Design Considerations

High-definition video broadcasting and storage requires the use of Blu-ray, also known as Blu-ray Disc (BD) as next-generation optical disc format. While the principle of optical disc drives remain the same, the supported video and audio formats coming with the Blu-ray standard as well as next generation user-interfaces and memories requires some updates in the design.

On the video side MPEG-2, MPEG-4 AVC (H.264) and SMPTE VC-1 (based on WMV) are supported by the standard; HDMI output is a must for this generation of players.
The mandatory audio standards LPCM, Dolby Digital (DD) and DTS Digital Surround plus several optional formats require up to 8 channels audio for home theater.  

The core subsystem includes:

  • DSP/ASSP – performs MPEG decoding, audio processing, controls system electronic, optical disc drive, and user interface. While many functions can be integrated there might be a need for discrete solutions on the audio and video side.
  • Audio – provides audio output in different formats as well as allows the audio signal to be digitized by the audio converter and processed by a DSP to provide high-quality audio.
  • Video – provides video output with different formats: NTSC/PAL, S-video, YPrPb component video and HDMI. The output stages require high-performance op-amps to amplify the video signal. 
  • Memory – stores executing code and data/parameters.
  • User Interface – allows the user to control the player or home theater using the panel keypad, remote or touch screen control.
  • Power Conversion – converts the input power from the AC adaptor to run various functional blocks.
