TDA3MV: design parameter

Hi Raymond,

Please find answers to your question below.

Raymond He said:

1. Does it support 1080P 60fps 4-camera input or 720P 60fps 4-camera input?

but over which interface? Over MIPI, we can capture 1080p 4CH @30fps. The frame rate 60 would be difficult, almost impossible, depending on the pixel size..

Raymond He said:

2. support  video output 1080P 60FPS？

Yes, it does support 1080p 60fps output.

Raymond He said:

3. Does it support  3D viewing and transparent chassis display？

There is no GPU on TDA3x. You could probably use LDC to generate 3D view..

Raymond He said:

4. Does the system delay requirement of 60ms satisfy? This means sensor to serializer to deserializer to TDA3, and finally to TFT with a total system delay

Well, it really depends usecase, so difficult to tell without understanding usecase.

Raymond He said:

5.What's the TDA3 delay? Refers to the video from the chip CSI input to LVDS output delay

Did not get the question, do you mean delay in the current usecase? I would suggest to refer to datasheet to get the numbers..

Raymond He said:

6.Support for RTSP streaming media output？

Well, Ethernet is supported. You would require to port RTSP streaming support.

Raymond He said:

7.Does the DSP kernel run RTOS, BIOS or something else?

Yes, DSP runs on TI RTOS ie BIOS.

Raymond He said:

8. Is the AVM algorithm from third party or TI  reference?

TI provides reference algorithmm.

Hi brijesh

 More detials need your help to offer advices：

1. Does it support 1920x720p 4CH@60fps?

2. Does it  support 540 degree transparent chassis display ?

3. Does it  support video encoding output via Ethernet?

4. Show as below 360 3d look around case , 1080p 4CH@30fps input ，MIPI Input ----》 TDA3 chip internal video image processing and splicing process to complete -----》 Bt. 1120 OUT, how much is the transmit  delay？

thanks in advance

Hi Raymond,

Raymond He said:

1. Does it support 1920x720p 4CH@60fps?

Yes, capture can be supported for this resolution over MIPI, but cannot be processed in ISP. 

Raymond He said:

2. Does it  support 540 degree transparent chassis display ?

Well, this can be done in the SW features. I really doubt there is any HW feature that can support it. 

Raymond He said:

3. Does it  support video encoding output via Ethernet?

Yes, ethernet is supported.

Do you mean the latency here from the capture to display? 

I would say

- one frame time period in capture

- ISP and Dewarp processing depends on the frame size and can take around one frame time period

- not sure about dsp processing time, depends on the kind of algorithm you are running on it

- one frame time period in display.
