TW2837-PB1-GE Product Details

The TW2837-PB1-GE is an improved version of TW2835 with four high quality NTSC/PAL video decoders, dual color display controllers and dual video encoders. The device includes four built-in analog anti-aliasing filters, four 10-bit ADCs, a proprietary digital gain/clamp controller, a high quality Y/C separator to reduce cross noise, and a high performance free scaler. The TW2837-PB1-GE has four built-in motion, blind and night detectors and a flexible video display/record/playback controller supporting basic display and MUX functions. The device also has an enhanced 256-color OSD that can display bitmap, single box, 2D array box, and mouse pointer. The built-in channel ID CODEC allows auto decoding and displaying during playback, and the additional scaler on the playback supports multi-cropping function of the same field or frame image. The TW2837-PB1-GE has two NTSC/PAL video encoders with three 10-bit DACs that can support composite and S-video outputs. The TW2837-PB1-GE also has an improved 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. The TW2837-PB1-GE can be configured up to 8/16 channel video controller using chip-to-chip cascade connection. TW2837-PB1-GE is pin-to-pin compatible to TW2835.
