我们可以从几个方面来看一看机顶盒的发展趋势。 首先,在机顶盒的硬件平台上,会在几个方面有较大的发展:一是PC方式,CPU越来越强大;二是通用DSP方案,采用FPEG、CPLD可编程逻辑器件,例如软件STB产品,从介绍上看,有可能采用的是通用芯片方案,这样一来,标准与硬件上的限制因素少,便于实现应用软件的在线升级。同时存储器容量越来越大;MPEG解码器将支持同时解码多个HDTV的节目;图形功能越来越强大,将从简单的OSD发展到强大的2D、3D图形引擎;电缆调制解调器功能更加完善,以支持高速Internet接入和电子邮件,并将Web页面与视频有机地融合。
We can take a look at several aspects of the development trend of set-top boxes. First of all, in the set-top box hardware platform, there will be greater development in several ways: First, PC mode, CPU is more powerful; Second, the general DSP program, using FPEG, CPLD programmable logic devices, such as software STB products , From the introduction point of view, it is possible to adopt a general-purpose chip solution, this way, the standard and hardware limitations, easy to implement online application upgrades. While increasing memory capacity; MPEG decoder will support simultaneous decoding of multiple HDTV programs; graphics capabilities are more powerful, will be developed from a simple OSD powerful 2D, 3D graphics engine; cable modem functions more perfect to Supports high-speed Internet access and email, and organically integrates web pages with video.
