In the battle for HD offerings, everyone is playing catch-up to satellite. For its part, Cable operator Charter Communications is rolling out switched digital video (SDV) across its northern Los Angeles area to stay in the fight. The company plans to deliver more than 40 HD channels in 2008, roughly double its current count. This trial of SDV is expected to be up and running in Q1 2008, with the rollout continuing in other markets over the next two years. Hopefully the trial goes well and the count quickly moves past 40, because that number certainly won't guarantee any bragging rights next to those touted by DirecTV, Verizon or even fellow cable company Cox.
