4 1: Introduction The microh264-d4 is a 4-channel H.264 (MPEG-4 Part 10 AVC) codec on a single mini PCI module. The microh264-d4 provides a low power and high performance solution for capturing and compressing up to 4 concurrent video inputs to H.264 standard. The microh264-d4 not only provides H.264 compression but can also decompress and playback recordings from storage to display. Utilizing the 32-bit PCI architecture, the microh264-d4 allows high quality real-time video and audio capture and compression from (up to) 4 concurrent NTSC or PAL video sources to disk while at the same time providing an additional path for incoming video to be previewed on the host screen. The board also provides a text/graphics overlay and motion detection on all four channels. AMP can provide custom configurations (subject to a minimum order quantity) for the microh264-d4. Please contact our Sales team (see A: Contacting Advanced Micro Peripherals, page 21) to discuss your requirements. 4

8 1 1: Introduction microh264-d4 Hardware Reference Manual Functional summary Signal sources Video digitization The microh264-d4 is designed to capture and record from up to four separate and unrelated video sources simultaneously. Each of the four video input channels of the microh264-d4 features a video frame grabber and an audio digitizer. Each frame grabber contains a digital NTSC/PAL video and each video channel has an associated audio input. A single audio input is associated with each live video channel. Composite NTSC or PAL video is input to the microh264-d4 through the U.FL miniature coax connector, CX1, CX2, CX3 and CX4. The video is AC-coupled and fed to the on-board decoders of the individual frame grabbers. The video decoders automatically detect whether the incoming video signal is NTSC or PAL and generate the correct timing output signals. Each video channel is first decoded to chrominance and luminance signals and then digitized by high speed analog-to-digital (A2D) converters. The A2Ds output are passed to the H.264 encoder. 8

9 1 1: Introduction microh264-d4 Hardware Reference Manual Real time live video H.264 encoding Digital video data streams from the 4 Frame Stores are routed to the hardware H.264 encoder engine where the video can be compressed. Each of the video channels can be compressed to a separate H.264 stream, resulting in four separate H.264 streams which can be written to disk (or LAN) as separate files. These streams can be up to full size at full frame rate. The encoding engine continuously encodes the video streams and uses its PCI bus Master/Initiator interface to transfer data across the bus to the system memory or disk. Note: The encoding path only supports a simple text overlay capability. Video Preview The microh264-d4 provides a secondary video path allowing the recorded video to be streamed to the graphics controller buffer of the host system for video previewing. The Preview output can also be used to view an alternate video source while recording other inputs. The Preview information is also available as a composite NTSC/PAL output suitable for driving a NTSC/PAL or RS-170 display device. Note: The VGA preview output does not include an overlay capability, however, the composite analog output does offer support for full color, bit mapped graphics overlay with alpha-blending. Real time H.264 video decoding / playback The microh264-d4 can receive H.264 encoded video data over the PC/104-Plus bus and decode it to a raw digital video stream. This is fed into a high speed digital-to-analog converter and then encoded to analog composite video as either NTSC or PAL. Additionally, the raw digital video stream can be displayed on the system VGA using the real time video preview functionality. Maximum image size of decoded video is 704x480 (NTSC) or 704x576 for PAL. Audio data which is part of the original recording is also decoded and played back in synchronization with the video. In addition to playback to the system display VGA device, the microh264-d4 also provides a composite NTSC/PAL playback output suitable for directly driving a PAL/NTSC or RS170 display device. OSD Video Text/Graphics Overlay The microh264-d4 has two supported modes for OSD overlay; A simple (single color) text overlay may be added to the recording path for the video data. In addition to this, a full color bit-mapped graphics overlay feature is available for the analog preview output. This offers a choice of 64k colors (16 bit) 9

10 1 1: Introduction microh264-d4 Hardware Reference Manual and the ability to use up to 64 levels of alpha-blending between the graphics data and input video source. Note: There is no overlay functionality for the host VGA controller preview path. Motion Detection and Event Triggers The microh264-d4 supports automatic motion detection on a per channel basis. The sensitivity of the motion detection can be set independently per channel. Each channel supports 330 (NTSC) or 396 (PAL) detection blocks. Using the motion-detection feature, the microh264-d4 can be operated in a baby-sitting mode where recording is committed to disk only when scene motion event is detected, to make most efficient use of disk storage. Software for the microh264-d4 allows recording of pre-trigger, on-trigger and post-trigger events. 10

17 2 2: Installation microh264-d4 Hardware Reference Manual microh264-d4 card installation Software for the microh264-d4 is provided on a CD-ROM. The video input cable should be plugged into CX1 and a suitable live video source connected. If you are using a recent BIOS version and operating system, the microh264-d4 should be detected automatically. Software driver installation should be done from the supplied CD-ROM. Further instructions (and demo programs) pertinent to particular operating systems are provided on the driver CD-ROM. 17

18 3: Recording options Multi-channel recording modes The microh264-d4 can perform recording of up to four channels at full resolution during multi-channel recording at a configurable frame rates. There is the option to record only video or both video and audio. Video from the four frame grabber channels A, B, C and D is recorded as 4 separate and individual streams. In this mode, encoding parameters can be set for each channel on a per-channel basis allowing different settings for each of the channels. Each channel may be recorded with or without audio. Frame rates The default frame rates are 29.97fps and 25fps for NTSC and PAL respectively. However, for increased flexibility, additional fractional frame rates are supported. Please see the software reference manual for further details. 18

19 3 3: Recording options microh264-d4 Hardware Reference Manual Frame type encoding The microh264-d4 supports two frame encoding schemes within the H.264 requirements to provide flexibility and optimize encoding efficiency and storage space. The default is I/P encoding, where both I and P frames are involved in the encoding. An alternative is I-only encoding. With I/P encoding, the I interval, which is defined as the number of P-frames between I-frames can be set to any number between 1 and 255. Video Bit Rate control The Video Bit Rate can be set separately for each channel of compression (and hence storage efficiency) by using one of the three bit rate control schemes Variable Bit Rate (VBR), Constant Bit Rate (CBR) and Hybrid Bit Rate (HBR). With VBR, the Quantization value (default of 5) can be set between 1 and 31 to optimize efficiency for a particular application (with 1 being highest and 31 being lowest quality). This mode strives to keep the quality constant and will change the bit rate accordingly. The default bit rate for CBR is 1Mbit/sec. However, the actual bit rate may change by +/-10% around the set figure until the system settles down. CBR therefore does not guarantee that the bit rate in practice will be exactly as set the microh264-d4 simply does its best to achieve the set CBR figure. The real life bit rate when in CBR mode will depend on the incoming video, motion and other environmental factors. With HBR, the microh264-d4 is given an upper and lower bit rate limit and will attempt to avoid abrupt changes in bit rate by changing the picture quality gradually only when the bit rate limits are exceeded. It may be worth finding out experimentally the optimum CBR setting for a particular application environment in order to make the best use of CBR configuration. 19

20 3 3: Recording options microh264-d4 Hardware Reference Manual Hints for reducing bit rates There are four ways that you can reduce the bit rate and hence optimize storage: Reduce the picture size Increase the quantization value Reduce the frame rate Increase the I picture interval NOTE: THESE OPTIONS MIGHT NOT BE AVAILABLE UNDER CBR. IN CBR, QUANTIZATION VALUE IS CONTROLLED BY THE MICROH264-D4 TO MEET THE SET BIT RATE ONCE THE PICTURE SIZE, FRAME RATE AND I PICTURE INTERVAL ARE FIXED. 20
