With the evolution of the broadband market and the decline of the traditional voice services, telecom service providers need to offer a larger combination of services to maintain competitiveness and gain market share. Video and audio content are now available like never before. With the seamless delivery of voice, video and data services, Triple Play Services (3P) are essential for operators and service providers to retain their customer base. Video streaming applications require uninterrupted data transfer, but the smallest packet losses can result in great quality degradation. Moreover, delay and jitter can have crucial impact on the video delivery. This work tackles the Video Streaming impairments in different scenarios, such as noisy environments, concurrent background traffic and different distances from the customer and service provider. Variables related to the ADSL infrastructure, e.g. noise protection and QoS mechanisms, are observed and their adjustments are made in order to give improvements to the video quality. This work presents a desirable configuration for a real video transmission over ADSL systems in order to mitigate the existing problems.
