Renesas Electronics Corporation Advanced 4-Channel A/V Decoder, MUX and Display Processor TW2851-BB2-GR

The TW2851 is Techwells 5th generation 4-channel A/V decoder, multiplexer and display processor IC for security surveillance applications. The device has four built-in NTSC/PAL video decoders with high-performance adaptive 4H comb filters, noise reduction algorithm, independent and flexible video scalars for the display and record paths and 16x12 matrix motion/blind/night detectors. The device includes advanced record and display multiplexer functions. The record multiplexer supports multichannel frame-, field- and byte-interleaved video streams with a total frame rate of up to 120 frames per second. The channel ID and motion/blind/night detection information can be embedded in the video stream for record and playback purposes. The display multiplexer supports up to eight video windows of which the location and size of each window is configurable. The multiplexed output can be displayed via VGA/LVDS and CVBS interfaces. Also included is a SPOT multiplexer that can tile multiple live camera images and/or live record images on an analog output for displaying on SPOT monitor or time multiplex multiple camera images on a digital output for network function. The TW2851 has an audio CODEC which has four audio ADCs and one DAC. A built-in audio controller can generate digital outputs for recording/mixing and accept digital input for playback. Multiple TW2851 devices can be cascaded to support 8/12/16-channel applications. Up to 32 display windows can be displayed on the PC monitor or LCD panel. Other key features of the TW2851 includes 16-bit bitmap OSG, 2D-deinterlacer, 8- channel nonreal time switching inputs, and flexible record and playback ports supporting BT.656, BT.601, BT.1120 and 24-bit RGB formats.
