High-definition video broadcasting and storage require a new generation of optical disc formats. Although the principle of the optical disc drive remains unchanged, the supported video and audio formats provided with the Blu-ray standard and a new generation of user interface and storage require some design updates. This article will discuss this. Design considerations High-definition video broadcasting and storage require a new-generation optical disc format, known as Blu-ray Disc (BD). Although the principle of the optical disc drive remains unchanged, the supported video and audio formats provided with the Blu-ray standard and a new generation of user interface and storage require some design updates. In terms of video, the standard supports MPEG-2, MPEG-4 AVC (H.26?) And SMPTE VC-1 (based on WMV); this generation of players must output in HDMI format. Mandatory audio standards LPCM, Dolby Digital (DD) and DTS digital surround sound, and a variety of optional formats require up to 8 channels of audio to achieve the effect of a home theater. The kernel subsystem includes: DSP / ASSP-Perform MPEG decoding, audio processing, control system electronics, CD-ROM drive and user interface. The ability to integrate multiple functions may require separate solutions for audio and video. Audio-Provides audio output in different formats, allowing audio signals to be digitized by an audio converter and processed by a DSP to provide high-quality audio. Video-Provides video output in different formats: NTSC / PAL, S-video and YPrPb component video and HDMI. The input stage requires a high-performance operational amplifier to amplify the video signal. Memory-stores execution code and data / parameters. User interface – allows users to control the player or home theater using a panel keyboard, remote control or touch screen control. Power Conversion-Converts the input power of the AC adapter to run various functional blocks.
