MPEG4000ULP Ultra Low Power MPEG-4 Codec for PC/104- P l u s The MPEG4000ULP is an ultra low power 4-channel MPEG-4 Codec on a single PC/104-Plus form factor. It equips power constrained systems with a high performance solution for capturing and compressing up to 4 concurrent analog video inputs to MPEG-4 standard. Records up to four concurrent PAL/NTSC channels The MPEG4000ULP utilizes 32-bit PCI architecture to perform high quality real-time video and audio capture and compression from up to 4 concurrent PAL or NTSC video sources to disk whilst at the same time allowing incoming video to be previewed on the host screen. Ultra low power In addition to providing MPEG-4 compression the consumption MPEG4000ULP can decompress and replay stored recordings, and text and graphic annotation can be alpha-blended with the incoming video. The high performance and reduced bus utilisation of the MPEG4000ULP allows up to four cards to be combined in a PC/104-Plus system to channel up to 16 concurrent video streams to disk or across a network. The MPEG4000ULP is supported by a suite of drivers for Windows, Linux and QNX.

There is no Split Video Stream separation and the resulting MPEG-4 file can subsequently be played back as single MPEG-4 In the Split Video Stream (SVS) mode the stream by the MPEG4000ULP or appropriate multiple channels being previewed are captured hardware/software decoders. and recorded as separate files or streams. The MPEG4000ULP will output four files - one per Video Setting channel. These streams are independent and can subsequently be played back as totally The MPEG4000ULP supports PAL and NTSC independent MPEG-4 streams by appropriate video input. The required standard is software hardware/software decoders or through the selectable. playback feature of the MPEG4000ULP. In applications where recording space is The SVS mode supports 2 sub modes: restricted the MPEG4000ULP provides additional  4 x CIF size MPEG-4 each at full frame rate; flexibility by supporting a range of capture 4  4 x D1 size MPEG-4 each at lower frame rate frame rates at or below the standard video When set for 4 x CIF, the 4 inputs can be rates (30/25fps NTSC/PAL). For NTSC, the concurrently recorded each at full frame rate. Frame Rate can be set to 30, 15, 7.5, 3.75, etc Each channel is first decimated to quarter down to 0.9375 fps. For PAL, the supported screen size prior to encoding. This results in frame rates include 25, 12.5, 6.25, etc down to sizes of 352x240 for NTSC and 352x288 for 0.7813 fps. The lower frames rates in each PAL. case are derived by successive division by 2. The 4 x D1 sub-mode allows 4 inputs to be I/P Frame Encoding recorded each at full D1 size with input at less The MPEG4000ULP supports encoding of both I than full frame rate. 4 full D1 size (up to and P frames.
