Figure 5 Model decoder in receiver showed with data processing flow

The decoding process in receiver can be divided in the following steps:

a) data broadcasting decoding process: mono-media such as character figure, still pictures, videos, audio, are transmitted in data stream or object and data carousel. These data are decoded and divided so that they are individually processed as coded mono-media;

b) mono-media decoding process: coded mono-media data is decoded by an appropriate decoder. Generally, video and audio are decoded by exclusive hardware decoder, but it may be optionally made by software for interactive applications use such as still picture, mpeg2-I frame;

c) execution and presentation process: mono-media shall be presented in video, still pictures, text and graphic and subtitles planes.
