Fair of SEED: more high-definition, more intelligent! (1)

"Hot!" the security show for several years, this is all visitors of my tongue hung with words, and this year is no exception.

And most of the visitors who SEED product manager liurui used in all the major venues around a circle, capture some fresh design. He was delighted that a couple of years ago a lot of concept products have been applied to the product on a large scale. "Hi-def, NVR is no longer a trend of things. ”

More HDTV, more intelligent

DVS6467T solution based on DM6467 processor, up to do 10D1 coding, on-site presentation is the same with knitted 4D1, up a 1080p display on a TV

In the SEED stage, suddenly in front of a screen display of multiple images, according to the introduction, this is liurui SEED lot D1 decoding scheme SEED-DVS6467T, the programme is particularly suitable for 4/8-channel D1 standard definition DVR, and video server product development, and scalable multichannel intelligent analysis algorithms.

DVS6467T on h.264 encoding algorithm is optimized, resulting in 8-channel D1 encoding H.264 30fps, also increases the 8-channel Cif auxiliary code stream. In the algorithm, and also integrates the OSD, occlusion detection functions algorithm, while at the same time increases the Panel keys, transport communications program. As more suitable for the security industry application, DVS6467T is also equipped with a high efficiency ARM/DSP LINK software framework, reduces the ARM/DSP system footprint and called EDMA in occupies.

The programme includes hardware platforms and software development kits and hardware platforms in full accordance with DVR application design with 8 channels compound video input, 1 way composite video output, HD-component and two DVI output, SATA interface RS485/232 serial, USB, and other interfaces.

Software development include video capture, coding, network transmission, playback, display the full program, optimized program framework and encoding algorithm that greatly reduces the difficulty of DM6467 development.

On the basis of the DVS6467T SEED also developed 8-channel video encoder module SEED-DVSM6467, direct DVRs, DVS, etc, reduces the difficulty of development engineers, equipped with a standard Mini PCB interface, you can achieve through the host, and internal PCI boot directly integrates with 8 channels of D1 H.264 30fps + 8-ch Cif H.264 + OSD + occlusion detection.

In this fair, TI has also demonstrated for the first time series based on Netra DM8168 processor-high-definition video conferencing (1080P60 with knitted with solutions) and 16 Channel DVR solution (solution with knitted with 16D1).

And 1GHz clock DM6467T DM8168 compared to video compression can improve performance, while improving the multi-channel density, and can support a higher resolution. In addition, the SoC can significantly improve high-definition video pre-processing and post-processing functions, and thus a lower bitrate supports higher quality video, video security and video communication. Relative to the previous generation of digital video processors, support advanced video analysis and enhanced 2D and 3D graphics, innovative single-chip SoC to DM8168 video depends on the implementation of the 16 channel video formats such as H.264 DVR functionality, which can significantly reduce DVR system cost and complexity. "We have already started doing this, we focus next year," liurui introduction, after all, a solution based on DM6467 is already very mature, in order to provide a better proposal, SEED will be launched in 2010 DM8168 hardware platform based, 2011, and will continue to introduce software solution.

"Previous product Cif resolution, can only see the clothes color only," introduction, so traditional liurui Cif image sharpness, already far from being able to meet the needs of the present monitoring area, the D1 resolution will become the mainstream market, at the same time, to reduce storage pressure, MPEG4 H.264 also replaced become the mainstream market.

Single DVR device support for more video channels, a DVR road supported 16 videos are no longer uncommon. With the development of a network camera, DVR gradually turn hybrid DVR/NVR, called DVR on the capacity of the network support, the requirements for a DVR is not just a simple hard disk recorders, you also need to have some common intelligent video analysis algorithms, such as motion detection, detection, and so on more lines, while also have high-definition output interface, HDMI, DVI, etc.
