Abstract: A distributed video codec device using spatial reduction and enlargement, and a method thereof are provided to prevent degradation of a system with a reduced decoding computation quantity by receiving a time and space-reduced image. An image separator(211) temporally separates an input image. A first encoder transmits parity by encoding a part of the separated input image. A down-sampler(214) spatially reduces the rest of the separated input image. A second encoder encodes and transmits the reduced image.

Abstract: A method and an apparatus for an adaptive HTTP streaming service using metadata for content are disclosed. The metadata includes a minimum buffer time attribute indicating a minimum amount of initial buffered media content. A terminal receives the content from a server before reproducing the content and buffers at least the minimum amount of the content. The meta data includes a range attribute specifying the range of a target pointed to by a URL. The terminal receives bytes specified by the range attribute from the URL and reproduces the content using the received bytes. It is possible to specify the minimum amount of media initially buffered.
