Abstract: A method for synchronizing media reproduction across heterogeneous networks is presented. The networks include end-to-end IP broadband and narrowband simulcast networks that contain broadband and narrowband devices associated with a common communications group. A controller in the networks determines delay times for reproduction of a media stream across devices in the networks and establishes the longest delay time. The longest delay time is used to calculate appropriate transmission and reproduction timestamps to permit the devices to reproduce the provided media stream in synchronization. Narrowband base stations repeat the media stream at the time specified by a transmission timestamp, and broadband end devices reproduce the media stream at the time specified by a reproduction timestamp. By synchronizing the presentation time, the devices present the media at substantially the same time and are granted fair rights to communicate with one another.

Abstract: A system as disclosed herein is suited for synchronizing unrelated information and/or reference signals originating from two or more broadcasting / multimedia equipment sources wherein the signals may be in different signal formats and/or subject to different delays at a receiving device. The system comprises a master reference time generator connected to at least one of a plurality of slave reference signal generators via a packet network. The master reference time generator comprises a master reference time counter and a sampling device for sampling the master reference time counter. The master reference time generator encodes time data in master reference time packets and feeds these packets into the packet network. The at least one of a plurality of slave reference signal generators is adapted to accept the encoded time data as an input in order to generate a reference signal, the phase of which is calculated based on the time elapsed since an initial time point. The slave reference signal generator comprises a slave reference time counter to generate time data elapsed from the initial time point. The slave reference time counter is connected to a sampling device for sampling the slave reference time counter. The master reference time counter and the slave reference time counter are sampled at time points derived from a time base synchronized on the master reference time generator and all of the slave reference signal generators of the network.

Abstract: A method of clock recovery of Time Division Multiplex signal in a packet network, wherein a first Provider Edge receives (102) a timing message from a second Provider Edge and upon reception of said timing message a counter of said first Provider Edge is increased (104). The first Provider Edge sends (118) to the second Provider Edge encapsulated Time Division Multiplex packet traffic and each packet sent to the second Provider Edge causes the counter to decrease (120). The first Provider Edge compares (106) value of the counter with an Upper Threshold value and with a Low Threshold value and increases a rate of generation of the encapsulation packets if the counter is above said Upper Threshold or reduces the rate of generation of the encapsulation packets if the counter is below said Low Threshold.

Abstract: An optical disc using a single-spiral land and groove track format and an address signal enabling simple sector address management and format compatibility with read-only optical disc media is disclosed. Four physical address areas PID1-PID4 are recorded to a header area such that PID1 and PID2 are offset one-half track pitch toward the outside circumference of the disc from the groove track center, and PID3 and PID4 are offset one-half track pitch toward the inside circumference of the disc from the groove track center, and the header area is shared by groove track sectors and land track sectors. A groove track sector address is written to PID3 and PID4, and the sector address of the land track sector adjacent on the outside circumference side of that groove sector is written to PID1 and PID2. The address of each sector increases (1) in the same sequence as the sectors are formed in the recording spiral.
