| Summary |
For any digital TV developer or manager, the maze of standards and specifications related to MHP and OCAP is daunting-you have to patch together pieces from several standards to gather all the necessary knowledge you need to compete worldwide. The standards themselves can be confusing, and contain many inconsistencies and missing pieces. Interactive TV Standards provides a guide for actually deploying these technologies for a broadcaster or product and application developer. Understanding what the APIs do is essential for your job, but understanding how the AP. |
