Here is a look at connections that you may find on a Blu-ray Disc player. Keep in mind that not all of these connections are provided on all Blu-ray Disc players, and the connections that are provided are not necessarily arranged as they are shown in this photo example. Before you purchase a Blu-ray Disc player, take note of the connections that are available on your TV and/or Home Theater Receiver, so that you are best able to match the Blu-ray Disc player with your system.
Starting on the left side of the photo example provided here are 5.1/7.1 Channel analog outputs, which are included mostly on higher-end players. These connections provide access to internal Dolby (TrueHD, Digital) and DTS (HD Master Audio, Core) surround sound decoders and multi-channel uncompressed PCM audio output of the Blu-ray disc player shown here. This is useful when you have a home theater receiver that does not have digital optical/coaxial or HDMI audio input access, but can accommodate either 5.1 or 7.1 channel analog audio input signals.
In addition, just to the right of the 5.1/7.1 channel analog audio outputs are a set of dedicated 2 channel stereo audio outputs. This is provided not only for those that do not have surround sound capable home theater receivers, but for those that prefer a 2-channel audio output option when playing standard music CDs. Some players provide dedicated Digital-to-Analog converters for this output option. However, it must be noted that in some cases the two-channel analog outputs may be combined with the 5.1/7.1 channel analog outputs - in other words, you would use the front left/right outputs of the 5.1/7.1 channel connections for two-channel analog audio playback.
