Broadcom Corp. unveils its next generation of digital TV (DTV) SoC solutions designed for digital video broadcast (DVB)-based platforms to address European and Asian markets. By supporting global connectivity standards such as a digital video broadcast-terrestrial (DVB-T) demodulator, phase alternating line (PAL), sequential colour with memory (SECAM) video support, and near instantaneous compounded audio multiplex (NICAM) audio support, the SoC allows TV manufacturers to create products that offer distinguishing features, says Broadcom.

The BCM3556 single-chip DTV solution supports multiple compatibility standards in Europe and Asia. The DTV SoC also includes an advanced feature set including multi-format picture decoding in support of high definition AVC, H.264, VC-1, AVS and MPEG-2 streams. By supporting H.264, the latest video compression standard, the users are enabled to view multimedia and HD content with improved picture quality at lower bandwidth when accessing content from other consumer devices in the home network, claims Broadcom. The BCM3556's support of H.264 also provides access to H.264 broadcast content without the need of an additional decoder within the DTV.

The BCM3556 also integrates a host of features such as a 3D graphics core that provides consumers with a graphical user interface for flipping, rotating, moving or manipulating images, and enables OEMs to create specialised user interfaces that differentiates the TV from traditional flat, two dimension user interfaces.

Meanwhile, the advanced home network connectivity of the BCM3556 includes an integrated Ethernet media access controller and physical layer device that enables the SoC to connect with multiple home networking devices such as media servers, PCs, MP3 and portable media players.

The BCM3556 is available in package configurations that support WXGA (wide screen) display resolutions and a full 1080p high definition resolution. The new DTV SoC also incorporates a unique 3D colour management system, as well as digital, analogue and mosquito noise reduction. Also integrated is an advanced picture enhancement processor to improve picture sharpness and perform picture post-processing functions. The PEP engine is fully programmable and can be optimised by each TV manufacturer.

The BCM3556 DTV SoC solution is now sampling to early access customers. Pricing is available upon request.
