A display apparatus is provided. The display apparatus includes a receiver configured to receive transmission streams and output a first number of transmission stream signals; a first signal processor configured to receive the first number of transmission stream signals in parallel, group the received transmission stream signals according to kinds thereof, and output a second number of transmission stream signals, the second number being less than the first number; a second signal processor configured to receive the second number of transmission stream signals output from the first signal processor, restore the received transmission stream signals into the first number of transmission stream signals, and form output data using the restored transmission stream signals; and an output configured to output the output data formed in the second signal processor.

Signal processing apparatus, display apparatus having the same, and signal processing method

A picture search method and apparatus for digital reproduction are provided. The picture search method includes, generating a multiple image screen by configuring one or more pictures provided before a reproduction start time selected by a user during a high-speed search to a screen or a plurality of screens, outputting the multiple image screen, and sequentially reproducing following pictures starting from a picture selected by the user among one or more pictures included in the output multiple image screen. Therefore, it is possible to allow a user to exactly select a desired reproduction start time during the high-speed search.

Provided is a method and apparatus for displaying video data without a display delay. In the method, a code indicating an end of stream is appended so that the code is appended behind a last video stream included in a stream to be displayed when only a part of an input stream including one or more video streams is displayed. In addition, the last video stream is displayed which is appended with the code indicating an end of stream.

Method and apparatus for displaying video data

A method, medium, and apparatus for deleting and/or restoring time-series contents stored in a recording medium. When the time-series contents are stored in the recording medium, deleting of data that is present in a first area of a recording medium includes periodically inserting a time stamp into the contents, generating deletion data positional information based on the time stamp, the deletion data positional information representing a relative position of the deletion data within the contents, storing the deletion data positional information and the deletion data in a second area of the recording medium, and designating the first area as overwritable on the recording medium. Even if the recording medium is reloaded in another disk drive and under another operating system, data deleted from the recording medium can be easily restored.

Provided is a method of booting an electronic device including a host central processing unit (CPU) and a security module. The method includes: the host CPU starting to boot a system by using boot information in response to a reset or power on event of the electronic device; and when an authentication start instruction is not received by the security module from the host CPU until a first predetermined period elapses after an occurrence of the reset or power on event of the electronic device, controlling an operation of the host CPU by the security module. According to the method, when the authentication start instruction is received before the first predetermined period elapses, the security module authenticates the boot information and controls the operation of the host CPU based on an authentication result. A method of authenticating a boot of the electronic device in the security module is also provided.

A method of formatting a digital broadcast transport stream packet, a digital broadcast transmitter, and a signal processing method thereof, includes constructing a transport stream packet that includes a stuffing region for an insertion of a known supplementary reference signal (SRS) data therein, randomizing the packet that includes the stuffing region is randomized, and the SRS data is inserted into the stuffing region of the randomized packet. Adding a parity for an error correction to the packet into which the SRS data has been inserted, the packet to which the parity has been added is interleaved, and a trellis encoding of the interleaved packet is performed. Inserting a segment sync signal and a field sync signal into the trellis-encoded packet, and a vestigial side band (VSB) modulation and an RF conversion of the packet are performed to transmit the VSB-modulated and RF-converted packet.

A broadcast receiving apparatus and a method for providing user information are provided. The broadcast receiving apparatus transmits user information stored in a storage medium to a broadcast station. Therefore, a user may participate in data broadcasting more conveniently.

Method for providing user information and broadcast receiving apparatus using the same

An apparatus, method, and medium for video synchronization are provided. The apparatus may include a PTS register storing a presentation time stamp (PTS) of a picture to be reproduced and skip enable flag information indicating whether the picture can be skipped, by using a position of the picture in a video decoder buffer in which pictures to be decoded are stored; and a controller controlling the picture reproduction by skipping, repeating, or reproducing the picture with reference to the PTS and the skip enable flag information stored in the PTS register.

Apparatus, method, and medium for video synchronization

A multi-program multiplexing/demultiplexing method and apparatus for preventing MPEG jitters from being generated in a digital broadcast, and a multi-program receiver using the multi-program multiplexing/demultiplexing apparatus are provided. The multi-program multiplexing method comprises: extracting a plurality of transport stream packets from a plurality of channel decoders; comparing a reference clock value of each transport stream packet with a system clock value latched by the reference clock value, and generating a system clock control value; inserting the system clock value into a local packet of each channel; and multiplexing a plurality of local packets of a plurality of channels and generating a multi-program packet.

Method and apparatus for multiplexing/demultiplexing multi-programs

Provided are a method and apparatus for encoding/decoding video data. The video data decoding method includes decoding a first video stream to generate 2D video data for two-dimensionally displaying video content and decoding a second video stream to generate 3D video data for three-dimensionally displaying at least one part of the display section of the video content.
