Problems solved by technology

But Android itself is mainly used in the field of mobile Internet, and the support for smart TV needs to be improved, especially the support of video streaming media player, live TV multicast support, and application development for TV. Android itself does not support IGMP multicast , and lack of good support in MPEG-2 TS over RTP

Embodiment Construction

[0098] The present invention carries out cross-platform transplantation by means of hardware abstraction. We deploy player instances on two different embedded devices, namely SMP8653 and MStar988. The SMP series are high-performance products released by media platform manufacturer Sigma Designs. set-top boxes, and the MStar988 platform is a Haier model card TV platform specifically for smart TVs. These two platforms are more representative on different hardware terminals. Table 2 shows the hardware configuration information of the two platforms.

[0101] 1. Realization of the abstraction layer of MStar TV platform

[0102] Since the MStar TV platform is based on the Linux operating system and directly provides device drivers for audio and video, the realization of the abstract interface on the platform can be completed by calling the driver operation in the user space, such as Figure 8 As...

Abstract

The invention discloses a general player applied to Android and Linux smart televisions. The general player is divided into three layers, namely an application interface layer, a data processing layer and a hardware abstraction layer. The application interface layer provides a unified media calling method for a streaming media application, and comprises a playing control interface, a parameter feedback interface and a service quality interface. Functions of data processing layer are mainly achieved by a media plug-in system, and the data processing layer comprises a receiving sub module, a packet analysis sub module, a demultiplexing sub module, a decoding sub module, an output sub module, etc. The hardware abstraction layer mainly comprises a hardware decoding link, an audio output link and a video output link, and upwards exists on a platform hardware adaptation layer in streaming media middleware in a local interface base mode. The general player applied to the Android and Linux smart televisions solves the problem of player compatibility, and can provide a streaming media playing function and a better service streaming media business.

Description

technical field [0001] The invention relates to a universal player for Android and Linux smart TVs; it provides an interface for upper-layer application developers in the form of a middleware module to shield the implementation details of the bottom layer, and at the same time meet the service quality and control requirements of streaming media . Background technique [0002] In modern society, in addition to traditional media such as newspapers and radio, and emerging media such as the Internet, television is one of the most important ways for people to obtain information. The development of TV is also changing with each passing day, along with the development of TV media from analog TV to digital TV. With the development of digital TV, smart TV has gradually entered enterprises and ordinary families. However, the current smart TVs are produced by different manufacturers, based on different TV chip solutions, using different embedded software, and there are also great di...
