Nucleus Name
DS_DVIO_Routing
Nucleus Number
704
Description
Route a DV stream containing an audio and video signal through the physical
and link layer ICs to the Codec. This test works for both NTSC and PAL.
Technical
-
Initialise the DMA to transfer 5 frames PAL/NTSC
-
Initialise the DV de-multiplexer
-
Initialise the 1394 interface and start reception of the DV stream
-
Check whether the stream was copied to memory properly by the byte
input interface (port to memory type DMA)
Execution Time
6-10 seconds (6 when OK, 10 when no stream or error)
User Input
None
Error
Number
Description
70400
Routing the signals succeeded
70401
The 1394 link chip could not be initialised properly
70402
There was a syntax error in the DV stream
70403
DMA could not copy DV stream to memory. Stream connected?
70404
DMA not working properly
