    摘要: A method and apparatus for changing codecs to reproduce video and/or audio data streams are provided. The method and apparatus are capable of seamlessly reproducing video and/or audio data streams encoded with two or more different codecs when a change of codecs occurs by determining in advance the start position of a program element at which a change of codecs occurs among video and/or data streams stored in buffers using information regarding a change of codecs included in a data packet and changing the codec used for decoding at the moment when the program element at which the change of codec occurs is first decoded.

    摘要: 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.

    摘要: A method of hierarchical image indexing which extracts representative images of a TV program and generates a hierarchical index image guide of the representative images, and an apparatus therefor. Respective images at predetermined times are extracted from a predetermined program. A hierarchical index is allocated to each extracted image and the indexes are mapped to locations of transport stream packets. A tree of images having the allocated indexes is constructed as a hierarchically indexed Image guide (HIIG). When a stored program is to be reproduced, a location desired to be watched is selected in the HIIG, and from the selected location, reproducing and trick plays (FF, rewind) are enabled such that a user easily searches the program and begins viewing the program at the searched for location.

    摘要: A video apparatus having a personal video recorder (PVR) function and a control method thereof are provided. The video apparatus includes a counter which assigns a timestamp to a transport stream packet, a synchronization unit which extracts time information from the transport stream packet, compares the extracted time information with system time information of the video apparatus, and outputs synchronization control information, and a controller which stores an information table created using the timestamp and synchronization control information.
