Volume data, and it is sent to memory；
The determining Transcoding Scheme specifically: controller is first by media formats to be transcoded and itself transcoding capabilities collection
Match, further itself transcoding capabilities collection is matched with low performance media device decoding capability collection then, determines Transcoding Scheme, preferentially
Hardware transcoding is selected, the format that hardware transcoding is not supported selects software transcoding.
Step 308: controller sends the transcoding message comprising Transcoding Scheme to converter, and converter treats transcoding media number
It is sent to memory according to progress real-time transcoding, and by media data after transcoding, executes step 310；
Converter described here treats transcoding media data and carries out real-time transcoding, specifically: the first sub-processor parsing packet
Transcoding request containing Transcoding Scheme, obtains Transcoding Scheme；Decoder is treated transcoding media data and is decoded, and source media number is obtained
According to, and source media data is sent to encoder；Encoder recompiles source media data, obtains media number after transcoding
According to, and in memory by media data storage after transcoding.
Step 309: controller transmission does not support transcoding message to give low performance media device, executes step 311 later.
Step 310: media data gives low performance media device after scheduling of resource processor uploads transcoding, and executes step
311。
Step 311: terminating this process flow.
