AM3517 for HDMI video streaming

Other Parts Discussed in Thread: AM3517

Hi,

I want to use the AM3517 for a video streaming application. I have to play a high resolution video 1920x1080 25Hz on a standard 1080p60 full HD TV monitor.

I have already a board based on a AM3517... so I want to use it for this scope. Is it possible in your opinion?

thanks for your help

    Unfortunately this may be a bit above and beyond what the AM3517 is capable of for two reasons.

    Firstly would be codec performance, the AM3517 has no DSP or accelerator for video codecs so decoding a 1080p@25fps stream would be difficult to be done entirely on the Cortex-A8 core alone.

    The second problem would be getting a 1080p60fps stream output, the maximum pixel clock on the display is around 74.25MHz which gives just enough for 1080i60 or 720p60 video rates, so to drive a display at 1080p60 would require external frame rate doubling hardware.

    As an alternative for 1080p@25fps video decoding you may want to consider the DM6467, it has more limited GPP and graphics capabilities, but it can deal with higher rate video encode/decode applications.
