Abstract
Network signals in a broadcast network can include ancillary data as well as audio and visual of a media presentation. Typically, the ancillary data is not displayed by the television when outputting the audio and visual data although it may be in some cases. To ensure the network signal is compatible with the components in the broadcast network, the embodiments herein test the network signal use an emulated version of the broadcast network. For example, the content provider can set up a local version of broadcast network using the hardware components of the broadcast network (e.g., a cable head end, network modulators, set top boxes, receivers, etc.). By transmitting the network signal through the emulated broadcast network, the content provider can verify that the ancillary data will be correctly transmitted through the actual broadcast network.
