Description

本発明は、放送システムに関する。 The present invention relates to a broadcasting system .

Claims (1)

放送システムであって、A broadcasting system,
放送伝送路にＭＭＴデータを送出する送出装置と、A sending device for sending MMT data to a broadcast transmission path;
放送伝送路で伝送された前記ＭＭＴデータを受信可能な受信装置とを備え、A receiving device capable of receiving the MMT data transmitted through a broadcast transmission path,
前記受信装置は、The receiving device is:
放送伝送路で伝送されたＭＭＴデータを受信する受信部と、A receiving unit for receiving MMT data transmitted through a broadcast transmission path;
前記ＭＭＴデータに含まれる番組コンテンツの映像をデコードする映像デコーダと、A video decoder for decoding video of program content included in the MMT data;
前記映像デコーダでデコードされた映像を表示する表示部とを有し、A display unit for displaying the video decoded by the video decoder;
前記送出装置は、前記ＭＭＴデータで送出する同一の前記番組コンテンツについての、映像信号の標準ダイナミックレンジ特性とハイダイナミックレンジ特性を識別する情報として、ＭＭＴデータのＭＭＴ−ＳＩに含まれる第１の識別情報と、前記番組コンテンツの映像信号の符号化映像ストリーム内の第２の識別情報と、を前記ＭＭＴデータにより送出可能であり、The transmission device includes a first identification included in the MMT-SI of the MMT data as information for identifying a standard dynamic range characteristic and a high dynamic range characteristic of the video signal for the same program content transmitted by the MMT data. Information and second identification information in the encoded video stream of the video signal of the program content can be transmitted by the MMT data,
前記受信装置は、前記番組コンテンツの映像信号の標準ダイナミックレンジ特性とハイダイナミックレンジ特性との切り替わりを、前記第２の識別情報ではなく前記第１の識別情報により識別することにより、前記番組コンテンツの映像信号の符号化映像ストリーム内の前記第２の識別情報を参照するより早く前記切り替わりを識別するものであり、The receiving device identifies switching of the standard dynamic range characteristic and the high dynamic range characteristic of the video signal of the program content not by the second identification information but by the first identification information. Identifying the switch earlier than referring to the second identification information in the encoded video stream of the video signal;
前記受信装置は、前記第２の識別情報により、前記番組コンテンツの映像信号が標準ダイナミックレンジ特性であるかハイダイナミックレンジ特性であるかを識別するのみならず、ハイダイナミックレンジ特性の映像信号に施されているガンマ補正の種類も識別する、The receiving device not only identifies whether the video signal of the program content has a standard dynamic range characteristic or a high dynamic range characteristic based on the second identification information, but also applies it to a video signal having a high dynamic range characteristic. Identify the type of gamma correction being performed,
放送システム。Broadcast system.
