Analog Devices has announced an integrated AV front-end for home theatre designs that depend on good AV processing and HDMI specification version 1.4 support for 3D display resolutions. The company's ADV7850 AV front-end is designed for optimising video image, colour quality and audio clarity in HD systems, including HDTVs, AV receivers, video switchers and projectors. The AV front-end joins the company's portfolio of Advantiv advanced TV solutions.
In addition, the front-end chip contains the integrated HDMI receiver to support THX Media Director embedded metadata using multiple VSIs (vendor specific infoframes) facilitating implementation by CE manufacturers into Blu-ray players. THX Media Director is a technology that transforms movies, music, games and digital media into smart content that enables AV components to auto-select the most appropriate audio and video playback settings, preserving artistic intent, claims the company.
The AV front-end offers a 3D comb video decoder with an integrated 170MHz video and graphics digitiser for HD 1080p input formats. The AV front end's 3D comb video decoder offers good processing resolution for motion detection and 3D comb filtering operations without the added cost and design complexity of discrete chip solutions, according to the company.
The front-end chip supports HDCP (high-bandwidth digital content protection) repeater applications and can also be operated as a HDMI transceiver. The AV front-end chip is compatible with the company's other components, including the Advantiv digital crosspoint switches; Blackfin and SHARC processors; the iMEMs microphones; and power management ICs. The front-end chip is available in a 425-BGA package.
