Embodiment Construction

[0042] The following detailed description will introduce the apparatus and method for supporting various codecs according to the preferred embodiments of the present invention with reference to the accompanying drawings.

[0043] FIG. 2 is a schematic block diagram illustrating the structure of a video decoder for supporting multiple codecs according to a preferred embodiment of the present invention.

[0044]Referring to FIG. 2, a video decoder for supporting multiple codecs includes a header analysis unit 200, a switch 210, and a decoding unit (220a, 220b, 220n, hereinafter referred to as 220).

[0045] The header analysis unit 200 analyzes the header of the transmitted compressed bit stream and determines which decoder should be used. Then, the header analysis unit 200 sends a switch connection instruction corresponding to the determined decoder type to the switch 210 .

[0046] In response to the switch connection instruction sent from the header analysis unit 200, the sw...

Abstract

Different video codecs can be integrated or duplicated functions of each codec can be shared. According to an apparatus and method for supporting plural codecs of the present invention, a decoding process can be performed by analyzing information of a transmitted bit stream, deciding kind of codec being used by means of a header analysis unit, connecting through a switching unit to a corresponding decoder of a decoding unit including plural decoders or to a corresponding operation block among a plurality of operation blocks including at least one function.

Description

technical field [0001] The present invention relates to an apparatus and method for supporting multiple video codecs. Background technique [0002] The communication environment is currently changing rapidly to break down distinctions between wired and wireless coverage or national boundaries, and will do so in the future. In particular, the third-generation communication environment classified by IMT-2000 shows the trend in mobile communication today to provide users with not only images and voices but also information in various complex or real-time modes. [0003] The development of personal communication systems has also made it possible for cellular phones or PCS to extend services from voice communication alone to mobile text messaging, wireless Internet access, and the transmission of moving pictures commonly seen in TVs through personal communication terminals. [0004] This technology is a key element in digital TV systems and personal communication terminals using...
