STMicroelectronics announced details of a new generation of decoder chips that will enable hybrid Internet/broadcast-TV set-top boxes (STBs) featured to deliver enhanced user experiences and allow consumers to experience broadcast, Internet or personal content on the TV, intuitively and at any time. The STi7108 joins ST’s successful STi710x video decoders, and also provide features to support 3D graphics user controls, 3D TV, content protection, and connections to external devices.
The new STi7108 has dual ST40-300 CPU host processors linked to a 256K L2 cache giving up to 2000 DMIPS performance and a total of 4000 DMIPs for flexible support of demanding AV, security and connectively applications. A 3D graphics engine enables a new class of user interfaces, supports innovations such as 3D Electronic Program Guide (EPG), and enables advanced Internet content and high-performance gaming on the STB. It is the first set-top box IC in the market to combine 3D graphics, Ethernet, USB and e-SATA interfaces to connect Internet devices, DVR storage or external Flash or hard-disk (HDD) drives.
The STi7108 utilizes the ARM® Mali-400™ graphics processor, the only embedded graphics processor which has demonstrated compliance with the Khronos OpenGL ES 2.0 specifications at HD resolutions, to deliver a powerful 3D experience.
The STi7108 is able to decode video in industry-standard formats, including H.264, MPEG2, VC-1 or WMV9 Internet video, and MPEG4 part 2, up to high-definition resolutions 1080p 50/60 simultaneously with 1080i/720p picture-in-picture or mosaic formats. The device has flexible memory-interface options offering dual 32/16-bit LMI DDR2/ DDR3 at 1066MHz.
The device provides inputs for up to six transport streams, and provides full-motion HD 3DTV over HDMI 1.3 with HDCP copy protection. Support for content sharing, according to the Digital Living Network Alliance (DLNA) specification, will also allow use in next-generation Blu-ray and HD media players.
Together with other integrated processors, including an audio processing subsystem and 2D-graphics handling, the STi7108 allows a significant leap in performance over products currently in mass production, thereby providing increased scope for STB designers to create multimedia value-added features and services to differentiate their products in the marketplace.
