Summary

In this contribution,

s
yndication capability

for m
etadata
is newly proposed
to
be
added on
the figure
5.3
,


Metadata
flows in Serv
ice Navigation System


in service navigation system

.



Discussion

Metadata service is overviewed in IPTV metadata
to support IPTV service

(
FG IPTV
-
DOC
-

9).
And
metadata based
service
navigation

is also
described
o
n service nav
igation system,
FG IPTV
-
DOC
-

.
Metadata is necessary for interactive IPTV data
s
ervice.
B
elow
are r
elate
d

texts with
metadata in
WG6.

-

In
FG IPTV
-
DOC
-
009
9 WD (IPTV metadata), metadata server and
metadata

client are described
for metadata service. On s
ection 2, it describes that metadata is necessary to support for user
preference or context. And

on section 7
,
metadata elements are described for service and content
metadata.

WD (Service Navigation System), metadata is based on XML

mechanism
to support Navigation Functional Entity on section 5.2.2.


As well,
EPG metadata capabilities are listed for retrieval and customization in
FG IPTV
-
DOC
-
0095
. Customization includes on
-
demand feeding, filtering and gathering with metadata. To su
pport
such services, metadata syndication capability is
necessary
.

Syndication, for example
RSS

(
"Really
Simple Syndication"
) in Web
,

is a family of
web feed

formats used to publish freque
ntly updated
content. An RSS document contains either a summary of content from an associated web site or the
full text
.
RSS formats are specified using
XML
, a generic specification for the creation

of data
formats
.

-

In FG IPTV
-
DOC
-
0095
WD (IPTV middleware, Application and Content Platforms),

some
guidelines

about EPG capabilities are described on section 13. Among them, some features listed on
EPG metadata capabilities for retrieval and customizat
ion
. R
etrieval includes fast search, semantic
search. Customization includes on
-
demand feeding, filtering and gathering for metadata.

Metadata flows in Service Navigation Systems


Browser
is IPTV
client module that loads and renders
web pages encoded

in
a mark
-
up language

mostly based on HTML/XML,

and a scripting language.

Navigation f
ront
-
end serves navigation
information (e.g. metadata)

and client side scripts on
requests from
cli
ent side application

in IPTV client.

Metadata
can also be received from a video head
-
end and
cached or processed in middleware
.

Client side
application

is executed locally to control the navigati
on user interface.
Client side
application
can retrieve meta
data directly from the front
-
end
or
through middleware

from local
cache
.

Syndication controller

provides

metadata adaptation function with metadata DB
and manages
metadata
with
b
rowser syndication engine
. It
classifies

and customizes metadata from IPTV
met
adata DB for

web browser in IPTV terminal
.
T
h
e data format between s
yndication controller
and syndication engine could be standardized syndication format such as
RSS/Atom
.


Syndication engine

in
b
rowser
manages the metadata information from server side and

it can
provide the aggregated feeding and customized retrieval of metadata information.
