Contents reception device and method, contents transmission device and method, program, and recording medium

Abstract

The present invention relates to a contents reception device and method, a contents transmission device and method, a program, and a recording medium, whereby a Push-type NRT service can be realized. “Ch. 4” is taken as a broadcasting channel for normal broadcasting, and “Ch. 5” and “Ch. 6” are taken as broadcasting channels for NRT. The broadcasting channel “Ch. 5” is multiplexed on logical channels “VC5-1”, “VC5-2”, and “VC5-3”. The logical channel “VC5-1” is assigned to a single Push-type NRT broadcasting service, and “VC5-2” is assigned to a Pull-type NRT broadcast. The logical channel “VC5-3” is assigned to another Push-type NRT broadcasting service. Three FLUTE sessions are provided to “VC5-2”.

         14 . A contents transmission device comprising:
 contents information obtaining means configured to obtain information relating to a content to be broadcasted with a transmission rate unsynchronized with a playback rate, from a broadcasting schedule created beforehand;   determining means configured to determine whether or not said content is a content of a Push-type service for receiving a content to be viewed and listened to regardless of a user request;   first control information generating means configured to describe, in the event that said content is a content of said Push-type service, information representing that said content is a content of said Push-type service, along with information relating to said content, in first control information generated as information relating to a content to be broadcasted by a predetermined logical channel;   second control information generating means configured to generate second control information describing information for determining each of said logical channels in a physical channel serving as a transmission path of a broadcast wave signal of a predetermined frequency band;   multiplexing means configured to multiplex said first control information and said second control information with the data of said content, and also to multiplex data to be broadcasted by a plurality of said logical channels as data to be broadcasted by a single physical channel; and   broadcast wave transmission means configured to modulate said multiplexed data to transmit as a broadcast wave.   
     
     
         15 . A contents transmission method comprising the steps of:
 obtaining information relating to a content to be broadcasted with a transmission rate unsynchronized with a playback rate, from a broadcasting schedule created beforehand;   determining whether or not said content is a content of a Push-type service for receiving a content to be viewed and listened to regardless of a user request;   describing, in the event that said content is a content of said Push-type service, information representing that said content is a content of said Push-type service, along with information relating to said content, in first control information generated as information relating to a content to be broadcasted by a predetermined logical channel;   generating second control information describing information for determining each of said logical channels in a physical channel serving as a transmission path of a broadcast wave signal of a predetermined frequency band;   multiplexing said first control information and said second control information with the data of said content, and also multiplexing data to be broadcasted by a plurality of said logical channels as data to be broadcasted by a single physical channel; and   modulating said multiplexed data to transmit as a broadcast wave.   
     
     
         16 . A program causing a computer to serve as a contents transmission device comprising:
 contents information obtaining means configured to obtain information relating to a content to be broadcasted with a transmission rate unsynchronized with a playback rate, from a broadcasting schedule created beforehand;   determining means configured to determine whether or not said content is a content of a Push-type service for receiving a content to be viewed and listened to regardless of a user request;   first control information generating means for describing, in the event that said content is a content of said Push-type service, information representing that said content is a content of said Push-type service, along with information relating to said content, in first control information generated as information relating to a content to be broadcasted by a predetermined logical channel;   second control information generating means configured to generate second control information describing information for determining each of said logical channels in a physical channel serving as a transmission path of a broadcast wave signal of a predetermined frequency band;   multiplexing means configured to multiplex said first control information and said second control information with the data of said content, and also to multiplex data to be broadcasted by a plurality of said logical channels as data to be broadcasted by a single physical channel; and   broadcast wave transmission means configured to modulate said multiplexed data to transmit as a broadcast wave.
