Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The core idea of ​​the present invention is mainly to retain the incomplete frame data at the end of the previous data segment and merge it with the head of the next data segment during decoding and playing the multimedia data read or downloaded in segments, When it is judged that the combined data content is the same frame, the next data segment is decoded and played from the combined frame; otherwise, after the combined content is discarded, the remaining data in the next data segment is decoded and played.

[0036] The method for realizing segmentation decoding among the present invention comprises the following steps:

[0037] Step 1, decode the multimedia data in the segment buffer in units of frames, if the decoding of the cu...

Abstract

The invention discloses a multimedia playing method and a playing terminal, wherein the playing method comprises: multimedia data is read in a cache memory in segments, the multimedia data in the segmental cache memory is decoded in frames, and the decoded data is played; when decoding proceeds to the end of the current data segment, if the data block at the end is less than one frame, the data block is kept and combined with the header of the next data segment into a combined data block; and pre-analysis is performed to determine whether the combined data block is in a same frame, the combined data is decoded if yes, or discarded if not. The playing method and the playing terminal combine the end data less than one frame at the end of the prior segment with the header data of the next segment, thereby being capable of avoiding the risk of the direct discard of the end data block caused by the segment division, decreasing interrupted playing as possible, and improving the experience of customers.

Description

technical field [0001] The invention relates to a multimedia processing technology in an embedded device, in particular to a multimedia playing terminal and a playing method. Background technique [0002] In the current development of embedded systems, due to the limitation of equipment hardware conditions and the need for cost control, it may not be possible to use hardware codec to complete the support for multimedia audio and video playback, and it is necessary to implement soft decoding of multimedia data. The playback function, on the one hand, overcomes hardware limitations, and on the other hand, can save costs. [0003] For example, when an MP3 audio file is played on a multimedia player terminal (such as a mobile phone, MP3, MP4 player, TV mobile phone, GPS navigator, etc.), the MP3 audio data is usually first read from a local file on the terminal; The MP3 encoder supported by itself converts the MP3 audio data into an audio data format (such as PCM data) that can...
