Toshiba Announces Third Generation Video and Audio Decoder LSI with MPEG2 Compliance

Strategic Insights

— 2 min read

Toshiba America Electronic Components Inc. (TAEC) has unveiled its third generation video and audio decoder LSI, the TC81211, which is fully compliant with the moving pictures expert group (MPEG) standard for MPEG2. This one-chip solution is a video and audio decoder with fully integrated, glueless system interfaces, making it a more efficient and reliable option for set-top boxes, digital video disk, multimedia PC boards, and game and entertainment applications.

Key Takeaways:

  • The TC81211 is Toshiba's third generation video and audio decoder LSI, fully compliant with the MPEG2 standard.
  • The chip provides a unique audio and video synchronization mechanism that draws no computational power from the CPU, improving system efficiency.
  • The TC81211 offers a more integrated version of Toshiba's TC81200, an MPEG2 video only decoder released last year.
  • The chip decompresses bitstreams of ISO MPEG2 (ISO/IEC 13818-2) video and MPEG1 (ISO/IEC-11172-3) audio, and features real-time decompression of ITU-R601 resolution picture.
  • The TC81211 has on-chip dynamic random access memory (DRAM) controller support, including fast page mode 256 kilobyte (K) x 16 DRAM and hyper page mode 512K x 32 DRAM.
  • The chip has a built-in direct memory access, automatic 3:2 pull-down and pan and scan functions, and built-in video filters, including a square pixel filter and selectable horizontal filters for a multiple source picture.
  • The TC81211 is packaged in 208-pin plastic quad flat packs, works with a single 27 megahertz clock, and utilizes a 3.3 volt (V) power supply.
  • The chip will be available in April 1996, priced at $150 per chip in lots of ten.
  • A development kit with a PC-based ISA board is also available, which can be used to decode a bitstream and measure signals for quick evaluation of the product.

Statistics:

  • The TC81211 is a one-chip solution.
  • The chip has fully integrated, glueless system interfaces.
  • The chip provides a unique audio and video synchronization mechanism that draws no computational power from the CPU.
  • The TC81211 has 2048 bytes of on-chip boot strap code.
  • The chip has 508 input/output pins.
  • The chip is packaged in 208-pin plastic quad flat packs.
  • The chip works with a single 27 megahertz clock.
  • The chip utilizes a 3.3 volt (V) power supply.
  • The chip has a price of $150 per chip in lots of ten.
  • The development kit with a PC-based ISA board is available for purchase.
