“…MPEG-4 was defined by the Moving Picture Experts Group (MPEG) [12] [14], which actively participates in the International Organization for Standardization (ISO), which specified the well known MPEG-1 and MPEG-2 standards. Hundreds of researchers worldwide contributed in the MPEG-4 building [15], which was concluded in 1998, just to become an international standard in 2000.…”

Abstract. The Internet has experienced a considerable increase in the use of audio and video applications, which provoke a large consumption of the resources available in the network and servers. Therefore, the monitoring and analysis of those resources has become an essential task in order to enhance the service delivered to users. This work depicts a monitoring module implemented in a video server architecture, which is used to track the transmission of some popular video formats. Our experiments have demonstrated that one of the formats delivers a performance considerably better than the other, regarding the bandwidth allocated to each user session, what reassures the importance of having such a monitoring module available in a server's architecture.

“…We recall that adapting codec quantization values is a CPU-intensive task which can affects the performance of the video server. The idea of quantizer scale was also used in the context of MPEG-4 in the work presented in [7]. This later employs Fine Granular Scalability which uses a layered coding algorithm.…”

Abstract.Video streaming over the Internet is a challenging task since the Internet is a shared environment offering only best effort service. That is, it offers no quality of service and no guarantee of resources in term of (1) bandwidth, (2) transfer delay, (3) delay variation (jitter), and (4) packet losses. Then, network stability and traffic fairness become critical issues. To solve these problems some source rate control and adaptation should be introduced for UDP traffic as well, in such a way that this traffic becomes TCP-compatible "TCP-friendly". In this article we propose an adaptive streaming framework for unicast MPEG-4 streams over TCP/IP networks. Based on Audio-Visual Content (AVOs) classification and network congestion feedback, video sources dynamically adds and drops MPEG-4 AVO to the streamed multiplex to conform to the TCP-Friendly Rate Control (TFRC) mechanism. Using a content classification model, TFRC automatically adjusts the number of AVOs to be streamed to adapt to network congestion while given much attention to the quality of the service perceived by the end-user. To achieve such a dynamic output rate and video quality adjustment, MPEG-4 AVOs are classified and multiplexed according to both application-level QoS parameters and AVOs semantic descriptors. AVOs requiring same QoS from the network are automatically classified and mapped to one of the available IP DiffServ PHB (Per Hop Behaviors). Performance evaluation shows that transmitted video gracefully adapts to network bandwidth variations while optimizing user perceived quality.

“…In this section, we briefly introduce (1) the FGS (Fine Granular Scalability) algorithm [5,6] which is excellent in adaptation to the bandwidth variation among MPEG-4 video-coding standards, (2) TFRC [3], which accomplishes fair-share of bandwidth among TCP and non-TCP connections, and (3) our FGS video rate control method proposed in [4].…”

“…To accomplish TCP-friendly video transfer with consideration of the application-level performance, i.e., video quality, we have considered the several issues such as control interval, video rate adjustment, and BL rate violation, in [4]. Then, we have proposed "G-G smooth" video rate adjustment method.…”

When a considerable amount of UDP traffic is injected into the Internet by distributed multimedia applications, the Internet is easily driven congested. Consequently, bandwidth available to TCP connections is oppressed and their performance significantly deteriorates. In order that both multimedia applications and TCP-based ones fairly co-exist in the Internet, it becomes increasingly important to consider the inter-protocol fairness.In this paper, we propose a video quality adjustment mechanism which accomplishes the high-quality, stable, and TCP-friendly video transfer under a lossy environment in cooperation with the FEC (Forward Error Correction) technique. Our mechanism adjusts the video quality in accordance with the TFRC (TCP-Friendly Rate Control) rate, the packet loss probability, and the resultant video quality. Through simulation experiments, we show that our proposed method can provide high-quality, stable and TCP-friendly video transfer even in the unstable and lossy Internet.
