Sensor: An image is formed on the sensor, and digital video data is sent to the Camera ISP
Camera ISP: Video processing functions such as BLC, AGC etc.
Video enhancer: Further additional video processing such as WDR, DNR, skin tone enhancement, 3D de-interlacing
Codec: Compress the video data into smaller file format and send to the network

The camera ISP is the heart of all video processing. Specially in high megapixel resolutions, the ISP is particularly important in determining the frame rates, video processing at various lighting conditions and ability to process wide FOV pictures such as video wrapping & cropping.

16. Video cropping with independent streaming
Video cropping is used for indoor application – shopping store => 1 camera replacing 4 cameras
For scenery that is close, it is effective. For scenery that is far, the object appears to be smaller and hence not so effective under cropping

17. Electronic PTZ Beneficial with Wide FOV/High megapixel cameras:
Do digital pan, tilt, zoom without moving mechanical parts
Wide FOV + ePTZ => A large field of view is constantly present, but for example when MD in one regions happens the view can auto ePTZ to the MD region, while the other camera view is still being monitored and recorded

18. FAQ Why is optical zoom only available up to 3MP? Ans:
3 A’s are the key to good video: Auto white balance, Auto focus & Auto exposure. All three A’s require frame to frame comparison for video algorithm to take place. Having 30fps for video image processing is a key factor.
When >3MP, the frame rate is reduced and therefore the amount of data required for video processing will not be enough, or time taken will be too long to achieve a good picture that meets the 3 A’s.
For higher megapixel cameras beyond 3MP, the pixel count is high enough so digital zoom is considered instead.
ACTi is not chasing a multi megapixel resolution only, rather ACTi is focusing to adopt full camera technologies in addition to just higher resolution.
3A – AWB, AF, Auto exposure. Eg. For auto focus, it is comparing two frames so the reduction of frames means that this focus will take time to happen. Achieving 30fps is a major gain to all advanced video processing

19. FAQ Why is Day & Night only available up to 3MP?
Ans: Under such a large picture, the ability to do D&N correctly is a challenge. Focus shift, noise levels at night mode vary within the larger picture.
Another reason is because peripheral components such as lens, IR cut filter etc will need to be able to support >3MP resolutions as well, and there is a technical barrier. Of course if these barriers at the peripheral components can be resolved, then ACTi will adopt D&N into >3MP cameras.
Why is WDR/DNR only available up to 2MP?
Ans: The main reason is because the video data beyond 2MP is too much for the ISP processing engine to handle calculations intended for WDR & DNR. Another reason is the reduced frame rates at >2MP means that the frame to frame comparison is not highly efficient.
Why is ePTZ only available at 5/10MP?
Ans: This is because the FOV is wide enough to allow significant space/movement for ePTZ.
Why is video cropping with 4 streams only available at 5/10MP?
Ans: This is because the overall picture size is large enough to allow significant use of video cropping at 4 different regions within this picture. If the picture size is small, then transmitting the entire picture rather than 4 separate pictures makes more sense.

Primarily for entry level applications with limited computing resources, this profile is used in videoconferencing and mobile applications.
Main profile
Originally intended as the mainstream consumer profile for broadcast and storage applications, the importance of this profile faded when the High profile was developed

The primary profile for broadcast and disc storage applications, particularly for high-definition television/video

SoC
SoC (System on Chip) has dedicated performance for IP camera applications
- ACTi adoption
- To achieve multi megapixel, the algorithms are highly complicated so a dedicated processor with full computing power is necessary
DSP (Digital signal processor) are based for multi purpose applications, not necessarily for IP surveillance
- H.264 baseline profile at most
Key performance differentiators:
Maintaining good video quality under compression
Able to achieve high frame rates at high megapixel resolution
Network streaming with low latency and jitter
Overall firmware stability in varied working environments

22. Codec & Camera ISP integration?
Sensor
Codec
Video
enhancer
The camera ISP is in charge of video processing, while Codec for video compression
- They are doing completely different functions, putting them into one chip may limit overall performance and stability
Each technology to be developed separately
- Separate development will allow greater technology improvement in their specific fields
- ACTi is following a separate development trend until both technologies are mature
Possible challenges:
System cost of two separate chips is higher Eg. External memory
Increase of risk – video signal from ISP to Codec is exposed on PCB level, not internal. At higher resolutions with high frame rates, the video signals being exposed (rather than being internal of a chip) are highly sensitive and could cause integration issue

23. FAQ Why type of H.264 compression is ACTi using and why?
Ans: ACTi is adopting baseline for initial product phase with VGA ~ 2.0MP, and will move to high profile (skip main profile) for second phase from 2.0MP ~ 10.0MP. High profile includes more intelligent encoding with added features, so it means that less information decoding (as compared to baseline) is required by the NVR system, hence less CPU resources are required by the NVR server.
Can ACTi achieve multiple streaming?
Ans: Yes, dual streaming can be achieved at all video resolutions. For example, it can be two H.264 streams, or one H.264 stream + one MJPEG stream.
At 5/10MP cameras, up to 4 independent video streams can be outputted from 4 different regions within the picture.
