hm, Camera solutions are important target market for DM8148 family. DM8148 includes the key capabilities you are looking for including ability to capture 3MP/5MP as well as HDMI and USB 2.0 output. We will be announcing more details on DM8148 development kit over the next several months. DM8148 includes a GPU while the DM8147 does not. Jeremiah Golston, Texas Instruments

JG, Thanks for elaboration. I also visited TI and watched your 5 minutes video. However, there is large market for single channel - One HD CMOS sensor interface - 3MP/5MP or better and HDMI/ USB 2.0 outputs. I also tried your other development kit from Leopard Imaging. Howeve, it lacks HDMI output. Will you soon bring single channel solution with HDMI/USB output? Or is TM8148 is solution to it? I see development kit for DM8168, do you have one for DM8148? Will you please also explain difference between DM8147 adn DM8148?

Great questions. ASIC basic solutions are very different from this TI solution. The support for many channels of video capture and multiple displays are a good example of the additional capabilities. On the capture side, both DM8148 and DM8168 include multiple BT1120/BT656 digital video capture ports. These can support up to 16 channels of concurrent SD capture working in conjunction with TI's TVP5158 multichannel video decoder or multiple channels of 1080p60 capture. This is used in security Digital Video Recorders to enable multi-channel encoding from existing analog CCTV camera infrastructure. The multiple display outputs are useful in a wide variety of applications. In security DVRs, it can be used to output two sets of concurrent full HD video mosiac displays with 32+ channels of standard definition video without having to downscale too much for the limitations of only 1 HD display screen resolution. In video conferencing, it is useful to output to two parallel HD displays: one for the participants in the video call and one for shared presentations. DM8168 and DM8148 both have an integrated HDMI transmitter. Additional display outputs are supported using BT1120 digital video output ports that can output 1080p60 video to an additional HD screen. DM8168 and DM8148 both also support SD composite output and DM8168 includes HD component output as well using integrated video DACs. Hope this helps in providing some examples of the potential applications for multiple concurrent HD display outputs. Jeremiah Golston, Texas Instruments

I have a basic question. If input to this media processor is one CCD/CMOS image sensor, why does it need three outputs at 1080P60fps? Also, one output is on HDMI, wherer to do you send other outputs? Can HDMI take more then one outputs? I wish it had USB 3.0 support for 1080P60fps output. Will DB8148 will also have HDMI output built into this? I prefer Ambrella ASIC implementation to this TI solution.

Your points are well taken, selinz. I have not seen other media processors capable of three HD video streams (1080p@60), though. If anyone else out there has any info, let us know! But again, the point of this TI's announcement is that its new DaVinci media processor is NOT using its DSP core for video processing at all. Instead, they have integrated three units of well-crafted HD video accelerators inside DaVinci.

Sounds impressive but it would be interesting to have a comparison with other video processing DSPs.
