Methods and apparatus for performing signed saturation of binary numbers to arbitrary powers of two are described. Given an n-bit signed binary word, the methods and apparatus of the present invention perform a signed saturation to k-bits where the value of k can vary such that 1kn. Through the use of hardware circuits of the present invention the signed saturation operation is implemented in a more efficient manner than software implementations which utilize multiple compare operations. The signed saturation circuits of the present invention can be incorporated into processors, e. g. , CPUs, to provide a hardware implementation within a CPU for a signed saturation processor instruction, e. g. , either a SISD OR SIMD saturation command or instruction. The signed saturation circuits can accept the data value upon which the operation is to be performed, and, optionally, a value k indicating the number of bits to which individual data value are to be saturated.

Video disc track numbers are conveyed during each video line by means of a quadrature phase shift keyed data carrier recorded along with the picture and sound carriers on a video disc. Upon playback, the data sequence is processed to identify tracking errors occurring within each video field to thereby enable immediate correction of disc tracking errors on a line-by-line basis thus minimizing picture and sound interruption caused by intra-field tracking errors.

Video disc track numbers are conveyed during each video line by means of data subcarriers present in the recorded stereo audio channels. Upon playback, the data sequence is processed to identify tracking errors occurring within each video field to thereby enable immediate correction of disc tracking errors on a line-by-line basis thus minimizing picture and sound interruption caused by intra-field tracking errors.

A procedure for selecting and storing data elements communicated from a common database to users of the database utilizing a communication link between each transmitter and a concomitant receiver accessible by the user. The transmitted information is augmented with attributes which are used at the receiver to select and then store locally only that information of interest to each receiver's user, wherein the attributes and the user selection pattern determine the criteria for storing information locally. Attributes include: utility of each data element in time; interest categories and level of interest for each of the categories determined for the collective users; repeat time to the data element; and a hyperlink to associated data elements.

An architecture for a memory with a wide word, e. g. n-byte, width particularly suited for use as a high definition video frame store memory (80), and an accompanying organization for storing pixel data therein to facilitate efficient block and raster access therefrom. Specifically, the memory relies on storing n-byte wide words (n=(m. sub. 1. times. m. sub. 2)) across m. sub. 2 independent m. sub. 1 -byte wide memory segments, with pre-defined positional offsets between respective m. sub. 1 -byte words (203)("nibbles") stored in successive memory segments. All these segments are simultaneously accessed on a read or write basis. During a memory write operation, all the nibbles in an n-byte wide input word are appropriately shuffled to yield the proper inter-segment offsets prior to being written into the memory as a collective n-byte memory write word. During a read operation, all the nibbles read from memory in a collective n-byte memory read word are appropriately shuffled to yield an n-byte output word. Inasmuch as either a scan line or sub-block (210. sub. W, 210. sub. X, 210. sub. Y, 210. sub.

A device for transmitting digital packetized video and audio data is disclosed. The transmitter includes a video encoder, a prioritizer, and a packetizer. The video encoder receives video signals and encodes the video signals into a digital video data stream including codewords. The video encoder also generates motion vectors and fully intra-coded video frames for use by a video tape recorder during trick play operation. The prioritizer is coupled to the video encoder. The prioritizer receives the digital video data stream and prioritizes the video data according to a preselected prioritization scheme optimized for identifying data useful to video tape recorder trick play operation. The preselected prioritization scheme assigns the video codewords in the video data stream to a priority level according to the utility of each video codeword for video tape recorder recording and playback operation and outputs both the video codewords and a priority level signal. The video codewords and the priority level signal are supplied to a transport packetizer which packetizes the video codewords and associates a header with each packet.
