A Primer To Video Transcoding: Image Transcoding
نویسنده
چکیده
In the video transcoding problem, we convert the video from one bit-rate to another which can help us design better streaming servers. This is achieved by changing the resolution as a trade-o for the bit-rate. In this work, we solve a part of the problem. The individual frames are represented in terms of 8 8 DCT blocks. We develop an algorithm for re-sampling the frame in the DCT domain, such that the reduced resolution video also has 8 8 DCT blocks. Our algorithm is for color images.

Video transcoding is a key technology to support video communications over heterogeneous networks. Although quite a bit of research effort has been made in video transcoding due to its wide applications, most video transcoding techniques proposed in the literature are optimized based on the simple Mean Squared Error (MSE) metric which does not correlate well with the human visual perception. In...
متن کاملA Hadoop-based Multimedia Transcoding System for Processing Social Media in the PaaS Platform of SMCCSE
Previously, we described a social media cloud computing service environment (SMCCSE). This SMCCSE supports the development of social networking services (SNSs) that include audio, image, and video formats. A social media cloud computing PaaS platform, a core component in a SMCCSE, processes large amounts of social media in a parallel and distributed manner for supporting a reliable SNS. Here, w...
متن کاملHomogeneous Video Transcoding of H.264/AVC Intra Coded Frames
The main goal of transcoding is to change bit rate of video sequence. This can be done by cascaded connection of decoder and encoder, known as Cascaded Pixel Domain Transcoder (CPDT). Decoding and re-encoding video bit stream always gives lower image quality than encoding original sequence. This paper presents a new technique of video transcoding that is able to deliver image quality superior t...
متن کاملSemantic Video Transcoding Using Classes of Relevance
In this work we present a framework for on-the-fly video transcoding that exploits computer vision-based techniques to adapt the Web access to the user requirements. The proposed transcoding approach aims at coping both with user bandwidth and resources capabilities, and with user interests in the video’s content. We propose an object-based semantic transcoding that, according to user-defined c...
متن کاملVideo Transcoding Gateway for Wireless Video Access
In this paper, we review several typical video transcoding architectures and major applications of video transcoding. We identify issues involved in access video streams through handheld devices and wireless networks. To handle these issues, we propose a video transcoding gateway system for intelligently transcoding pre-encoded video for different user devices and network connections. The main ...
