Abstract

The invention discloses a non-interlaced voice data reading method and a non-interlaced voice data reading device and relates to the technical field of streaming media. The non-interlaced voice data reading method comprises the steps of intercepting original instructions for reading transport stream (TS) file data blocks; finding data pack information corresponding to video frame numbers in original files according to the video frame numbers in the original instructions; extracting video frame information required corresponding to the video frame number requirements according to the data pack information of the video frame numbers; generating minimum voice data reading instructions according to video frame information and reading video frame data according to the minimum voice data reading instructions; and using the video frame data as video data of the original instructions to be returned. Only the video data are read, other invalid data are not read, data reading amount is decreased greatly, and system resources are saved accordingly. Especially, a plurality of bandwidth resources are saved under the network environment, and system load is reduced.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a non-interleaved audio data reading method and device. Background technique [0002] With the rapid development of multimedia video services, the storage media of files is not limited to cassettes or CDs. TS (Transport Stream, which is suitable for wireless transmission, is a transport stream. TS streams are composed of many different types of packets. These data packets are 188 or 192 bytes in size. These bytes contain two parts, the header and the data load. The header includes synchronization information, packet information, etc., and the data load is the transmitted data, and these negatives can be Composition of data streams such as PES streams (Packetized Elementary Streams, packaged elementary streams) or private streams, because the above structure, when the transmission error destroys the synchronization information of a TS packet, the receiver can detect it in ...
