Implementing Statistical Multiplexing in DVB-H
A novel technique for implementing statistical multiplexing (StatMux) of broadcast services over Digital Video Broadcasting for Handhelds (DVB-H) channels is proposed. DVB-H uses a time-sliced transmission scheme to reduce the power consumption used for radio reception part in DVB-H receivers. Due to the time-sliced transmission scheme, the implementation of known StatMux methods for DVB-H appl...
متن کاملNo-Reference H.264/AVC Statistical Multiplexing for DVB-RCS
Replacement of MPEG-2 by the H.264/AVC codec for satellite video services, including aggregated video for the DVB-RCS uplink, presents an opportunity to develop efficient statistical multiplexing. In this paper, a scheme is developed that effectively models the relationship between number of nonzero coefficients and video quality. The result is the ability to equalize video quality, reduce qual...
متن کاملA Study on the Optimal Implementation of Statistical Multiplexing in DVB Distribution Systems
The paper presents an overview of the main methods used to improve the efficiency of DVB systems, based on multiplexing, through a study on the impact of the multiplexing methods used in DVB, having as a final goal a better usage of the data capacity and the possibility to insert new services into the original DVB Transport Stream. This study revealed that not all DVB providers are using statis...
متن کاملStatistical Time-Frequency Multiplexing of HD Video Traffic in DVB-T2
Digital video broadcast-terrestrial 2 (DVB-T2) is the successor of DVB-T standard that allows a two-dimensional multiplexing of broadcast services in time and frequency domains. It introduces an optional time-frequency slicing (TFS) transmission scheme to increase the flexibility of service multiplexing. Utilizing statistical multiplexing (StatMux) in conjunction with TFS is expected to provide...
متن کاملStatistical Multiplexing
Twenty-first century communications will be dominated by intelligent high-speed information networks. Ubiquitous access to the network through wired and wireless technology, adaptable network systems, and broadband transmission capacities will enable networks to integrate and transmit media-rich services within specified standards of delivery. This vision has driven the standardization and evol...
