With the increasing trend for Internet-capable mobile devices, such as smartphones and tablet PCs, users create an explosion of media streaming traffic. Even though the current cellular networks are barely able to provide such service in tolerable data rates, it leads to significant energy consumption. Therefore, in this paper, a cooperative method is proposed to minimize the energy consumption of...
Error Concealment is a very useful method to improve the video quality. It aims at using the maximum received video data to recover the lost information of the picture at the decoder. Lagrange interpolation algorithm is the most effective interpolation for error concealment while it lost some detail information. Hermite interpolation algorithm considers the change rate of the motion vector as well...
H.264 is well known for its excellent compression efficiency and the maximum temporal and spatial prediction. Thus, one packet loss even one bit error may cause destructive visible distortions due to error propagation effect. Besides, bit rates will always be scarce in wireless transmission environments. This paper focuses on the video transmission over high BER wireless network. We first use the...
Due to the growing interest in video delivery over unreliable channels, the problem of error concealment in video communication is increasingly important. Our goal is to enable the correct decoding of bitstream, on the top of that, have a maximum playable frame rate and video quality. To be able to better combat packet loss, this article proposes a UEP solution in data partitioned H.264 video. Using...
The portability and popularity of mobile devices make the access of Internet content become a common phenomenon. To support different mobile devices in the heterogeneous networking environments, digital content providers have to provide different versions of the multimedia streaming video for clients to choose.Traditional caching technology is not applicable to multimedia streaming proxy. Therefore,...
