Problems solved by technology

When the current set-top box plays MP3, it generally reads the mp3 file according to the progress of the MP3 playback time and then directly decodes and plays it. Therefore, when the set-top box plays MP3, if the user performs other complicated operations at the same time, there will be slow response or the MP3 playback pauses, which cannot be very fast.

Embodiment Construction

[0037] Such as figure 1 Shown is a structural block diagram of the first embodiment of the MP3 playing system arranged on the set-top box in the present invention. Set-top box comprises set-top box CPU, communication interface, the first cache and the second cache etc. that are arranged in the set-top box, the MP3 playing system that is arranged on the set-top box of the present invention comprises MP3 data reading module 1, MP3 decompression module 2 and PCM data playing Module 3. Wherein, the MP3 data reading module 1 reads the mp3 compressed data from an external storage device through the communication interface of the set-top box, and writes the mp3 compressed data into the first buffer that is positioned at the set-top box; The MP3 decompression module 2 is used for from Read the mp3 compressed data in the first cache and decompress to form PCM data, and write the PCM data to the second cache located in the set-top box; PCM data playback module 3 is used to read PCM fro...

Abstract

The invention relates to a system for playing an MP3 arranged on a set top box, comprising an MP3 data reading module, an MP3 uncompressing module and a PCM (Pulse Code Modulation) data playing module, wherein the MP3 data reading module reads MP3 compressed data from an external storage device through a communication interface and writes the MP3 compressed data into a first cache located in the set top box; the MP3 uncompressing module reads the MP3 compressed data from the first cache, carries out uncompress on the read MP3 compressed data to form PCM data, and writes the PCM data into a second cache located in the set top box; and the PCM data playing module is used for reading the PCM data from the second cache to play a video. The invention also relates to control method for playing an MP3 arranged on a set top box. By using double buffering mechanisms, if the user simultaneously carries out other complex operations when the set top box plays the MP3, the phenomenon of slow response or MP3 playing pause can not occur.

Description

technical field [0001] The invention relates to the technical field of MP3, and more specifically, relates to an MP3 playing system and a control method arranged on a set-top box. Background technique [0002] At present, the main frequency of the CPU of the set-top box is low, and the processing speed is slow, and the memory of the set-top box is generally small. When the current set-top box plays MP3, it generally reads the mp3 file according to the progress of the MP3 playback time and then directly decodes and plays it. Therefore, when the set-top box plays MP3, if the user performs other complicated operations at the same time, there will be slow response or the MP3 playback pauses. Good to meet customer needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an MP3 playback system and control method placed on a set-top box for the above-mentioned defects of the prior art. [0004] One of the technical solu...
