后缀是{tvpi}的文件可以用什麽打开

A TVPI/TVVI file is an XML file that provides information about one or more television programs. The TVPI and TVVI formats are identical in format; they only differ in that a TVPI file is for future programming and a TVVI file is for in-progress programming. Developers can support the TVPI/TVVI file format by registering their application as the default handler for the TVPI file extension and the "application/x-tv-program-info" MIME type or the TVVI file extension and the “application/x-tv-viewer-info” MIME type. When a user requests a TVPI document, the browser launches the registered handler application, passing it the name of a temporary TVPI file. The application can then parse the TVPI file to get program start time, channel information, etc. The process for handling TVVI files is the same. PVR applications that support recording to multiple destinations (i.e., "Burn to DVD") can get the user’s choice by looking at the destination element.
