The Austin PBS station KLRU has four DTV channels; in the evening channel 1 broadcasts in 720p (~14Mbps), channel 2 in 480i (~3Mbps), and 3 and 4 are "off the air", but actually broadcast programs in 240i (~256Kbps). Most of the time the display is non-changing and very pixelated, but the audio comes through fine.


Could you tell me how you determined that they were using 240i? Does your receiver have that data or did you record the bitstream to a computer and analyze it?
