European HDTV Receiver Specifications

As DVB does not specify which audio coder should be used for next-generation broadcasts, various broadcaster/manufacturer groups have recently worked collaboratively to gain consensus on the formats desired by broadcasters, which will then be included in European receivers. The key outcomes for multichannel format requirements so far are described in the table below.

The EBU Project Group D/MAE states that Dolby Digital Plus and HE AAC with Dolby Metadata are the best candidates for broadcasting HDTV. It also states that both Dolby Digital Plus and HE AAC have advantages, and a single preference cannot currently be identified. Dolby Digital Plus offers consistently great performance at 448 kbps and above; HE AAC offers remarkable performance where data rates are limited, providing a multichannel audio signal as low as 160 kbps.
