Abstract

In one embodiment, a method, system and apparatus are described, for uniquely storing, in a memory, for each one user among a plurality of users which recorded a content item, at least one segment of the recorded content item, generating metadata at a metadata generator, the metadata generator configured to associate, for one user among the plurality of users, the at least one segment of the recorded content item recorded by the one user, the metadata including a bitmap uniquely identifying the one user, and determining, at a processor, for each one user of the plurality of users, at least one offset value indicating at least one starting point for the at least one segment of the recorded content item for the one user, the at least one segment of the one user being disposed in a media sequence including a plurality of segments of the content item for different users of the users that recorded the content item, the at least one offset value being determined based, at least, on the bitmap uniquely identifying the one user and a byte size of the at least one segment of the recorded content item. Related methods, systems and apparatuses are also described.

Claims19

Dependent claims

A system comprising:

a memory for storing executable program code;
and
a processor, functionally coupled to the memory, the processor being responsive to computer-executable instructions contained in the program code and operative to:
receive a first request to record a first segment of a media content from a first user, in response to receiving the first request, first metadata comprising a first bitmap array uniquely identifying the first user as a unique member of a first group of users among a plurality of groups of users;
determine, for the first user, a first offset value indicating a first starting point for the first segment, the first offset value being determined based, at least, on the first bitmap array uniquely identifying the one user and a byte size of the at least one segment of the recorded content item;
receive a second request to record the first segment of the media content from a second user;
generate, in response to the second request, second metadata for the first segment, the second metadata comprising a second bitmap array uniquely identifying the second user as another unique member of the first group of users;
create a segment metadata for the first segment, the segment metadata comprising a first group ID corresponding to the first group of users, a bitstring array comprising bits of the first bitmap array and the second bitmap array, and a bit count of the bitstring array;
and
create a write session for the first segment based on the bit count of the bitstring array.

A non-transitory computer readable storage medium comprising computer-executable instructions which, when executed by a computing device, will cause the computing device to perform a method comprising:

receiving from a first user a first request to record a first segment of a media content;
generating, in response to receiving the first request, first metadata for the first segment, the first metadata comprising a first bitmap array uniquely identifying the first user, as a unique member of a first group of users among a plurality of groups of users;
determining for the first user a first offset value indicating a first starting point for the first segment, the first offset value being determined based, at least, on the first bitmap array uniquely identifying the first user and a byte size of the first segment of the media content;
receiving a second request to record the first segment of the media content from a second user;
generating, in response to the second request, second metadata for the first segment, the second metadata comprising a second bitmap array uniquely identifying the second user as another unique member of the first group of users among the plurality of groups of users;
creating a segment metadata for the first segment, the segmented metadata comprising a first group ID, a first bitstring array comprising bits the first bitmap array and the second bitmap array, and a first bit count for the first bitstring array;
and
creating a write session for the first segment based on the bit count for the first bitstring array.
