摘要： Methods and apparatus are disclosed for identifying media and, more particularly, to methods and apparatus for decoding identifiers after broadcast. An example method includes a portion of an identifying code from a media signal, determine a partition of the look-up table based on the portion of the identifying code wherein the partition of the look-up table includes reference signatures associated with the portion of the identifying code, and identify the media signal by comparing a signature extracted from the media signal to reference signatures in the partition of the look-up table.

摘要： Implementations relate to methods and apparatus for the aggregation of guide and frequency map information for multiple frequency networks (MFNs) using an upper-level single frequency network (SFN). A mobile device can provide a program guide displaying a listing of content scheduled for broadcast by a content server. An upper network can be in hierarchical coverage with at least two networks, and can receive at least one of guide and frequency data associated with the program guide from the at least two networks. The upper network can aggregate the at least one of guide and frequency data into aggregated guide and frequency data. The aggregated data can be distributed to the at least two networks and/or accessed from the upper network. The mobile device can receive the aggregated data from either the at least two networks or the upper network.

摘要： An expanded television program delivery system is described which allows viewers to select television and audio program choices from a series of menus. The primary components of the system include an operations center, a digital cable headend, and at least one set top terminal having a remote control. The system allows for a great number of television signals to be transmitted by using digital compression techniques. A combined signal is transmitted over satellite to a cable headend, which may modify the combined signal for changes or additions in programming or menu content. The combined or modified signal is subsequently distributed to individual set top terminals in the cable network. Menus are partially stored in a set top terminal in each subscriber's home and may be reprogrammed by signals sent from the operations center or headend. Numerous types of menus may be used, incorporating information included within the video/data signal received by the set top terminal. A remote control unit with icon buttons allows a subscriber to select programs based upon a series of major menus, submenus, and during program menus. Various data gathering and analysis techniques are used to compile programs watched information that in turn is used in packaging programs, customizing menu selections, targeting advertisements, and maintaining account and billing information.

摘要： An arrangement for enhancing the process of extracting data from a broadband video digital data stream. The data structure specified in the standards is enhanced by the addition of a symbol table which translates between a symbolic name of a program and the corresponding program number of the program and the channel on which the program is being broadcast. Advantageously, any program may be broadcast over any channel and a symbolic naming convention which can be designed to avoid conflicts among independent designer groups can be utilized. The programs referred to above are either the entertainment programs such as motion pictures or software programs for controlling a set top terminal.

摘要： A monitoring apparatus for the use status of a car radio is disclosed. In addition to the function of identifying a radio station to which the car radio is tuned at any given time, the present apparatus is capable of identifying the individual actually in the driver's seat listening to that radio station, and of measuring the idle time during which the car radio could have been turned ON but actually was not. Also, the present apparatus has a rechargeable battery dedicated thereto, thereby to avoid overloading the vehicle-mounted storage battery used also for engine starter. Moreover, the present apparatus comprises a device for generating an excessive discharge alarm signal when the excessively discharged state of the rechargeable battery is detected. Furthermore, the present apparatus employs the radio station identification based on the detection of local oscillation frequency picked up at the tuner portion, which is in one to one correspondence with a radio station broadcast frequency.

摘要： The present invention provides greater capability and flexibility than existing cable headends. Specifically, the invention comprises a modular design for a cable headend and a combiner component for cable headend. The invention is particularly useful in cable television program delivery systems transponding large numbers of digitally compressed program signals. The combiner allows cherry-picking of programs from transponded signals.

摘要： Two additional structures for addition to the Digital Video Broadcasters (DVB) Service Information (SI) for implementation of the MPEG-2 Systems Standard (ISO/IEC 13818-1 are provided: the Logical Channel Table (LCT) and the Composite Channel Table (CCT). The LCT provides the mapping between a Logical Channel Number (LCN) representing a service and the transport stream/program number on which the service can be found. LCT entries may designate either simple conventional channels or Composite Channels. The LCT contains a Composite Channel Indicator (CCI), which when set to `1`, indicates that the selected channel is a composite channel. In this case, the LCT entry gives the home channel of the Composite Channel, which provides the CCT to the decoder so that the tuner can be retuned to the actual program designated in the CCT for current viewing. Each entry in the CCT associates a Composite Channel Number (CCN) with a LCN and represents the "present" definition for the composite channel. A simple LCN is used as a key to the LCT to determine the transport stream ID and program number for the service components in the usual way. As time progresses, the entry for a specific CCN will change; therefore, the CCN is used as a "pointer" to the LCN which is the currently active service for the composite channel. These tables work with conventional MPEG-2 service definitions to decode multi-service transport streams.
