red book

Different standardization bodies have published their specifications in different colored books. In the case of CD specifications, these are the CD Books. The term Red Book is used for the Compact DiscDigitalAudio( CD-DA) standards and also for network security standards.

1. The Red Book contains the specifications for audio CDs (CD-DA). These were developed by Sony and Philips in 1980 and later adopted by ANSI as the IEC-908 standard. The Red Book specification is the oldest CD specification, and forms the basis for many other CD formats.
   

   CD format specifications

   The Red Book specifies that the playing time is 74 minutes and that the audio data is stored uncompressed. CDs defined according to the Red Book standard may only contain audio data. On such a compact disc there are a maximum of 99 tracks, the stored audio signals are uncompressed, have a resolution of 16 bits and a sampling rate of 44.1 kHz. The 16-bit quantization results in a dynamic range of 96.3 dB. In addition, the Red Book specifications supported error detection( EDC) and, with the CIRC method, an error correction method( ECC).
2. The Red Book for network security is about Trusted Network Interpretation (TNI). These specifications define the technical, functional, and operational security concerns in networks. The Red Book specifications cover the evaluation criteria of all networks, from the local area network( LAN) to the wide area network(WAN). They deal with physical infrastructure, electromagnetic emission and also access permissions. The Trusted Network Interpretation were superseded by the Common Criteria( CC) at the beginning of the century.
