Spontaneity and Delay Considerations in Distributed TV Productions
نویسندگان
چکیده
During the online edition of video material for television over data networks a major concern is the accumulation of delay over the production chain. Before a video signal of a camera arrives at a remote studio to be edited live, it travels over video adapters and analog/digital converters to codecs which in turn compress the signal to comply with small bandwidth constraints. This technical process adds a significant amount of delay that makes it difficult for the camera crew and director to interact spontaneously. An additional amount of delay is added through their human reaction times as well. Meaningful interaction requires however, that the overall delay times stay within tight limits.

Effective Design of a 3×4 Two Dimensional Distributed Amplifier Based on Gate Line Considerations
In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...
متن کاملStabilization of a Type III Thermoelastic Bresse System with Distributed Delay-time
In this paper, we investigate a Bresse-type system of thermoelasticity of type III in the presence of a distributed delay. We prove the well-posedness of the problem. Furthermore, an exponential stability result will be shown without the usual assumption on the wave speeds. To achieve our goals, we make use of the semigroup method and the energy method.
متن کاملAutomatic Music Detection in Television Productions
This paper presents methods for the automatic detection of music within audio streams, in the foreor background. The problem occurs in the context of a real-world application, namely, the analysis of TV productions w.r.t. the use of music. In contrast to plain speech/music discrimination, the problem of detecting music in TV productions is extremely difficult, since music is often used to accen...
متن کاملGLOBAL ROBUST STABILITY CRITERIA FOR T-S FUZZY SYSTEMS WITH DISTRIBUTED DELAYS AND TIME DELAY IN THE LEAKAGE TERM
The paper is concerned with robust stability criteria for Takagi- Sugeno (T-S) fuzzy systems with distributed delays and time delay in the leakage term. By exploiting a model transformation, the system is converted to one of the neutral delay system. Global robust stability result is proposed by a new Lyapunov-Krasovskii functional which takes into account the range of delay and by making use o...
متن کاملNew Robust Stability Criteria for Uncertain Neutral Time-Delay Systems With Discrete and Distributed Delays
In this study, delay-dependent robust stability problem is investigated for uncertain neutral systems with discrete and distributed delays. By constructing an augmented Lyapunov-Krasovskii functional involving triple integral terms and taking into account the relationships between the different delays, new less conservative stability and robust stability criteria are established first using the...
