error protectionの例文

• Only limited error protection is defined by the standard, and small errors in the bitstream may cause noticeable defects.
• This means that error protection can be added if necessary at a higher layer, for example with a forward error correction scheme.
• This is a CRC code similar to the one used for other layer two protocol error protection schemes such as the one used in Ethernet.
• For instance, many failures per million circuits due to soft errors can be expected in the field if the system does not have adequate soft error protection.
• One HD is broadcast at 720p50 via DVB-S on Astra 1KR : 12.4215 GHz, horizontal polarisation, 27500 symbols / s symbolrate, FEC 3 / 4 error protection.
• The data passes through the encoder, the error protection process FEC ( Forward Error Correction ), through the constellation mapping process and then the interleaving processes the information to create the data blocks.
• Also, the data on a CD has levels of error protection that would mean that even if you could only read a portion of the disk, it might be possible to reconstruct the data.
• The design of the CRC polynomial depends on the maximum total length of the block to be protected ( data + CRC bits ), the desired error protection features, and the type of resources for implementing the CRC, as well as the desired performance.
• The old version of DAB uses punctured convolutional coding for its ECC . The coding scheme uses unequal error protection ( UEP ), which means that parts of the audio bit-stream that are more susceptible to errors causing audible disturbances are provided with more protection ( i . e . a lower code rate ) and vice versa.
• The new DAB + standard has incorporated Reed-Solomon ECC as an " inner layer " of coding that is placed around the byte interleaved audio frame but inside the " outer layer " of convolutional coding used by the older DAB system, although on DAB + the convolutional coding uses equal error protection ( EEP ) rather than UEP since each bit is equally important in DAB +.
• :: : : In the CD-ROM standard there is a second independent level of CIRC data added because the CD-Audio error protection wasn't good enough for most other types of data . ( Uncorrectable audio errors can easily be hidden by interpolation . ) Most ( not all ) drives do allow you to read that CIRC data, but it doesn't exist on audio CDs.
