Abstract
Systems and methods to validate restriction event control streams sent to a video distribution system are provided. A particular method includes receiving a control stream from a content provider via a content proxy device. The control stream is associated with a restriction event and directs a media service delivery platform to associate a substitute service with a virtual network for at least one geographical region. The method also includes evaluating validity of the control stream based on content proxy information associated with the content proxy device.
Claims20
A method, comprising:
- receiving a control stream at a media service delivery platform, wherein the control stream is associated with a restriction event, and wherein the control stream directs the media service delivery platform to associate a substitute service with a virtual network for at least one geographical region;
- and
- checking that content proxy information and virtual network information of the control stream correspond to associated content proxy information and virtual network information in a mapping table of the media service delivery platform to validate the control stream, wherein a valid control stream is used to update a substitution table, and wherein at least a portion of the substitution table is sent to one or more video head ends to enable the video head ends to send access tables to one or more customer media devices.
A system, comprising:
- a processor;
- a non-transitory computer-readable storage media accessible to the processor, the non-transitory computer-readable storage media including instructions executable by the processor to:
- receive data that enables generation of a content proxy to virtual network mapping table that identifies at least one content proxy associated with one or more virtual network blocks;
- generate the content proxy to virtual network mapping table;
- receive control streams;
- access the content proxy to virtual network mapping table to validate the control streams, wherein at least one control stream is associated with a restriction event and wherein the at least one control stream comprises restriction event instructions and a content proxy identifier of a content proxy that received the at least one control stream from a content provider;
- update a substitution table with information from one or more valid control streams;
- and send at least a portion of the substitution table to one or more video head ends.
A non-transitory computer-readable storage medium, comprising:
- operational instructions that, when executed by a processor, cause the processor to receive a control stream associated with a restriction event;
- operational instructions that, when executed by the processor, cause the processor to compare content proxy information and virtual network information of the control stream with a content proxy and virtual network mapping table to evaluate whether the control stream is valid;
- operational instructions that, when executed by the processor, cause the processor to generate a substitution table when the control stream is identified as valid.
