Definitions

  • FIG. 2 is a diagram illustrating an example of a protocol stack indicating protocols used in the information processing apparatus 1. Note that descriptions of parts that are not related to the present invention are omitted.
  • the TS demax unit 11 separates TS packets according to the media type (S8). Specifically, in the case of an audio stream, the audio stream separated from the TS packet is output to the audio decoder 40. Similarly, in the case of a video stream, the video stream separated from the TS packet is output to the video decoder 50.
  • FIG. 10 is a diagram for explaining an example of referring to a hint using descriptor ().
  • the MMT_descriptor () described in (a) of the figure includes information (signaling_message_hint_present_flag) indicating the presence / absence of a hint related to transmission of control information (signaling message).
  • signaling_message_hint_present_flag When the value of signaling_message_hint_present_flag is “1”, the data structure signaling_message_hint () shown in FIG.
  • FIG. 11 is a block diagram illustrating a main configuration of the information processing apparatus 300. Since the configuration other than the demax unit 310 is the same as that of the information processing apparatus 1, illustrations other than the demax unit 310 and the surrounding configuration are omitted.
  • the Service B is composed of control information b1 and package b2.
  • the package b2 includes an MMT stream b21 including an asset b211, an asset b212, and control information b213, and the MMT stream a22.
  • the MMT stream a22 is an MMT stream that is referenced from both the package a2 and the package b2.
  • information (session information) necessary for receiving the MMT stream b21 and the MMT stream a22 is described in a predetermined format.
  • the control information b213 describes the above-described MPT (MMT Package Table).
  • the MPT describes the package identifier of the package.
  • Session identifier b21 Main sub flag: 1 Number of referenced packages: 1 Package identifier: b2 Session description: SDP description in FIG. 19A (however, the multicast group address or port is different from the description in FIG. 19A) Session identifier: a22 Main sub flag: 0 Number of referenced packages: 2 Package identifier: b2 Package identifier: a2 Session description: Description by SDP in FIG.
  • the user selects (switches) a service (S20).
  • the session is terminated (S21).
  • the additional stream is acquired from the acquisition destination indicated by the acquisition destination information in the network different from the multiplexed stream separated by the first separation means.
  • the additional stream and the second multiplexed stream separated by the first separation means are reproduced so that the additional stream is reproduced instead of the second multiplexed stream separated by the first separation means or together with the second multiplexed stream. Perform separation. Therefore, streams acquired from different networks can be combined and reproduced.
