• Digital audio with 1 to 5.1 channels: raw digital audio in PCM, MLP,<br />
Dolby Digital (AC-3), DTS, or MPEG-2. It requires an amplifier/<br />
receiver with a built-in decoder (or a separate external decoder). These<br />
audio connectors come in two different formats:<br />
• S/PDIF coax format, as an RCA connector (IEC-958 Type II).<br />
• Toslink format, as a square optical connector (EIAJ CP-340 and<br />
EIAJ CP-1201).<br />
Some players may have additional audio connections:<br />
• Multichannel analog audio that requires a multichannel-ready or Dolby<br />
Digital-ready amplifier/receiver with six inputs. Provided on six RCA<br />
connectors or one DB-25 connector.<br />
• AC-3 RF audio, but only on combination laserdisc/DVD players. This<br />
carries audio from AC-3 laserdiscs and uses one RCA connector.<br />
• High-resolution digital audio in one of two formats:<br />
• 1394 (FireWire), which is a rectangular connector that requires a<br />
receiver with a 1394 audio input.<br />
• HDMI that requires a receiver/TV with HDMI input.<br />
Some players and receivers support only S/PDIF or only Toslink. If your<br />
player and receiver don’t match, you’ll need a converter, such as the Audio<br />
Authority 977Midiman C02, COP 1, or POF.<br />
Some players can output 96/24 PCM audio using a nonstandard variation<br />
of IEC-958 running at 6.144 Mbps instead of the normal limit of 3.1<br />
MHz. Note that the Content Scrambling System (CSS) license does not<br />
allow digital PCM output of CSS-protected material at 96 kHz. The player<br />
must downsample to 48 kHz. The Pioneer Elite DV-47Ai is the only DVD<br />
player (as of September 2002) with DTCP-protected 1394 output for full,<br />
multichannel 96/24 and 192/24 PCM.<br />
How Do I Hook up a DVD Player?<br />
DVD Technical Details 83<br />
It depends on your audio/video system and your DVD player. Most DVD<br />
players have two or three video hookup options and three audio hookup<br />
options. Choose the output format with the best quality (as indicated) that<br />
is supported by your video and audio systems. See “What Are the Outputs<br />
of a DVD Player?” earlier in this chapter, for output connector details.<br />
On many TVs, you will need to switch the TV to auxiliary input (line input).<br />
You might need to tune it to channel 0 to make this work.
