This memo describes how to carry real time text conversation session contents in RTP packets. Text conversation session contents are specified in ITU-T Recommendation T.140. Two payload formats are described. One for transmitting text on a separate RTP session dedicated for the transmission of text, and one for transmitting audio and text data within one single RTP session. Hellstrom Expires Au...

This document describes an RTP payload format for efficient and flexible transporting of audio data encoded with the Adaptive TRansform Audio Coding (ATRAC) family of codecs. Recent enhancements to the ATRAC family of codecs support high-quality audio coding with multiple channels. The RTP payload format as presented in this document also includes support for data fragmentation, elementary redu...

In order to compete with terrestrial services, satellite systems for broadband access networks must maximise the useful capacity provided by each satellite. The High Throughput system has been carefully optimised in terms of capacity as part of an ESA R&D contract. This system provides Kaband links between approximately one hundred user beams and a network of gateway stations over a regional Eu...

In this paper, we consider the problem of controlling multiple quadrotor robots that cooperatively grasp and transport a payload in three dimensions. We model the quadrotors both individually and as a group rigidly attached to a payload. We propose individual robot control laws defined with respect to the payload that stabilize the payload along three-dimensional trajectories. We detail the des...

This paper proposes a high capacity reversible image watermarking scheme based on integer-to-integer wavelet transforms. The proposed scheme divides an input image into non-overlapping blocks and embeds a watermark into the high frequency wavelet coefficients of each block. The conditions to avoid both underflow and overflow in the spatial domain are derived for an arbitrary wavelet and block s...

High-precision collaborative observation is urgently needed due to the increasing demands of space science missions. Based on a conventional DFP (disturbance-free-payload) configuration, this paper presents novel that has great potential deal with The system developed, in which two or more payloads are installed via non-contact unit and parallel configuration. Thus, design multibody dynamics sy...
