The Sony player will support a video output at 1080 lines of resolution and progressive scanning, the company said in a statement. This is dubbed "full HD" and is the highest of several video formats considered high-definition. As a concession to content providers, the full HD output will only be available via an HDMI (high-definition multimedia interface) connector that supports copy protection. Owners of TV sets without an HDMI connector will be able to watch up to a 1080-line interlaced signal, which is the second highest rank of high-definition picture.
Sony has priced its first desktop computer that will have a Blu-ray Disc burner. The drive will be able to write to 25GB and 50GB BD-RE (rewritable) and BD-R (write once) discs. Sony will start selling 25GB BD-RE and BD-R discs in April for $20 and $25 respectively and 50GB capacity versions of the same discs later in the year for $48 and $60 respectively.
The Vaio RC will be launched in "early summer" and will cost around $2300. At the CeBIT show in Germany last week, Sony announced plans for a Vaio notebook with a Blu-ray Disc drive.
