A CRT TV that's designed only for 480i can't handle 480p. This particular TV model (KV-32XBR250) is 480i only and is too old to have HDMI. HDCP is irrelevant.
It might be able to display a 320x240 video signal, but that depends on how sloppy the vertical sync circuitry is in the TV. Sony's XBR TVs were very well designed, so it probably won't work.
Traditional NTSC TV video is not at all like computer video. It was designed to make the best use of low bandwidth radio transmissions, taking shortcuts which are made possible by how the human eye works. In modern notation, the video signal is called 480i -- i = interlaced, and it actually has more than 480 scanlines per frame. Being interlaced means that half of the scanlines -- every other scanline, the odd numbered ones -- are transmitted during one field in the first 1/60 of a scond, and then the signal goes back up to the top of the screen and the other half of the scanlines, the even ones, are sent during the second 1/60 of a second. The human eye normally can't respond that fast, so it looks like you're getting the whole screen at once, but you aren't. In contrast, computers use progressive video (e.g. 480p). All "480" of the odd and even scanlines are drawn sequentially from the top to bottom of the screen each 1/60 of a second. (i put 480 in quotes because the actual number of scanlines is greater than that.)
