摘要： For encoding, each video frame is segmented into slices; each slice, into macroblocks; and each macroblock, into blocks. Encoded macroblock and block signals are generated corresponding to macroblock and block information of each slice, respectively. An encoded bitstream is generated in accordance with the encoded macroblock and block signals, wherein all of the macroblock signals for each slice precede all of the block signals for each slice. For decoding, an encoded bitstream is received, wherein (1) a portion of the encoded bitstream corresponding to each video frame corresponds to slices; and (2) a portion of the encoded bitstream corresponding to each slice comprises encoded macroblock signals followed by block signals for the entire slice. The macroblock and block signals of each slice are decoded and decoded video signals are generated in accordance with the decoded macroblock and block signals.

摘要： Reference frames are generated by selectively filtering blocks of decoded video frames. The decision whether to filter a block is based on a comparison of an energy measure value generated for the block and an energy measure threshold value corresponding to the quantization level used to encode the block. The energy measure threshold value for a given quantization level is selected by analyzing the results of encoding and decoding training video frames using that quantization level. The reference frames are used in encoding and decoding video frames using interframe processing.

摘要： Techniques for establishing a connection with a calling party and a called party using the processing of an intermediary serving arrangement so as to minimize telephone costs and preserve privacy. During a first established telephony connection, the intermediary arrangement stores two telephone numbers as remotely provided by the calling party. The calling party and serving arrangement are connected during a second established connection using the first telephone number. The called party and serving arrangement are connected during a third established connection using the second telephone number. Upon successfully establishing the second and third connections, the calling party and called party are bridged for conversation.

摘要： A subscriber line interface circuit includes a switched hybrid circuit operable during a POTS mode when the associated subscriber is using a POTS station and in an ISDN mode when the subscriber is using an ISDN station. The hybrid circuit includes a first amplifier circuit for coupling a signal at the two-wire port thereof to its four-wire transmit port, and a second amplifier circuit for coupling a signal at the four-wire receive port of the hybrid to the two-wire port. A high termination impedance is synthesized at the two-wire port during the POTS mode and a low termination impedance at the two-wire port during the ISDN mode. The signal from the four-wire transmit port is converted to a digital signal and applied to a digital signal processor which is configured differently according to DSP running programs respectively stored in first and second memories for operations during the POTS and ISDN modes. The DSP processes signals received from the hybrid's four-wire transmit port as well as from the telephone switching system according to the program supplied from the first or second memory and applies the process signals to the switching system and the four-wire receive port.

摘要： A test system directed to apparatus for transmitting and receiving multiple telephone transmission signals over a single twisted pair. The system converts an analog signal from a local switching station to an 80 ksymbols/sec signal for transmission over a twisted pair by a line card. A remote terminal converts the 80 ksymbols/sec signal back into a conventional analog signal for use in conventional telephone, facsimile or other related equipment. The test equipment separately tests the entire system, the line card portion of the system, the remote terminal portion of the system, and the twisted pair.

摘要： An apparatus for providing passive bus communication in an ISDN without use of services of a central office includes a passive bus suitable for ISDN D-channel frame communication, the passive bus having an echo channel and having a plurality of terminal devices coupled to the passive bus. A receiving circuit is coupled to the passive bus for receiving D-channel frames containing a SAPI address transmitted from the terminal devices over the passive bus. A decoding circuit is coupled to the receiving circuit for decoding D-channel addresses transmitted from the terminal devices over the passive bus. The decoding circuit includes a circuit for determining if one of the D-channel frames from the terminal devices include a predetermined SAPI address. A switching circuit is coupled to and responsive to the decoding circuit, and implements a logical communication channel between two or more of the plurality of terminal devices when the D-channel frame includes the predetermined SAPI address. The switching circuit echoes D-channel frames over the echo channel of the passive bus for receipt by the terminal devices (TE) coupled to the passive bus and inhibits transmission of the D-channel frames to the central office when the D-channel frames include the predetermined SAPI address. The TE monitors the D-echo channel to receive the local passive bus communication in addition to contention resolution.
