Product Description
Designed on a small board, the T4MPEG-4 module performs real-time hardware compression of audio and video with network streaming capability. The heart of the module is a Toshiba T4 compression and decompression LSI which operates in full compliance with the MPEG-4 standard. The module contains all essential functions for implementation of data streaming over networks. Also incorporated, an SD memory card interface which allows recording of streaming audio and video and playback over the network. Streaming data resident in SD memory can be downloaded over the network as well. What's more, a skip back storage function for 'killer-application' monitoring is also provided. Consequently, the module contains rich functions and is largely self-contained reducing need for external circuits, but can also be easily expanded for additional functions.
Essential Features
• Skip back storage enabling event-raised timed video and audio recording on
SD memory card for recording of selected scenes.
• Variable bit-rate for video delivery at low data rates.
• Streaming playback according to the RTP standard.
• Built-in web server function allows remote control of the module
• Video and audio data in ASF format can be saved in SD memory card.
• Easy control via RS232C command interface

Product DescriptionThe CB4100, is a miniature camera board that piggybacks a T4MPEG-4 module. It can be interfaced with network-camera systems and a variety of video equipment. Resembling the size of a PC card, it features an MPEG-4 compressor and decompressor LSI, an SD card socket, and a LAN connector. CB4100 is designed to record video from a camera in SD memory card with small data amounts (compliant with the SD-video standard) and to distribute images in real-time over a network. Moreover, CB4100 adds a web server function eliminating need for a dedicated display when the video is replayed. Videos can be enjoyed with a PC web browser, by which access to video data in the inserted SD memory card allows addition and erasure of video files.
Essential Features
• Network capability allows function control using a web browser.
• Automatic recording and e-mail notifications triggered by signals from external sensors.
• Automatic e-mail notification of events and their raise time.
• Recording on SD card in ASF format.
• Event triggered storage on SD card (by external sensors, etc.).
• Recording and saving of video from 20 seconds prior to any triggered event.
• Built-in RTC, time code superimposed on input video.
• Delivery of real-time video thanks to IP network control function.
• PC client viewer allows simultaneous connection of up to four displays.
• Pan and tilt motor control of connected camera.
• Mode switch, LED and multi-purpose board for event I/O.
