Visual Systems

Advances in resolution from conventional full HD through 4K to 8K, together with an increase in audio quality, are driving the market in broadcasting and web content. At Socionext we develop leading-edge SoCs by combining the latest technologies. Technologies such as Codecs, AV processing and encoding/decoding in single-chip solutions supporting playback, display and protection of visual content. These products need to support a wide variety of audio and video formats and be able to offer the performance necessary to provide ‘a better quality of experience’.

Broadcasting standards vary from region to region and depending on the delivery mechanism used (terrestrial, satellite, cable), Socionext’s field-proven products support all required demodulation and error-correction technologies for worldwide deployment.



Socionext’s latest digital TV front-end demodulator LSI supports both DVB and ISDB broadcast systems for worldwide platforms. The SC1502AF-02, for DTV/STB applications, has a dual-type demodulator for terrestrial/cable/satellite broadcasts.


  • At 7mm x 7mm it is the smallest package size in the world* as a dual-type demodulator LSI. (*According to our research.)
  • High Connectivity with various tuners.
  • Demodulator LSI that is compatible with ISDB-S3 and channel bonding technology based on ITU-T J.183.
  • Output MMT(MPEG Media Transport)/ TLV(Type Length Value) stream that is selectable from TLV format and IP format.

Socionext has developed "3D surround sound technology" for providing a sense of presence in the reproduced sound by making full use of spatial acoustics technology. When applied to gaming devices or digital signage equipment, this technology can enhance the sense of presence in the game or increase the effectiveness of signage advertisements, thereby making the sound reproduction with products using the technology more attractive.

This technology, which has already been used in game software products from famous manufacturers, has an extensive track record of selling in the market.


  • Provides listeners an amazing sense of presence as if the sound source was close to their ears
  • Controls the direction of the sound coming from the speakers with only the front speakers
  • Requires no hardware modifications because you only need to play back sounds processed with a 3D sound authoring tool


The technology can be applied to a wide range of products, including gaming consoles for home-use, gaming devices, digital signage equipment, and arcade games.

Illustration of Use of Technology in Customer Environment

  • You only need to process a sound object into a 3D sound object to obtain 3D surround sound effects
  • We will provide a 3D sound authoring tool tuned to suit your reproduction equipment
