Oracle Video Server (OVS)
2-2 Introducing Oracle Video Server
Oracle Video Server (OVS)
The Oracle Video Server (OVS) is a scalable video software engine that stores video
on a video server computer and can deliver the video to multiple concurrent clients
in real time. This chapter uses the term video to refer to any data streamed in real
time, including digitized video and/or audio.
This section describes these OVS features and benefits:
■
Content
■
Storage
■
Delivery

Content
The video that the OVS stores and delivers to clients is called content. The OVS
stores content in these forms:
■
Physical Content — the actual physical files containing multimedia data
■
Logical Content — logical representations of the physical data that you can
define to customize the multimedia data your clients can request
Physical Content
Physical video content files are created from actual video through a process called
encoding
performed by a third-party encoding software or hardware called a codec
that is not part of the OVS. To create content, the encoder uses these formats:
■
The way in which an encoder compresses video frames so they use less space is
called a
compression format
or a codec.
■
The way in which an encoder multiplexes, or puts together, video and audio is
called a
container or mux format .
Compression Formats The OVS can stream many compression formats including:
■
MPEG (Motion Pictures Experts Group)
■
Iterated Systems ClearVideo
■
Radius CinePak
■
Intel Indeo
■
Motion JPEG (Joint Photographic Experts Group)
