Overview
Purpose
This document explains the APIs provided by the SARA DVR recording system,
so that application developers can create an application for users to manage their
DVR remotely.
Scope
This document presents the APIs available to develop an application to access the
SARA DVR information. There is no user authentication or security provided by
these APIs.
In addition, the act of enabling DVR recording management over the network
In addition, the act of enabling DVR recording management over the network
implies a load on the network capabilities of the DBDS network. This document
does not address the network impact analysis, because the network architecture
will vary for each service provider.
A guiding principle is to transfer the minimal amount of data across the network
A guiding principle is to transfer the minimal amount of data across the network
to reduce the bandwidth usage for remote DVR management applications.
In addition, this document makes the following assumptions:
In addition, this document makes the following assumptions:
Functionality is for DVR set-tops (STBs) only.
IPG specifics do not need to be sent across the network, because the web
application has access to IPG information. However, the web application may
occasionally need to query information for a single program at a time.
Scheduling capabilities are the same as provided by the SARA UI on a DVR
box. For example, padding of start and end times is not allowed.
Data exchanged between SARA and the Remote DVR application will use
pointers instead of handles.
Audience
This document contains useful information for application developers who create
applications for the DBDS.
