Can I use a Blu-ray player even if I don have a high-definition TV?
Yes, most Blu-ray players have video outputs for standard-definition TVs, such as component outputs (for 480p resolution, the same as a progressive scan DVD player), S-video and RCA outputs. If you’re looking at a Blu-ray player but you don’t yet have a high-definition TV, you’ll want to make sure that player has an output for the highest-quality video connection that your TV supports. In most cases, that will mean component video, sometimes called YPbPr. Older televisions may only have S-video or RCA (also called composite) connections.
