Abstract

Methods, media data structures, and systems are provided for compressing, streaming, and playing media data. Data sections for frames of media data are compared, and similar data sections are stored once in a compressed media data. A meta data structure maps each similar data section in the compressed media data to its appropriate frame in the media data. A media player that is self-loading and executing is transmitted to a recipient. In one embodiment, the media player detects a network data transmission rate and configures accordingly. Next, the media player requests the meta data structure and the compressed media data and automatically begins receiving, decompressing, and playing the frames of the media data.

Claims

1. A machine-implemented method, comprising:

receiving a media stream having a media player attached on a front-end of the media stream, wherein the media stream also includes media data that the media player is to play and includes metadata associated with decompressing frames of the media data, and wherein the metadata provides a mapping for similar data sections appearing in the media data, each similar data section is stored once in the metadata and is mapped to a plurality of media data frames in the media data, and wherein similar means that data sections are identical and stored once in the metadata, the metadata is a character string having numerical positional values that provide the mappings for the similar data sections appearing in the media data, the mappings permit each data section to be populated out of the metadata from a single location to multiple locations within the media data belonging to specific frames of the media data when the metadata is decompressed;

automatically loading and executing the media player from the front-end of the media stream; and

using the media player to control a remaining portion of the media stream being delivered to a machine that executes the media player.

2. The method of claim 1 further comprising, acquiring, by the media player, the metadata that defines a compression technique used for the remaining portion of the media stream.

3. The method of claim 2 further comprising, decompressing the remaining portion of the media stream by processing a decompression technique that corresponds to the compression technique identified in the metadata.

4. The method of claim 1 further comprising, dynamically playing the remaining portion of the media stream with the media player.

5. The method of claim 1 further comprising, defining, by the media player, a transmission rate associated with delivering the remaining portion of the media stream.

6. The method of claim 1 further comprising, detecting by the media player environment settings of the machine and using those settings to control delivery of the remaining portion of the media stream.

7. The method of claim 1 further comprising, enforcing, by the media player licensing restrictions defined by metadata associated with the remaining portion of the media stream.

8. A machine-implemented system, comprising:

a media player;

metadata; and

compressed media data, wherein the media player is to be attached to a beginning portion of the compressed media data along with the metadata, and wherein the media player is to self load and to self install within a recipient browser and is to consume the metadata for purposes of controlling delivery of a remaining portion of the compressed media data, which is to be streamed to a recipient machine that executes the media player, and wherein the compressed media data, the metadata, and the media player are all part of a metadata structure and streamed together to the recipient machine, and wherein the metadata structure provides a mapping for similar data sections appearing in the media data, each similar data section is stored once in the metadata and is mapped to a plurality of media data frames in the media data, and wherein the metadata is a character string having numerical positional values that provide the mappings for the similar data sections appearing in the media data, the mappings permit the similar data sections appearing once in the metadata to be populated to multiple frames in the media data when the metadata is decompressed;

wherein the media player is to consume the metadata to decompress the remaining portion of the media data and to play decompressed portions of the media data.

9. The system of claim 8, wherein the media player is to detect and adjust a transmission rate associated with delivering the remaining portion of the compressed media data to the machine.

10. The system of claim 8, wherein the metadata is to define block sizes and compression techniques associated with the compressed media data for the media player.

11. The system of claim 8, wherein the media player unloads itself from the machine once the compressed media data has played on the machine.

12. The system of claim 8, wherein the media player is to report usage statistics associated with playing the media data to a media source that provides the compressed media data.
