Abstract
Method for controlling a memory in a digital system, including the steps of (a) dividing the memory into a plurality of fixed sized memory blocks, (b) defining at least one of the memory blocks as a compression/decompression region, (c) assigning compression priorities to rest of the memory blocks except the memory blocks defined as the compression/decompression region, and (d) making the memory blocks to deal with an external data received according to an external command, and carrying out compression/decompression of data required in the dealing with the external data at the compression/decompression region according to the compression priorities.
Claims15
A method for controlling a memory in a digital system, comprising the steps of:
- (a) dividing the memory into a plurality of fixed sized memory blocks;
- (b) defining at least one of the memory blocks as a compression/decompression region;
- (c) assigning compression priorities to rest of the memory blocks except the memory blocks defined as the compression/decompression region;
- and,
- (d) making the memory blocks to deal with an external data received according to an external command, and carrying out compression/decompression of data required in the dealing with the external data at the compression/decompression region according to the compression priorities.
A digital TV receiver comprising:
- a tuner for receiving a digital broadcasting signal;
- a TP (transport) signal analyzer for analyzing a TP signal from the digital broadcasting signal, to detect an audio signal and a video signal;
- a decoder for separating and decoding the audio signal and the video signal analyzed at the TP analyzer;
- an A/V decoder for decoding the audio signal and the video signal decoded in the decoder;
- and,
- a microcomputer including;
- a storage managing module for storing all the data from the tuner in forms of data blocks by indexing or hashing, and carrying out a function to find a desired block from the stored data blocks quickly,
- a request processing module for facilitating storage of a desired data in a memory, or erasing or finding the desired data from the memory,
- a synchronism control module for processing various requests on the same time, and
- a memory managing module for managing the memory with the memory divided into same sized blocks,
- the memory for storing channel, program, and information data received through the tuner into fixed sized blocks, with the channel, program, and information data divided;
- an OSD (On Screen Display) processor for processing an OSD text;
- and,
- a display for selectively superimposing, and displaying an A/V signal decoded at the A/V decoder and the OSD text from the OSD processor.
