The 2226 is a USB 2.0 A/V (Video & Audio) capture device. The 2226 supports multiple video input formats including 1080i, 720p, 480i, & 576i. The 2226 outputs MPEG2-TS with H.264 High Profile MPEG encoding for HD and H.264 Main Profile for SD. It is capable of decoding the encoded 2226 H.264 stream back to the HD & SD SDI outputs as well as the composite SD outputs. HD video is encoded in H.264/AVC High Profile Level 4.0 while SD video is encoded in H.264/AVC Main Profile Level 3.0. A/V Multiplexing The 2226 performs synchronization of the audio/video streams in hardware. The resulting H.264 stream is perfectly synchronized with no noticeable lip flap or delay between the video and audio. Inputs The 2226 video inputs/outputs include HD/SD SDI, Composite video, and S-Video. The 2226 supports stereo/mono line in/out, XLR3 microphone input, and headphone output. Scaling and cropping The 2226, implements a completely arbitrary video scaler. By programming the source and destination widths and heights, the scaler will scale up or scale down the source video size to the destination video size defined by the user. Some examples include the following: When the input was standard definition, the scalers were set to scale each frame as follows: DVI scaler - scale 720x240 to 1280x1024 (or to 720x480 or 720x576) MPEG scaler - scale 720x240 to 720x240 When the input was high definition, the scalers were set to scale each frame as follows: DVI scaler - scale 1920x540 to 1280x1024 (or to 720x480 or 720x576) MPEG scaler - scale 1920x540 to 720x240 The 2226's firmware allows the user to arbitrarily crop the input image horizontally, and scale the result to the new output resolution. Example: Crop 100 pixels from the left edge of the image and 50 pixels from the right edge. Scale new 570x240 image to 1280x1024. Uncompressed Capture The 2226 is capable of outputting an uncompressed video stream through the USB port of the host pc. This reduces the visual latency and the load on the host CPU when displaying video. HD video streams are downscaled to comply with the bandwidth limitations of the USB 2.0 bus. Video Overlay The 2226 supports full screen HD image/logo overlay at 16 bit color. The 2226 allows up to 8 hardware managed overlapping images, or an unlimited number of user defined full screen bitmaps to be added to the video stream. The video with overlay is compressed for storage on the host PC, as well as passed through to the video outputs of the 2226.
