Please Help Me Hook Up a Blu-Ray Player!?

Q. I have a 52" HD TV (1080p) and a JVC surround sound system that only plays regular DVDs. I want to buy a Blu-Ray player to put into this system. How do I hook it up? Please don't tell me I have to buy a new surround sound system to go with the new Blu-Ray player!


Answer
You may not need to replace your surround sound system! It depends upon the capability of your JVC system. Both the Sony BDP-S300 (does not support Blue Ray final standard profile) & Panasonic DMP-BD30K (supports Blue Ray final standard profile) support the output of 5.1 channel audio. If your JVC surround sound system can input these 6 signals (front L, front R, surround L, surround R, center & sub) you are in business. Other Blue Rays may support this as well; I am just not as familiar with them.

The Panasonic also outputs the audio via coax or optical cables. In any case, you would still use an HDMI or component video cable to your TV. On the Panasonic unit, you can configure this unit to disable the sound over the HDMI so your TV does not interfere with Blue Ray playback.

Additional Details: Just got home from work and verified that the Sony, Panasonic, Samsung & Sharp Blue Ray players all support 5.1 channel, coax and optical audio outputs.

Does Blu-Ray really make a quality difference?

I like the idea of using internet apps on a Blu-Ray player, but does it REALLY make a quality difference in the picture and sound?


Answer
Yes. Blu-Ray movies are encoded with a much higher resolution than DVDs. There are less than 350,000 pixels of detail per frame on a DVD movie, and more than 2,000,000 pixels per frame on a Blu-Ray movie.

DVD movies are more heavily compressed (leaving unwanted compression artifacts behind) averaging about 5-6 Mbps in bitrate whereas Blu-Ray movies are typically encoded with a ~40 Mbps bitrate. (To be fair, Blu-Rays do require a higher bitrate to maintain the same level of compression as DVDs because Blu-Ray movies have much more detail to encode, but there are still less compression artifacts on Blu-Ray movies regardless).

DVDs are limited to 5.1 channel compressed audio whereas Blu-Ray movies can be encoded with up to 7.1 channels of HD audio.
