Without knowing more, it is impossible to tell. Do you still have the information that came with your TV? It should say in that.
HDTV stands for High Definition Television. HDTV is a digital television broadcasting standard. Since it is digital, the signals are composed of ones and zeroes -- the language of computers -- instead of waves. HDTV digital signals can contain more information that the old systems. The data can be compressed to allow up to six times more information in the same range of radio waves. Therefore, a broadcaster can send multiple data streams through the limited airwaves they are allowed to use. This is known as multicasting. The old TV standard was for 625 lines (not 525 lines across), with the television screen having a 4:3 "aspect ratio" (that is, the dimensions of the TV screen would be IN A RATIO of 4 to 3). Aspect ratio has very little to do with the broadcast standard - widescreen TV's are not necessarily HDTV (Mine's standard 625 PAL). HDTV can give display of 720 or 1080 lines, and the aspect ratio is 16:9. You can access HDTV with a digital converter on an old television. But this will not give you its full benefits. Newer models of TVs are being built with integrated receivers for HDTV.
Sony, Bose, and Samsung are a few of the top names of Audio receivers. Check your local Radio shack and bust buy for more information about pricing.
