A player receives encoded content of a first resolution level from a content retransmitter and monitors bandwidth of the communication connection utilized to receive the content. When the bandwidth changes with respect to various threshold values corresponding to various resolution levels, the player signals the content retransmitter to increase or decrease the encoding resolution for future portions. The player also locates related substitute content. When the player signals the content retransmitter to decrease the resolution below a minimum, the player plays the substitute content instead of the received content. Subsequently when the bandwidth is again such that player signals the content retransmitter to increase the resolution to the minimum or above, the player plays the received content instead of the substitute content. In various implementations, the player may obtain substitute content prior to or at the time the player determines to play substitute content.

A scheme for managing ABR streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless UE device executing an ABR client application is in a radio white spot area, the current ABR streaming session may be suspended at a particular segment. Thereafter, playback of other content locally cached at the wireless UE device may be commenced in lieu of the ABR media segments. When the wireless UE device exits the radio white spot area, the ABR streaming session may be resumed from a point adjacent to the particular segment where the ABR streaming session was suspended.

A method is provided for accessing a multimedia content containing at least one data segment. This data segment is accessible via a document describing the content. The method includes a first step of obtaining the document describing the content, from which document at least a first universal address of a segment is generated; a second step of obtaining at least one parameter associated with the universal address of the document describing the content; a step of reading at least one address generator rule in the document describing the content; and as a function of the address generator rule, of the first universal address of the segment, and of the parameter that has been obtained, a last step of generating the second universal address for the segment. Also provided is a method of generating a document that is suitable for use in the context of the access method.

Systems and methods for real-time transmission of data streams are disclosed. A controller receives data representing selected stream parameters from a browser residing on a computing device. The controller transmits the received data to a video transmitting device. A transcoder receives a first data stream generated according to the selected stream parameters from the video transmitting device. The transcoder generates a second data stream from the first data stream, the second data stream formatted for browser display; and then transmits the second data stream to the browser. A user may remotely control the video transmitting device using the browser. A user may view data streams from multiple video transmitting devices using the browser.
