The actual algorithms used to encode and decode the television guide values from and to their time representations were published in 1992, but only for six-digit codes or less. [1] [2] Source code for seven and eight digit codes was written in C and Perl and posted anonymously in 2003. [3]
For example, an overall code rate of 1/2 may be achieved by puncturing the outer convolutional code to rate 3/4 and the inner convolutional code to rate 2/3. A recursive inner convolutional code is preferable for turbo decoding of the SCCC. The inner code may be punctured to a rate as high as 1/1 with reasonable performance.
Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was used to print the document.
The last of the previously unused ESN codes were allocated in November 2008. [3] Applications for assignments were accepted until June 30, 2010 using reclaimed ESN codes, those previously assigned to AMPS or TDMA phones and therefore not present on CDMA2000 systems. Reclaimed codes have also been used for UIMID assignments. Codes are assigned ...

VIN on a Chinese moped VIN on a 1996 Porsche 993 GT2 VIN visible in the windshield VIN recorded on a Chinese vehicle licence. A vehicle identification number (VIN; also called a chassis number or frame number) is a unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters and mopeds, as defined by the ...
The off-by-one errors (for example 254 instead of 255 and 1 instead of 0) happen because the 8 bit Y'PbPr values were used when decoding to R'G'B', if you use 10-bit Y'PbPr that does not happen. Y'PbPr (and Y'CbCr ) values of 75% (100/0/75/0) SMPTE ECR 1-1978 color bars (0.75 * 219 + 16 = 180) using BT.709-2 matrix coefficients as written in RP ...
