A method of and an apparatus are provided for signaling a transmission code set in data broadcasting. A client using the transmission code set signaling method includes a demultiplexer demultiplexing a packetized elementary stream (PES) packet corresponding to a program selected by a user from the broadcasting stream received by the system interface, an image decoder decoding the demultiplexed PES for images, a sound decoder decoding the demultiplexed PES for sound, and a CPU fetching information about a transmission code set of a character string used in an object carousel message from the demultiplexed message PES and decoding the character string used in the object carousel message based on the fetched information about the transmission code set.

Method and apparatus for signaling transmission code set in data broadcasting

A method and apparatus for receiving digital broadcasting data. The method for receiving digital broadcasting data includes: extracting location information of second service data which already received first service data refers to, from the first service data; by analyzing the location information, determining whether the second service data is in-band service data transmitted through an in-band channel, or out-of-band service data transmitted through an out-of-band channel; and if the second service data is transmitted through an out-of-band channel, determining the location information as the program number of the second service data.

Method and apparatus for receiving broadcasting data

A client receiving a data stream via broadcasting is provided. The client includes a receiver which receives an object carousal that comprises data and a broadcast inter ORB protocol (BIOP) message, a processor which retrieves a transmission code set information from the BIOP message, wherein the transmission code set information provides an instruction to interpret character strings of the BIOP message, and a decoder which decodes the character strings based on the instruction provided by the transmission code set information.

A server supporting structures of objects represented in various languages in a broadcast data stream is provided. The server includes a generator which generates an object carousal that comprises data and a broadcast inter ORB protocol (BIOP) message; a processor which inserts transmission code set information into the BIOP message of the object carousel, wherein the transmission code set information provides an instruction to interpret character strings of the BIOP message; and a transmitter which transmits the object carousal.

A method is provided for transmission and reception, by an object carousel, of an object including data and a message to reference the data. The method includes inserting into the message information regarding an encoding system used to encode character strings within the message; transmitting the data and the message by the object carousel; receiving the data and the message; determining the information from the message; and decoding the character strings within the message according to the information, wherein the message is a broadcast inter ORB protocol (BIOP) message.

Provided is a system includes a transmitting device which transmits by an object carousel an object including a data and a message to reference the data, and a receiving device which receives the object, wherein the message is a broadcast inter ORB protocol (BIOP) message. The transmitting device includes a control unit which inserts into the message information regarding an encoding system used to encode character strings within the message, and a transmitting unit which transmits the object and the message. The receiving device includes a receiving unit which receives the object, and a control unit which decodes the character strings based on the information.

A method of decoding character strings within a message to reference data is provided. The method includes receiving the message to reference the data transmitted by an object carousel, wherein the message is a broadcast inter ORB protocol (BIOP) message, determining information regarding an encoding system used to encode the character strings within the message; and decoding the character strings according to the information which is determined.

A method is provided for transmitting an object including data and a message to reference the data by an object carousel. The method includes inserting information in the message, wherein the information indicates an encoding system used to encode character strings within the message; and broadcasting the data and the message by the object carousel, wherein the message is a broadcast inter ORB protocol (BIOP) message.
