Secure satellite-based content preloading

A method for protecting streaming media content over satellite-based communication, the method comprising:

• receiving, by a satellite content receiver comprising one or more processors and a non-transitory processor-readable medium, a first portion of streaming media content transmitted by a content security host system using multicast communication, wherein the first portion of the streaming media content comprises a plurality of P-frames, B-frames or both;
• storing, by the satellite content receiver, the first portion of the streaming media content at the non-transitory processor-readable medium;
• in response to a user command, accessing, by the satellite content receiver, the first portion of the streaming media content for output;
• identifying, by the satellite content receiver, a second portion of the streaming media content, wherein the second portion of the streaming media content comprises a plurality of I-frames necessary to reconstruct the plurality of P-frames, B-frames, or both received as part of the first portion via multicast communication;
• sending a request, by the satellite content receiver to the content security host system, that causes the second portion of the streaming media content to be transmitted to the satellite content receiver via unicast communication;
• receiving, by the satellite content receiver, the second portion of the streaming media content from the content security host system via unicast communication;
• combining, by the satellite content receiver, the first portion of the streaming media content and the second portion of the streaming media content to reconstruct the streaming media content for output such that the plurality of I-frames from the second portion of streaming media received via the unicast communication are used to decode the plurality of P-frames, B-frames, or both from the first portion of the streaming media content received via the multicast communication;
• and
• outputting, by the satellite content receiver, the streaming media content.
