HD blogs ( HDBeat.com, HDBlog,net, HighDefinitionBlog.com ) and a thread at HighDefForum are in yet another discussion on what is considered high definition. Everyone referring to the document from CEA that says:
High-Definition Television (HDTV): The best quality digital picture, widescreen (16 x 9) display with at least 720 progressively scanned lines (720p) or 1080 interlaced lines (1080i) and Dolby digital surround sound.
One thing that was also missed by the crowd is that the CE document speaks about HD Television and not the HD format. Television can have native resolution less than that of the signal type but still be able to display said resolution by scaling the image down and be called an HDTV and not be punished by class actions. When a format is defined by an authority, there is no mention of it being a high definition or not. In fact high definition is not a technical term – it is for marketing only. Same is with so called Full HD, a marketing name for 1080p video format (1920x1080) that is getting wider popularity as 1080p sets hit the market.
