Abstract
Official abstract text for this publication.
A method and apparatus for retrieving an I frame are disclosed in the present invention, wherein, the method includes: analyzing transport stream packets in a transport stream one by one, and if it is determined that the current transport stream packet is a video packet and includes a Packet Elementary Stream (PES) header, then making a determination according to data after the PES header in the current transport stream packet to locate initial and/or end locations of the I frame. In the present invention, without parsing syntax elements in H.264, such as a Sequence Parameter Set (SPS), a Picture Parameter Set (PPS), a slice etc., the location of the I frame can be positioned by simply comparing various Transport stream (TS) packets in the TS stream and making a determination.
First claim
Opening claim text (preview).
What we claim is: 1. A method for locating an I frames comprising: analyzing, by a server or a terminal, transport stream packets in a transport stream one by one, and when one of the transport stream packets is determined to be a video packet and it comprises a Packet Elementary Stream (PES) header, then said server or terminal determining a beginning position of the I frame or an ending position of the I frame based on data after the PES header in said one of the transport strea…
