The GUIDs for the compressed audio formats that are not supported by the HD audio class driver and can be implemented by third-party solutions are listed in the following table. Dolby Digital Plus supports content sample rates of 32 KHz, Based on the information iwc this structure, a user or an application might have difficulty inferring the quality level of the non-PCM stream.

Recommended for surround-sound standard definition movies.

With this information, an application can infer the quality level of the non-PCM stream after it is decompressed and played. To represent an encoded audio stream to be transmitted over an IEC compatible interface, an application must provide: The new structure explicitly specifies the effective number of channels, sample size, and data rate of a non-PCM isc. The characteristics of a decoded audio stream on the target device.

To represent an encoded audio stream to be transmitted 61397 an IEC compatible interface, an application must provide:.

Maximum rate in an audio frame is bps. Since Dolby MAT 2.

For a non-PCM format, these three members have been commandeered 611937 store information about the compressed data in the audio stream. Maximum bit rate in an audio frame is bps. Recommended for surround-sound high definition movies.

Iwc the increase in media storage devices that require compressed audio formats, applications must identify, describe, and use a variety of new encoded audio content for transmitting content from PCs to devices such as HDMI or DisplayPort receiver. However, this structure is also not adequate in describing the stream for IEC transmissions because it was intended to represent a single set of characteristics and used for uncompressed, multi-channel PCM data.

The characteristics of an encoded audio stream to be transmitted. The GUIDs for the compressed audio formats that are transmitted in high bit-rate audio sample packets are listed in ied following table.

Representing Formats for IEC 61937 Transmissions

Recommended for over-the-air music and streaming. When Dolby Digital Plus content is transmitted over IEC oec, the link-sampling rate must be four times the sampling rate of the content. The GUIDs for the compressed audio formats that are available as standard IEC encoded audio formats are listed in the following table.
