Abstract:
The present invention relates to a system for transmitting and receiving audio, particularly, to a method and apparatus for transmitting and receiving of object-based audio contents, which packetizes audio objects having the same characteristic. To achieve the above, the present invention includes filtering a plurality of ESs according to common information, adding a packet header to the respective filtered ESs and generate ES packets, aggregating all the generated ES packets and then adding a multi-object packet header to the aggregated ES packets to generate an object packet, and multiplexing the generated object packet, packetizing the multiplexed object packet according to a transmitting media and transmitting the packetized object packet.
Abstract:
An apparatus and a method for providing a Digital Multimedia Broadcasting (DMB) service using a digital TeleVision (TV) and an external device are provided. It is determined whether a received broadcast channel supports a Multi Mode Service (MMS), and if so, one of subchannels included in the broadcast channel is set to a main channel. The digital TV reproduces a broadcast signal via the main channel, and broadcast signals of subchannels excluding the main channel are transmitted to at least one external device in communication with the digital TV.
Abstract:
A device and method are provided for processing multimedia broadcast-related events in a portable terminal, and include a memory for storing character UI images according to multimedia broadcast-related events, an event collection section for collecting the multimedia broadcast-related events generated in the portable terminal and for generating event messages for discriminating the generated multimedia broadcast-related events, an agent control section including a plurality of specialists for processing the multimedia broadcast-related events, the agent control section determining specialists corresponding to the event messages, selecting and outputting character UI IDs corresponding to the multimedia broadcast-related events of the determined specialist, and processing feedback information on the corresponding events according to the feedback information of a user, and an agent expression section for outputting character images and texts which correspond to the multimedia broadcast-related events and the feedback information.

Das Verfahren weist ferner auf: Ermitteln (400) in welchen Blöcken (100) ein Nutzträgersignal (11) vorhanden ist und Ermitteln (500), nach Abschluss des Scannens (300) der Blöcke (100), für diejenigen Blöcke (111), für die ein Nutzträgersignal (11) ermittelt wurde, ob das jeweilige Nutzträgersignal (11) ein digitales Broadcasting Signal (12) ist. Ferner weist das Verfahren Ermitteln (600), für diejenigen Blöcke (112), für die ein digitales Broadcasting Signal (12) ermittelt wurde, zumindest einer weiteren in dem jeweiligen digitalen Broadcasting Signal (12) des jeweiligen Blockes (112) enthaltenen Information (1120) über die Nutzdaten (1121) des digitalen Broadcasting Signales (12) des jeweiligen Blockes (112) auf.
Abstract:
Provided are a method and apparatus for providing an Internet Protocol Datacasting (IPDC) service. The IPDC service providing apparatus includes a data input unit generating an IP packet and signaling information of the IP packet; a packet generation control unit determining a type of an Internet Protocol Data Group (IPDG) packet that is to be generated by encapsulating the IP packet, on the basis of characteristics of the IPDC service; an IPDG packet generation unit generating an IPDG packet according to a data type of the IP packet, and generating an IPDG packet for the signaling information of the IP packet; a transfer stream packet generation unit generating the IPDG packet as a transfer stream packet; and a transfer unit transmitting the transfer stream packet. Accordingly, it is possible to provide an IPDC service while efficiently using a bandwidth, in a Digital Audio Broadcasting (DAB) system.
Abstract:
A method for direct sampling of a plurality of radio bands, including a step of receiving a first radio band via a first interface and at least one additional radio band via at least one additional interface, the first radio band and the at least one additional radio band each being associated with different frequency ranges, and the first radio band or the at least one additional radio band being a DAB band. Furthermore, a selection signal is received via an interface, the selection signal indicating whether further processing of the first radio band and/or the at least one additional radio band takes place. Depending on the selection signal, the first radio band is sampled at a common sampling frequency and/or the at least one additional radio band is sampled at the common sampling frequency.
Abstract:
An apparatus for requesting black box images over a digital multimedia broadcasting (DMB) network, and an apparatus and method for searching black box images are disclosed. The apparatus for requesting black box images over a DMB network includes a request generation unit, an encoding unit, and a request transmission unit. The request generation unit generates information about a request for black box images to be collected. The encoding unit encodes the generated image request information into format suitable for transmission via a DMB data broadcast. The request transmission unit transmits the encoded image request information to apparatuses for searching black box images mounted on one or more vehicles through DMB broadcasting centers.
