Abstract
Embodiments of an apparatus and a method for storing data in a digital broadcasting receiver can convert received digital TV broadcasting data into data of another format before being stored. In one embodiment, redundancy data of the digital TV broadcasting data can be generated based on the converted data of the predetermined format and stored with the converted data of the predetermined format to variably output two formats of data with the single stored data.
Claims19
A method for storing received first broadcasting data in a digital broadcasting receiver, the method comprising:
- converting the received first broadcasting data into second data of a predetermined format different from a format of the first broadcasting data;
- generating third data of the first broadcasting data based on the converted second data of the predetermined format;
- storing the third data with the converted second data of the predetermined format;
- and
- reading the stored second data of the predetermined format and the third data, performing a decoding combination for the read data;
- and outputting the combined data with the first broadcasting data.
A method for storing received digital broadcasting data in a digital broadcasting receiver, the method comprising:
- converting the received digital broadcasting data into data of a predetermined format different from a format of the digital broadcasting data;
- and
- generating redundancy data of the digital broadcasting data based on the converted data of the predetermined format and storing the redundancy data together with the converted data of the predetermined format, wherein, in case of an image, the redundancy data include data obtained by coding difference data between an image estimated from a frame of the converted data of the predetermined format and an image of a corresponding frame of digital broadcasting data.
A method for storing received digital broadcasting data in a digital broadcasting receiver, the method comprising:
- converting the received digital broadcasting data into data of a predetermined format different from a format of the digital broadcasting data;
- and
- generating redundancy data of the digital broadcasting data based on the converted data of the predetermined format and storing the redundancy data together with the converted data of the predetermined format, the method further comprising:
- reading the stored data of the predetermined format and the redundancy data, performing a decoding combination for the read data, and outputting the combined data with picture quality and speech quality of the digital broadcasting data.
A digital broadcasting receiver, comprising:
- a receiver configured to receive the digital broadcasting data;
- a converter coupled to the receiver and configured to convert the received digital broadcasting data into data of a reduced quality digital multimedia broadcasting (DMB) format for a mobile terminal different from a format of the digital broadcasting data;
- a storage device coupled to the converter configured to store the converted data;
- and
- a controller configured to control the converted data of the predetermined format to be stored in the storage unit, wherein, in case of an image, the redundancy data include data obtained by coding difference data between an image estimated from a frame of the converted data of the DMB format and an image of a corresponding frame of the digital broadcasting data.
