摘要： Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of signaling data over a network. Signaling data is encoded, partitioned into M signaling segments, and distributed over M corresponding data frames. A data stream with the partitioned signaling data is transmitted through a digital terrestrial television broadcasting system, where the partitioned signaling data may include physical layer configurable data. The number of distributed signaling segments may be determined from a predetermined value or from a parameter contained in pre-signaling data. The number of physical layer pipes supported by signaling data may be increased by separating the static signaling part and the dynamic signaling part, dividing static signaling part into signaling segments, and interleaving the signaling segments over the data frames. The number of physical layer pipes can be further increased by adding at least one P2 symbol.

摘要： Embodiments are directed to transmitting receiver-capacity-signalling data that specifies a plurality of receiver capacities to be used for receiving a service. The signalled receiver capacities may include: a type of time interleaver being used and a minimum burst interval between two consequent bursts. The signaled receiver capacities may also specify: how often a physical layer pipe appears in frames, and/or a number of a frame in which a physical layer pipe appears for a first time during a super frame. Embodiments are directed to receiving the receiver-capacity-signalling data and if, based on the received receiver-capacity-signalling data, receiver capacity is sufficient for one or more selected services, performing service discovery and decoding the one or more services. Otherwise, decoding the one or more services may not be performed.

摘要： A system and method is provided for ensuring that time for tuning to another RF channel between two TF frames in TF slicing exists while reception with a single hopping-tuner is enabled, and reception for terminals can be guaranteed when transmitting and receiving common services. An additional time for tuning is introduced for TF-sliced services, where the time for tuning can be inserted either before of after the P1 & P2 symbols, and the symbols allocated for the tuning time can also be used for transmission of low-bit rate services. Alternatively, additional padding bits and a guard period can be added in the event that slots or slot fragments exceed a cyclic transfer border upon time shifting. Alternatively still, the tuning time is represented by a complete TF frame, where the complete TF frame carries services other than those in the first TF frame, so that a service is transmitted in every second TF frame and a receiver can perform tuning during the TF frames which do not carry the service.

摘要： Embodiments are directed to first and second OFDM pilot symbols. The first and second pilot symbols may have first and second sets, respectively, of allowed, forbidden, and active carrier frequencies. The second sets of carrier frequencies may be formed by frequency shifting the respective first sets by a predetermined frequency, such as the frequency difference between adjacent carriers. An embodiment is directed to frequency translating part of a first received pilot symbol by one carrier interval in a first direction, frequency translating part of a second received pilot symbol by one carrier interval in a second direction that is opposite from the first direction, and forming a correlation by multiplying the frequency translated parts of the first and second pilot symbols by complex conjugates of parts of the pilot symbols upon which frequency translation has not been performed, and summing the multiplication results.

摘要： An improved system and method for transmitting a multiplexed service stream over an error prone DVB-H channel. Media IP packets are priority labeled. For each time slice burst, the IP packets are grouped based upon the priority labels. MPE-FEC matrices are made for the different priority labels in each time slice burst. RSDT columns are computed such that the average service bit rate does not overshoot the maximum allowed service bit rate, and the protection increases with priority. The ADT and RSDT of the MPE-FEC matrices are then encapsulated into MPE-FEC sections.
