BASE LINEAR STREAM CREATER FOR PERSONALIZED CHANNELS
A method is provided for establishing a personalized channel, with a request received to establish a personalized channel to be deliverable to a prescribed set of client devices as a linear channel streaming adaptive bit rate (ABR) video content. Responsive to the request, a base linear stream manifest is generated for the personalized channel. The base linear stream includes a first sequence of in-band signaling markers each representing at least one chunk of content. Each of the in-band signaling markers in the first sequence have an annotation representing a point of decision and specifying a network location of a decisioning engine that resolves the decision by specifying a content asset to be streamed at a specified time. The first sequence of in-band signaling markers spans a continuous duration of time without gaps over which ABR video content to be specified by the decisioning engines is to be inserted.
1 . A method for establishing a personalized channel, comprising:
receiving a request to establish a personalized channel that is to be deliverable to a prescribed set of client devices as a linear channel streaming adaptive bit rate (ABR) video content; and
responsive to the request, generating a base linear stream manifest for the personalized channel, the base linear stream including a first sequence of in-band signaling markers each representing at least one chunk of content, each of the in-band signaling markers in the first sequence having an annotation representing a point of decision and specifying a network location of a decisioning engine that resolves the decision by specifying a content asset to be streamed at a specified time, the first sequence of in-band signaling markers spanning a continuous duration of time without gaps over which ABR video content to be specified by the decisioning engines is to be inserted.
2 . The method of claim 1 , wherein the decisioning engines respectively specifying the content assets provide network locations at which the content assets are available.
3 . The method of claim 1 , wherein the base linear stream includes a second sequence of in-band signaling markers each representing at least one chunk of content, each of the in-band signaling markers in the second sequence having an annotation representing a point of decision and specifying a network location of a decisioning engine that resolves the decision by specifying a content asset to be inserted at a specified time, the second sequence of in-band signaling markers spanning a continuous duration of time without gaps over which ABR video content to be specified by the decisioning engines is to be inserted.
4 . The method of claim 1 , wherein at least one of the content assets is a video-on-demand (VOD) asset.
5 . The method of claim 3 , wherein at least one of the content assets is an advertisement asset.
6 . The method of claim 5 , wherein at least another of the content assets is a live event.
7 . The method of claim 1 , further comprising sending the base linear stream manifest to a video manifest manipulator for assembling a personalized channel manifest from the base linear stream manifest and delivering the personalized channel manifest to a prescribed set of client devices as a rolling manifest.
8 . The method of claim 1 , wherein base liner stream manifest represents a never-ending ABR video stream unless and until an external event causes termination of the ABR video stream.
9 . The method of claim 1 , wherein receiving the request includes receiving a schedule of live events and advertisements to be included on the personalized channel.
10 . The method of claim 7 , wherein sending the base linear stream manifest includes pacing out the base linear stream manifest in accordance with real-world clock time.
11 . The method of claim 1 , further comprising specifying a content asset to be streamed at a specified time in the event of a failure by a decisioning engine to resolve a decision.
12 . The method of claim 6 , further comprising specifying a content asset to be streamed at a specified time, the specified content asset serving as a transition into or out of the live event.
13 . A computer-readable medium having computer executable instructions for implementing a method comprising:
receiving a request to provide a base linear stream manifest for a personalized channel; and
responsive to the request, generating a base linear stream manifest for the personalized channel, the base linear stream including a first sequence of in-band signaling markers each representing at least one chunk of content, each of the in-band signaling markers in the first sequence having an annotation representing a point of decision and specifying a network location of a decisioning engine that resolves the decision by specifying a content asset to be streamed at a specified time, the first sequence of in-band signaling markers spanning a continuous duration of time without gaps over which ABR video content to be specified by the decisioning engines is to be inserted.
14 . The computer-readable medium of claim 13 , further comprising sending the base linear stream manifest to a video manifest manipulator that delivers an ABR manifest to ABR client devices, the ABR manifest being generated using the base linear stream manifest.
15 . The computer-readable medium of claim 13 , wherein at least one of the content assets is a VOD asset and another of the content assets is a live event.
16 . The computer-readable medium of claim 15 , wherein a system generating the base linear stream manifest includes the decision engine that resolves the decision to specify the live event.
17 . The computer-readable medium of claim 13 , wherein the decisioning engines respectively specifying the content assets provide network locations at which the content assets are available.
18 . The computer-readable medium of claim 13 , wherein the base linear stream includes a second sequence of in-band signaling markers each representing at least one chunk of content, each of the in-band signaling markers in the second sequence having an annotation representing a point of decision and specifying a network location of a decisioning engine that resolves the decision by specifying a content asset to be inserted at a specified time, the second sequence of in-band signaling markers spanning a continuous duration of time without gaps over which ABR video content to be specified by the decisioning engines is to be inserted.
19 . The computer-readable medium of claim 13 , wherein base liner stream manifest represents a never-ending ABR video stream unless and until an external event causes termination of the ABR video stream.
20 . The computer-readable medium of claim 13 , wherein the request to receive the base linear stream for the personalized channel includes a request that at least one of the content assets specified by at least one of the in-band signaling markers is a prescribed content asset based at least in part on an individual profile of at least one subscriber.
