  • Patent number: 8997162
    Abstract: A video on demand system has a video server (200) for outputting video streams requested by users, via a core network (620) and access networks (630, 640, 650). A resource manager (600) determines occupation information concerning how much of the previously allocated capacity is occupied by previously authorized video streams is determined before authorizing transmitting a new requested video stream. By checking there is sufficient core network capacity, a risk of disrupting existing video streams or causing other problems by overloading the allocated capacity, is reduced or avoided. Thus less capacity in the core network is needed, and so costs of such capacity can be reduced and there is increased confidence that demand peaks will be handled more gracefully. By checking without obtaining occupation information from the core network, the system can be more independent of the core network, to reduce costs of a real time interface to the core network.

  • Patent number: 8863206
    Abstract: A content provider computing device that transmits content to receivers at scheduled air times receives information regarding conditions relating to the transmissions. The computing device also receives data regarding content that a receiver will record. The computing device evaluates the information and compares it with the data to determine that there is a risk of interrupted transmission. As a result, the computing device transmits the content to the receiver prior to the scheduled air time. The conditions may include weather conditions, power outage conditions, and/or any other conditions that may affect transmission. In various implementations, the computing device may include content controls prior to transmission that prevent the content from being accessed prior to specified times. In some cases, the content control may prevent all access. In other cases, the content control may prevent some kinds of access to the instance of content prior to particular times and allow others.
