Friends of the Grand Alliance's Friendship Group launched a full-featured - MobileTV solution

STi 710
The range of applications for digital TV has been extended from traditional terrestrial broadcasting (DVB-T/ATSC), satellite broadcasting (DVB-S), coaxial cable broadcasting (DVB-C), to advanced broadband networks. For the media, system providers provide better and more complete services including:
A, Video On Demand (VOD) Select the program according to your preferences, and repeat the viewing.
B: Online shopping and complete online credit card payment.
C: Internet Movie: Directly connect to a DVD/BD renter to choose a favorite movie.
D: Online interactive teaching.
E: Digital Video Recorder (DVR)

Therefore, in the future, the development trend of TV products will be toward the integration of language, storage and multi-channel development.
In terms of voice: Integrate VoIP capabilities, or video telephony.
In terms of storage: It is integrated hard disk into storage media in multi-channel: It will integrate high compression ratio image format or high resolution HDTV.

Now, STMicroelectronics has released the STi7108, a next-generation decoder chip product that enables network and TV broadcasts, allowing users to use the Internet or view personal content directly on the TV.

The STi7108 is a derivative of the video decoder in the STi710x series. It adds support for 3D graphics user control, 3D TV, content protection, and connection to external devices.

Specifications include
- Two ST40-300 CPU main processors, each with a 256K Layer 2 cache (L2 Cache), processing performance of 2000DMIPS, total processing capacity of 4000DMIP, flexible support for demanding audiovisual , security and connectivity applications.
-3D graphics controller enables a new user interface to support innovative technology applications such as 3D Electronic Program Guide (EPG), view advanced web content on the set-top box, and experience high-performance online games .
- Single-chip integrated 3D graphics control, Ethernet, USB and e-SATA interface set-top box chips for connection to network devices, digital video (DVR) memory or external flash memory, or hard disk drives (HDD) ).
- ARM Mali-400 graphics processor. This product has been tested to be the only embedded graphics processor compatible with the Khronos OpenGL ES 2.0 specification with high image quality, providing a stunning 3D viewing experience.
- The decoder supports industry standard video formats, including H.264, MPEG2, VC-1 or WMV9 network video and MPEG4 part 2 formats with 1080p 50/60 high resolution.
It can also contain 1080i/720p Picture-in-Picture or Mosaic format. STi7108 has flexible memory interface options, providing dual 32/16 bit
1066MHz LMI DDR2/DDR3 memory interface.
- Receive up to 6 streams of input and output full-motion, high-definition 3D TV signals via the HDMI 1.3 interface with HDCP copy protection. Content sharing is also available in next-generation Blu-ray and high-definition media players, according to the Digital Living Network Alliance (DLNA) standard.


Compared with the existing products on the market, the STi7108 has more powerful product performance, and integrates other processors integrated in the chip, including the sound processing subsystem and 2D graphics processing system, to develop multimedia value-added functions for the set-top box designers to ensure Products remain differentiated in the market to provide more opportunities.
