The lossless high-resolution tracks on the Blu-ray disks may have marketing value, but they are of no benefit to most users. Most players cannot deliver anything better than CD quality to the analog outputs. Unfortunately, these built-in D/A converters are not capable of delivering high-resolution performance. Users are forced to listen to the high-resolution tracks through the D/A converters that are built into the disk player. Blu-ray players are prohibited from having high-resolution digital outputs.

It is not easy to gain access to the high-resolution audio stored on these disks. The Failure to Deliverīlu-ray disks may seem like an ideal solution for the distribution of high-resolution audio, but there are problems. This application note will show how to create a server that will deliver true high-resolution performance. Newer Blu-ray players combine the lossy stream with the residual stream to assemble lossless high-resolution audio that is bit-for-bit true to the original recording. These early players only have access to the lossy compressed stream and are not capable of true high-resolution audio playback. Early Blu-ray players may not fully support these formats. These lossless systems combine a lossy compressed core signal with a residual signal to create a lossless transmission system. These systems support up to 8 channels of 24-bit, 96kHz audio, or up to 6 channels of 24-bit 192 kHz audio.

Dolby TrueHD and DTS-HD are two Blu-ray audio encoding formats that support lossless high-resolution audio.

Blu-ray disks often contain high-resolution audio formats.
