Question 4

RTMFP

Answer 4

Real Time Message Flow Protocol 
Adobe
UDP
Adds Player to player communication
Flash Player 10, AIR 1.5

Question 5

RTMP

Answer 5

This is the standard, unencrypted Real-Time Messaging Protocol. The default port is 1935; if a port is not specified, the client attempts to connect to ports in the following order: 1935, 443, 80 (RTMP), 80 (RTMPT).

Question 6

RTMPT

Answer 6

his protocol is RTMP tunneled over HTTP; the RTMP data is encapsulated as valid HTTP. The default port is 80.

Question 7

RTMPS

Answer 7

This protocol is RTMP over SSL. SSL is a protocol for enabling secure communications over TCP/IP. (Adobe Media Server provides native support for both incoming and outgoing SSL connections.) The default port is 443.

Question 8

RTMPE

Answer 8

This protocol is an encrypted version of RTMP. RTMPE is faster than SSL, does not require certificate management, and is enabled in the server’s Adaptor.xml file. If you specify RTMPE without explicitly specifying a port, the Flash Player scans ports just like it does with RTMP, in the following order: 1935 (RTMPE), 443 (RTMPE), 80 (RTMPE), and 80 (RTMPTE).

Question 9

RTMPTE

Answer 9

This protocol is RTMPE with an encrypted tunneling connection. The default port is 80.

Question 10

HDS

Answer 10

HTTP Dynamic Streaming
packages media files into fragments that Flash Player clients can access instantly without downloading the entire file. Adobe HTTP Dynamic Streaming contains several components that work together to package media and stream it over HTTP to Flash Player.

Question 11

Progressive Download

Answer 11

The content must transfer from the server to the client in a progression from the beginning to the end of a file. A client cannot seek to a forward location until that location and all the data before it has downloaded.

Question 12

Stream “RTMP”

Answer 12

The media server (such as Adobe Media Server) creates a socket connection to the client over which the content is sent in a continuous stream. The client can seek to any point in the content instantly, regardless of how much data has been transferred.

Question 13

HLS

Answer 13

Apple HTTP Live Streaming

same as HDS from Adobe, but targeted for iOS

Question 14

FLV

Answer 14

All versions of Adobe Media Server support playback and recording of the FLV file format. On-demand, real-time HTTP Dynamic Streaming does not support the FLV format.

Question 15

F4V (MPEG-4 compatible)

Answer 15

playback of all Adobe Media Server-supported audio and video codecs within MPEG-4 Part 12 container formats. File types supported by the MPEG-4 format include F4V, MP4, M4A, MOV, MP4V, 3GP, and 3G2.

Question 16

MP3

Answer 16

The MPEG Layer-3 (mp3) file format is an audio file format that uses lossy data compression.

Question 17

RAW

Answer 17

The RAW (Record and Watch) file format records media into configurable chunks that stream to any version of Flash Player.

Question 18

F4M

Answer 18

The Adobe Media Manifest file format contains information about a Adobe Media asset. Manifest information includes the location of media, codecs, resolutions, and the availability of files encoded at multiple bit rates, DRM authentication information, and so on. Use the F4M file format for HTTP Dynamic Streaming.

Question 19

F4F

Answer 19

The F4F file format describes how to divide media content into segments and fragments. Each fragment has its own bootstrap information that provides cache management and fast seeking. Use the F4F file format for HTTP Dynamic Streaming.

Question 20

XMP

Answer 20

embedded metadata information in the media file
