2013年に入って Thunderbolt 2USB3.1SATA3.2MHL 3.0 と新規格の発表が続くなか、HDMI フォーラムが次期規格となるHDMI 2.0を発表しました。

従来のHDMIから進化した点は、端子の形状など後方互換性を維持しつつ、帯域を18Gb/秒へ拡大したところです。またケーブルは従来のハイスピードHDMI ケーブル(カテゴリー2)をそのまま使用可能です。

これにより、4K解像度で60フレーム/秒(2160p)の映像を転送できるようになったほか、最高32チャンネルまでのオーディオ転送にも対応します。

そのほか新しい機能は:
  • 1536kHz までのオーディオサンプリングレートに対応
  • 同じスクリーンを見ている複数のユーザーへ、2系統の映像を同時に提供
  • 最大4人のユーザーへ、マルチストリームオーディオを同時に提供
  • アスペクト比 21:9 の映像をサポート
  • ダイナミック・オート・リップシンク
  • CEC (Consumer Electronics Control) の拡張により、家庭用電子機器の操作範囲が拡大
またHDMI 2.0 の仕様について、HDMI フォーラムは IFA 2013 にて記者会見を開催し、説明をおこなう予定です。

This latest HDMI Specification, the first to be developed by the HDMI Forum, offers a significant increase in bandwidth (up to 18Gbps) to support new features such as 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution; 32 audio channels; as well as dynamic auto lip-sync and extensions to CEC. The complete Version 2.0 of the HDMI Specification is available to Adopters on the HDMI Adopter Extranet.

The HDMI Forum currently has a membership of 88 companies.


"The introduction of the HDMI 2.0 Specification represents a major milestone for the HDMI Forum," said Robert Blanchard of Sony Corporation, president of the HDMI Forum.
