Method for media stream processing and apparatus for implementing the same

A multimedia content packaging apparatus configured to process a media stream, the multimedia content packaging apparatus comprising:

• a memory;
• and
• a processor operatively coupled to the memory, the processor being configured to:
• obtain, based on media stream data received from a media encoder, at least one media data chunk of the media stream as a separately addressable media data object by a media data request received at the packaging apparatus, the at least one media data chunk being comprised in a media data fragment of the media stream,
• generate, based on the received media stream data, metadata related to the media data chunk, the metadata comprising
• information on the media data fragment to which the media data chunk belongs, and
• a timestamp for the media data chunk,
• store the media data chunk in a memory of the packaging apparatus in the form of a fragment file containing the media data chunk, based on the information on the media data fragment to which the media data chunk belongs indicating that the media data chunk is a first chunk of the media data fragment, the memory being configured to store media data chunks as separately addressable media data objects for a memory read from the memory,
• determine, based on the timestamp, whether the media data fragment was stored in the memory for a time period exceeding a predetermined duration,
• delete from the memory each of one or more media data chunks belonging to the media data fragment, based on the determining whether the media data fragment was stored in the memory for the time period exceeding the predetermined duration,
• update a list of media data chunks stored in the memory, based on the metadata related to the media data chunk, and
• update the list of media data chunks by deleting from the list metadata related to each of the one or more media data chunks belonging to the media data fragment.

A non-transitory computer-readable medium encoded with executable instructions which, when executed, causes a multimedia content packaging apparatus, equipped with a processor operatively coupled with a memory, to perform functions for processing a media stream, said functions comprising:

• obtaining, based on media stream data received from a media encoder, at least one media data chunk of the media stream, as a separately addressable media data object by a media data request received at the packaging apparatus, the at least one media data chunk being comprised in a media data fragment of the media stream;
• generating, based on the received media stream data, metadata related to the media data chunk, the metadata comprising
• information on the media data fragment to which the media data chunk belongs, and
• a timestamp for the media data chunk;
• storing the media data chunk in a memory of the packaging apparatus in the form of a fragment file containing the media data chunk, based on the information on the media data fragment to which the media data chunk belongs indicating that the media data chunk is a first chunk of the media data fragment, the memory being configured to store media data chunks as separately addressable media data objects for a memory read from the memory;
• determining, based on the timestamp, whether the media data fragment was stored in the memory for a time period exceeding a predetermined duration;
• deleting from the memory each of one or more media data chunks belonging to the media data fragment, based on the determining whether the media data fragment was stored in the memory for the time period exceeding the predetermined duration;
• updating a list of media data chunks stored in the memory, based on the metadata related to the media data chunk;
• and
• updating the list of media data chunks by deleting from the list metadata related to each of the one or more media data chunks belonging to the media data fragment.
