Panasonic Exec Details Blu-ray Tech

25 Jun, 2008 By: Chris Tribbey



Bhanu M. Srikanth, a Blu-ray Disc guru with Panasonic Hollywood Labs, laid out the technology side of the format to members of the Home Theater Forum on Wednesday.

Panasonic is at the leading edge of Blu-ray technology, Srikanth said, and she offered the proof to back her statement up: The company was responsible for the first BD-Java enabled title, the first title to use the MPEG-4/AVC video codec, the first title with enhanced BD+ copy protection and the first BD Live title.

The company does authoring and every type of Blu-ray hardware, imaginable, all of which Srikanth was happy to show off.

“Every title we have done has had some unique feature,” she said of Panasonic's authoring for Lionsgate, Walt Disney Studios Home Entertainment and 20th Century Fox Home Entertainment. “We're not a typical authoring house. We don't do cookie cutter titles.”

Srikanth was especially proud of Panasonic's MPEG-4/AVC video codec, which offers a picture “as close to the master as possible,” she said. “We have been developing and continue to develop our encoding.”

Srikanth also shared several tidbits about Blu-ray's mandatory standards:

  • Dolby Digital, DTS Digital and Linear PCM are all mandatory, with 5.1 channels for the format, while DTS HD Master and High Resolution, Dolby Digital Plus and Dolby TrueHD are optional, as is 7.1 channels.

  • Profile 2.0 requires all players to allow for at least 1GB of space, however, the memory does not have to be internal. For example, Panasonic's DMP-BD50 has an SD card slot for memory, while the PlayStation 3 has a hard drive.

  • “Some BD Live features might require memory,” Srikanth said.

  • All players are required to have parental controls.

  • A Profile 3.0 exists for audio only.
