Other embodiments are disclosed. ## Claims ### Claim 1 A media player comprising: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: obtaining a manifest file for an adaptive bitrate media stream of media content, wherein the manifest file comprises: a uniform resource identifier identifying a chunk of the media content, a program change indicator identifying a program boundary between a first program and a second program within the chunk, and track information indicating durations of fragments of the chunk; receiving the chunk from a content delivery network, wherein the receiving the chunk is responsive to a request that is based on an available bandwidth associated with downloading data from the content delivery network; identifying the program boundary within the chunk based on detecting the program change indicator for the chunk; and displaying the chunk of the media content. ### Claim 2 (depends on 1) The media player of claim 1, wherein the operations further comprise determining whether to display a portion of the chunk after the program change indicator corresponding to the second program. ### Claim 3 (depends on 2) The media player of claim 2, wherein the determining is based on a restriction on the second program. ### Claim 4 (depends on 3) The media player of claim 3, wherein the operations further comprise blacking out a portion of the chunk after the program change indicator corresponding to the second program. ### Claim 5 (depends on 3) The media player of claim 3, wherein the operations further comprise switching to another stream after displaying a portion of the chunk before the program change indicator. ### Claim 6 (depends on 5) The media player of claim 5, wherein the another stream comprises a sponsored media or an advertisement. ### Claim 7 (depends on 3) The media player of claim 3, wherein the restriction is based on a parental controls of a program and wherein the operations further comprise blacking out the portion of the chunk after the program change indicator corresponding to the second program. ### Claim 8 (depends on 1) The media player of claim 1, wherein the program change indicator includes a timestamp that matches a scheduled time of the program boundary. ### Claim 9 (depends on 1) The media player of claim 1, wherein the media player comprises a cellular handset, a personal digital assistant, or a wireless networking device. ### Claim 10 A non-transitory, machine-readable storage medium, comprising executable instructions that, when executed by a processor of a media player, facilitate performance of operations, comprising: obtaining a manifest file for an adaptive bitrate media stream of media content, wherein the manifest file comprises: a uniform resource identifier identifying a chunk of the media content, a program change indicator identifying a program boundary between a first program and a second program within the chunk, and track information indicating durations of fragments of the chunk; receiving the chunk from a content delivery network, wherein the receiving the chunk is responsive to a request that is based on an available bandwidth associated with downloading data from the content delivery network; identifying the program boundary within the chunk based on detecting the program change indicator for the chunk; and displaying the chunk of the media content. ### Claim 11 (depends on 10) The non-transitory, machine-readable storage medium of claim 10, wherein the operations further comprise determining whether to display a portion of the chunk after the program change indicator corresponding to the second program. ### Claim 12 (depends on 11) The non-transitory, machine-readable storage medium of claim 11, wherein the determining is based on a restriction on the second program. ### Claim 13 (depends on 12) The non-transitory, machine-readable storage medium of claim 12, wherein the operations further comprise blacking out a portion of the chunk after the program change indicator corresponding to the second program. ### Claim 14 (depends on 12) The non-transitory, machine-readable storage medium of claim 12, wherein the operations further comprise switching to another stream after displaying a portion of the chunk before the program change indicator. ### Claim 15 (depends on 14) The non-transitory, machine-readable storage medium of claim 14, wherein the another stream comprises a sponsored media or an advertisement. ### Claim 16 (depends on 12) The non-transitory, machine-readable storage medium of claim 12, wherein the restriction is based on a parental controls of a program and wherein the operations further comprise blacking out the portion of the chunk after the program change indicator corresponding to the second program. ### Claim 17 (depends on 10) The non-transitory, machine-readable storage medium of claim 10, wherein the media player comprises a cellular handset, a personal digital assistant, or a wireless networking device, and wherein the processor comprises a plurality of processors operating in a distributed processing environment. ### Claim 18 A method comprising: obtaining, by a processing system including a processor, a manifest file for an adaptive bitrate media stream of media content, wherein the manifest file comprises: a uniform resource identifier identifying a chunk of the media content, a program change indicator identifying a program boundary between a first program and a second program within the chunk, and track information indicating durations of fragments of the chunk; receiving, by the processing system, the chunk from a content delivery network, wherein the receiving the chunk is responsive to a request that is based on an available bandwidth associated with downloading data from the content delivery network; identifying, by the processing system, the program boundary within the chunk based on detecting the program change indicator for the chunk; and displaying, by the processing system, the chunk of the media content. ### Claim 19 (depends on 18) The method of claim 18, further comprising determining, based on a restriction on the second program, whether to display a portion of the chunk after the program change indicator corresponding to the second program. ### Claim 20 (depends on 19) The method of claim 19, wherein the restriction is based on a parental controls of a program and wherein the method further comprises blacking out the portion of the chunk after the program change indicator corresponding to the second program.
