Dolby Digital Plus (DD+), also known as E-AC-3, was developed specifically for the introduction of HDTV and HD-DVD/Blu-ray discs. The codec supports coded-bitstream rates up to 6.144 Mbit/s, compared to 640 Kbit/s for the original Dolby Digital AC-3, and can carry up to 13.1 channels in a single stream. The algorithm is not directly backwards compatible with AC-3 - existing AC-3 decoders will not be able to decode E-AC-3 streams - but Dolby Digital Plus-capable equipment is required to be able to convert E-AC-3 streams to AC-3 for compatibility with existing Dolby Digital A/V processors. As of 2005, HDMI and IEEE-1394 are planned to support a DD+ stream at its maximum defined bitrate. The older and more widespread SPDIF-interface does not have adequate bandwidth for a full Dolby Digital Plus stream (6144 kbit/s). When a DD+ audio track is output to an SPDIF-interface, it must first be downconverted to a lower datarate within SPDIF's capabilities. This downmix is potentially inferior to the DD+ source-bitstream, but still of superior quality to standard AC-3.
