Embodiment Construction

[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The main idea of ​​the scheme of the embodiment of the present invention is: obtain the TS packets of the recording file, merge the same TS packets according to the preset merging rules; compress the merged TS packets according to the preset compression algorithm, and complete the recording file compression, which solves the technical problem that the recording code stream corresponding to the existing file to be recorded is relatively large and inconvenient for storage and transmission.

[0036] The recording file compression method involved in the embodiment of the present invention is mainly applied to a TV set, and the TV set can be implemented in various ways. For example, a fixed terminal such as a smart TV, an LCD TV, or a curved TV.

[0037] In the subsequent description, the P TV set will be used as t...

Abstract

The invention discloses a recording file compression method, a TV set and a readable storage medium. By obtaining the TS packets of the recording files, the same TS packets are merged according to a preset merging rule; according to a preset compression algorithm, the merged The TS package is compressed to complete the compression of the recording file. The present invention utilizes the characteristics of TS packets, that is, the format of TS packets in recording files is fixed, and due to the limitation of TS packet capacity, recording files need to continuously use multiple TS packets with the same PID to transfer large blocks of data. By merging multiple identical PIDs and compressing the merged TS packets, efficient lossless compression is achieved, which not only significantly reduces the size of the recorded file, but also facilitates file storage and transmission, and the compression method is simple, easy to use, and easy to solve It solves the technical problem that the recording code stream corresponding to the existing file to be recorded is relatively large and inconvenient for storage and transmission.

Description

technical field [0001] The invention relates to the technical field of file recording and broadcasting, in particular to a recording file compression method, a television set and a readable storage medium. Background technique [0002] According to the ISOI3818 standard, the storage and transmission of files are realized through the transport stream TS stream (Transport Stream, TS, transport stream or code stream)) (188 bytes or other number of bytes, etc.) of the recorded file. The recorded file is generally recorded directly The complete TS package (Transport Stream Packet) corresponding to the file. However, with the improvement of the definition of recorded files, the popularity of high-definition recorded files is increasing, and the volume of recorded files corresponding to TS packages is getting larger and larger. For example, when recording 60 seconds of high-definition video, the corresponding recording stream exceeds 400Mbytes. Therefore, when the volume of the r...
