Abstract

A method and system for manipulating a manifest is disclosed. A server receives a smart appliance a request for a manifest corresponding to a session identifier. The server retrieves from a session server a session manifest based on the session identifier. The server adjusts a session offset based on a difference in a session length represented by the session manifest from a session length represented by a previous session manifest corresponding to the session. When the session manifest comprises an address of an ad break, the server identifies in a cache at least one advertisement to be inserted into the session and replaces at least one address corresponding to at least one segment of the at least one advertisement in the session manifest based on the difference. The server transmits the session manifest to the smart appliance.

Dependent claims

A method for manipulating a manifest, comprising:

storing, by the server, one or more manifests in a list of manifests in a memory, the one or more manifests differing in a number of segments corresponding to one or more advertisement breaks of different lengths;
receiving, by a server from a smart appliance, a request for a manifest having a first length of an advertisement break corresponding to a first number of segments corresponding to the advertisement break;
attempting to identify, by the server, a manifest having a substantially matching length to the first length of the advertisement break and having a matching number of segments to the first number of segments corresponding to the advertisement break in the list of one or more manifests stored in the memory;
when the server identifies a manifest in the list of the one or more manifests stored in the memory having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break,
retrieving, by the server, the identified manifest from the list of one or more manifests stored in the memory;
identifying, by the server, at least one advertisement to be inserted into an advertisement break of the identified manifest and replacing one or more addresses of segments in the identified manifest with one or more corresponding addresses of the at least one advertisement;
and
transmitting, by the server, the identified manifest to the smart appliance;
and
when the server does not identify a manifest in the list of the one or more manifests stored in the memory having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break,
generating, by the server, a manifest having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break;
inserting, by the server, the generated manifest in the list of the one or more manifests stored in the memory;
identifying, by the server, at least one advertisement to be inserted into an advertisement break of the generated manifest and replacing one or more addresses of segments in the generated manifest with one or more corresponding addresses of the at least one advertisement;
and
transmitting, by the server, the generated manifest to the smart appliance.

12 more elements

A computer system for manipulating a manifest, comprising:

a memory;
a processing device, coupled to and having access to the memory, the processing device to:
store, one or more manifests in a list of manifests in a memory, the one or more manifests differing in a number of segments corresponding to one or more advertisement breaks of different lengths;
receive, from a smart appliance, a request for a manifest having a first length of an advertisement break corresponding to a first number of segments corresponding to the advertisement break;
attempt to identify a manifest having a substantially matching length to the first length of the advertisement break and having a matching number of segments to the first number of segments corresponding to the advertisement break in the list of one or more manifests stored in the memory;
when the server identifies a manifest in the list of the one or more manifests stored in the memory having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break,
retrieve the identified manifest from the list of one or more manifests stored in the memory;
identify at least one advertisement to be inserted into an advertisement break of the identified manifest and replacing one or more addresses of segments in the identified manifest with one or more corresponding addresses of the at least one advertisement;
and
transmit the identified manifest to the smart appliance;
and
when the server does not identify a manifest in the list of the one or more manifests stored in the memory having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break,
generate a manifest having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break;
insert the generated manifest in the list of the one or more manifests stored in the memory;
identify at least one advertisement to be inserted into an advertisement break of the generated manifest and replacing one or more addresses of segments in the generated manifest with one or more corresponding addresses of the at least one advertisement;
and
transmit the generated manifest to the smart appliance.

14 more elements

A non-transitory computer readable storage medium including instructions that, when executed by a processing system, causes the processing system to perform operations, comprising:

storing, by the server, one or more manifests in a list of manifests in a memory, the one or more manifests differing in a number of segments corresponding to one or more advertisement breaks of different lengths;
receiving, by a server from a smart appliance, a request for a manifest having a first length of an advertisement break corresponding to a first number of segments corresponding to the advertisement break;
attempting to identify, by the server, a manifest having a substantially matching length to the first length of the advertisement break and having a matching number of segments to the first number of segments corresponding to the advertisement break in the list of one or more manifests stored in the memory;
when the server identifies a manifest in the list of the one or more manifests stored in the memory having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break,
retrieving, by the server, the identified manifest from the list of one or more manifests stored in the memory;
identifying, by the server, at least one advertisement to be inserted into an advertisement break of the identified manifest and replacing one or more addresses of segments in the identified manifest with one or more corresponding addresses of the at least one advertisement;
and
transmitting, by the server, the identified manifest to the smart appliance;
and
when the server does not identify a manifest in the list of the one or more manifests stored in the memory having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break,
generating, by the server, a manifest having the substantially matching length to the first length of the advertisement break and having the matching number of segments to the first number of segments corresponding to the advertisement break;
inserting, by the server, the generated manifest in the list of the one or more manifests stored in the memory;
identifying, by the server, at least one advertisement to be inserted into an advertisement break of the generated manifest and replacing one or more addresses of segments in the generated manifest with one or more corresponding addresses of the at least one advertisement;
and
transmitting, by the server, the generated manifest to the smart appliance.
