“…Fixed nodes can be seen to possess larger upload bandwidth and higher computing power, with a larger viewing screen, more comprehensive multimedia player software, and large terminal with higher demand for multimedia quality. Fixed nodes in the system can be used as transcoding user nodes (i.e., it can convert the received multimedia data to a lower coding rate) [29][30][31][32][33][34][35]. In contrast, the mobile nodes mainly refer to wireless access equipment represented by mobile phone, Personal Digital Assistant (PDA), tablet PC, and other terminals.…”

With the development of wireless technologies, mobile communication applies more and more extensively in the various walks of life. The social network of both fixed and mobile users can be seen as networked agent system. At present, kinds of devices and access network technology are widely used. Different users in this networked agent system may need different coding rates multimedia data due to their heterogeneous demand. This paper proposes a distributed flow rate control algorithm to optimize multimedia data transmission of the networked agent system with the coexisting various coding rates. In this proposed algorithm, transmission path and upload bandwidth of different coding rate data between source node, fixed and mobile nodes are appropriately arranged and controlled. On the one hand, this algorithm can provide user nodes with differentiated coding rate data and corresponding flow rate. On the other hand, it makes the different coding rate data and user nodes networked, which realizes the sharing of upload bandwidth of user nodes which require different coding rate data. The study conducts mathematical modeling on the proposed algorithm and compares the system that adopts the proposed algorithm with the existing system based on the simulation experiment and mathematical analysis. The results show that the system that adopts the proposed algorithm achieves higher upload bandwidth utilization of user nodes and lower upload bandwidth consumption of source node.

“…Two examples are the videoconferencing over mobile networks and the DVB-H network which is currently under development and deployment (see [5] and references therein). However, real-time transcoding of compressed video streams is a growing need in a vast number of scenarios, including for instance the recent peer-to-peer networks, as highlighted in [6].…”

We are introducing a real-time variable frame rate control scheme capable of optimizing both spatial and temporal video qualities. It traces the motion of incoming video frames and automatically tunes the outgoing frame rate according to the level of jerkiness acceptable by the user. The control scheme was conceived within the framework of mobile communications, which require an optimum use of both the available bandwidth and terminal resources. We have designed and implemented a video transcoding architecture which supports our frame rate control. The transcoder has been developed at the Coritel laboratories, Rome, Italy (Coritel is a research consortium managed by Ericsson Lab, Italy, and the University of Rome La Sapienza), while the visual tests were carried out at the ISCOM laboratory, Italian Communication Ministry, Rome, Italy. The proposed transcoding architecture is compatible with the constraints of real-time communications and it has been extensively tested under a wide range of conditions. We then present a subjective assessment of our solution carried out in a fully equipped professional laboratory. Within this assessment a number of non-expert viewers were asked to express their preference when watching side by side the same video, coded at a variable frame rate and at a fixed frame rate. Results show that in most cases a variable frame rate control based on a dynamic bit/frame allocation scheme might substantially improve video quality perceived by viewers.

“…Nowadays, peer-to-peer (P2P) communication between wireless users in RoF access networks is increasingly useful due to the growth of applications such as multimedia communications, and voice and video over IP [6]. In these scenarios, the traffic from the source is sent to its nearest base station (BS), then sent to the BS close to the destination through the sub-network and finally delivered to the destination user.…”

Abstract-A novel peer-to-peer (P2P) interconnection architecture in a 60-GHz millimeter-wave (mm-wave) radio-over-fiber (RoF) access network is proposed for the first time. In this scheme, the beating of the lightwaves for downlink and P2P transmissions at the photodiode (PD) can provide signal up-conversion for both signals. Phase noise and frequency instability between the two independent lightwaves can be eliminated by a self-heterodyned radio frequency (RF) receiver (envelope detector) located on the user terminal, which can also downconvert simultaneously the two mm-wave signals to their associated intermediate frequencies. No high-frequency clock sources or other high bandwidth devices are required for signal up/down-conversions. A proof-of-concept experimental demonstration has also been carried out. Error-free transmission of the 1-Gb/ signals is achieved over 50-km fiber (downlink) or 25-km fiber (P2P) plus 4-m air link.
