AM5728: Questions about VIP(Video Input Port)

Kenji Kawaguchi

Part Number: AM5728

Hello, experts

I'm considering to develop a H.264 Codec board with AM5728.
I have several questions about VIP(Video Input Port).

Q1. AM5728 has 3 VIPs(Slice:6). Discrete Sync can support maximum 6 video inputs simultaneously. Is that correct?
Also, can Port A and Port B of Slice be used simultaneously?

Q2. About Source Multiplexing (Refer to page 1916, AM572x SitaraTM Processors Silicon Revision 2.0,1,1 Technical Reference Manual）

According to Table 9-13 Multiplexing Configurations, input D1 Interlaced can be 8@(Maximum Channels in Single 16-bit Data Interface Mode)
That is to say, AM5728 can support Maximum 48(= 3VIP * 2Slice * 8) channels, right?

Q3. About the below Modes on Table 9-13 :
　　　(A)Maximum Channels in Single 16-bit Data Interface Mode

　　　(B)Maximum Channels in Dual 8-bit Data Interface Mode -Interleaved Channels per　Single 8-bit Port.
　　　 One 16-bit VIP can be　configured to support two such　8-bit ports.

If the input data format condition: BT.656(8bit YCbCr:4:2:2), are the connection configurations like the attatched(connection.pdf)?

Thank you in advance.connection.pdf

Hi Kenji,

Please find answers to you questions below,

1, Yes, port A and B can run simultaneously.

2, Well theoretically, yes, but these VIP pins are muxed with multiple modules, so possible only if pins are available.

3, i did not get your this question, you mean how many channels can be captured for 8bit BT656 interface?

Rgds,

Hello Brijesh,

Thank you for your answer.

Sorry, I still have some questions about your answer:

> 1, Yes, port A and B can run simultaneously.

If pins are available, Discrete Sync can support maximum "10"(not 6) video inputs simultaneously, right?
(Refer to page 1873, AM572x SitaraTM Processors Silicon Revision 2.0,1,1 Technical Reference Manual）

My question is how the circuit diagrams are. Are the circuit diagrams of the attachment(see connection_circuit_diagram.pdf) correct?

Hello Kenji,

Theoretically, yes, if the pins are available, it can support.

Yes, (A) will use 16bit input mode and (B) will use dual 8bit interface mode.
