Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 126,842, filed March 2, 2015, entitled "Indication for Partial Segment," and filed August 13, 2015, entitled "Indication for Partial Segment" US Provisional Patent Application No. 62 / 204,505. The entire contents of both applications are incorporated herein by reference. Background technique [0003] During network transmission of digital files such as video segments or fragments sent in individual files called Partial file received. For example, current Evolved Multimedia Broadcast Multicast Service (eMBMS) middleware on a computing device may only receive a portion of a Dynamic Adaptive Streaming Hypertext Transfer Protocol (DASH) segment rather than the entire segment. In some cases, an application and / or client that provides input to a codec (such as a DASH client) can be enabled to recover and provide a portion of a file to the codec, even though the file m...
