Patent NO-892080-D0 (NO)
Inventor: BENNETT CHRISTOPHER JOHN
IPC: H04N7/167
Filed: 1989-05-24
Abstract: A key security system provides for the reproduction of secure keys by using distributed key generation data and a distributed encrypted prekey. The system encrypts program key generation data (17) with a program key prekey (18) in accordance with a first encryption algorithm to produce the program key (20); processes the program key (20) to produce a keystream (25); and processes an information signal (26) with the keystream to produce a scrambled information signal (27). The program key prekey (18) is encrypted with a category key (22) in accordance with a second encryption algorithm to produce an encrypted program key prekey (23). The scrambled information signal (27) the program key generation data (17) and the encrypted program key prekey (23) are distributed to descramblers. The descrambler within the key security system decrypts the distributed encrypted program key prekey (23) with the category key (22) in accordance with the second encryption algorithm to reproduce the program key prekey (18); encrypts the distributed program key generation data (17) with the reproduced program key prekey (18) in accordance with the first encryption algorithm to reproduce the program key (20); processes the reproduced program key (20) to reproduce the keystream (25); and processes the distributed scrambled information signal (27) with the reproduced keystream (25) to descramble the distributed scrambled information signal. The key generation data includes authorization data that must be processed by the authorization processor (35) in the descrambler in order to enable the descrambler. The use of authorization data as key generation data protects the authorization data from spoofing attacks. When more data must be protected than a single operation of the encryption algorithm can support, then additional data blocks are protected by chaining the system, wherein the output from one stage forms part of the input to the next. The key generation data for the program key includes a sequence number securely associated with the category key to thereby "timelock" program key reproduction to the use of a current category key and thus prevent an attack based upon the use of an obsolete category key.

Abstract: In a method for coding an audio signal digitized at a low sampling rate to obtain time domain audio samples. A frequency domain representation of the time domain audio samples is produced. The frequency domain representation includes successive frequency lines. These frequency lines are grouped into a plurality of scale factor bands. The successive frequency lines in a scale factor band are coded with the same scale factor. A plurality of regions is formed by grouping the scale factor bands, wherein successive scale factor bands form a region within which all the scale factors are coded with the same number of bits, which is determined according to the largest scale factor of the region. The scale factors assigned to scale factor bands within the highest region that includes the higher frequency successive frequency lines are set to zero. The frequency lines in the highest region are coded using the zero-valued scale factors that correspond to a multiplication factor of 1. The scale factors for the highest region, however, are not coded. Thus, the bits that would be required for coding these zero-valued scale factors are saved and can be used for a finer quantization of the rest of the spectrum. Additionally, this coding method when applied to ISO/IEC 13818-3 as a low sampling rate modification thereof only requires minimal changes with respect to this Standard.

Title: Video coder
IPC: H04N21/242
Filed: 1987-09-23
Abstract: A coder assembles bursts of blocks of image data (eg transform coded coefficients) and associated overhead data into a sequence of data which are then transmitted. Both the transform coded coefficients and the overhead data are initially stored in separate FIFO memory stores (21)(22). The blocks of transform coded coefficients have a 'last coefficient' flag accompanying the last coefficient, and the overhead information contains a unique word SWITCH, after the header information but before the 'end-of-block' flag. The 'last coefficient' flag and the SWITCH word are recognised by a toggle controller (29) which controls the reading of the stores so that the coefficient data and overhead data are selectively passed to a buffer (30) in a desired sequence. The buffer (30) is followed by a variable length coder (31) which supplies the output of the coder at a constant bit rate. Provision (34-38) is made to calculate the quantity of output data represented at any time by the contents of the buffer and the result is used to control the rate of generation of image data.
