Abstract

We present an MPEG--7 compliant description of video sequences for scalable transmission and reconstruction. The proposed method is content-based and permits efficient and flexible video coding while keeping the benefits of textual descriptions in database applications. Video objects are described in terms of shape, color, texture and motion. These features are extracted automatically and are sufficient in a wide range of applications like smart video cameras and Universal Multimedia Access (UMA). Scalable sequence reconstruction is obtained by providing at least one quantitative as well as a qualitative descriptor for each feature; video objects are described by a subset of the proposed descriptors. The scalability and the compactness of the description are demonstrated in an outdoor application.

Advanced Video Coding

Advanced Video Coding (AVC), also referred to as H.264 or MPEG-4 Part 10, is a video compression standard based on block-oriented, motion-compensated coding. It is by far the most commonly used format for the recording, compression, and distribution of video content, used by 91% of video industry developers . It supports a maximum resolution of 8K UHD. The intent of the H.264/AVC project was to create a standard capable of providing good video quality at substantially lower bit rates than previous standards (i.

MPEG-1

MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical. Today, MPEG-1 has become the most widely compatible lossy audio/video format in the world, and is used in a large number of products and technologies.

MPEG-2

MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.
