Nextchip Video Decoders

Nextchip are a fabless semiconductor company that specialise in the design and manufacture of ICs for the video / surveillance industry. There range of video codecs, support SD and HD encoding and decoding supporting H.264, MPEG-4 and MJPEG standards.

Featured Product NVP1114B

NVP1114B includes 4-Ch video decoder, 1-Ch video encoder and 4-Ch audio codec, which guarantees high quality images. It accepts separate 4 CVBS inputs from camera, TV, DVD and other video signal sources. It digitizes and decodes NTSC/PAL video signal into digital video signal which represents 8-bit CCIR656 4:2:2 format with 27MHz , 54MHz or 108MHz multiplexed. 1-Ch video encoder plays roles of converting the digital ITU-R BT.656 format data into CVBS, Y and C in 10bit resolution. 2-Ch DAC is fed from the video encoder. 4-Ch audio codec, which is 4-Ch PCM audio codec IC, handles audio band signals(300Hz~3400Hz) with 16bit linear PCM, 8-bit G.711(μ-law, A-law) PCM. Built-in audio controller generates digital outputs for recording/mixing and accepts digital input for play back.
