I want to output 2 HDMI input 4k30p using ADV8005.

Category: Software
Product Number: ADV8005

Hi,teams

I want to output 2 HDMI input 4k30p using ADV8005.

The environment is as follows
HDMI Input(3840x2160p30)
HDMI output(3840x2160p30) x 2

The register settings are as shown in the text below.
The RX and TX cores are connected.

When set as shown, different frequency clocks are output and the waveform of the data lane is also constant. (Is this a test waveform?).

I have confirmed that the ADV8005 is able to recognize the input InfoFrame at this setting.

Are there any other necessary settings?

We have confirmed that the ADV8005 works with 720x480p60 and 1920x1080p60 input/output with almost the same settings except for TX_STERM_DISABLE and registers other than those related to InfoFrame.


Best regards.

  • Hi,

      Could you please ensure with below register when you try to output with 4K30,

          

          

    Thanks,

    Poornima

  • Hi Poornima.

    Thanks for the reply.

    I tried adding the following configurations you gave me, but the output did not change.

    0xE828 0x12

    0xE610 0x40

    Have I made a configuration that I should not have done?

    I am able to display FullHD, but is there a dedicated configuration for 4K?

    Are there any other configurations I should be doing?

    Best regards.

  • Hi,

      Please let us know, Why you are enabling the VIM and VOM in different scalers and why don't you enable the particular scalar like PVSP or SVSP ?

      Also let us know your Receiver side part (Input feeding Rx Part) and Check whether your Rx is capable to receive 4K input .

      We do not have plain scripts for the ADV8005 So kindly check with our source code to find out a specific / dedicated register for 4K - There is a click through SLA to get the source code for the ADV8005 eval board.
     You can get the source code project for the EVAL-ADV8005-SMZ here  Advantiv EVAL-ADV8005-SMZ Video Evaluation Board 

    Thanks,

  • Hi, 

    Thanks for the reply.

    This is the output waveform when the taught registers (0xE828,0xE610) are configured.

    The result seems to be the same as before adding configuration.

    After the waveform is output, the waveform continues to be output even when the power of the video source is turned off, which leads us to believe that the ADV8005 is outputting the waveform on its own.

    >>Why you are enabling the VIM and VOM in different scalers and why don't you enable the particular scalar like PVSP or SVSP ?

    Sorry, could you please tell me which part you are talking about?

    I am using Bypass (Mode 9) (UG-707/P.36), so I am aware that PVSP and SVSP are not enabled, am I wrong?

    >>Also let us know your Receiver side part (Input feeding Rx Part) and Check whether your Rx is capable to receive 4K input .

    I just want to input 4K30p on the ADV8005 Serial Video Receiver and put out 4K30p from HDMI TX1/2 with Bypass (Mode 9).
    Sorry, can you please tell me what you mean by this question?

    Best regards.

  • Hi,

     1. I am using Bypass (Mode 9) (UG-707/P.36), so I am aware that PVSP and SVSP are not enabled, am I wrong ?

         YES you are right, In Bypass mode the input Video would straight away pass into the output port without any Video processing So PVSP/SVSP signal processing does not come into the part (PVSP/SVSP registers are does not seems to be effective if we are in bypass mode ).

         In Bypass mode, Below register confirmation is enough.

              

    2. I just want to input 4K30p on the ADV8005 Serial Video Receiver and put out 4K30p from HDMI TX1/2 with Bypass (Mode 9).

    Sorry, can you please tell me what you mean by this question?   

       This i meant like, How you are feeding your input to Serial Vided Receiver, For example whether from any other chipset (Note that Serial video receiver can accept the output of an HDMI transmitter such as the ADV7511, ADV7623 or ADV7850 ).

      As i stated, We do not have scripts for the ADV8005 So kindly check with our source code to find out a specific / dedicated register for 4K Since we don't face any issue in our EVAL 8005 board.

    Thanks,

    Is our understanding correct that settings to the PVSP register (0xE8xx,0xE9xx), SVSP register (0xE6xx), Encoder register (0xE4xx) and DPLL register (0xE0xx) are not necessary?

    Also, is our understanding correct that the bypass mode (model 9) also supports 4K30p resolution?

    >>This i meant like, How you are feeding your input to Serial Vided Receiver, For example whether from any other chipset (Note that Serial video receiver can accept the output of an HDMI transmitter such as the ADV7511, ADV7623 or ADV7850 ).

    The signal from the HDMI source is input directly to the ADV8005.

    The input/output of 1080p60Hz resolution is successful, so I think the board design is correct.

    >>As i stated, We do not have scripts for the ADV8005 So kindly check with our source code to find out a specific / dedicated register for 4K Since we don't face any issue in our EVAL 8005 board.

    Which is the source file?

    Also, have you confirmed 4K30P operation with RX and TX bypass?

    Best regards.

  • Hi,

      Let me confirm and let you know about the bypass mode 4K30P support in "EVAL ADV8005 board" .

    Thanks,

    Poornima

  • Hi,

     

    Thanks  for your reply and that you confirm this on the evaluation board.

    When will I know the results?

     

    Best regards.

  • Hi,

      Here we can able to play the 4KP30 (VIC 95) in bypass mode. Please find the below attached debug log for your reference.

      Also i have attached the ADV8005 default register configuration settings and could you please open the same in AVES blue tool or any register configuration tool.
