## 5.7\. Network Protocols

Device implementations MUST support the [media network protocols](
http://developer.android.com/guide/appendix/media-formats.html)
for audio and video playback as specified in the Android SDK documentation.

If device implementations include an audio or a video decoder, they:

*    [C-1-1] MUST support all required codecs and container formats in
[section 5.1](#5_1_media_codecs) over HTTP(S).

*    [C-1-2] MUST support the media segment formats shown in
the Media Segment Formats table below over
[HTTP Live Streaming draft protocol, Version 7](
http://tools.ietf.org/html/draft-pantos-http-live-streaming-07).

*    [C-1-3] MUST support the following RTP audio video profile and related
codecs in the RTSP table below. For exceptions please see the table footnotes
in [section 5.1](#5_1_media_codecs).
