An MPEG object is an object-oriented data structure that may be used in the creation of interactive MPEG video stream. The MPEG object data structure includes an MPEG object interface defining data received by the MPEG object and data output by the MPEG object. The MPEG object data structure further includes either one or more MPEG video elements or an association to one or more MPEG video elements. The MPEG video elements are preferably defined as MPEG slices that include a plurality of encoded macroblocks. Additionally, the data structure may provide a method for receiving input through the MPEG object interface and in response to input from the client device outputting an MPEG video element. In certain configurations, the MPEG object contains a method that maintains state data for the MPEG object. The state data may be used to select between a plurality of MPEG elements to output. In other configurations, the MPEG object includes a method that provides for the control of streaming MPEG content from a source external to the MPEG object.

Provided are a method and device for processing messages of IPTV. The method includes: acquiring multiple EPG versions which simultaneously exist; acquiring one or more corresponding view types according to the multiple EPG versions, wherein a group of EPG versions to be processed in a same manner are set to collectively correspond to one view type; and processing request messages of the multiple EPG versions according to the one or more view types. By means of the solution, the problem in the relevant art that services cannot be processed normally due to the service upgrade in batches of the IPTV is solved, thereby providing a technical basis for achieving the service upgrade of an IPTV system in batches, so that the losses of benefits and operation of an operator caused by the upgrade can be decreased and reduced to the maximum extent, and a favorable service experiences are ensured for users.
