Robust reception of digital broadcast transmission

A method and apparatus for improving the reception of digitally modulated signals. A main signal and a supplemental signal are provided in the transmitter. The signals may be substantially identical except that the supplemental signal is advanced in time with respect to the main signal. The main and supplemental signals are sent from the transmitter to the receiver modulated on a signal. At the receiver, the supplemental signal is stored in a buffer. If the main signal is undesirably changed during transmission, corresponding portions of the supplement signal are substituted for the undesired portions of the main signal.

Method of transmitting/receiving control message in a mobile communication system providing multimedia broadcast/ multicast service

A control message transmitting / receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.

Method, system and apparatus for transmitting, receiving, and reproducing a digital broadcast signal

The present system comprises a transmitting apparatus for digital broadcast which includes an original signal generating section, delaying section, information amount reducing section, and transmitting section. A receiving and reproducing apparatus for digital broadcast includes a signal reception front stage unit for receiving a high quality signal and a low quality signal, mode determining section and reproducing section composed of a delaying section and selecting section for selectively reproducing the high quality signal and the low quality signal. By employing time diversity, the transmitting apparatus sends the low quality signal having a smaller bandwidth and the high quality signal so that the low quality signal has a preceding time lag relative to the high quality signal, and the receiving apparatus reproduces broadcasting programs. Utilizing the frequency band for broadcast effectively, many broadcasting programs can be increased, and the investment for providing a gap filler can be minimized.

Techniques for utilization of spare bandwidth

A packet encapsulator includes a filter module that identifies one or more carousel packets from a plurality of received packets. These one or more carousel packets are then stored in a packet buffer. The packet encapsulator also includes a channel queue for enqueuing packets for transmission across a broadcast transmission medium. For instance, the channel queue also receives the forwarding packets from the filter module. The channel queue also receives the one or more carousel packets from the packet buffer when at least a predetermined amount of available bandwidth exists in the broadcast transmission medium. The broadcast transmission medium may be a digital broadcast network such as a DVB handheld (DVB-H) network or a DVB terrestrial (DVB-T) network. Alternatively, the broadcast transmission medium may be a cable network.

Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy WID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”. In conjunction 20 with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.

Prioritization of data

Prior art methods of receiving, organizing, and implementing the data transmitted to mobile devices, such as ESG fragments, have a great impact on mobile device performance and battery lifetime. Furthermore, in order to keep server side and client side ESG fragments in synch, any change in content of ESG fragments needs to be indicated. Additionally, any change in how ESG fragments are distributed requires the client side to verify if all the fragments are still available and valid in any new distribution set up and if their content has not changed. Aspects of the invention provide a protocol for prioritizing the ESG fragments to ensure the end user of a destination device receives more pertinent ESG data in a timely manner. Other aspects of the invention minimize the number of updates required on a client side or destination device caused by the re-distribution of the “unchanged” ESG fragments into different carousels.

Disclosed is a DMB data receiving apparatus and method for improving a DMB data receiving speed. According to the DMB data receiving apparatus and method, if there are predetermined MSC data, which have not been received or received with an error when receiving MSC data by a DMB reception terminal, the DMB reception terminal can receive the predetermined MSC data through a return channel established between the DMB reception terminal and a broadcasting station. In detail, if there are predetermined MSC data, which have not been received or received with an error, the DMB reception terminal request the broadcasting station to transmit the predetermined MSC data and to allow establishment of a return channel, and then receives the predetermined MSC data through a return channel established based on the request. Therefore, when some MOT content data have not been received or received with an error, the DMB reception terminal can immediately receive the corresponding MOT content data without waiting until the next MOT data transmission period begins, thereby greatly improving the DMB data receiving speed.
