A method, system, mobile device, apparatus and computer program product are provided for accurately determining whether one or more rights objects associated with a mobile device are valid. In particular, a secure time source (e.g., DRM clock or time) may be maintained by the mobile device and used to check the validity of the one or more rights objects. In order to ensure that the secure time source or clock remains accurate, the mobile device may update the secure time source by regularly requesting and receiving the DVB-H network time from a DVB-H network entity. Because the DVB-H network time is secure, accurate and readily accessible, it provides an ideal tool for correcting possible drift in the mobile device's secure time source.

A broadcast response system provides, e.g., a radio broadcast listener with the ability to obtain media content such as music or speech while listening to the radio. The user can respond to items in the radio broadcast such as advertisements, fund raising drives, or interactive listener polls during the broadcast. Data such as song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored, can be transmitted using, e.g., the RBDS/RDS data stream. A reference number representing song title and artist, author or publisher and the IP address for the location where the digital version of the content is stored can also be employed for ease of implementation. This reference number can reside in a lookup table to be accessed by broadcast response server.

Systems at a radio station provide representations to an acoustic fingerprinting service of audio content being broadcast for the provision of metadata identifying the audio content by the acoustic fingerprinting service back to the radio station for transmitting over the air or over the Internet simultaneously with the broadcast audio.

A radio broadcast playback method and apparatus is provided. The radio broadcast playback method includes playing a radio broadcast received by a tuner, receiving a channel search request, through an input unit, searching for radio channels by a communication module, while playing the radio broadcast received by the tuner, and outputting the found radio channels.

A distribution system for transmitting media content programs to premises equipment via a satellite transmission path addresses signal degradation caused by atmospheric conditions and other factors. Upon detection of a degradation of the satellite signal, the system may begin transmitting the content using an alternative signal path, such as a terrestrial IP network. The satellite transmission path is brought back on line after the satellite link is restored. Alternatively, the system may begin recording the signal in the media distribution system for transmission via the satellite link after the link is restored.

A server may receive a software update file image and determine that the software update is applicable to a predefined plurality of vehicles within an ATSC broadcast range, based characteristic of those vehicles compared to applicability requirements associated with the software update. Further, the server may instruct an ATSC transmitter to broadcast a file image of the software update, the broadcast including at least one parameter defining the characteristics of vehicles. The processor is also configured to receive feedback from one or more of the plurality of vehicles receiving the file image and responsive to the feedback, instruct adjustment of a broadcast characteristic to increase receipt of the broadcast file image among the plurality of vehicles.

A method for generating location-based advertisement includes receiving a selection of a first radio station from a user of a mobile device, receiving an electronic program guide from the first radio station including a plurality of advertisement time slots, where each advertisement time slot in the plurality of advertisement time slots includes an advertisement sequence for a first advertisement content, receiving a second advertisement content from a second radio station located in a geographic location matching a real-time geographic location of the user as determined by a location-based service of the mobile device, substituting the first advertisement content in the advertisement sequence of one of the plurality of advertisement time slots with the second advertisement content from the second radio station, and broadcasting the second advertisement content to the user via the mobile device.

A method and system for digital marketing and the provision of digital content allows a user to express, using an application executed on a computing device while a piece of content is being broadcast using an analog or digital signal by an analog or digital radio or television station system, an interest in the broadcast piece of content that is communicated to a backend system. The backend system selects an end point destination that is a pointer to further digital information associated with the broadcast piece of content and communicates the end point destination for the broadcast piece of content to the user who can access the digital information.

Provided are an apparatus and a method for processing conditional access system (CAS)-based content. A method of operating a broadcast receiving apparatus includes: receiving a broadcast stream that includes content encrypted based on a CAS; extracting, from the received broadcast stream, CAS information for decrypting the encrypted content; receiving an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator; and displaying the content decrypted based on the ECM.

Provided is a broadcast receiving device receiving a broadcast service interoperating with a companion device. The broadcast receiving device includes: an IP communication unit configured to establish a pairing session with the companion device; a broadcast communication unit configured to receive an emergency alert message including an emergency alert alerting a disaster situation on the basis of the broadcast service; and a control unit configured to transmit information on the emergency alert message to the companion device.
