XRCD - Extended Resolution Compact Disc

 


Extended Resolution Compact Disc (XRCD) is a mastering and manufacture process patented by JVC (Victor Company of Japan, Ltd) for producing Red Book compact discs. It was first introduced in 1995.

An XRCD is priced about twice as high as a regular full-priced CD. JVC attributes this to the higher cost of quality mastering and manufacturing.

Technical overview

The XRCD definition refers to the mastering and manufacture process; the resulting CD and the contained data conform to the redbook standard and are encoded at 16 bits, 44.1 kHz. Hence, XRCDs are playable on any compact disc player.

JVC uses advanced dither algorithms (though without noise shaping) in their K2 technology to transfer the analog or digital source to physical disc. The company claims to have studied how inferior CD-remastering techniques degrade the master tape sound and strives to minimize this loss.

Unlike HDCD, the extra four bits cannot be recovered, as this method of mastering only aims to improve dithering to 16-bit, rather than to store extra data.

Note on 22 Jul 2002 Properties and Services The network layer normally offers one of the following services to the transport layer Connection-oriented Connectionless Network layers are designed with the following goals in mind To provide services independent of subnet technology To shield the transport layer from the number, type & topology of the subnets present To use a uniform addressing scheme across both LAN & WAN Virtual Circuits Used in connection oriented services Whenever two machines wish to communicate - a route from source to receiver is setup and remembered Advantages easy congestion control quick to parse subsequent packets Disadvantages setup time vulnerable to crashes Datagrams Used in connectionless oriented services Everytime a packet is sent out, a new route maybe chosen Advantages robust no initia

The Transport Layer

Note on 22 Jul 2002 Services provided Goal of the transport layer is to provide efficient reliable & cost effective service to higher levels (normally applications) Normally provides connection oriented & connectionless services Functions in a similar manner to network layer QoS Another way of looking at transport layer is that it's primary function is to enhance the "Quality of Service" of the network layer What exactly good is, is best left up to the user Connection establishment delay Connection establishment failure probability Throughput Transit delay Residual error ratio Protection Priority Resilience Transport Service primitives Many programs & programmers use transport layer so primitives must be easy to use and understand Primitive PDPU sent Meaning LISTEN none Block until some process tries to connect CONNECT CONNECTION REQ.
