Description
Technical Field
The utility model relates to a file field of decoding, concretely relates to big file decoding equipment based on TS flows.
Background
The TS is a package format performed by a japanese high-definition camera, and is collectively called MPEG 2-TS. TS is an abbreviation for "TransportStream". The MPEG2-TS format is characterized by the requirement that it can be decoded independently from any segment of the video stream. When playing a TS file in a player, the TS file must be decoded first and then played, at present, the mainstream solution is to directly implant a TS format converter in the player, namely a format converter for coding or decoding the TS format, the TS format is a new high-definition packaging format, the TS format is decoded, namely the TS format is decoded and then coded into other formats, and common conversion modes of domestic common TS format converters, namely TS converter rmvb, TS converter mp4, TS converter avi and TS converter wmv, of the raccoon universal video converter are TS. Therefore, when playing a TS file, a waiting period is needed for decoding, and especially, decoding of a large file of a TS stream is often long, so that video playing needs to be waited and cannot be performed immediately after downloading.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a big file decoding equipment based on TS flows, as an external equipment, through the interface that corresponds and equipment connection, when the TS file download in-process, the segmentation decoding is accomplished in this equipment in the direct download, then directly plays through the player segmentation to accomplish to download promptly and put promptly.
The purpose of the utility model is realized through the following technical scheme:
a big file decoding device based on TS stream comprises a local main body, a USB data conversion connector and a transmission cable;
the main body of the machine is connected with a USB data conversion joint through a transmission cable, and the USB data conversion joint is connected with a playing device through a USB data line;
the main body of the machine is internally provided with a processor, a memory, a separator and a decoder, wherein the input end of the memory is provided with a data receiving/transmitting port which is connected with the USB data adapter, and the output end of the memory is connected with the processor;
the input end of the separator is connected with the processor, the output end of the separator is connected with the input end of the decoder, and the output end of the decoder is connected with the data receiving/transmitting port;
the processor is provided with an operation panel for realizing segmentation setting, memory data cleaning and decoding format selection of the separator.
In order to realize real-time playing, the TS file is selectively stored in the equipment of the scheme in the downloading process, decoding is completed in the equipment, and the file is directly stored in the player to be played after the decoding is completed, so that second-level playing is realized.
Furthermore, a control switch is arranged on the main body of the machine and used for controlling the start and stop of the equipment.
Furthermore, the decoder is internally provided with TS conversion rmvb decoding, TS conversion mp4 decoding, TS conversion avi decoding and TS conversion wmv decoding, and the decoding type is selected through the control panel. The user can select the decoding format according to the format supported by the player and the favorite of the user.
Further, the separator is used for identifying the file format in the memory, separating the video stream data and the audio stream data in the memory and sending the video stream data and the audio stream data to the decoder, and the separator adopts a separator provided in microsoft DirectX or a separator in an Elecard Player.
Furthermore, the two ends of the transmission cable, the main body of the computer and the connecting section of the USB data adapter are provided with anti-breaking structures.
Further, the data receiving/transmitting port is a full-duplex communication interface.
The utility model has the advantages that: the scheme utilizes the peripheral decoding equipment to decode the TS file, avoids decoding in the player during downloading, and the traditional player does not have a decoding function, so that the playing effect is not ideal during playing.
