BT plans SDSL technology

Electronics Weekly reports BT as saying “Although ADSL can handle video, it’s not very good. We’ll have to use SDSL”. In a related article, the Financial Times mentions a cable source as saying that the cost per video stream of providing true broadcast television over a fixed line is about 450 times that for ADSL, the high cost of which has been a major factor limiting its adoption. Janice Hughes, of Spectrum Strategy Consulting, justifies investment by pointing out “… consumer spending on entertainment as a share of GDP is growing”. Forbidden’s new codec will have a high quality broadband option that will work over ADSL.
