Hallo all,
somebody know what standar the hvx200 use to stram out the dvcprohd on the ieee1394?

I immagine is maby the IEC-61883-3 (HD-VCR Data Transmission)
or the IEC-61883-5 (SDL-DVCR Data Transmission)
some body can confirm this???

thx

P


PS:
IEC-61883-4: MPEG2-TS Data Transmission is for HDV
IEC-61883-2: SD-VCR Data Transmission is for standard DV

PS 2 add: i found this info

  • "IEC 61883-1: General" defines a common isochronous packet format, a functional control protocol, data flow management, and connection management procedures for audio/visual data.
  • "IEC 61883-2: SD-DVCR" describes the specifications for the data transmission of standard definition digital video television systems.
  • "IEC 61883-3: HD-DVCR" describes the specifications for the data transmission of high definition digital video television systems.
  • "IEC 61883-4: MPEG2-TS" describes the specifications for the data transmission of the MPEG-2 transport stream.
  • "IEC 61883-5: SDL-DVCR" describes the specifications for the data transmission of high compression mode digital videocassette recorder systems.
  • "IEC 61883-6 (PAS): Audio and Music Data Transmission" defines the specifications for the transmission of common digital audio formats and MIDI data.

after a all afteroon search on the net i think ieee1394 stream for dvcproHD use a modified version of IEC 61883-2 standard like normal DV stream.
The main differnce is the DIF PacketSize in CIP block is 1920bytes (compare to 480 bytes for DV - logic because dvcprohd is 4 time "biger" than DV 100mbs compare to 25mps seconds)
I found some header information of DVCpro signal mode and mode mask on Darwin source code from Apple on the IOFireWireAVC and IOFWDVComponents.
If some experts can confirm my conclusion can be very nice ;)

thx
