Video processing incorporates subsystems for content acquisition or ingest from studios, satellites or alternative sources, to transcoding, storage and further to distribution to client devices.
In order to reach the desired latency or quality of the signal, the TV service operators should select the optimum way of how the video sources are brought into the headend. YesNet can help in selecting and delivering the best components, including the network infrastructure.
Video signals, from content providers or broadcasters, usually materialize in high bitrate and resolution, which is cannot be applied to the specific setup of the operator. Therefore, a proper signal transcoding should be initiated in order to meet the requirements of the end-user client devices and last mile bandwidth limitations.
The main differentiator of the interactive TV system compared to a classical broadcast is the ability to interrupt the live channel and go back in time. The origin acts as a distribution source of live and on-demand content and provides the storage capacity for catch-up and nPVR services.
Selecting the appropriate video delivery architecture is a challenging task as it has a direct impact on the operating costs of the operator. Noteworthy, private or public CDNs, they all have their advantages and disadvantages.
