Multimedia gateway multichannel data access method and multimedia gateway

Abstract

The invention belongs to the technical field of set top boxes and provides a multimedia gateway multichannel data access method and a multimedia gateway. The multimedia gateway multichannel data access method comprises the steps that descrambled transport stream data are stored in a corresponding cache data zone through a data storing thread established by a descrambling module, the data of the corresponding cache data zone are read through a data fetching thread established by a data distribution module, the read data are sent to a user, so that the data are stored and fetched in mutually independent processes and safety is improved. Meanwhile, the cache data zone is provided with a plurality of cache chips which are used for caching the descrambled transport stream data. Due to the fact that the descrambled transport stream data are cached through the cache chips of the cache data zone, the problems of video stream frame loss and frequency blocking are solved.

Description

technical field [0001] The invention belongs to the technical field of set-top boxes, and in particular relates to a multimedia gateway multi-channel data access method and a multimedia gateway. Background technique [0002] With the development of the integration of three networks, the existing charging model of one set-top box with one TV has increased the burden of families with multiple TVs. This model has been difficult to adapt to the needs of the society and the development of the market. The home multimedia gateway that came out also came into being. A multimedia gateway is a device capable of descrambling and distributing multi-channel digital TV programs. The family only needs to bear the viewing fee equivalent to a set-top box to watch programs on all TVs in the family. [0003] The current set-top box technology generally only supports 2-channel data processing. After the two-channel data is descrambled, one channel is pushed to the decoding device for display a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multimedia gateway multi-channel data access method in which the access data processes are independent of each other, aiming to solve the problem of low security when the existing set-top box realizes the multimedia gateway function

[0005] Further, another object of the present invention is to provide a multi-channel data access method of a multimedia gateway including storing data through multiple buffer slices, aiming at solving the problems of frame loss and Card frequency problem
