摘要:
In a broadcast receiving apparatus and a channel changing method in a broadcast receiving apparatus, broadcast data corresponding to a selected broadcast program, included in a channel broadcast signal received as a result of broadcast program selection, is descrambled based on previously stored descrambling control information, thereby shortening scrambling time and reducing channel change time in the broadcast receiving apparatus.

Provided are a DMB system for reducing a working load of a DMB receiving terminal, a method of transmitting PSI/SI version information, and a method of parsing PSI/SI. When PSI/SI is generated, a DMB station receives version information of the PSI/SI from each of PSI/SI generators, generates PSI/SI version information, and transmits the generated PSI/SI version information through a specific channel. Then, the DMB receiving terminal receives the PSI/SI version information, compares the received PSI/SI version information to stored PSI/SI version information, and parses received PSI/SI according to the comparison result. Accordingly, by controlling the DMB receiving terminal to parse PSI/SI only if the PSI/SI has been modified, an unnecessary working load due to the parsing can be reduced.

It is a finding of the present invention that a user of a broadcast receiver gets text information significantly more quickly if a reference to another text information object in the broadcasting signal is contained in a text information object included in the broadcasting signal, which is currently displayed on the display of the broadcast receiver, and the user is enabled to cause the text information to be displayed to be changed from the text information of the current text information object to the text information of the text information object to which the current text information object refers by simple operation of a user selection means. Here, the additional effort is very limited since in today's broadcast receivers there mostly is an “unoccupied” key, which only has an assigned function and thus is occupied in special situations of use of the broadcast receiver, and may be used as user selection means, as far as that goes. Due to the strong limitation of the available bandwidths of common broadcasting systems for data services, codings as efficient as possible are used in the generation of the text information objects to be transmitted.

A method and apparatus for transport encoded asset data and content data, multiplexing the transport encoded content data with a plurality of NULL transport packets to provide “place holder” for the asset data transport packets, and replacing the NULL transport packets with asset data transport packets prior to transmitting the multiplexed transport stream to a set top box.
摘要:
A receiver contains a demodulator system that can derive an analog audio signal and compressed digital data from radio frequency signal. The receiver also contains a decompressor that can decompress the compressed digital data into uncompressed form. A digital to analog converter is used to convert the uncompressed digital data into another analog signal. Control logic is used to allow a user to select either the demodulated analog audio signal or the converted analog signal. The selected signal is delivered to an output device, such as a loudspeaker.

These and other objects of the invention are provided by a method and system for real time display of time sensitive information. In a method of the invention, a first set of time sensitive information is received. A second set of information from the first set of time sensitive information is selected. The second set of information corresponds to a stored set of information identifiers. The second set of information is then stored. The second set of information is then displayed to a subscriber. In other embodiments of the invention, the time sensitive information includes stock quote information, news information, traffic information, or sports scores. The present invention can be implemented in a broadcast communication system such as a broadband communication system, wireless local loop or other communication system capable of broadcasting digital information.
摘要:
A method for acquiring and storing schedule event information in an interactive television system. The schedule event information includes events and a start time and date for each of the events. The method includes creating a window defined by a start time and date and an end time and date and receiving the schedule event information at a receiving station. The schedule event information is stored for events having a start time and date within the window. The method further includes automatically moving the window forward relative to the start time and date at a specified interval such that the end time and date of the window are always after a current time and date. A system for acquiring and storing schedule event information is also disclosed.
摘要:
A system and method for distributing audio information is disclosed. The system comprises a receiver, a server, and a communication network. The receiver allows a user to select and receive audio information that is stored at a location remote to the user. The server stores data and network addresses of programs that are available to the user. The communication network facilitates communication between the receiver, the server, and other devices attached to the network. The server or a network source may transmit audio data to the receiver that contemporaneously receives and plays the data for the user.

Program data is provided in association with a main audio program to a receiver of a duplicative radio broadcasting system wherein a duplicative broadcast (such as a hybrid IBOC broadcast) includes a primary channel and a backup channel in a predetermined frequency allocation. Both the primary channel and the backup channel transmit the main audio program, and the primary channel transmits program data not included in the backup channel. The receiver includes an audio output for reproducing the main audio program and a display for displaying the program data. The method includes recurrently compiling a program event list of the program data corresponding to a current program event and a plurality of upcoming program events. The program event list is recurrently transmitted within the primary channel. The receiver recurrently recovers the program event list and stores the program data in a memory. The program data of the current program event is displayed. The audio output is blended from the primary channel to the backup channel in response to detection of an impaired primary channel. The display is updated to show program data of one of the upcoming program events from the memory during impairment of said program data in said primary channel.
摘要:
A system for transmitting digital data to an active desktop of a user with push pull functionality, the system comprising a digital data transmitter operative to transmit the digital data to the active desktop in blocks which are sequentially transmitted to the active desktop, each block being an incomplete collection of data and being viewable even when less than all of the blocks have been received, receipt of subsequent blocks by the receiver serving to cumulatively improve the quality of the digital data received by the receiver, at least one but not all of the blocks being transmitted to the active desktop in a push manner, and at least one of the remaining blocks being transmitted to the active desktop in a pull manner, when specifically actuated by the user. A method is also described and claimed.
