Abstract

A first HTML document for displaying a web page is received. In addition, the transport media stream which contains a predetermined number of transport media and a second HTML document as the presentation control information of the transport media is received. A DOM tree of the first HTML document is generated. When a video element that references the transport media stream is present in the first HTML document, the DOM tree that is generated according to the second HTML document contained in the transport media stream is linked beneath a node of the video element.

1 . A reception device, comprising:
 a first reception unit which receives a first HTML document for displaying a web page;   a second reception unit which receives a transport media stream containing a predetermined number of transport media and a second HTML document as presentation control information of the transport media; and   a DOM tree generation unit which generates a DOM tree of the first HTML document that is received by the first reception unit,   wherein, when a video element that references the transport media stream is present in the first HTML document, the DOM tree generation unit links the DOM tree that is generated according to the second HTML document contained in the transport media stream beneath a node of the video element.   
     
     
         2 . The reception device according to  claim 1 , further comprising:
 an element acquisition unit which acquires a predetermined element of the second HTML document based on the DOM tree that is generated by the DOM tree generation unit.   
     
     
         3 . The reception device according to  claim 2 , further comprising:
 a display control unit which controls display of the web page based on the DOM tree that is generated by the DOM tree generation unit,   wherein the display control unit displays information relating to presentation control of the predetermined number of transport media on a display screen of the web page based on the predetermined element of the second HTML document that is acquired by the element acquisition unit.   
     
     
         4 . The reception device according to  claim 2 ,
 wherein a program for accessing a specific element of the second HTML document is contained in the first HTML document, and   wherein the element acquisition unit acquires the specific element of the second HTML document based on the program.   
     
     
         5 . The reception device according to  claim 2 ,
 wherein reference information for acquiring a program for accessing a specific element of the second HTML document is contained in the first HTML document, and   wherein the element acquisition unit acquires the specific element of the second HTML document based on the program that is acquired using the reference information.   
     
     
         6 . The reception device according to  claim 1 ,
 wherein the transport media stream is a transport stream in which first transport packets containing a payload of the transport media, and second transport packets containing information relating to the transport media are time division multiplexed.   
     
     
         7 . The reception device according to  claim 6 ,
 wherein the transport packets are MMT packets, and   wherein the second HTML document is an MMT-CI.   
     
     
         8 . An information processing method in a reception device including a first reception unit which receives a first HTML document for displaying a web page; and a second reception unit which receives a transport media stream containing a predetermined number of transport media and a second HTML document as presentation control information of the transport media, the method comprising:
 a step of generating a DOM tree of the first HTML document that is received by the first reception unit; and   a step of linking the DOM tree that is generated according to the second HTML document contained in the transport media stream beneath a node of a video element when the video element that references the transport media stream is present in the first HTML document.   
     
     
         9 . An information processing device, comprising:
 a data acquisition unit which acquires a first HTML document for displaying a web page; and   a DOM tree generation unit which parses the first HTML document that is acquired by the data acquisition unit and generates a DOM tree in which a plurality of elements are associated with each other,   wherein, when a video element that references a transport media stream containing a predetermined number of transport media and a second HTML document as presentation control information of the transport media is present in the first HTML document, the DOM tree generation unit links the DOM tree that is generated according to the second HTML document contained in the transport media stream beneath the video element.
