HDTV On Notebooks: Can It Be Done?
As there currently are no HDTV receivers for notebooks, it is not possible to make a statement about their suitability for mobile HDTV televisions. If HDTV decoder cards for notebooks are offered in the future, these will likely be expensive like their desktop PC counterparts, which cost several hundred. As decoding MPEG2 signals is also highly computing-intensive, battery lifetime would suffer greatly through the use of HDTV tuner cards. Thus, if you hope to buy a notebook with an HDTV tuner and battery life of four to eight hours sometime in the near future, we are sorry to disappoint you. Given the current state of technology, only one to two hours of battery life at most are likely obtainable. Under these circumstances, talking about mobility would no longer be appropriate, in our opinion.
Another technical hurdle is the fact that currently there are no notebooks on the market that support DHCP copy protection through the deployment of a DVI or even HDMI connection. Not providing this kind of copy protection would leave the door wide open for pirating, which the film industry obviously would like to prevent. Signal moving in or out of a notebook's DVI in- or outputs not encrypted via hardware could be redirected to a HW or SW recorder relatively easily to make illegal copies of HD content. It is thus a matter of conjecture whether and when notebook HDTV reception will be a reality.
