SWITCHED MULTICAST VIDEO STREAMING
A system and method for improving media delivery and display. By utilizing a memory buffer in a DVR or similar device, and broadcasting linear content at a rate other than 1×, services like video on demand or regular broadcasters can be more versatile. For example viewers can start over without launching a separate VOD session. If part of the linear content requested is not in the buffer, a switched multicast stream can be sent to with the proper section of content. Other receivers on the network may also receive the stream and buffer the content if the content is related to what a viewer is viewing.

22 . A computer-implemented method, comprising:
receiving a request, from a user, to access media content that is in-progress;
based on receiving the request, causing the media content to be played from a particular timepoint of the media content that is after a beginning timepoint of the media content;
determining whether to permit playing of the media content from the beginning timepoint;
in response to determining to permit playing of the media content from the beginning timepoint, providing for display an indication that the media content is capable of being played from the beginning timepoint of the media content;
receiving input requesting to access the beginning timepoint of the media content; and
in response to receiving the input, causing the media content to be played from the beginning timepoint of the media content instead of the particular timepoint of the media content.
23 . The method of claim 22 , further comprising:
in response to determining not to permit playing of the media content from the beginning timepoint, declining to provide for display an indication that the media content is capable of being played from the beginning timepoint of the media content.
24 . The method of claim 22 , further comprising:
in response to determining not to permit playing of the media content from the beginning timepoint, providing for display an indication that the media content is not capable of being played from the beginning timepoint of the media content.
25 . The method of claim 22 , wherein determining whether to permit playing of the media content from the beginning timepoint of the media content comprises determining that a portion of the media content corresponding to the beginning timepoint of the media content has finished being downloaded.
26 . The method of claim 22 , further comprising:
prior to receiving the request to access the media content and playing the media content from the particular timepoint based on the received request, storing a portion of the media content corresponding to the beginning timepoint of the media content in a buffer memory or a cache memory; and
determining whether to permit playing of the media content from the beginning timepoint of the media content comprises determining that the portion of the media content corresponding to the beginning timepoint of the media content is stored in the buffer memory or the cache memory.
27 . The method of claim 26 , further comprising:
identifying viewing preferences of the user; and
storing the portion of the media content corresponding to the beginning timepoint of the media content in the buffer memory or the cache memory in response to determining that one or more attributes of the viewing preferences of the user match one or more preferences of the media content.
28 . The method of claim 26 , wherein:
the request to access the media content is received while different media content is being accessed; and
the method is further configured to, based on the different media content having been accessed within a threshold period of time from when the media content is accessed, storing in the cache memory or the buffer memory one or more portions of the different media content occurring while the media content is being accessed.
29 . The method of claim 22 , wherein receiving the input comprises receiving selection of the indication that the media content is capable of being played from the beginning timepoint of the media content.
30 . The method of claim 22 , further comprising:
determining that one or more portions of the media content, occurring after the beginning timepoint of the media content, are not yet available for playing; and
providing for display an indication of an amount of time remaining until each portion of the media content prior to the particular timepoint will be available for playing.
31 . The method of claim 22 , further comprising, in response to determining to permit playing of the media content from the beginning timepoint, providing an option to record the media content.
32 . A computer-implemented system, comprising:
computer memory;
control circuitry configured to:
receiving a request, from a user, to access media content that is in-progress, wherein a user profile of the user is stored in the computer memory;
based on receiving the request, cause the media content to be played from a particular timepoint of the media content that is after a beginning timepoint of the media content;
determine whether to permit playing of the media content from the beginning timepoint;
in response to determining to permit playing of the media content from the beginning timepoint, provide for display an indication that the media content is capable of being played from the beginning timepoint of the media content;
receive input requesting to access the beginning timepoint of the media content; and
in response to receiving the input, cause the media content to be played from the beginning timepoint of the media content instead of the particular timepoint of the media content.
33 . The system of claim 32 , wherein the control circuitry is further configured to:
in response to determining not to permit playing of the media content from the beginning timepoint, decline to provide for display an indication that the media content is capable of being played from the beginning timepoint of the media content.
34 . The system of claim 32 , wherein the control circuitry is further configured to:
in response to determining not to permit playing of the media content from the beginning timepoint, provide for display an indication that the media content is not capable of being played from the beginning timepoint of the media content.
35 . The system of claim 32 , wherein the control circuitry is further configured to determine whether to permit playing of the media content from the beginning timepoint of the media content by determining that a portion of the media content corresponding to the beginning timepoint of the media content has finished being downloaded.
36 . The system of claim 32 , wherein the control circuitry is further configured to:
prior to receiving the request to access the media content and playing the media content from the particular timepoint based on the received request, store a portion of the media content corresponding to the beginning timepoint of the media content in the computer memory comprising a buffer memory or a cache memory; and
determine whether to permit playing of the media content from the beginning timepoint of the media content comprises determining that the portion of the media content corresponding to the beginning timepoint of the media content is stored in the buffer memory or the cache memory.
37 . The system of claim 36 , wherein the control circuitry is further configured to:
identify viewing preferences of the user; and
store the portion of the media content corresponding to the beginning timepoint of the media content in the buffer memory or the cache memory in response to determining that one or more attributes of the viewing preferences of the user match one or more preferences of the media content.
38 . The system of claim 36 , wherein:
the request to access the media content is received while different media content is being accessed; and
the control circuitry is further configured to, based on the different media content having been accessed within a threshold period of time from when the media content is accessed, store in the cache memory or the buffer memory one or more portions of the different media content occurring while the media content is being accessed.
39 . The system of claim 32 , wherein receiving the input comprises receiving selection of the indication that the media content is capable of being played from the beginning timepoint of the media content.
40 . The system of claim 32 , wherein the control circuitry is further configured to:
determine that one or more portions of the media content, occurring after the beginning timepoint of the media content, are not yet available for playing; and
provide for display an indication of an amount of time remaining until each portion of the media content prior to the particular timepoint will be available for playing.
