摘要:
According to the present invention, a transmission apparatus and method and a reception method and apparatus for providing a 3D service are disclosed. The transmission method for providing the 3D service while making a reference image transmitted in real-time interwork with an additional image transmitted separately from the reference image includes a real-time reference image stream generating step of generating a real-time reference image stream based on the reference image and transmitting the generated real-time reference image stream to a receiving side in real-time and an additional image transmitting step of transmitting the additional image providing the 3D service in interworking with the reference image to the receiving side separately from the reference image stream, wherein the real-time reference image stream includes a linkage information, which is information relating to the additional image to be interworking with the reference image and synchronization information for synchronization with the reference image and the additional image and content.

Provided are an apparatus and method for controlling program conversion according to program protection information. The method for controlling conversion of a broadcasting program includes: demultiplexing a broadcasting program into broadcasting program data and program protection information; encrypting the broadcasting program data based on distribution condition of the program protection information when recordation of the broadcasting program data is requested; and recording the encrypted broadcasting program data.

A video encoding method and apparatus are provided. The video encoding method includes determining whether a current block includes an affine-transformation object having an affine transformation; if the current block includes an affine-transformation object, generating a prediction block by performing affine transformation-based motion compensation on the current block in consideration of an affine transformation of the affine-transformation object; and if the current block does not include any affine-transformation object, generating a prediction block by performing motion vector-based motion compensation on the current block using a motion vector of the current block. Therefore, it is possible to achieve high video encoding/decoding efficiency even when a block to be encoded or decoded includes an affine transformation.

Provided are an apparatus and method of transmitting and receiving associated broadcasting contents based on a heterogeneous network. The transmission system generates a basic contents stream for basic contents configuring the broadcasting contents to transmit the basic contents stream to a terminal through a broadcasting network, generates an additional contents stream for additional contents associated with the basic contents to transmit the additional contents stream to the terminal through a communication network, and further transmits at least one of associated playing information on the basic contents and associated playing information on the additional contents to the terminal, and the reception terminal receives the basic contents stream, the additional contents stream, and the associated playing information and synchronize the basic contents and the additional contents with each other to play them, thereby playing the broadcasting contents in real time.

Provided is a Simple Aggregation Format (SAF) synchronization packet structure including a SAF synchronization packet header and a SAF synchronization packet payload and multiplexing diverse element streams which include a scene description elementary stream. The SAF synchronization packet header includes time information related to an access unit included in the SAF synchronization packet payload, and the SAF synchronization packet payload includes header information on the access unit and payload information indicating the access unit. Since the present invention can multiplex diverse elementary streams effectively and simply into one data stream, synchronized data transmission is possible. Since the present invention accommodates a synchronization layer packet of the MPEG-4 system, it can be easily integrated with the MPEG-4 system and utilize the advantage of the MPEG-4 synchronization layer packet such as the concept of an access unit or a degradation priority.

Disclosed are a master terminal capable of registering and managing terminals that belong to a personal use scope, which will be referred to as personally used terminals or personal use terminals, hereafter, and a method and system for managing personal use terminals by using the master terminal. The method for managing a personal use group using a first master terminal to register and manage terminals belonging to a personal use scope includes: requesting a second master terminal that belongs to the personal use scope for personal use group information; receiving the personal use group information from the second master terminal; and registering a terminal that belongs to the personal use scope as the personal use group based on the received personal use group information.
摘要:
Disclosed is a method and system for storing encryption key information and package key information for decrypting encrypted broadcasting programs to store broadcasting programs. The method for protecting broadcasting programs includes generating and storing information about a first encryption key for encrypting broadcasting programs, and generating package key information by encrypting the first encryption key using a second encryption key.
