This paper provides an overview of the transport mechanism of MPEG-2 as used as a part of the Digital Video Broadcasting standards. It is written as part of the Multimedia Systems course at Luleå University of Technology as well as a first insight into the BRaIN project’s main carrier technology focused upon. The paper will first present an overview of the broadcasting transport protocols using...

MPEG-2 is widely used as video coding standard for contents such as DVD or digital video broadcasting, DVB. It defines a layered structure, composing three different types of frames into groups for temporal and spatial compression of video information. In this paper we present an exhaustive analysis av various MPEG streams, taken from original DVDs. The purpose is to get a more clear picture ab...

We present a novel algorithm, architecture, and high-level Simulink prototyping for visible watermarking of MPEG-4 video streams. The watermark is inserted in the video stream during compression, resulting in an optimized compression/watermarking algorithm and system. Discrete Cosine Transform (DCT) watermarking, due to its robust nature, was chosen in this work to accomplish MPEG-4 video copyr...

The paper describes the work of the SatLabs Group in support of the DVBRCS standard, including a description of the main work areas.

Broadcasting can reduce the cost of video on demand services by distributing in a more efficient fashion videos that are simultaneously watched by many viewers. Rather than waiting for individual requests, broadcasting schedules repeated broadcasts of the various segments of a video ahead of time. Hence it performs best when it is used to distribute videos that are watched concurrently by hundr...
