Abstract

A digital broadcasting reception terminal and a digital broadcasting data processing method using the same can reduce the overhead increase of the operation system as well as the use of resources. The digital broadcasting reception terminal includes a digital broadcasting receiver for receiving digital broadcasting data; a demodulator for demodulating the received digital broadcasting data and outputting a reporting signal when the digital broadcasting data have been demodulated up to a preset capacity, wherein the reporting signal reports demodulation of the digital broadcasting data up to the preset capacity; and a control unit for reading and outputting the demodulated digital broadcasting data when the reporting signal has been output from the demodulator.

Claims

1. A digital broadcasting reception terminal comprising:

a digital broadcasting receiver for receiving digital broadcasting data;

a demodulator for demodulating the received digital broadcasting data and outputting a reporting signal when the digital broadcasting data have been demodulated up to a preset capacity, wherein the reporting signal reports demodulation of the digital broadcasting data up to the preset capacity; and

a control unit for reading and outputting the demodulated digital broadcasting data when the reporting signal has been output from the demodulator.

2. The digital broadcasting reception terminal as claimed in claim 1, wherein the control unit includes a ring buffer for storing the digital broadcasting data read from the demodulator.

3. The digital broadcasting reception terminal as claimed in claim 2, wherein the larger the preset capacity of the ring buffer, the larger the capacity of the demodulated digital broadcasting data.

4. The digital broadcasting reception terminal as claimed in claim 1, wherein the control unit reads the demodulated digital broadcasting data after a predetermined period, for a case where the demodulator fails to output the reporting signal in spite of the existence of demodulated data.

5. A method for processing digital broadcasting data by a digital broadcasting reception terminal, the method comprising the steps of:

receiving and demodulating digital broadcasting data;

reading and storing the demodulated digital broadcasting data when the digital broadcasting data have been demodulated up to a preset capacity; and

outputting the stored digital broadcasting data.

6. The method as claimed in claim 5, wherein in the step of reading and storing the demodulated digital broadcasting data, the demodulated digital broadcasting data are read and stored when a reporting signal, which reports demodulation of the digital broadcasting data up to the preset capacity, is output.

7. The method as claimed in claim 6, wherein in the step of reading and storing the demodulated digital broadcasting data, the demodulated digital broadcasting data are read and stored, for a case where the reporting signal fails to be output in spite of the existence of demodulated data.
