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...
End-to-end learned image compression with normalizing flows for latent space enhancement Yavuz, Fatih; Kamışlı, Fatih; Department of Electrical and Electronics Engineering (2022-9) Learning based methods for image compression recently received considerable attention and demonstrated promising performance, surpassing many commonly used codecs. Architectures of learning based methodologies are typically comprised of a nonlinear analysis transform, which maps the input image to a latent representation, a synthesis transform that maps the quantized latent representation back to the image domain and a model for the probability distribution of the latent representation. Successful modelling...
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...
Lossless Image and Intra-Frame Compression With Integer-to-Integer DST Kamışlı, Fatih (2019-02-01) Video coding standards are primarily designed for efficient lossy compression, but it is also desirable to support efficient lossless compression within video coding standards using small modifications to the lossy coding architecture. A simple approach is to skip transform and quantization, and simply entropy code the prediction residual. However, this approach is inefficient at compression. A more efficient and popular approach is to skip transform and quantization but also process the residual block in s...
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...
