IP Camera
From Texas Instruments Embedded Processors Wiki
Contents |
Overview
Texas Instruments offers multiple highly optimized reference designs based on the TMS320DM3xx DaVinci™ video processors for the IP camera market to enable developers to speed through the design process as well as reducing overall bill of materials costs. These refrence designs are owned by Texas Instruments and managed with third parties.
Hardware block diagram of the IP Camera is given below:
These reference designs:
- Reduce development time by 98 percent
- Deliver higher quality, wider fieldof-view HD images
- Decrease electronic bill of materials
- Empower customers to bring U.S $150 HD IP cameras to the market
These solutions reduce development to under four months by including:
- Complete and optimized schematics
- Gerber files
- Free Linux application source code including:
- Integrated auto white balance and auto exposure
- Simple motion detection
- Dual-stream HD H.264, MPEG-4 and MJPEG video codecs to support recording and monitoring needs at full frame rates
- DaVinci IP camera software framework including I/O application programming interfaces (APIs), media APIs and DaVinci Codec Engine
Software architecture block diagram for IP Camera reference design is given below.

PSIA Compliance
The Physical Security Interoperability Alliance (PSIA) was founded with the objective of promoting the interoperability of IP enabled security devices. PSIA has published ‘IP Media Device Specifications’ which specifies an interface that enables video management systems to communicate with various IP media devices in a standardized way. Refer PSIA webpage for more details at http://www.psialliance.org/index.html
IPMD Conformance tool is available from PSIA to validate the conformance of an IP security device. All conformant products are listed in the PSIA website at http://www.psialliance.org/ConformantProductsList.html
DM36x IPNC camera v2.0 release has implementation of IP Media Device API Specification, Version 1.1, Revision 1. Conformance report for this is available at the PSIA website in the conformant products link mentioned above.
Video showing the usage of PSIA conformance tool is at PSIA website.
IP Camera Reference Design Vs DVSDK
Digital Video Software Development Kit (DVSDK) is a software development kit provided by TI which can be used for developing multimedia applications. It provides all the components required in developing multimedia applications and provides some demo applications. DVSDK runs on the DVEVM and is part of the software supplied with the EVM.
IP Camera Reference Design is an application developed to address IP Camera market. It has all the components which are optimized for use in the IP Camera application. IP Camera software runs on the BOM and form-factor optimized hardware specific for the IP Camera. IP Camera software is developed based on the DVSDK software components.
The table below summarizes the key differences between IP Camera and DVSDK application with respect to a IP Camera product.
| Features / Components | IP Camera Reference Design | DVSDK / DVEVM |
|---|---|---|
| Codecs, Framework Components, Codec Engine | Yes | Yes |
| Linux kernel, drivers | Yes | Yes |
| Network stack (TCP/IP, RTP/RTSP, FTP, SMTP) for IP Camera application | Full | Partial |
| BOM Optimized and Form factor ready hardware | Yes | No |
| IP Camera application | Yes | No |
| Advanced IP Camera features (Video Stabilization, Video Noise Filter) | Yes | No |
| Basic Video Analytics (Face detection/recognition, Motion detection) | Yes | Partial (Face detection) |
| Advanced Video Analytics | Supported with VA card plugin | No |
| Auto Exposure and Auto White-balance | Yes | No |
| Lens distortion / shading correction | Yes | No |
| Image Tuning support | Yes | No |
