The method includes validating, by a processing device, the live media stream to ensure that the at least one manifest file, the playlists and the video chunks are available. Validating the live media stream includes determining whether the at least one live media stream complies with at least one predetermined standard. The method includes validating the live media stream to ensure that the files are not stale and live. The method also includes validating the live media stream to ensure that the video chunks are properly sequenced, and validating the live media stream based on Hypertext transfer protocol (HTTP) headers for the video chunks to determine whether errors are received associated with the live video stream. ## Claims ### Claim 1 A computing-device implemented method in a live stream validation client device, wherein the live stream validation client device includes a stream availability logic component, a stream sequencing and error logic component and a notification logic component, comprising: receiving, by the stream availability logic component, at least one manifest file, playlists and video chunks for at least one channel of at least one live media stream;

and alerting network personnel regarding detected issues based on the at least one live media stream failing compliance with the at least one predetermined standard. ### Claim 6 (depends on 1) The method of claim 1, further comprising: detecting a gateway timeout based on validation of the HTTP headers for the video chunks. ### Claim 7 (depends on 1) The method of claim 1, wherein the at least one channel comprises a plurality of channels, further comprising: identifying a same playlist across different clients for the plurality of channels associated with the live media stream; and performing a single validation test for the different clients for the plurality of channels associated with the live media stream. ### Claim 8 (depends on 1) The method of claim 1, further comprising: validating the at least one live media stream after a predetermined time based on a predetermined sampling format to check a health of a system associated with the at least one live media stream. ### Claim 9 (depends on 1) The method of claim 1, wherein the at least one channel comprises a plurality of channels, further comprising: decrypting a video associated with the at least one live media stream and displaying the video in a form of tiles for each of the plurality of channels. ### Claim 10 (depends on 1) The method of claim 1, further comprising: determining whether the at least one live media stream conforms to a particular format. ### Claim 11 (depends on 1) The method of claim 1, further comprising: examining the HTTP headers to determine parameters for the video chunks, wherein the parameters include a request time, and a last modified time. ### Claim 12 A live stream validation client device, wherein the live stream validation client device includes a stream availability logic component, a stream sequencing and error logic component and a notification logic component, comprising: a memory to store a plurality of instructions;
