摘　　要：针对数字电视的嵌入式浏览器在支持对广播数据的处理时,多采用与浏览器紧耦合的方式,会破坏浏览器原有的独立性和重复开发导致效率低下等问题,本文设计了一种嵌入式浏览器同时独立地支持互联网数据和广播数据的处理方法。该方法中设计了一种自定义的"cable"通信协议,通过该协议可以支持在互联网网页中实时下载访问广播数据,并且在数据广播网页中实时访问互联网数据。该方法在独立于浏览器内核之外的应用层快速支持对广播数据的下载和存储,与浏览器对标准的互联网数据处理完全独立,互不影响。实际应用表明,该方法设计结构清晰,数据处理高效,具有应用扩展强和开发周期短的特点。Embedded browser for digital television in support for processing broadcast data, using the close coupling mode with the browser usually, will undermine the independence of the browser and duplication of development will lead to low efficiency problems. This paper designed a processing method which embedded browser supports both Internet data and broadcast data independently. This method presents a communication protocol named ＂cable＂, through the protocol can support real - time access broadcast data in the In- ternet web page, and In broadcast data page can real - time access Internet data. This method can be independent of the browser out- side the kernel supports application downloading and saving broadcast data. The method with a standard Internet browser data process- ing is completely independent of each other. Practical application shows that this method is clearly structured design, and high efficien- cy data processing, and has a strong application extensions and short development cycle features.
