Abstract:
A system and method for efficiently communicating messages over a low-rate channel between multiple devices in a system for wireless communication of uncompressed video is disclosed. The method includes using multiple destination aggregation to improve the efficiency of the low-rate channel, thereby allowing more time to utilize a time division duplexed high-rate channel for communicating the uncompressed video. The multiple destination aggregation messages can be encoded by any device in the system and received over the low-rate channel by any other device in the system. Receiving devices can determine if any of the multiple messages received over the low rate channel are targeted to the receiving device and subsequently process these messages.
Abstract:
An apparatus for controlling fraud in a satellite signal delivery system. An apparatus in accordance with the present invention comprises a receive antenna for receiving at least one satellite signal, and a module, coupled to the receive antenna, for selectively delivering the at least one satellite signal to at least one receiver via an output of the module, wherein the module creates an association between the module and the at least one receiver upon installation of the at least one receiver to the output, such that the module delivers the at least one satellite signal to the at least one receiver only when the association is present.
Abstract:
Disclosed is a method for transmitting a notification message in a mobile broadcast system that includes transmitting common notification message channel information necessary for receiving a common notification message for all users capable of receiving broadcast services, along with an Electronic Service Guide (ESG) for the broadcast services or a control signal for the broadcast services; transmitting specific notification message channel information necessary for receiving a specific notification message for a specific user group to a terminal in the specific user group along with the ESG; generating at least one of the common notification message and the specific notification message; and transmitting the generated notification message to the terminal using the corresponding channel information.
Abstract:
Disclosed are a subscriber management system and a method thereof using OOB (Out Of Band) channel in the DMB (Digital Multimedia Broadcasting). The system of the invention transmits a message for the alteration of the subscriber information to terminal through the OOB, and receives the result of the transmitting of message, that the result comprises a success of the transmitting/alteration, a failure of the alteration, and an error of the transmitting. Therefore, the system is able to apply the alteration of subscriber information to the terminal as soon as the subscriber information is altered.
Abstract:
A method for addressing terminals for receiving television programs subject to charge includes dividing the terminals into respective groups, each group having a respective group address. A respective identifier is assigned to each of the terminals of a group, each identifier being a respective binary vector. A data word and the respective group address of a first group is sent so as to address predetermined terminals of the first group. The data word is generated by logically combining the respective binary vectors of the terminals of the first group with a further binary vector, the further binary vector indicating the predetermined terminals.
Abstract:
A system and method is provided to dynamically insert content into programming breaks of at least a first programming channel. In order to dynamically insert such content, status information regarding a current status of a programming channel is procured. Based on the status information, a plurality of available insertion options (e.g., assets) may be identified. Using the identified asset options, an asset insertion schedule is developed for least one subsequent programming break of the programming channel. Upon identifying the beginning of the at least one subsequent programming break, the selected assets may be inserted into a content stream (e.g., associated with the programming channel) according to the insertion schedule. Generally, to provide such dynamic insertion, the status of the programming channel may be monitored periodically and/or continuously such that assets that are suited for current network conditions may be selected and inserted into one or more programming breaks.
Abstract:
A method and system of distributing massive voiced publications to individual subscribers is described; The distribution system is constructed by: a transmission system including encoders, amplifiers, FM transmitters and other necessary equipments; some receiver devices; each receiver device has a unique identification number, a decoder and a saving unit that can automatically save the publications to a physical memory or a hard disk. The transmission system broadcasts massive voiced publications with identification numbers together; Amount of identification numbers of receiver devices can be up to millions or just one only; Receiver devices individually receive, decode and save the subscribed publications automatically.
Abstract:
An apparatus and a method for controlling an electric appliance using a broadcast wave are disclosed. Various electric appliances widely used in each household are so configured as to be equipped with a broadcast receiving module and receive a product-related additional data packet through the broadcast wave such as an FM multiplex broadcasting. The electric appliance controls its own operation according to information in the received additional data packet. Accordingly, the present invention enables the electric appliances to be remotely controlled by receiving the product control information packet transmitted through the broadcast wave. The present invention enables a natural disaster to be warned by receiving a disaster warning data packet transmitted through the broadcast wave. The present invention further enables guidance information on the electric appliance to be displayed by receiving the product guidance information packet transmitted through the broadcast wave.
Abstract:
The present invention concerns a server and a method for transferring a message originating in a telecommunication network to an addressed subscriber. A telecommunication terminal sends a message to a server. The server inserts an address allocated to a TV set of the address subscriber to the message or encrypts the message by means of an encryption key allocated to a TV set of the address subscriber. In the following, a headend node of a TV broadcast network inserts the message into a TV signal and broadcasts the TV signal via a TV broadcast channel. A receiver unit assigned to the TV set of the addressed subscriber filters out the message and outputs the message on the TV set.
Abstract:
A system and method of individualizing a general broadcast by combining a user identifier with a message and encoding the combination with a user specific code. Also, source identifiers can be added to the encoded combination, and the result again encoded and broadcast via a general broadcast system.
