摘要： The present invention provides a system, method and apparatus for encrypting/decrypting plain data/cipher text having lengths not equal to a multiple of a data chunk of a block cipher algorithm. The present invention enables plain data having a length that is greater than or less than one data chunk to be encrypted to produce an encrypted version of the plain data having the same length. Further, the present invention enables cipher text having a length that is greater than or less than one data chunk to be decrypted to produce a decrypted version of the cipher text having the same length. Decryption of cipher text having a length that is greater than one data chunk uses two rounds of decryption. A first round of decryption recovers an indirectly encrypted portion. A second round uses the indirectly encrypted portion to completely recover the original plain data.

摘要： In conventional packet communications systems, such as MPEG-2, the data stream includes a program clock reference (PCR) so that the receiver decoder can lock on to the data stream. The invention eliminates the need to send the PCR by transferring a data transport rate explicitly in the header of the data packets so that the decoder can use the transport rate as a locking reference and adjust its phase lock loop. The transport rate is carried in the adaptation field as user private data.

摘要： A transcoder (10) and a decoder (80) reconstruct an image from still image compressed data, such as EXIF data. The transcoder transcodes the still image compressed data into a bit stream of moving picture compressed data, such as an MPEG-2 4:2:2P bit stream with only intra pictures. The decoder (80) decodes the bit stream of moving picture compressed data into a still picture image that can be stored in a digital memory (100).

摘要： A system, method, and apparatus for handling transition errors is presented herein. The transition errors include handling unreported time base discontinuities during trick mode transition, miscalculated time stamps during trick mode transition, erroneous sequence end codes, and unreported broken group of picture transmission. Unreported time base discontinuities are detected by comparing the program clock reference (PCR) value of the data packet to the system time clock (STC). If the difference exceeds a predetermined threshold, the STC is set to the PCR value. Miscalculated time stamps are detected by examining the difference in PTS values between temporally adjacent data packets. If the difference is not within a margin of error from predetermined value, the PTS is disabled. Unreported broken groups of pictures are handled by skipping the first two B-frames of the first group of pictures following a trick mode transition. Erroneous sequence end codes are detected by determining whether a packet containing a sequence end code is associated with a time base change. If the packet is not associated with a time base change, the sequence end code is disregarded.

摘要： Aspects of a method and system for converting a DSS stream to an encrypted MPEG stream are provided. In some applications, for example, an access device such as a set-top box may require the conversion of DSS proprietary transport streams to standardized MPEG transport streams in order to communicate with an external MPEG device, such as a personal computer. In this regard, conversion of a DSS stream to a MPEG stream may require the conversion of DSS formatted timing/synchronization information into MPEG formatted timing/synchronization information. Additionally, some applications may require the converted MPEG stream to be encrypted utilizing AES counter encryption. In this regard, when converting the DSS stream to an MPEG stream, the data may need to be packetized appropriately to enable the AES counter encryption.
