時蓄積の制御方法であって、A temporary storage control method executed by a broadcast receiving apparatus capable of receiving an IP data flow including components of a broadcast program transmitted via a broadcast transmission path and a communication transmission path,
前記放送伝送路では、前記ＩＰデータフローがＴＬＶストリームに格納されて伝送され、該放送伝送路のＴＬＶストリームは前記放送受信装置のチューナで受信されるものであり、In the broadcast transmission path, the IP data flow is stored and transmitted in a TLV stream, and the TLV stream of the broadcast transmission path is received by a tuner of the broadcast receiving apparatus,
前記通信伝送路では、前記ＩＰデータフローが、前記放送受信装置における前記チューナとは異なる通信部で受信されるものであり、In the communication transmission path, the IP data flow is received by a communication unit different from the tuner in the broadcast receiving device,
前記放送番組を構成するコンポーネントを示すＭＰＴと、前記放送伝送路および前記通信伝送路により伝送されるコンポーネントと、前記コンポーネントのデコードに用いる現在時刻であって協定世界時刻を示す第１の時刻情報と、前記第１の時刻情報とは異なる時刻情報であって１６ビットの数値データである日付データを含み現在時刻を示す第２の時刻情報と、を受信する受信ステップと、An MPT indicating a component constituting the broadcast program, a component transmitted by the broadcast transmission path and the communication transmission path, and first time information indicating a coordinated universal time which is a current time used for decoding the component; Receiving the second time information indicating the current time including date data which is time information different from the first time information and is 16-bit numerical data; and
前記受信ステップで受信した前記放送番組を一時蓄積する一時蓄積ステップと、A temporary storage step of temporarily storing the broadcast program received in the reception step;
を有し、Have
前記一時蓄積ステップで一時蓄積される前記放送番組のコンポーネントは、ＭＰＵ単位で前記第１の時刻情報のフォーマットと同一のフォーマットの時刻情報を含むタイムスタンプと対応づけられているものであり、The component of the broadcast program temporarily stored in the temporary storage step is associated with a time stamp including time information in the same format as the format of the first time information in units of MPU.
前記放送番組の一時蓄積に用いられる時刻管理処理は、前記第２の時刻情報を用いる時刻管理処理であり、前記時刻管理処理においては、所定の日付を用いた判定処理に応じて、前記第２の時刻情報の日付データの値に１０進法表記での６５５３６の値を加算する処理を行うか否かを切り替える、一時蓄積の制御方法。The time management process used for temporary storage of the broadcast program is a time management process using the second time information. In the time management process, the second time information is determined according to a determination process using a predetermined date. Temporary accumulation control method for switching whether or not to perform the process of adding the value of 65536 in decimal notation to the date data value of the time information.
