1. Overview
| TR Number | BTA F-1002 |
|---|---|
| Technical Report Name | (Formatting AES Audio and Auxiliary Data into Digital Video Ancillary Data Space in Bit-Serial Digital Interfaces for 525 line Television System) |
| Enactment Date | 04.1995 |
| General Description | In digital serial transmission of video signals, supplemental signals can be transmitted using blanking intervals. Audio signals are often used as supplemental signals. The interoperability is realized by unifying basic multiplexing conditions of digital supplemental signals and maintaining the compatibility between apparatuses. This technical report specifies the guideline of data structure, packet structure, and multiplexing location with the transmission of digital audio signal in accordance with AEU/EBU standards in supplemental signal periods. This technical report is applied to digital apparatuses, which are mainly used for the 525 television system in broadcasting stations and productions, for transmission of AES audio signals using supplemental signal periods in digital serial interfaces of component and composite signals. |

| AES audio | Data of an AES digital stream which is comprised of audio data and additional data |
| audio data | Data of 23 bits except for additional data of 4 bits in one AES audio sample. |
| additional data | Data of 4 bits every AES audio sample to enhance quantization precision |
| audio control data | Data specifying characteristics of audio data |
