The present invention relates to providing remaining battery information of a battery in a portable broadcast receiver, and more particularly, to an apparatus and method for providing remaining battery information of a portable broadcasting receiver for reprocessing and providing battery remaining information according to broadcast program information.

Recently, due to the advent of digital multimedia broadcasting (DMB), portable broadcast receivers such as a portable multimedia player (PMP) are widely used.

DMB is divided into satellite DMB and terrestrial DMB according to the signal transmission method. In Korea, satellite DMB is set as pay broadcasting and terrestrial DMB is set as free broadcasting, and the spread of portable broadcast receivers capable of receiving terrestrial DMB is accelerating. It is becoming.

Terrestrial DMB can be defined as a kind of digital TV service that can receive clear picture quality on the go through the ultra-high frequency band currently used for analog TV broadcasting.

The terrestrial DMB standard is basically based on the European Digital Audio Broadcasting (DAB) standard. The standard is also called EUREKA-147, after the relevant project in the EU, and was finalized in the mid-1990s. The EUREKA-147 standard is organized around the MPEG-1 audio layer II standard (also known as the MUSICAM method) to enable data services closely related to audio and data services in a separate stream or packet form. Multiple audio compression streams and various kinds of data are each channel-coded and then multiplexed into a single bitstream together with system control data. This multiplexed result is called an ensemble. Is sent via Although operating modes are defined for several frequency bands, in Korea terrestrial DMB, one ensemble uses a transmission mode with a VHF bandwidth of 1.5 MHz.

In addition, DMB has different characteristics from the existing broadcasting in that multi-function data broadcasting is possible. While traditional broadcasting is a service centered on voice and video, DMB has a feature that data service is possible with it. The data service plays a role of complementing the existing video and voice-oriented broadcasting service. In consideration of the characteristics of the data service as a communication service, the DMB has an interactive function and some attributes of communication.
