TANDBERG TT1260 B.3 Audio Output Format

Technical Specification

Page B-6 Instruction Manual: TT1260 Standard Definition Professional Receiver/Decoder

ST.TM.E10100.1

B.2.2 MPEG Audio

The TT1260 supports decoding of MPEG audio as follows:

· Compression layers: MPEG-1 layers I and II

· Sampling rates (kHz): 32, 44.1, 48

· Maximum compressed data rate: 384 Kbit/s (layer II)

B.2.3 Dolby Digital AC-3 Audio

The TT1260 is able to decode and output the primary stereo pair of a

Dolby Digital AC-3 encoded audio stream. When there is data encoded on

the audio surround channels, the Decoder applies downmixing, so that

either a surround encoded stereo pair (LtRt downmix) or a conventional

stereo pair (LoRo downmix) is available at the output.

The TT1260 is not able to decode and output all 5.1 channels individually

as separate channels.

It is possible to output the compressed Dolby Digital stream from the

digital audio output, allowing it to be decoded to 5.1 channels by an

external Decoder.

Sampling rates (kHz): 32, 44.1, 48

Maximum compressed data rate: 640 Kbit/s

NOTE…

Support for Dolby Digital decoding requires approval and licensing from Dolby.

B.2.4 Linear Audio

The TT1260 is able to receive audio data in the form of linear PCM digital

audio data, up to 20-bits in resolution, and makes it available for output as

either analogue or digital audio.

A maximum of four audio channels can be decoded from one PES stream.

B.3 Audio Output Format

B.3.1 General

The TT1260 provides an independent stereo pair output for each audio

channel. Analogue audio is always output and the following Digital audio

formats can be chosen from the User Interface and remote control

interfaces:

· IEC958 CON

· AES3

· Digital IEC958 compressed (Dolby Digital Digital ONLY)

· Digital Audio embedded into the Ancillary Data Space of the Serial

Digital Video Output.
