Abstract
A signal transmitting method comprising: inserting a context identifier and a keyword in service data to generate a content; extracting the service data from the content; inserting a description including the context identifier and the keyword to generate media data; generating signaling information including the context identifier and the keyword; and transmitting a signal including the media data and the signaling information.
Claims14
A signal transmission method comprising:
- generating content by inserting a context identifier and a keyword in service data;
- extracting the service data from the content and generating media data by inserting a description including the context identifier and the keyword;
- generating signaling information including the context identifier and the keyword;
- and
- transmitting a signal containing the media data and the signaling information.
2 more elements
A signal transmission apparatus comprising:
- a first generator configured to generate content by inserting a context identifier and a keyword in service data;
- a second generator (a file generator (3220)) configured to extract the service data from the content and generate media data by inserting a description including the context identifier and the keyword;
- a third generator (manifest (30230)) configured to generate signaling information including the context identifier and the keyword;
- and
- a transmitter configured to transmit a signal containing the media data and the signaling information.
2 more elements
A signal reception method comprising:
- receiving a signal containing media data and signaling information, wherein the media data comprises service data and contains a description containing context identification information and keyword information about the service data, and the signaling information comprises the context identification information and the keyword information;
- receiving a user request for the service data from a user and performing a control operation of extracting a keyword from a context contained in the user request;
- acquiring media data related to the keyword based on the keyword for the user request and the context identification information and keyword information included in the signaling information;
- parsing data related to the user request based on the context identification information and keyword information in the description contained in the media data;
- and
- decoding the data related to the user request.
3 more elements
