as browsing, deleting programs and rewriting the bespoken recording
list and so on. Based on server end, the PVR function will realize

downloading business with DRM data protecting function.

of a variety of program formats as well as the resumption of downloading
after pausing. Meanwhile, the programs downloaded can be encrypted
through standard DRM system according to the needs of users. Then
network operators are able to pose restriction on their watching
