Abstract
Provided are a method for recording service data and a digital TV complex machine using the same. The method includes: determining whether to include OSD data as an additional data for guiding broadcasting contents to a user or providing a convenient manipulation of the digital TV complex machine to the user while recording service data; when the OSD data is not included, determining a service type of the digital TV service; extracting and outputting data designated by the determined service type; and recording the outputted data.
Claims19
A method for recording service data of a digital TV complex machine depending on service types of service data, the digital TV complex machine including a digital TV module and a recording/playing module, the method comprising:
- determining whether On-Screen Display(OSD) data is to be included in the service data to record, wherein the OSD data is additional data mixed with the service data for guiding broadcasting contents to a user or providing a convenient manipulation of the digital TV complex machine to the user;
- determining a service type of the digital TV service, when the OSD data is not included;
- extracting and outputting data designated based on the determination;
- and
- recording the outputted data.
A digital TV complex machine comprising:
- a digital TV module for outputting On-Screen Display(OSD) data that is additional data and outputting service data including audio/video signals, wherein the OSD data is mixed with the service data and is for guiding broadcasting contents to a user or providing a convenient manipulation of the digital TV complex machine to the user;
- a recording/playing module for recording/playing the service data and the OSD data outputted from the digital TV module;
- a data output control module for selectively extracting signals output from the digital TV module;
- and
- a central control unit connected to and controlling operations of the digital TV module, the recording/playing module and the data output control module and configured to:
- determine whether OSD data is to be included in the service data to record;
- determining a service type of the digital TV service, when the OSD data is not included;
- extract and output data designated based on the determination;
- and
- record the outputted data.
