A novel method is proposed to achieve efficient MPEG-2 video editing in compressed domain while preserving Video Buffer Verifier (VBV) requirements. Different cases are determined, according to the VBV modes of the bitstreams to be concatenated. For each case, the minimum number of zero-stuffing bits or shortest waiting time between two streams is determined analytically, so that the resulting bit-stream is still VBV-compliant. The simulation:results show that the proposed method is applicable to any MPEG-2 bit-stream independent of its encoder.


Video segmentation using partially decoded MPEG bitstream
Kayaalp, Işıl Burcun; Akar, Gözde; Department of Electrical and Electronics Engineering (2003)
In this thesis, a mixed type video segmentation algorithm is implemented to find the scene cuts in MPEG compressed video data. The main aim is to have a computationally efficient algorithm for real time applications. Due to this reason partial decoding of the bitstream is used in segmentation. As a result of partial decoding, features such as bitrate, motion vector type, and DC images are implemented to find both continuous and discontinuous scene cuts on a MPEG-2 coded general TV broadcast data. The result...
Efficient and fair adaptive streaming: algorithm, implementation and evaluation
Öge, Ahmet; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2017)
HTTP Adaptive Streaming (HAS) is a popular video streaming method where the client downloads video segments over standard HTTP protocol. In HAS, the server stores the video segments that are encoded in different qualities which determine the video bit rates. To this end, the client first downloads a file which describes the video segments. Then, using a rate adaptation algorithm, the client decides on the most appropriate video bit rate for the next segment to download and sends an HTTP request for that seg...
HTTP http adaptive streaming architectures for video on demand and live TV services
Özcan, Yiğit; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2013)
HTTP Adaptive Streaming (HAS) has become a popular video streaming solution since it both benefits from the ubiquitous HTTP protocol and firewall and NAT traversal capabilities of TCP. HAS aims to provide high Quality of Experience (QoE) to the clients under limited and varying bandwidth by rate adaptation algorithms which allow the clients to choose the most appropriate video quality. A rate adaptation algorithm should utilize the available bandwidth. Furthermore, the received video bitrates should not dev...
Design of H.264/AVC compatible intra-frame video encoder on FPGA programmable logic devices /
Günay, Ömer; Kamışlı, Fatih; Department of Electrical and Electronics Engineering (2014)
Video compression is a technique used to reduce the amount of data in a video to limit the amount of storage space and bandwidth it requires. H.264/AVC is a widely used video compression standard developed together by the ISO (International Organization for Standardization) Moving Picture Experts Group (MPEG) and the ITU (International Telecommunication Union) Video Coding Experts Group (VCEG). H.264/AVC offers an extended range of algorithms for coding digital video to achieve superior compression efficien...
End-to-end stereoscopic video streaming with content-adaptive rate and format control
Aksay, Anil; Pehlivan, Selen; Akar, Gözde; Bilen, Cagdas; OZCELEBİ, Tanir; Civanlar, M. Reha; Tekalp, A. Murat (Elsevier BV, 2007-02-01)
We address efficient compression and real-time streaming of stereoscopic video over the current Internet. We first propose content-adaptive stereo video coding (CA-SC), where additional coding gain, over that can be achieved by exploiting only inter-view correlations, is targeted by clown-sampling one of the views spatially or temporally depending on the content, based on the well-known theory that the human visual system can perceive high frequencies in three-dimensional (3D) from the higher quality view. ...
